Full Text Available Background & objectives: An outbreak of acute encephalitis syndrome was reported from Vidarbha region of Maharashtra s0 tate, India, during July 2012. Anti-IgM antibodies against Chandipura virus (CHPV were detected in clinical samples. Sandfly collections were done to determine their role in CHPV transmission. Methods: Twenty nine pools of Sergentomyia spp. comprising 625 specimens were processed for virus isolation in Vero E6 cell line. Diagnostic RT-PCR targeting N-gene was carried out with the sample that showed cytopathic effects (CPE. The PCR product was sequenced, analysed and the sequences were deposited in Genbank database. Results: CPE in Vero E6 cell line infected with three pools was detected at 48 h post infection. However, virus could be isolated only from one pool. RT-PCR studies demonstrated 527 nucleotide product that confirmed the agent as CHPV. Sequence analysis of the new isolate showed difference in 10-12 nucleotides in comparison to earlier isolates. Interpretation & conclusions: This is perhaps the first isolation of CHPV from Sergentomyia spp. in India and virus isolation during transmission season suggests their probable role in CHPV transmission. Further studies need to be done to confirm the precise role of Sargentomyia spp. in CHPV transmission.

Full Text Available Infectious Bovine Rhinotracheitis, caused by Bovine Herpesvirus-1 (BoHV-1 maintains latency in trigeminal nerve ganglia of bovine. The sero-positive bull infected with BoHV-1 secretes the virus through semen intermittently, when the immune system is compromised. Sera from bulls housed at different bull stations were analyzed using gE protein specific IDEXX Kit, which showed 78.69% positivity. Each batch of semen from sero-positive bull was investigated further for presence of virus in semen by Real Time-PCR technique for validation of presence of virus in the frozen semen doses using gB specific primers and probe, which showed 0.968 % semen batches positive. This study showed that despite high sero prevalence in bull, the semen excretes very negligible amount of the virus indicating the subtypes circulating in farms of West Bengal, India is assumed to be respiratory type.

Full Text Available Dengue fever is the most important arboviral disease in the tropical and sub-tropical countries of the world. Delhi, the metropolitan capital state of India, has reported many dengue outbreaks, with the last outbreak occurring in 2013. We have recently reported predominance of dengue virus serotype 2 during 2011-2014 in Delhi. In the present study, we report molecular characterization and evolutionary analysis of dengue serotype 2 viruses which were detected in 2011-2014 in Delhi. Envelope genes of 42 DENV-2 strains were sequenced in the study. All DENV-2 strains grouped within the Cosmopolitan genotype and further clustered into three lineages; Lineage I, II and III. Lineage III replaced lineage I during dengue fever outbreak of 2013. Further, a novel mutation Thr404Ile was detected in the stem region of the envelope protein of a single DENV-2 strain in 2014. Nucleotide substitution rate and time to the most recent common ancestor were determined by molecular clock analysis using Bayesian methods. A change in effective population size of Indian DENV-2 viruses was investigated through Bayesian skyline plot. The study will be a vital road map for investigation of epidemiology and evolutionary pattern of dengue viruses in India.

Full Text Available Background & objectives: Recent influenza antiviral resistance studies in South East Asia, Europe and the United States reveal adamantane and neuraminidase inhibitor (NAIs resistance. This study was undertaken to evaluate antiviral resistance in influenza viruses isolated from various parts of India, during 2004 to 2011. Methods: Influenza viruses were analyzed genetically for known resistance markers by M2 and NA gene sequencing. Influenza A/H1N1 (n=206, A/H3N2 (n=371 viruses for amantadine resistance and A/H1N1 (n=206, A/H3N2 (n=272 and type B (n=326 for oseltamivir resistance were sequenced. Pandemic (H1N1 (n= 493 isolates were tested for H274Y mutation by real time reverse transcription (rRT-PCR. Randomly selected resistant and sensitive influenza A/H1N1 and A/H3N2 viruses were confirmed by phenotypic assay. Results: Serine to asparagine (S3IN mutation was detected in six isolates of 2007-2008.One dual-resistant A/H1N1 was detected for the first time in India with leucine to phenylalanine (L26F mutation in M2 gene and H274Y mutation in NA gene. A/H3N2 viruses showed an increase in resistance to amantadine from 22.5 per cent in 2005 to 100 per cent in 2008 onwards with S3IN mutation. Fifty of the 61 (82% A/H1N1 viruses tested in 2008-2009 were oseltamivir resistant with H274Y mutation, while all A/H3N2, pandemic A/H1N1 and type B isolates remained sensitive. Genetic results were also confirmed by phenotypic analysis of randomly selected 50 resistant A/H1N1 and 40 sensitive A/H3N2 isolates. Interpretation & conclusions: Emergence of influenza viruses resistant to amantadine and oseltamivir in spite of negligible usage of antivirals emphasizes the need for continuous monitoring of antiviral resistance.

Banana bunchy top disease (BBTD) caused by Banana bunchy top virus (BBTV) is one of the most devastating diseases of banana and poses a serious threat for cultivars like Hill Banana (Syn: Virupakshi) and Grand Naine in India. In this study, we have cloned and sequenced the complete genome comprised of six DNA components of BBTV infecting Hill Banana grown in lower Pulney hills, Tamil Nadu State, India. The complete genome sequence of this hill banana isolate showed high degree of similarity with the corresponding sequences of BBTV isolates originating from Lucknow, Uttar Pradesh State, India, and from Fiji, Egypt, Pakistan, and Australia. In addition, sixteen coat protein (CP) and thirteen replicase genes (Rep) sequences of BBTV isolates collected from different banana growing states of India were cloned and sequenced. The replicase sequences of 13 isolates showed high degree of similarity with that of South Pacific group of BBTV isolates. However, the CP gene of BBTV isolates from Shervroy and Kodaikanal hills of Tamil Nadu showed higher amino acid sequence variability compared to other isolates. Another hill banana isolate from Meghalaya state had 23 nucleotide substitutions in the CP gene but the amino acid sequence was conserved. This is the first report of the characterization of a complete genome of BBTV occurring in the high altitudes of India. Our study revealed that the Indian BBTV isolates with distinct geographical origins belongs to the South Pacific group, except Shervroy and Kodaikanal hill isolates which neither belong to the South Pacific nor the Asian group.

Hepatitis B virus (HBV) and hepatitis C virus (HCV) have several important similarities including worldwide distribution, hepato-tropism, similar modes of transmission and the ability to induce chronic infection that may lead to liver cirrhosis and hepatocellular carcinoma. Since both viruses are individually known to cause the pathologies mentioned above, co-infection with both HBV and HCV would be expected to be linked with higher morbidity as well as mortality and impact healthcare resource utilisation. Precise estimate of the prevalence of HBV/HCV co-infection would be needed to formulate policy decisions and plan communal health interventions. This systematic review and meta-analysis, therefore, aims to understand the prevalence of HBV and HCV co-infection in India based on the available literature. Following PRISMA guidelines, primary studies reporting the prevalence of HBV/HCV co-infection in India were retrieved through searches conducted in PubMed, Google SCHOLAR, Medline, Cochrane Library, WHO reports, Indian and International journals online. All online searches were conducted between December 2016 and February 2017. Meta-analysis was carried out using StatsDirect statistical software. Thirty studies published between 2000 and 2016 conducted across six regions of India were included in this review. The pooled HBV/HCV co-infection prevalence rate across the thirty studies was 1.89% (95% confidence intervals [CI] = 1.2%-2.4%). A high heterogeneity was observed between prevalence estimates. The HBV/HCV co-infection prevalence in different subgroups varied from 0.02% (95% CI = 0.0019%-0.090%) to 3.2% (95% CI = 1.3%-5.9%). The pooled prevalence of HBV/HCV co-infection in India was found to be 1.89%. This systematic review and meta-analysis revealed high prevalence of HBV/HCV co-infection in chronic liver patients, followed by HIV-positive patients, and then followed by persons who inject drugs and kidney disease patients.

Acute viral hepatitis (AVH) is a major public health problem and is an important cause of morbidity and mortality. The aim of the present study is to determine the prevalence of hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and hepatitis E virus (HEV) as causes of AVH in a tertiary care hospital of North India. Blood samples and clinical information was collected from cases of AVH referred to the Grade I viral diagnostic laboratory over a 1-year period. Samples were tested for hepatitis B surface antigen, anti-HCV total antibodies, anti-HAV immunoglobulin M (IgM) and anti-HEV IgM by the enzyme-linked immunosorbent assay. PCR for nucleic acid detection of HBV and HCV was also carried out. Those positive for HBV infection were tested for anti-HDV antibodies. Fisher's exact test was used and a P hepatitis cases, 62 (23.22%) patients presented as acute hepatic failure. HAV (26.96%) was identified as the most common cause of acute hepatitis followed by HEV (17.97%), HBV (16.10%) and HCV (11.98%). Co-infections with more than one virus were present in 34 cases; HAV-HEV co-infection being the most common. HEV was the most important cause of acute hepatic failure followed by co-infection with HAV and HEV. An indication towards epidemiological shift of HAV infection from children to adults with a rise in HAV prevalence was seen. To the best of our knowledge, this is the first report indicating epidemiological shift of HAV in Uttar Pradesh.

Newly emerging and re-emerging viral infections are of major public health concern. Bunyaviridae family of viruses comprises a large group of animal viruses. Clinical symptoms exhibited by persons infected by viruses belonging to this family vary from mild-to-severe diseases i.e., febrile illness, encephalitis, haemorrhagic fever and acute respiratory illness. Several arthropods-borne viruses have been discovered and classified at serological level in India in the past. Some of these are highly pathogenic as the recent emergence and spread of Crimean-Congo haemorrhagic fever virus and presence of antibodies against Hantavirus in humans in India have provided evidences that it may become one of the emerging diseases in this country. For many of the discovered viruses, we still need to study their relevance to human and animal health. Chittoor virus, a variant of Batai virus; Ganjam virus, an Asian variant of Nairobi sheep disease virus; tick-borne viruses such as Bhanja, Palma and mosquito-borne viruses such as Sathuperi, Thimiri, Umbre and Ingwavuma viruses have been identified as the members of this family. As Bunyaviruses are three segmented RNA viruses, they can reassort the segments into genetically distinct viruses in target cells. This ability is believed to play a major role in evolution, pathogenesis and epidemiology of the viruses. Here, we provide a comprehensive overview of discovery, emergence and distribution of Bunyaviruses in India.

Hepatitis A is endemic in India and mainly causes sporadic infections. However, children in childcare centers, schools and orphanages are vulnerable to common-source outbreaks as they have naive hosts. To investigate hepatitis A outbreak in an orphanage from Pune, India. Monitoring of virus excretion and anti-HAV antibody levels in hepatitis A virus (HAV) infected children. The orphanage housed 93 children of the age 1 month-6.5 years. Analysis of the collected serum (n=78) and stool samples (n=63) revealed 20 children to be either positive for anti-HAV IgM antibodies or excreting HAV, 14 being symptomatic and 6 asymptomatic, while 32 were already anti-HAV IgG positive either due to past HAV exposure (n=7, mean log antibody titers: 2.96) or maternal antibodies (n=25, mean log antibody titers: 1.13). Serum samples, taken 4 weeks apart, did not show any significant difference in the IgM and IgG antibody levels either. However, virus excretion decreased significantly after 15 days in symptomatic children (mean log HAV RNA copies/ml 1.03+0.30), while asymptomatic children continued to excrete higher viral loads, at constant levels (mean log HAV RNA copies/ml 2.33+0.33), for up to 90 days. Though virus excretion continued up to 90 days in all HAV infected children, asymptomatic children excreted higher viral loads for longer period and hence can contribute significantly in person-to-person virus transmission. All children should be vaccinated in such set ups. Copyright © 2015 Elsevier B.V. All rights reserved.

Classical swine fever (CSF) is a highly contagious and the most important disease of pigs worldwide.CSF is enzootic in pig herds in India and continues to cause huge economic losses to pig farmers. Nearly 40% of the total pig population of India is present in the north-eastern (NE) states where pig husbandry plays an important role in the socio-economic development. Pigs reared in the backyards are the only source of livelihood for a majority of poor tribal population in the region. Hardly any CSF vaccination is currently being undertaken in the unorganized pig farming in the NE region due to economic reasons and vaccine unavailability. A thorough understanding of the current epidemiological status of CSF is essential for the effective control of the disease in the NE region. Hence, we carried out molecular characterization of CSFV isolates from field outbreaks during 2011-2012 in the entire north-eastern region of India to establish the genetic groups of prevalent CSF viruses in the region. A total of 17 CSFV isolates obtained from different parts of the NE region were characterized by comparing the sequences of three partial genomic regions of the virus, that is 150 nt of 5' UTR, 190 nt of E2 and 409 nt of NS5B. Of the 17 CSFV isolates, 15 isolates belonged to 1.1 (88.2%) and two isolates (11.8%) belonged to 2.2 subgenogroup. The genogroup 2.2 CSFV were associated with outbreaks in Arunachal Pradesh that shares international borders with Bhutan, Myanmar and China. Genogroup 2.2 CSFV isolated in the present study shared high level of sequence similarity with 2.2 viruses form China, raising the possibility of virus incursion from this region. In summary, we found a continued predominance of 1.1 subgroup and an emergence of 2.2 subgroup CSFV in NE region of India. © 2014 Blackwell Verlag GmbH.

Full Text Available BACKGROUND: In January 2011, human cases with hemorrhagic manifestations in the hospital staff were reported from a tertiary care hospital in Ahmadabad, India. This paper reports a detailed epidemiological investigation of nosocomial outbreak from the affected area of Ahmadabad, Gujarat, India. PRINCIPAL FINDINGS: Samples from 3 suspected cases, 83 contacts, Hyalomma ticks and livestock were screened for Crimean-Congo hemorrhagic fever (CCHF virus by qRT-PCR of which samples of two medical professionals (case C and E and the husband of the index case (case D were positive for CCHFV. The sensitivity and specificity of indigenous developed IgM ELISA to screen CCHFV specific antibodies in human serum was 75.0% and 97.5% respectively as compared to commercial kit. About 17.0% domestic animals from Kolat, Ahmadabad were positive for IgG antibodies while only two cattle and a goat showed positivity by qRT-PCR. Surprisingly, 43.0% domestic animals (Buffalo, cattle, sheep and goat showed IgG antibodies in the adjoining village Jivanpara but only one of the buffalo was positive for CCHFV. The Hyalomma anatolicum anatolicum ticks were positive in PCR and virus isolation. CCHFV was isolated from the blood sample of case C, E in Vero E-6 cells and Swiss albino mice. In partial nucleocapsid gene phylogeny from CCHFV positive human samples of the years 2010 and 2011, livestock and ticks showed this virus was similar to Tajikistan (strain TAJ/H08966, which belongs in the Asian/middle east genetic lineage IV. CONCLUSIONS: The likely source of CCHFV was identified as virus infected Hyalomma ticks and livestock at the rural village residence of the primary case (case A. In addition, retrospective sample analysis revealed the existence of CCHFV in Gujarat and Rajasthan states before this outbreak. An indigenous developed IgM ELISA kit will be of great use for screening this virus in India.

Herpes simplex virus type-2 (HSV-2) is one of the most common sexually transmitted infections that facilitate human immunodeficiency virus (HIV) acquisition by over two fold or more. The development of HSV-2 control methods as a measure to control HIV epidemic in high HSV-2/HIV areas has become a priority. Two out of the six high HIV prevalent states of India are located in the Northeastern region of India. Due to lack of documented HSV-2 studies from this part of the country; there was a need for estimating the seroprevalence and risk factors of HSV-2 infection in this defined population. Pregnant women (n = 1640) aged18 years and above attending antenatal clinics of tertiary referral hospitals in five Northeastern states of India were screened for type specific HSV-2 IgG antibodies. Blood samples were collected from all the participants after conducting interviews. Univariate and multivariate analyses were performed to identify the risk factors associated with HSV-2 seropositivity. Overall seroprevalence of HSV-2 infection was 8.7% (142/1640; 95% CI 7.3-10.0) with a highest prevalence of 15.0% (46/307; 95% CI 11.0-19.0) in the state of Arunachal Pradesh. Higher seroprevalence was observed with increasing age (Adj. Odds Ratio [AOR] 1.9 for 22-25 years old, AOR 2.29 for > 29 years old). The risk factors associated with HSV-2 seropositives were multiple sex partners (AOR 2.5, p = 0.04), condom non-user's (AOR 4.7, p women of Northeast India is relatively low. The generation of awareness among high risk groups may have played key role to limit the infection. The role of vaccination against HSV-2 in near future and elimination of HSV-2 viral shedding along with genital tract inflammation in high HIV/HSV-2 areas may be an option for initiating successful intervention strategies to reduce the transmission and acquisition of HIV infection in Northeast India.

Our understanding on the importance of viral lysis in the functioning of tropical estuarine ecosystem is limited. This study examines viral infection of prokaryotes and subsequent lysis of cells belonging to different morphotypes across a salinity gradient in monsoon driven estuarine ecosystem (Cochin estuary, India). High standing stock of viruses and prokaryotes accompanied by lytic infection rates in the euryhaline/mesohaline region of the estuary suggests salinity to have an influential role in driving interactions between prokaryotes and viruses. High prokaryotic mortality rates, up to 42% of prokaryote population in the pre-monsoon season is further substantiated by a high virus to prokaryote ratio (VPR), suggesting that maintenance of a high number of viruses is dependent on the most active fraction of bacterioplankton. Although myoviruses were the dominant viral morphotype (mean = 43%) throughout the study period, there was significant variation among prokaryotic morphotypes susceptible to viral infection. Among them, the viral infected short rod prokaryote morphotype with lower burst estimates (mean = 18 viruses prokaryote-1) was dominant (35%) in the dry seasons whereas a substantial increase in cocci forms (30%) infected by viruses with high burst size (mean = 31 viruses prokaryote-1) was evident during the monsoon season. Such preferential infections of prokaryotic morphopopulations with respect to seasons can have a strong and variable impact on the carbon and energy flow in this tropical ecosystem.

Ganjam virus (GANV), a member of genus Nairovirus of family Bunyavirdae is of considerable veterinary importance in India. Though, predominantly tick borne, GANV was also isolated from mosquitoes, man and sheep. Neutralizing and complement fixing antibodies to GANV have been detected in animal and human sera collected from different parts of the country. Thirty three strains of GANV have been isolated from India, mainly from Haemaphysalis ticks. The virus replicated in certain vertebrate and mosquito cell lines and found pathogenic to laboratory animals. One natural infection and five laboratory-acquired infections in men were also reported. GANV is antigenically related to Nairobi sheep disease virus (NSDV) of Africa, which is highly pathogenic for sheep and goats causing 70-90 per cent mortality among the susceptible population. Recent molecular studies have demonstrated that GANV is an Asian variant of NSDV and both these viruses are related to the dreaded Crimean Congo haemorrhagic fever (CCHF) group viruses. The versatility of the virus to replicate in different arthropod species, its ability to infect sheep, goat and man makes it an important zoonotic agent.

In recent times, majority of the foot-and-mouth disease (FMD) outbreaks in India are caused by serotype O Ind2001 lineage. The lineage has diverged into four sub-lineages (Ind2001a, b, c and d). We report here the genetic and antigenic analyses of nine Ind2001d isolates that caused outbreaks during April 2013-March 2014 in India. The length of the genomes of outbreak viruses varied between 8153 and 8181 nucleotides without any insertion or deletion in the coding region. Of the nine isolates analyzed antigenically against the currently used Indian vaccine strain INDR2/1975, eight showed good cross serological match (>0.3) indicating optimal antigenic coverage by the vaccine strain. An unprecedented deletion of 22 nucleotides between position 57 and 78 was observed in the 3' untranslated region of one of the isolates without compromising the virus viability, which imply that partial distortion in SL2 of 3'UTR may not have influence on virus viability at least under in-vitro conditions. Recently the Ind2001 lineage has been reported from several countries including Libya and spread of this lineage across a wide geographical area needs to be monitored carefully to avoid any future pandemic.

Foot-and-mouth disease virus (FMDV) serotype Asia1 was first reported in India in 1951, where three major genetic lineages (B, C and D) of this serotype have been described until now. In this study, the capsid protein coding region of serotype Asia1 viruses (n = 99) from India were analyzed, giving importance to the viruses circulating since 2007. All of the isolates (n = 50) recovered during 2007-2013 were found to group within the re-emerging cluster of lineage C (designated as sublineage C(R)). The evolutionary rate of sublineage C(R) was estimated to be slightly higher than that of the serotype as a whole, and the time of the most recent common ancestor for this cluster was estimated to be approximately 2001. In comparison to the older isolates of lineage C (1993-2001), the re-emerging viruses showed variation at eight amino acid positions, including substitutions at the antigenically critical residues VP279 and VP2131. However, no direct correlation was found between sequence variations and antigenic relationships. The number of codons under positive selection and the nature of the selection pressure varied widely among the structural proteins, implying a heterogeneous pattern of evolution in serotype Asia1. While episodic diversifying selection appears to play a major role in shaping the evolution of VP1 and VP3, selection pressure acting on codons of VP2 is largely pervasive. Further, episodic positive selection appears to be responsible for the early diversification of lineage C. Recombination events identified in the structural protein coding region indicates its probable role in adaptive evolution of serotype Asia1 viruses.

Full Text Available Purpose: Northeast Region of India possesses an abundant number of Aedes mosquitoes, the common vector for Dengue and Chikungunya (CHIK. Dengue is reported every year from Assam, but active surveillance for CHIK virus (CHIKV infection is lacking in this part of India. Therefore, this present study has been undertaken to detect any CHIKV infection during a dengue outbreak in Assam. Materials and Methods: A total of 42 dengue negative samples collected from Guwahati were screened for the presence of CHIK IgM antibodies. Further, all the samples were processed for CHIKV RNA detection by reverse transcriptase-polymerase chain reaction (RT-PCR. Phylogenetic analysis was done by Maximum Likelihood method using Kimura-2 parameter model. Results: No IgM positivity was found in the processed samples; however, 7 samples were positive for CHIKV by RT-PCR. Phylogenetic analysis revealed that the circulating CHIKV belonged to Eastern, Central and Southern African genotype. Sequence analysis showed two uniform nucleotide substitutions and very less amino acid substitution. Conclusion: Silent existence of CHIKV beside dengue is reported from this study. Therefore, CHIKV diagnosis should be included as a regular practice for active surveillance of the disease and its accomplishment before commencing an outbreak.

The prevalence of human enteric viruses in bivalve molluscan shellfish and shrimp collected off the south west coast of India was studied to assess the extent of fecal pollution of coastal environment. Out of 194 samples analyzed, 37% of oyster, 46% of clam and 15% of shrimp samples were positive for enteroviruses (EV). Adenoviruses (ADV) were detected in 17% of oyster and 27% of clam samples. However, other enteric viruses such as noroviruses (NoV) and hepatitis A virus (HAV) were not detected in any of the samples. High prevalence of EV and ADV was noticed between May to December. Thirty four percent of oyster and 49% of clam samples showed fecal coliform values higher than the limit. MS-2 phage was detected in 57% of oyster and 73% of clam samples. The presence of MS-2 phage and human enteric viruses showed association while fecal coliforms and enteric viruses showed no association. However, 17 samples, which were positive for enteric viruses (EV and ADV), were negative for MS-2 phage.

Genetic characterization of the influenza A pandemic (H1N1 2009 virus isolates from India.

Directory of Open Access Journals (Sweden)

Varsha A Potdar

Full Text Available BACKGROUND: The Influenza A pandemic H1N1 2009 (H1N1pdm virus appeared in India in May 2009 and thereafter outbreaks with considerable morbidity and mortality have been reported from many parts of the country. Continuous monitoring of the genetic makeup of the virus is essential to understand its evolution within the country in relation to global diversification and to track the mutations that may affect the behavior of the virus. METHODS: H1N1pdm viruses were isolated from both recovered and fatal cases representing major cities and sequenced. Phylogenetic analyses of six concatenated whole genomes and the hemagglutinin (HA gene of seven more isolates from May-September 2009 was performed with reference to 685 whole genomes of global isolates available as of November 24, 2009. Molecular characterization of all the 8 segments was carried out for known pathogenic markers. RESULTS: The first isolate of May 2009 belonged to clade 5. Although clade 7 was the dominant H1N1pdm lineage in India, both clades 6 and 7 were found to be co-circulating. The neuraminidase of all the Indian isolates possessed H275, the marker for sensitivity to the neuraminidase inhibitor Oseltamivir. Some of the mutations in HA are at or in the vicinity of antigenic sites and may therefore be of possible antigenic significance. Among these a D222G mutation in the HA receptor binding domain was found in two of the eight Indian isolates obtained from fatal cases. CONCLUSIONS: The majority of the 13 Indian isolates grouped in the globally most widely circulating H1N1pdm clade 7. Further, correlations of the mutations specific to clade 7 Indian isolates to viral fitness and adaptability in the country remains to be understood. The D222G mutation in HA from isolates of fatal cases needs to be studied for pathogenicity.

Dengue virus type 2 (DENV-2) has been associated with severe dengue outbreaks in many countries including India. Its predominance was recorded nearly after a decade in the capital city, Delhi in 2013. The present study characterizes DENV-2 circulated during 2013-2014. Analysis based on envelope (E) gene showed the presence of two clades (I and II) of DENV-2, within the Cosmopolitan genotype. Analysis of time of most recent common ancestor revealed the existence of clade I for more than a decade (95 % HPD 13-16 years) however, clade II showed comparatively recent emergence (95 % HPD 5-13 years). Presence of different clades is of high significance as this may result in increased virus transmission and major outbreaks. Further, the presence of a unique amino acid substitution, Q325H was also observed in an isolate; 14/D2/Del/2013 (KT717981). This substitution falls in immune epitope (epitope id: 150268) and may have important role in host immune response.

An evaluation of 70 accessions of ash gourd germplasm grown at National Bureau of Plant Genetic Resources, New Delhi, India during Kharif season (2010) showed natural occurrence of a yellow stunt disease in three accessions (IC554690, IC036330 and Pusa Ujjwal). A set of begomovirus specific primers used in PCR gave expected amplicon from all the symptomatic plants; however no betasatellite was detected. Complete genome of the begomovirus (DNA-A and DNA-B), amplified through rolling circle amplification, was cloned and sequenced. The begomovirus under study shared high sequence identities to different isolates of Tomato leaf curl New Delhi virus (ToLCNDV) and clustered with them. Among those isolates, the DNA-A and DNA-B of the present begomovirus isolate showed highest 99.6 and 96.8 % sequence identities, respectively with an isolate reported on pumpkin from India (DNA-A: AM286433, DNA-B: AM286435). Based on the sequence analysis, the begomovirus obtained from ash gourd was considered as an isolate of ToLCNDV. Thus, the present findings constitute the first report of occurrence of a new yellow stunt disease in ash gourd from India and demonstrated the association of ToLCNDV with the symptomatic samples. Occurrence of ToLCNDV in ash gourd germplasm not only adds up a new cucurbitaceous host of this virus but also raises the concern about the perpetuation of this virus in absence of its main host tomato and thus has an epidemiological relevance for understanding the rapid spread of this virus in tomato and other hosts in Indian sub-continent.

Cassava mosaic disease is a widespread disease of cassava in south Asia and the African continent. In India, CMD is known to be caused by two single-stranded DNA viruses (geminiviruses), Indian cassava mosaic virus (ICMV) and Sri Lankan cassava mosdaic virus (SLCMV). Previously, the diversity of ICMV and SLCMV in India has been studied using PCR, a sequence-dependent method. To have a more in-depth study of the variability of the above viruses and to detect any novel geminiviruses associated with CMD, sequence-independent amplification using rolling circle amplification (RCA)-based methods were used. CMD affected cassava plants were sampled across eighty locations in nine districts of the southern Indian state of Tamil Nadu. Twelve complete sequence of coat protein genes of the resident geminiviruses, comprising 256 amino acid residues were generated from the above samples, which indicated changes at only six positions. RCA followed by RFLP of the 80 samples indicated that most samples (47) contained only SLCMV, followed by 8, which were infected jointly with ICMV and SLCMV. In 11 samples, the pattern did not match the expected patterns from either of the two viruses and hence, were variants. Sequence analysis of an average of 700 nucleotides from 31 RCA-generated fragments of the variants indicated identities of 97-99% with the sequence of a previously reported infectious clone of SLCMV. The evidence suggests low levels of genetic variability in the begomoviruses infecting cassava, mainly in the form of scattered single nucleotide changes.

Present study was undertaken to investigate the cause of deaths of peafowls in Haryana State. In total, 145 birds were sick and 28 birds were reported dead during July to September 2012. Some of the sick birds were showing signs of shaking of heads, torticollis and paresis. Blood and cloacal swab samples from sick birds along with brain and intestinal tissues from dead birds were collected for further investigation. Although post-mortem examination showed no typical lesions of Newcastle disease virus (NDV) yet raised HI tires against NDV in some serum samples and clinical signs indicated the presence of NDV. One of the brain tissues (NDV/IND2012/01) from the field case was processed and adapted to Vero cell line for virus isolation. The fusion (F) gene based nested RT-PCR (RT-nPCR) confirmed the presence of NDV in all field samples and cell culture isolate. Sequencing of the partial F gene amplicons (216 bp) using the PCR primers as sequencing primers confirmed the PCR results. The deduced amino acid sequences of partial F gene were found to have the amino acid motif (111)GRRQKR/F(117) in the fusion protein cleavage site (FPCS). This amino acid motif is indicative of the velogenic nature of these NDVs. Phylogenetic studies have shown that the virus belonged to class II genotype VII very closely related to virus isolates originated from outbreaks in Western Europe, Israel, Indonesia, Taiwan and India. Phylogenetic grouping of the virus and sequence of FPCS is indicative of pathogenic potential of virus strain circulating in peacocks in Haryana.

2009-02-01

Full Text Available Abstract Background A focal H5N1 outbreak in poultry was reported from Manipur, a north-eastern state, of India, in 2007. The aim of this study was to genetically characterize the Manipur isolate to understand the relationship with other H5N1 isolates and to trace the possible source of introduction of the virus into the country. Results Characterization of the complete genome revealed that the virus belonged to clade 2.2. It was distinctly different from viruses of the three EMA sublineages of clade 2.2 but related to isolates from wild migratory waterfowl from Russia, China and Mongolia. The HA gene, had the cleavage site GERRRRKR, earlier reported in whooper swan isolates from Mongolia in 2005. A stop codon at position 29 in the PB1-F2 protein could have implications on the replication efficiency. The acquisition of polymorphisms as seen in recent isolates of 2005–07 from distinct geographical regions suggests the possibility of transportation of H5N1 viruses through migratory birds. Conclusion Considering that all eight genes of the earlier Indian isolates belonged to the EMA3 sublineage and similar strains have not been reported from neighbouring countries of the subcontinent, it appears that the virus may have been introduced independently.

Molecular characterization of measles viruses is a valuable tool for measuring the effectiveness of measles control and elimination programmes. WHO recommends that virological surveillance be conducted during all phases of measles control to document circulation of indigenous strains and trace future importation. This report describes the genetic characterization of wild type measles viruses from Tamil Nadu, India isolated between January 2005 and January 2006. In the study, 304 suspected measles cases (292 from 56 outbreaks and 12 sporadic cases) were investigated. Blood samples were collected from suspected measles outbreaks and 11 suspected sporadic cases and tested for the presence of measles and rubella specific IgM. Based on serological results, 53 outbreaks were confirmed as measles, 2 as a combination of measles and rubella, and 1 negative for both. Eight sporadic cases were confirmed as measles and one as rubella. Throat swab and urine samples were collected for virus isolation and 28 isolates were obtained. Sequencing and analysis showed that 3 isolates belonged to genotype D4 and 25 to genotype D8. Comparison of the genotype D8 sequences from Tamil Nadu with previously reported genotype D8 sequences from India and abroad showed six distinct clusters with Tamil Nadu strains forming two clusters. This study has established baseline molecular data and is the first report that describes genetic diversity of circulating measles strains in Tamil Nadu, a state in India. D8 has multiple lineages and this has been linked with importation of measles into the USA and UK. Copyright © 2011 Wiley Periodicals, Inc.

Full Text Available Ekta Gupta, Neha Ballani Department of Clinical Virology, Institute of Liver and Biliary Sciences, New Delhi, IndiaAbstract: Dengue fever (DF and dengue hemorrhagic fever (DHF are important arthropod-borne viral diseases. Each year, there are ~50 million dengue infections and ~500,000 individuals are hospitalized with DHF, mainly in Southeast Asia. Dengue in India has dramatically expanded over the last few decades, with rapidly changing epidemiology. The first major DHF outbreak in the entire nation occurred in 1996 by dengue virus serotype 2, and after a gap of almost a decade, the country faced yet another DF outbreak in the year 2003 by dengue virus serotype 3. A dramatic increase in the number and frequency of outbreaks followed, and, at present, in most of the states of India, dengue is almost endemic. At present, all the four serotypes are seen in circulation, but the predominant serotype keeps changing. Despite this trend, surveillance, reporting, and diagnosis of dengue remain largely passive in India. More active community-based epidemiological studies with intensive vector control and initiatives for dengue vaccine development should be geared up to control the spread of dengue in India. We review here the factors that may have contributed to the changing epidemiology of dengue in India.Keywords: dengue, epidemiology, India, pathogenesis, vaccine

Full Text Available Abstract Background Herpes simplex virus type-2 (HSV-2 is one of the most common sexually transmitted infections that facilitate human immunodeficiency virus (HIV acquisition by over two fold or more. The development of HSV-2 control methods as a measure to control HIV epidemic in high HSV-2/HIV areas has become a priority. Two out of the six high HIV prevalent states of India are located in the Northeastern region of India. Due to lack of documented HSV-2 studies from this part of the country; there was a need for estimating the seroprevalence and risk factors of HSV-2 infection in this defined population. Methods Pregnant women (n = 1640 aged18 years and above attending antenatal clinics of tertiary referral hospitals in five Northeastern states of India were screened for type specific HSV-2 IgG antibodies. Blood samples were collected from all the participants after conducting interviews. Univariate and multivariate analyses were performed to identify the risk factors associated with HSV-2 seropositivity. Results Overall seroprevalence of HSV-2 infection was 8.7% (142/1640; 95% CI 7.3-10.0 with a highest prevalence of 15.0% (46/307; 95% CI 11.0-19.0 in the state of Arunachal Pradesh. Higher seroprevalence was observed with increasing age (Adj. Odds Ratio [AOR] 1.9 for 22-25 years old, AOR 2.29 for > 29 years old. The risk factors associated with HSV-2 seropositives were multiple sex partners (AOR 2.5, p = 0.04, condom non-user's (AOR 4.7, p 0.001, early coitarchal age (age of first intercourse 'less than 18 years' (AOR 9.6, p = 0.04, middle income group (AOR 2.1, p = 0.001 compared to low income group and low level of education (AOR 3.7, p = 0.02 compared to higher education. HSV-2 seropositivity was higher among Christians (12.6% compared to Muslims (3.8%. The most frequent clinical symptoms among HSV-2 seropositives were excess vaginal discharge in last one year (53.5%, 76/142 and pelvic pain (26.1%, 37/142. While among subjects with

Viswanathan, R; Balamuralikrishnan, M; Karuppaiah, R

2008-12-01

Sugarcane yellow leaf virus (SCYLV) that causes yellow leaf disease (YLD) in sugarcane (recently reported in India) belongs to Polerovirus. Detailed studies were conducted to characterize the virus based on partial open reading frames (ORFs) 1 and 2 and complete ORFs 3 and 4 sequences in their genome. Reverse-transcriptase polymerase chain reaction (RT-PCR) was performed on 48 sugarcane leaf samples to detect the virus using a specific set of primers. Of the 48 samples, 36 samples (field samples with and without foliar symptoms) including 10 meristem culture derived plants were found to be positive to SCYLV infection. Additionally, an aphid colony collected from symptomatic sugarcane in the field was also found to be SCYLV positive. The amplicons from 22 samples were cloned, sequenced and acronymed as SCYLV-CB isolates. The nucleotide (nt) and amino acid (aa) sequence comparison showed a significant variation between SCYLV-CB and the database sequences at nt (3.7-5.1%) and aa (3.2-5.3%) sequence level in the CP coding region. However, the database sequences comprising isolates of three reported genotypes, viz., BRA, PER and REU, were observed with least nt and aa sequence dissimilarities (0.0-1.6%). The phylogenetic analyses of the overlapping ORFs (ORF 3 and ORF 4) of SCYLV encoding CP and MP determined in this study and additional sequences of 26 other isolates including an Indian isolate (SCYLV-IND) available from GenBank were distributed in four phylogenetic clusters. The SCYLV-CB isolates from this study lineated in two clusters (C1 and C2) and all the other isolates from the worldwide locations into another two clusters (C3 and C4). The sequence variation of the isolates in this study with the database isolates, even in the least variable region of the SCYLV genome, showed that the population existing in India is significantly different from rest of the world. Further, comparison of partial sequences encoding for ORFs 1 and 2 revealed that YLD in sugarcane in

Nairobi sheep disease virus/Ganjam virus.

Nairobi sheep disease virus (NSDV) is a tick-borne virus which causes a severe disease in sheep and goats, and has been responsible for several outbreaks of disease in East Africa. The virus is also found in the Indian subcontinent, where it is known as Ganjam virus. The virus only spreads through the feeding of competent infected ticks, and is therefore limited in its geographic distribution by the distribution of those ticks, Rhipicephalus appendiculata in Africa and Haemaphysalis intermedia in India. Animals bred in endemic areas do not normally develop disease, and the impact is therefore primarily on animals being moved for trade or breeding purposes. The disease caused by NSDV has similarities to several other ruminant diseases, and laboratory diagnosis is necessary for confirmation. There are published methods for diagnosis based on polymerase chain reaction, for virus growth in cell culture and for other simple diagnostic tests, though none has been commercialised. There is no established vaccine against NSDV, although cell-culture attenuated strains have been developed which show promise and could be put into field trials if it were deemed necessary. The virus is closely related to Crimean-Congo haemorrhagic fever virus, and studies on NSDV may therefore be useful in understanding this important human pathogen.

Full Text Available India was affected by a major outbreak of chikungunya fever caused by Chikungunya virus (CHIKV during 2006-2007. Kerala was the worst affected state during 2007 with a contribution of 55.8% suspected cases in the country. However, except for clinically reported case records, no systematic information is available on infection status of CHIKV in the region. Hence, we carried out a post-epidemic survey to estimate seroprevalence status [immunoglobulin G (IgG] in the community using commercially available indirect immunofluorescence test. This methodology had been reported to be highly specific and sensitive for CHIKV infection. The study area selected was the worst affected mid-highlands region of Kerala which harbour vast area of rubber plantations. The study evidenced 68% of the population to be seropositive for CHIKV IgG. Males were found more affected than females (χ2 = 9.86; p = 0.002. Among males, prevalence was significantly higher in the age classes 21-30 (χ2 = 5.46; p = 0.019 and 31-40 (χ2 = 5.84; p = 0.016 years. This may be due to high occupational risk of the male population engaged in plantation activities exposed to infective bites of Aedes albopictus. The current study provides an insight into the magnitude of CHIKV outbreak in Kerala.

Disease outbreak investigations were carried out in three states of Northern India namely Haryana (Rewari), Uttar Pradesh (Noida) and Delhi, where a total of 110 Indian peafowls (Pavo cristatus) showed sudden onset of nervous signs and died within a period of two weeks during June, 2012. The F (fusion) gene-based RT-PCR detection of Newcastle disease virus (NDV) in affected tissues confirmed the presence of the virus. Three NDV isolates were selected (one from each area under investigation) and further characterized. They were found to be of virulent pathotype (velogenic NDV) based on both pathogenicity assays (MDT, ICPI and IVPI) and partial F gene sequence analysis. Additionally, the phylogenetic analysis revealed that the isolates belonged to the genotype VIIi and XIII of class II avian Paramyxovirus serotype1 (APMV-1) and related closely to new emerging sub-genotypes. This is the first report regarding the presence of the fifth panzootic vNDV genotype VIIi from India. In this scenario, extensive epidemiological studies are suggested for surveillance of NDV genotypes in wild birds and poultry flocks of the country along with adopting suitable prevention and control measures.

Full Text Available Venereology-the study of venereal diseases or more recently, the sexually transmitted infections (STI includes a variety of pathogens namely viruses, bacteria, fungi and protozoa for which the common factor is the mode of transmission and acquisition: Sexual relations between human beings. Medical and other historians have often suggested that well-known diseases such as syphilis, gonorrhea, chancroid and lymphogranuloma venereum have existed since earliest times. However, it is difficult to identify modern disease entities based on written historical record. Studying the origin of STIs helps us to learn the political, economic and moral conditions that led to the disease. Effective management of STI rests on three pillars of diagnosis, prevention and treatment. For most of past 50 years in India, the diagnostic pillar has been the least well-supported. Until well into present century, diagnosis of STI in India was clinical. Treatment of STIs in India followed the methods used in England. Of course in the 19th century, in many parts of the world, only a few had access to modern methods of treatment; in India, there was extensive use of Ayurvedic treatment with traditional medicines. This article thus gives just an overview and evolution of venereology in India with regard to venereal diseases (now more often known as STIs/disease, control measures, academic, association and journal development and finally future perspective.

Full Text Available We report the isolation and complete genome sequencing of a new Mimiviridae family member, infecting Acanthamoeba castellanii, from sewage in Mumbai, India. The isolated virus has a particle size of about 435 nm and a 1,182,200-bp genome. A phylogeny based on the DNA polymerase sequence placed the isolate as a new member of the Mimiviridae family lineage A and was named as Mimivirus bombay. Extensive presence of Mimiviridae family members in different environmental niches, with remarkably similar genome size and genetic makeup, point towards an evolutionary advantage that needs to be further investigated. The complete genome sequence of Mimivirus bombay was deposited at GenBank/EMBL/DDBJ under the accession number KU761889.

During 2012-2014, mosaic disease on chayote in the farmers field of Kodaikanal region (high altitude zone) of Tamil Nadu was observed. The disease was characterized with severe mosaic, cupping and enation on leaves with reduced fruit size. Disease was found to causes an yield loss of more than 60% with the maximum disease incidence of 100% for the past 5 years consecutively. Preliminary serological and molecular screening indicated the association of begomovirus with the disease. Complete nucleotide sequence and phylogenetic analysis of DNA A revealed the identity of the virus as tomato leaf curl New Delhi virus (ToLCNDV). In recombination analysis study, the major parent was identified as ToLCNDV from Pakistan infecting tomato. Thus the present finding confirms expansion of new geographical region and host for ToLCNDV causing mosaic disease on chayote from Tamil Nadu. To our knowledge this is the first confirmed report for the occurrence of ToLCNDV on chayote in southern India.

For initial detection of Influenza viruses, amplification of matrix protein (M) gene of Inf-A and B viruses was carried out by real time RT-PCR. Influenza A positive viruses are then further subtyped with HA and NA gene specific primers. Sequencing and the phylogenetic analysis was performed for the H1N2 strain to understand its origin. The outcome of this full genome study revealed a unique reassortment event where the N-1289 virus acquired it's HA gene from a 2009 pandemic H1N1 virus with swine origin and the other genes from H3N2-like viruses of human origin. This study provides information on possibility of occurrence of reassortment events during influenza season when infectivity is high and two different subtypes of Inf-A viruses co-circulate in same geographical location.

Rice tungro disease, one of the major constraints to rice production in South and Southeast Asia, is caused by a combination of two viruses: Rice tungro spherical virus (RTSV) and Rice tungro bacilliform virus (RTBV). The present study was undertaken to determine the genetic variation of RTSV population present in tungro endemic states of Indian subcontinent. Phylogenetic analysis based on coat protein sequences showed distinct divergence of Indian RTSV isolates into two groups; one consisted isolates from Hyderabad (Andhra Pradesh), Cuttack (Orissa), and Puducherry and another from West Bengal, Coimbatore (Tamil Nadu), and Kanyakumari (Tamil Nadu). The results obtained from phylogenetic study were further supported with the SNPs (single nucleotide polymorphism), INDELs (insertion and deletion) and evolutionary distance analysis. In addition, sequence difference count matrix revealed 2-68 nucleotides differences among all the Indian RTSV isolates taken in this study. However, at the protein level these differences were not significant as revealed by Ka/Ks ratio calculation. Sequence identity at nucleotide and amino acid level was 92-100% and 97-100%, respectively, among Indian isolates of RTSV. Understanding of the population structure of RTSV from tungro endemic regions of India would potentially provide insights into the molecular diversification of this virus.

The genome of Cucumber mosaic virus New Delhi strain (CMV-ND) from India, obtained from tomato, was completely sequenced and compared with full genome sequences of 14 known CMV strains from subgroups I and II, for their genetic diversity. Sequence analysis suggests CMV-ND shares maximum sequence identity at the nucleotide level with a CMV strain from Taiwan. Among all 15 strains of CMV, the encoded protein 2b is least conserved, whereas the coat protein (CP) is most conserved. Sequence identity values and phylogram results indicate that CMV-ND belongs to subgroup I. Based on the recombination detection program result, it appears that CMV is prone to recombination, and different RNA components of CMV-ND have evolved differently. Recombinational analysis of all 15 CMV strains detected maximum recombination breakpoints in RNA2; CP showed the least recombination sites.

Bluetongue virus (BTV) infects all ruminants, including cattle, goats and camelids, causing bluetongue disease (BT) that is often severe in naïve deer and sheep. Reverse-transcription-loop-mediated-isothermal-amplification (RT-LAMP) assays were developed to detect eastern or western topotype of BTV strains circulating in India. Each assay uses four primers recognizing six distinct sequences of BTV genome-segment 1 (Seg-1). The eastern (e)RT-LAMP and western (w)RT-LAMP assay detected BTV RNA in all positive isolates that were tested (n=52, including Indian BTV-1, -2, -3, -5, -9, -10, -16, -21 -23, and -24 strains) with high specificity and efficiency. The analytical sensitivity of the RT-LAMP assays is comparable to real-time RT-PCR, but higher than conventional RT-PCR. The accelerated eRT-LAMP and wRT-LAMP assays generated detectable levels of amplified DNA, down to 0.216 fg of BTV RNA template or 108 fg of BTV RNA template within 60-90min respectively. The assays gave negative results with RNA from foot-and-mouth-disease virus (FMDV), peste des petits ruminants virus (PPRV), or DNA from Capripox viruses and Orf virus (n=10), all of which can cause clinical signs similar to BT. Both RT-LAMP assays did not show any cross-reaction among themselves. The assays are rapid, easy to perform, could be adapted as a 'penside' test making them suitable for 'front-line' diagnosis, helping to identify and contain field outbreaks of BTV.

To determine the prevalence and correlates of Herpes Simplex Virus-2 (HSV-2) and syphilis infections in the general population in India. 2456 adults were surveyed in Hyderabad, Bangalore and Chandigarh in India. Socio-demographic and lifestyle characteristics were obtained through a questionnaire, and a dried blood spot (DBS) was collected from all individuals aged 18 years and over; sexual behaviour was collected from those aged 18-49 years. DBS samples were tested for HSV-2 and syphilis serology. The association between HSV-2 and syphilis infections with socio-demographic and behavioural variables was analysed using multivariable logistic regression. The prevalence of HSV-2 and syphilis was 10.1% and 1.7%, respectively. Geographic differences in HSV-2 prevalence were significant, while for syphilis it was comparable. Urban-rural differences in prevalence were only seen for syphilis. For both infections, the prevalence between males and females was not significantly different. In males and females, HSV-2 prevalence increased significantly with increasing age; for syphilis, a slight trend was seen only in females. In a multivariable analysis, HSV-2 infection in males and females was associated with site, religion and testing positive for syphilis, in addition to reporting ≥ 2 lifetime partners in the previous year among males and being ever married or having had sex with a non-regular partner in the last year among females. The burden and geographic heterogeneity of HSV-2 and syphilis infections in India are significant. A national household and DBS-based sexually transmitted infection (STI) surveillance system would enable monitoring, especially in relation to the HIV epidemic, and planning of evidence-based prevention and treatment programmes.

Hepatitis B virus (HBV) and hepatitis C virus (HCV) are important transfusion-transmissible infections. This study was performed to assess the prevalence of HBV and HCV seropositivity among blood donors at a tertiary care hospital-based blood bank in India. The blood donation records over 5 years (2005-2009) were reviewed, retrospectively, for the prevalence and yearly trends of HBV and HCV seropositivity. A total of 94,716 donations were received. The overall number of HBV-seropositive donations was 1353 and that for HCV was 537, with the prevalence rates of 1.43% for hepatitis B surface antigen (HBsAg) and 0.57% for HCV. The seropositivity rate was higher in the replacement donors compared to the voluntary donors. The annual rates showed decreasing trends in case of HBsAg, but in case of HCV, there was a linear increase. Our study raises serious concerns regarding the HBV and HCV prevalence in our country. Although HBV showed decreasing trends, it cannot be relied upon because the donors were screened only for HBsAg. HCV is clearly on the rise. Stringent measures need to be taken on urgent basis including dissemination of information, strict screening of blood, inclusion of antibody to hepatitis B core antigen and other sensitive markers to the screening protocol, and better donor recruitment. © 2010 American Association of Blood Banks.

Aim: The aim of the study was to determine the overall prevalence of classical swine fever (CSF) in pigs in India, through a systematic review and meta-analysis of published data. Materials and Methods: Consortium for e-Resources in Agriculture, India, Google Scholar, PubMed, annual reports of All India Coordinated Research Project on Animal Disease Monitoring and Surveillance, and All India Animal Disease database of NIVEDI (NADRES) were used for searching and retrieval of CSF prevalence data (seroprevalence, virus antigen, and virus nucleic acid detection) in India using a search strategy combining keywords and related database-specific subject terms from January 2011 to December 2015 in English only. Results: A total of 22 data reports containing 6,158 samples size from 18 states of India were used for the quantitative synthesis, and overall 37% (95% confidence interval [CI]=0.24, 0.51) CSF prevalence in India was estimated. The data were classified into 4 different geographical zones of the country: 20% (95% CI=0.05, 0.55), 31% (95% CI=0.18, 0.47), 55% (95% CI=0.32, 0.76), and 34% (95% CI=0.14, 0.62). CSF prevalence was estimated in northern, eastern, western, and southern regions, respectively. Conclusion: This study indicates that overall prevalence of CSF in India is much lower than individual published reports. PMID:29657420

To compare the serology profile of donors from Hospital Cornea Retrieval Programme-donors (HCRP-D) and voluntary cornea donors (VC-D) from a large eye bank in Eastern India. This is a retrospective analysis of donor details from January 2011 to December 2016. Donor demographics, cause of death, and serology reports were compiled. Postmortem blood was tested for human immunodeficiency virus 1 and 2 (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis using government-approved kits as per the National Programme for Control of Blindness Standards of Eye Banking. Donors for whom serology was not possible were excluded. A total of 4300 of 4353 donors were included of which 74.3% were hospital donors and 25.7% were voluntary donors. A total of 93 (2.2%) donors with 94 seropositive reports were noted: 79 (84.9%) from HCRP-D and 14 (15.1%) from VC-D which was statistically significantly higher (P = 0.02). Among seropositive reports, HIV, HBV, HCV, and syphilis accounted for 12 (12.8%), 38 (40.4%), 36 (38.3%), and eight (8.5%), respectively. There was no correlation between the cause of death and seropositivity. A statistically significant decreasing trend in seroprevalence among hospital donors was observed over the years (5.3% in 2011 to 1.4% in 2016; P = 0.004). Two (0.47%) of 421 hospital donors with prior negative serology were found to be seropositive. Seropositive rates are significantly higher among hospital donors in spite of medical prescreening compared to nonscreened voluntary donors. Serology should be repeated even when prior reports are available.

Screening of undocumented migrants or refugees for hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infections has been offered free of charge and free from bureaucratic procedures since 2012 at four primary-level clinical centres in Naples and Caserta, Italy. Of 926 undocumented migrants and refugees visiting one of the primary-level clinical centres from January 2012 to June 2013, 882 (95%) were screened for hepatitis B surface antigen (HBsAg), total hepatitis B core antibody (anti-HBc) and antibodies against HCV and HIV. Of the 882 individuals enrolled, 78 (9%) were HBsAg positive, 35 (4%) anti-HCV positive and 11 (1%) anti-HIV positive (single infections); seven (1%) had more than one infection (three were HBsAg positive). Of the 801 HBsAg-negative patients, 373 (47%) were anti-HBc positive. The HBsAg-positivity rate was high (14%; 62/444) in individuals from sub-Saharan Africa and intermediate in those from eastern Europe (6%; 12/198), northern Africa (2%; 2/80) and Bangladesh, India, Pakistan and Sri Lanka (the 'India-Pakistan area') (3%; 4/126). Anti-HCV was detected in 9/126 (7%) individuals originating from the India-Pakistan area, in 12/198 (6%) from eastern Europe, in 17/444 (4%) from sub-Saharan and in 2/80 (2%) from northern Africa. The HBV, HCV and HIV infections in the undocumented migrants and refugees screened serve as a reminder to the Italian healthcare authorities to carry out extensive screening and educational programmes for these populations.

Full Text Available The Zika virus has been in the news for quite some time due to the ongoing recent outbreak in the Southern America, which started in December 2015. It has been declared a public health emergency by the World Health Organization in February 2016 owing to its association with the congenital deformities, particularly microcephaly in infants borne to the infected mothers. The rapid spread of the virus throughout the United States of America and subsequently to Asia has raised serious international concerns. Its spread to countries neighboring India is a serious threat to the Indian population. This review article gives an overview about the virus, its diagnosis, clinical features, and the management.

Measles, mumps and rubella are vaccine preventable diseases. However, morbidity and mortality due to these diseases remain largely unnoticed in India. Measles has received much attention; mumps and rubella still need to garner attention. According to the World Health Organization, near-elimination of mumps could be achieved by maintaining high vaccine coverage using a two-dose strategy. However, Government of India has not yet decided on mumps vaccine. In this review, we have reviewed sero-prevalence studies, vaccine studies, outbreak investigations, virus isolation and virus genotyping studies on mumps. Overall, mumps seems to be a significant public health problem in India, but does not garner attention due to the absence of a surveillance and documentation system. Thus, inclusion of mumps antigen in the Universal immunization program would have added advantages, the economic burden imposed by the cost of the vaccine offset by a reduction in disease burden.

Indian garlic is infected with Onion yellow dwarf virus (OYDV), Shallot latent virus (SLV), Garlic common latent virus (GarCLV) and allexiviruses. Identity and distribution of garlic viruses in various garlic accessions from different geographical regions of India were investigated. OYDV and allexiviruses were observed in all the garlic accessions, while SLV and GarCLV were observed only in a few accessions. A multiplex reverse transcription (RT)-PCR method was developed for the simultaneous detection and identification of OYDV, SLV, GarCLV and Allexivirus infecting garlic accessions in India. This multiplex protocol standardized in this study will be useful in indexing of garlic viruses and production of virus free seed material. Copyright © 2014 Elsevier B.V. All rights reserved.

Full Text Available Abstract Partly due to climate change, and partly due to changes of human habitat occupation, the impact of tick-borne viruses is increasing. Nairobi sheep disease virus (NSDV and Ganjam virus (GV are two names for the same virus, which causes disease in sheep and goats and is currently known to be circulating in India and East Africa. The virus is transmitted by ixodid ticks and causes a severe hemorrhagic disease. We have developed a real-time PCR assay for the virus genome and validated it in a pilot study of the pathogenicity induced by two different isolates of NSDV/GV. One isolate was highly adapted to tissue culture, grew in most cell lines tested, and was essentially apathogenic in sheep. The second isolate appeared to be poorly adapted to cell culture and retained pathogenicity in sheep. The real-time PCR assay for virus easily detected 4 copies or less of the viral genome, and allowed a quantitative measure of the virus in whole blood. Measurement of the changes in cytokine mRNAs showed similar changes to those observed in humans infected by the closely related virus Crimean Congo hemorrhagic fever virus.

Full Text Available India continues to wage a battle against the human immunodeficiency virus (HIV/acquired immune deficiency syndrome (AIDS epidemic. Despite an array of preventive and control efforts directed against the disease, it continues to finds its way from the high risk groups to the general population. Women are more vulnerable to HIV/AIDS because of biological as well as socio-cultural factors. Microbicides appear to provide an attractive option as a means of protection to be used by women. At present, microbicide trials are in study phases I and II in India. The development of an ideal microbicide candidate which would be effective and confirms to user satisfaction poses a major challenge to researchers.

Singh, Vinod Kumar; Rajak, Kaushal Kishore; Kumar, Amit; Yadav, Sharad Kumar

2018-05-04

Classical swine fever (CSF) is a globally significant disease of swine caused by classical swine fever virus. The virus affects the wild boars and pigs of all age groups, leading to acute, chronic, late-onset or in-apparent course of the disease. The disease causes great economic loss to the piggery industry due to mortality, stunted growth, poor reproductive performance, and by impeding the international trade of pig and pig products. In India, CSF outbreaks are reported from most of the states wherever pig rearing is practiced and more frequently from northeast states. In spite of the highly devastating nature and frequent outbreaks, CSF remained underestimated and neglected for decades in India. The country requires rapid and sensitive diagnostic tests for an early detection of infection to limit the spread of the disease. Also, effective prophylactics are required to help in control and eradication of the disease for the development of the piggery industry. This review looks into the economic impact; epidemiology of CSF highlighting the temporal and spatial occurrence of outbreaks in the last two decades, circulation, and emergence of the virus genotypes in and around the country; and the constraints in the disease control, with the aim to update the knowledge of current status of the disease in India. The article also emphasizes the importance of the disease and the need to develop rapid specific diagnostics and effective measures to eradicate the disease.

Full Text Available Equine influenza is a contagious viral disease that affects all members of the family Equidae, i.e. horses, donkeys and mules. The authors describe the pattern of equine influenza outbreaks in a number of states of India from July 2008 to June 2009. The disease was first reported in June 2008 in Katra (Jammu and Kashmir and spread to ten other states within a year. All outbreaks of equine influenza in the various states were confirmed by laboratory investigations (virus isolation and/or serological confirmation based on haemagglutination inhibition [HI] assays of paired samples before declaring them as equine influenza virus-affected state(s. The virus (H3N8 was reported from various locations in the country including Katra, Mysore (Karnataka, Ahmedabad (Gujarat, Gopeshwar and Uttarkashi (Uttarakhand and was isolated in 9- to 11-day-old embryonated chicken eggs. The virus was confirmed as H3N8 by HI assays with standard serum and amplification of full-length haemagglutinin and neuraminidase genes by reverse transcriptase-polymerase chain reaction. Serum samples (n = 4 740 of equines from 13 states in India screened by HI revealed 1 074 (22.65% samples as being positive for antibodies to equine influenza virus (H3N8.

During a survey in June 2011, severe leaf yellow mosaic disease was observed on about 45 % plants of Jatropha curcas growing in the Katerniaghat wildlife sanctuary in India. An association of a begomovirus with disease was detected in 15 out of 20 samples by PCR using begomovirus genus-specific primers and total DNA isolated from symptomatic leaf samples. For identification of the begomovirus, the complete genome was amplified using a Phi-29 DNA-polymerase-based rolling-circle amplification kit and total DNA from five representative samples and then digested with BamHI. The linearized RCA products were cloned and sequenced. Their GenBank accession numbers are JN698954 (SKRK1) and JN135236 (SKRK2). The sequences of the two begomovirus isolates were 97 % identical to each other and no more than 86 % to those of jatropha mosaic India virus (JMIV, HM230683) and other begomoviruses reported worldwide. In phylogenetic analysis, SKRK1 and SKRK2 clustered together and showed distant relationships to jatropha mosaic India virus, Jatropha curcas mosaic virus, Indian cassava mosaic virus, Sri Lankan cassava mosaic virus and other begomoviruses. Based on 86 % sequence identities and distant phylogenetic relationships to JMIV and other begomoviruses and the begomovirus species demarcation criteria of the ICTV (curcas were identified as members of a new begomovirus species and provisionally designated as jatropha leaf yellow mosaic Katerniaghat virus (JLYMKV). Agroinfectious clones of the DNA molecule of the begomovirus isolate were also generated, and the fulfillment of Koch's postulates was demonstrated in J. curcas plants.

Phlebotomine sandflies are implicated as vectors due to their predominance in endemic areas, repeated virus isolations and their ability to transmit the virus by transovarial and venereal routes. Significant contributions have been made in the development of diagnostics and prophylactics, vaccines and antivirals. Two candidate vaccines, viz. a recombinant vaccine and a killed vaccine and siRNAs targeting P and M proteins have been developed and are awaiting clinical trials. Rhabdomyosarcoma and Phlebotomus papatasi cell lines as well as embryonated chicken eggs have been found useful in virus isolation and propagation. Despite these advancements, CHPV has been a major concern in Central India and warrants immediate attention from virologists, neurologists, paediatricians and the government for containing the virus.

Foot-and-mouth disease (FMD) is a contagious disease of cloven-hoofed animals that causes substantial and perpetual economic loss. Apart from the contagious nature of the disease, the FMD virus can establish in a "carrier state" among all cloven-hoofed animals. The Mithun (Bos frontalis), popularly called the "Cattle of Mountain," is found in the geographically isolated, hilly region of north-east India: Arunachal Pradesh, Nagaland, Manipur and Mizoram. Despite the geographical inaccessibility, infection by FMD virus has emerged as the single most devastating disease among Mithun after the eradication of rinderpest from this region. Samples from outbreaks of FMD in Mithun were analysed by sandwich ELISA, multiplex RT-PCR (MRT-PCR) and liquid-phase blocking enzyme-linked immunosorbent assay and isolated in the BHK-21 cell line. The results indicate the presence of FMDV serotype "O." The sequencing and molecular phylogenies have revealed close relationships in the lineage of type "O" isolates from Bangladesh. The findings will provide useful information for further research and development of a sustainable programme for the progressive control of FMD in the Mithun population. © 2017 Blackwell Verlag GmbH.

In many parts of Asia measles virus (MV) continues to be endemic. However, little is known about the genetic characteristics of viruses circulating on this continent. This study reports the molecular epidemiological analysis based on the entire nucleocapsid (N) and hemagglutinin (H) genes of the first isolates from Nepal and Taiwan, as well as of recent MV strains from India, Indonesia, and China. Four isolates collected in various regions in Nepal during 1999 belonged to a new genotype, tentatively called D8. Another Nepalese isolate and one from India belonged to genotype D4. The diversity of the Nepalese strains indicated that measles continues to be endemic in this country. The isolate from Taiwan grouped with D3 viruses and one Chinese strain isolated in The Netherlands was assigned to the previously described clade H, known to be endemic in Mainland China. Molecular characterization emerges as an important tool for monitoring virus endemicity and vaccination efforts.

Foot-and-mouth disease (FMD) virus serotype O is the most common cause of FMD outbreaks in India and three of the six lineages that have been described are most frequently detected, namely Ind2001, PanAsia and PanAsia 2. We report the full capsid sequence of 21 serotype O viruses isolated from India between 2002 and 2012. All these viruses belong to the Middle East-South Asia (ME-SA) topotype. The serological cross-reactivity of a bovine post-vaccination serum pool raised against the current Indian vaccine strain, O/IND/R2/75,was tested by virus neutralisation test with the 23 Indian field isolates, revealing a good match between the vaccine and the field isolates. The cross reactivity of the O/IND/R2/75 vaccine with 19 field isolates from other countries (mainly from Asia and Africa) revealed a good match to 79% of the viruses indicating that the vaccine strain is broadly cross-reactive and could be used to control FMD in other countries. Comparison of the capsid sequences of the serologically non-matching isolates with the vaccine strain sequence identified substitutions in neutralising antigenic sites 1 and 2, which could explain the observed serological differences.

Reduced seed production in onion is associated with Onion yellow dwarf virus (OYDV), a filamentous Potyvirus. Onion is also infected with other filamentous virus particles suspected to be Allexivirus. RT-PCR was used to detect mixed infection of both the viruses in leaves and bulbs. A duplex RT-PCR was developed, which simultaneously detected the presence of these two viruses in winter (Rabi) onion bulb. In summer (Kharif) onion bulbs only Allexivirus was detected. The absence of OYDV in summer crop is discussed. The sequencing of RT-PCR amplified products confirmed the identity of OYDV and Allexivirus, the latter showing closer identity to Garlic virus C (GVC)/Garlic mite-borne mosaic virus. This makes the first detection of an Allexivirus in onion crop in India. The duplex RT-PCR to detect these viruses (OYDV and Allexivirus) would be an improvement for indexing of viruses in onion bulbs for seed production.

Full Text Available Background Dengue is a global human public health threat, causing severe morbidity and mortality. The occurrence of sequential infection by more than one serotype of dengue virus (DENV is a major contributing factor for the induction of Dengue Hemorrhagic Fever (DHF and Dengue Shock Syndrome (DSS, two major medical conditions caused by DENV infection. However, there is no specific drug or vaccine available against dengue infection. There are reports indicating the increased incidence of concurrent infection of dengue in several tropical and subtropical regions. Recently, increasing number of DHF and DSS cases were reported in India indicating potential enhancement of concurrent DENV infections. Therefore, accurate determination of the occurrence of DENV serotype co-infections needs to be conducted in various DENV prone parts of India. In this context, the present study was conducted to analyse the magnitude of concurrent infection in northern Kerala, a southwest state of India, during three consecutive years from 2013 to 2015. Methods A total of 120 serum samples were collected from the suspected dengue patients. The serum samples were diagnosed for the presence of dengue NS1 antigen followed by the isolation of dengue genome from NS1 positive samples. The isolated dengue genome was further subjected to RTPCR based molecular serotyping. The phylogenetic tree was constructed based on the sequence of PCR amplified products. Results Out of the total number of samples collected, 100 samples were positive for dengue specific antigen (NS1 and 26 of them contained the dengue genome. The RTPCR based molecular serotyping of the dengue genome revealed the presence of all four serotypes with different combinations. However, serotypes 1 and 3 were predominant combinations of concurrent infection. Interestingly, there were two samples with all four serotypes concurrently infected in 2013. Discussion All samples containing dengue genome showed the presence of

Genetic characterization of natural variants of Vpu from HIV-1 infected individuals from Northern India and their impact on virus release and cell death.

Directory of Open Access Journals (Sweden)

Sachin Verma

Full Text Available BACKGROUND: Genetic studies reveal that vpu is one of the most variable regions in HIV-1 genome. Functional studies have been carried out mostly with Vpu derived from laboratory adapted subtype B pNL 4-3 virus. The rationale of this study was to characterize genetic variations that are present in the vpu gene from HIV-1 infected individuals from North-India (Punjab/Haryana and determine their functional relevance. METHODS: Functionally intact vpu gene variants were PCR amplified from genomic DNA of HIV-1 infected individuals. These variants were then subjected to genetic analysis and unique representative variants were cloned under CMV promoter containing expression vector as well as into pNL 4-3 HIV-1 virus for intracellular expression studies. These variants were characterized with respect to their ability to promote virus release as well as cell death. RESULTS: Based on phylogenetic analysis and extensive polymorphisms with respect to consensus Vpu B and C, we were able to arbitrarily assign variants into two major groups (B and C. The group B variants always showed significantly higher virus release activity and exhibited moderate levels of cell death. On the other hand, group C variants displayed lower virus release activity but greater cell death potential. Interestingly, Vpu variants with a natural S61A mutation showed greater intracellular stability. These variants also exhibited significant reduction in their intracellular ubiquitination and caused greater virus release. Another group C variant that possessed a non-functional β-TrcP binding motif due to two critical serine residues (S52 and S56 being substituted with isoleucine residues, showed reduced virus release activity but modest cytotoxic activity. CONCLUSIONS: The natural variations exhibited by our Vpu variants involve extensive polymorphism characterized by substitution and deletions that contribute toward positive selection. We identified two major groups and an extremely

We characterized influenza A(H1N1)pdm09 isolates from large-scale outbreaks that occurred in Nepal and India in early 2015. Although no specific viral features, which may have caused the outbreaks, were identified, an S84N substitution in hemagglutinin was frequently observed. Chronological phylogenetic analysis revealed that these Nepalese and Indian viruses possessing the S84N substitution constitute potential ancestors of the novel genetic subclade 6B.1 virus that spread globally in the following (2015/16) influenza season. Thus, active surveillance of circulating influenza viruses in the Southern Asia region, including Nepal and India, would be beneficial for detecting novel variant viruses prior to their worldwide spread. © 2017 The Authors.

We have studied the clinical characteristics, severity and seasonality of rotavirus infection and prevalent genotypes in 652 non-rota vaccinated children in Odisha in eastern India. P genotypes were analysed for their association with host blood group antigens. P type of the virus is determined by the VP8* gene, and specific recognition of A - type of Histo - blood group antigen by P[14]VP8* has been reported. VP4, VP7 and VP6 genes of commonly identified G1P[8] strain were compared with genes of the same strain isolated from other parts of India, elsewhere and strains used for Rotarix and Rotateq vaccines. In 54.75% of children with gastroenteritis, rota virus was found. 9.65% of children had moderate, 78.07% severe, and 12.28% very severe disease as assessed using the Vesikari scoring system. The incidence of infection was highest during winter months. There was no association between any blood group and specific P genotypes. G1P[8] was the commonest cause of gastroenteritis, followed by G1P[11], G3P[8], G9P[8], G2P[4], G2P[6], G9P[4], G9P[11] and G1P[6]. Predominant G genotypes identified were G1 (72.9%), G9 (10.81%), G2 (8.10%) and G3 (8.10%). Sequence analysis of the VP7 gene, placed the G1P[8] strain in lineage 1 and of VP6 gene placed nine G1P[8] strains in subgroup II and one in subgroup I. The VP7 gene segment of two Odisha G1P[8] strains were found to cluster relatively close to the VP7 sequences of Rotarix vaccine. Antigenic differences were found with vaccine strains. Ten G1P[8] strains sequenced for the VP4 gene had 91-93% nucleotide and 92-96% amino acid identity with Rotateq vaccine P[8]). Rotarix vaccine VP4 had 89-91% nucleotide and 90-92% amino acid identity. Our findings indicate genetic variability of rotavirus strains circulating in the region and are significant, given the introduction of rota vaccination in the State. Copyright © 2017 Elsevier B.V.

The present study was carried out to monitor influenza viruses by identifying the virus and studying the seasonal variation during 2007-2009 in Mumbai. A total of 193 clinical respiratory samples (nasal and throat swab) were collected from patients having influenza like illness in Mumbai region. One-step real-time reverse-transcriptase PCR (rRTPCR) was used to detect Influenza type A (H1 and H3) and Influenza type B virus. Isolation of the virus was carried out using in vitro system which was further confirmed and typed by hemagglutination assay and hemagglutination inhibition assay. Out of 193 samples 24 (12.4 3%) samples tested positive for influenza virus, of which 13 (6.73 %) were influenza type A virus and 10 (5.18 %) were influenza type B virus, while 1 sample (0.51 %) was positive for both. By culture methods, 3 (1.55 %) viral isolates were obtained. All the three isolates were found to be Influenza type B/Malaysia (Victoria lineage) by Hemagglutination Inhibition Assay. The data generated from the present study reveals that both Influenza type A and B are prevalent in Mumbai with considerable activity. The peak activity was observed during monsoon season.

This study systematically reviews the existing literature on sexually transmitted infections (STIs) including human immunodeficiency virus (HIV) infection in the men who have sex with men (MSM) in India. After a comprehensive literature search of Medline (1950-June 2008), Embase (1980-June 2008), and the Cochrane Library (1950-June 2008), 12 published studies met the inclusion criteria. The link between sexual identity and sexual behavior is a complex phenomenon strongly embedded in a very specific context in India. MSM in India are an important risk group for acquiring STIs/HIV and effective culturally sensitive prevention programs should be designed for them. The combined estimate of HIV prevalence in the MSM population in India calculated from 5 included studies was 16.5% (95% confidence intervals: 11% to 22%). The review also identifies the lacunae in existing literature and provides future directions for research in the MSM community in India.

Full Text Available Introduction: Nasopharyngeal carcinoma (NPC is a common cancer in the North-East region of India. Though the role of environmental contributors of NPC in the North-Eastern part of India is firmly established, EBV as an etiological agent in the region remains unexplored. Material and Methods: Fifty-one patients, who presented at the department of ENT, NEIGRIHMS and were confirmed as NPC upon histopathological examination, were included in the study. Chromogenic in-situ hybridization (CISH was used for the evaluation of EBER (Epstein Barr Virus Encoded RNA. Presence of nuclear signals was taken as positive for EBER expression. EBER status was correlated with various clinicopathological parameters like age, sex, dietary habits, histological types of NPC, and ethnicity of the patients. Results: The age range of the study group was 25 to 70 years with a mean age of 44.64 years and a male:female ratio of 3:2. Non-keratinizing undifferentiated type of NPC was the most common histological type. EBV was positive in 59% (30/51 of our cases. It showed a statistically significant correlation with the Naga community (P=0.01, with consumption of smoked food (P=0.02, and cigarette smoking (P=0.02. There was no correlation of EBV with age, sex, lymph node metastasis, stage, and histology. Conclusion: Our result indicates that EBV may be an additional risk factor in the pathogenesis of NPC in this region of India. So apart from lifestyle modification, a future study for a screening test for EBV viral load even in asymptomatic patients may be considered, for determination of disease susceptibility, early diagnosis, and proper management.

Full Text Available Acute Encephalitis Syndrome (AES is a major seasonal public health problem in Bihar, India. Despite efforts of the Bihar health department and the Government of India, burden and mortality of AES cases have not decreased, and definitive etiologies for the illness have yet to be identified.The present study was undertaken to study the specific etiology of AES in Bihar.Cerebrospinal fluid and/or serum samples from AES patients were collected and tested for various pathogens, including viruses and bacteria by ELISA and/or Real Time PCR.Of 540 enrolled patients, 33.3% (180 tested positive for at least one pathogen of which 23.3% were co-positive for more than one pathogen. Most samples were positive for scrub typhus IgM or PCR (25%, followed by IgM positivity for JEV (8.1%, WNV (6.8%, DV (6.1%, and ChikV (4.5%.M. tuberculosis and S. pneumoniae each was detected in ~ 1% cases. H. influenzae, adenovirus, Herpes Simplex Virus -1, enterovirus, and measles virus, each was detected occasionally. The presence of Scrub typhus was confirmed by PCR and sequencing. Bihar strains resembled Gilliam-like strains from Thailand, Combodia and Vietnam.The highlights of this pilot AES study were detection of an infectious etiology in one third of the AES cases, multiple etiologies, and emergence of O. tsutsugamushi infection as an important causative agent of AES in India.

Isolates of poxviruses were made from thirteen of eighteen specimens of scabs taken from pox lesions on buffaloes in five different districts of Maharashtra State, India, between December, 1985 and February, 1987. The biological characters of twelve of the isolates resembled those of the Hissar strain of buffalopox virus; the thirteenth isolate appeared to be vaccinia. The Hin dIII restriction profiles of DNA from all 13 isolates and from the Hissar strain were typical of those given by vaccinia strains. DNA from all twelve Maharashtra buffalopox (BPV) isolates gave identical profiles with each of three additional endonucleases; these viruses appear to be repeated isolations of a single strain of BPV. The DNA profile of this strain was not the same as that of the Hissar strain of BPV and both could readily be distinguished from each of the three strains of vaccinia virus which had been used in India. The thirteenth Maharashtra isolate was indistinguishable from vaccinia in its biological properties, but the restriction profile of its DNA differed from those of three vaccinia strains and the BPV isolates. These observations, made 6-8 years after cessation of smallpox vaccination indicate that BPV is an emerging enzootic virus and is a subspecies of vaccinia virus.

Full Text Available Introduction: Tuberculosis and Human Immunodeficiency Virus (HIV co infection is becoming one of the most important public health issues in India. In some developing countries, 40% of all tuberculosis cases are attributed to HIV infection and in more than 50% of cases, tuberculosis is the first manifestation of HIV infection. Materials and methods: A cross sectional study was done among the in-patients of a tuberculosis ward in a tertiary care hospital in Eastern India. Fifty patients with HIV and tuberculosis infection of an extra pulmonary site, were included in the study. Results: A vast majority of the participants were young males. More than 80% were using intoxicants like alcohol or tobacco, 76% admitted exposure to commercial sex workers and 12% were intravenous drug users. Twenty five (50% of the participants had disseminated tuberculosis, that is tubercular infection of more than one anatomical site. Maximum (62% participants had tubercular infection of lymph nodes, followed by pleura, abdomen and central nervous system. Discussion and conclusions: The socio-demographic correlates of participants were similar to that seen in similar studies in other parts of the world. But in our study, tubercular lymphadenitis was the most common extra-pulmonary manifestation and proportion of disseminated tuberculosis cases was as high as 50%. Both these findings are different from studies from other parts of the world. These findings warrant a larger research study and programmatic changes to address issues of HIV/TB co infection.

Biological characterization and variability of the nucleocapsid protein gene of Groundnut bud necrosis virus isolates infecting pea from India

Full Text Available A disease of pea characterized by browning in veins, leaves and stems, mostly in growing tips, and brown circular spots on pods, was recorded in four districts of Uttar Pradesh, India. The causal agent of this disease was detected by reverse transcription-polymerase chain reaction (RT-PCR using primers pair HRP 26/HRP 28 and identified as Groundnut bud necrosis virus (GBNV on the basis of nucleocapsid protein (NP gene sequence. Virus isolates from Bareilly (BRY, Kanpur (KNP, Udham Singh Nagar (USN and Shahjahanpur (SJP were designated as GBNV-[Pea_BRY], GBNV-[Pea_KNP], GBNV-[Pea_USN] and GBNV-[Pea_SJP] and their NP genes sequenced. The sequence data of each isolate were deposited at NCBI database (JF281101-JF281104. The complete nucleotide sequence of the NP genes of all the GBNV isolates had a single open reading frame of 831 nucleotides and 276 amino acids. The isolates had among them 2% variability at amino acid level and 2‒3 variability at nucleotide level, but had variability with other GBNV isolates of fabaceous hosts in the range of 0‒6% at amino acid level and 1‒8% at nucleotide level. Though this variation in nucleotide sequences of GBNV isolates from fabaceous hosts is within the limits of species demarcation for tospoviruses, formation of a separate cluster within the GBNV isolates indicates the possibility of distinct variants in GBNV.

2017-06-01

Chikungunya virus (CHIKV) is a mosquito-borne alphavirus which presents with symptoms of fever, rash, arthralgia, and occasional neurologic disease. While outbreaks have been earlier reported from India and other parts of the world, the recent outbreak in India witnessed more than 1000 cases. Various systemic and rarely neurological complications have been reported with CHIKV. We report two cases of Guillain-Barré syndrome (GBS) with CHIKV. GBS is a rare neurological complication which may occur after subsidence of fever and constitutional symptoms by several neurotropic viruses. We describe two cases of severe GBS which presented with rapidly progressive flaccid quadriparesis progressing to difficulty in swallowing and breathing. Both required mechanical ventilation and improved partly with plasmapharesis. The cases emphasize on (1) description of the rare complication in a setting of outbreak with CHIKV, (2) acute axonal as well as demyelinating neuropathy may occur with CHIKV, (3) accurate identification of this entity during outbreaks with dengue, both of which are vector borne and may present with similar complications.

AIM: To determine the prevalence of hepatitis B and C virus infections in human immunodeficiency virus (HIV) -positive patients at a tertiary care hospital in New Delhi, India. METHODS: Serum samples from 451 HIV positive patients were analyzed for HBsAg and HCV antibodies during three years (Jan 2003-Dec 2005). The control group comprised of apparently healthy bone-marrow and renal donors. RESULTS: The study population comprised essentially of heterosexually transmitted HIV infection. The prevalence rate of HBsAg in this population was 5.3% as compared to 1.4% in apparently healthy donors (P < 0.001). Though prevalence of HCV co-infection (2.43%) was lower than HBV in this group of HIV positive patients, the prevalence was significantly higher (P < 0.05) than controls (0.7%). Triple infection of HIV, HBV and HCV was not detected in any patient. CONCLUSION: Our study shows a significantly high prevalence of hepatitis virus infections in HIV infected patients. Hepatitis viruses in HIV may lead to faster progression to liver cirrhosis and a higher risk of antiretroviral therapy induced hepatotoxicity. Therefore, it would be advisable to detect hepatitis virus co-infections in these patients at the earliest. PMID:17106941

Enteric virus removal from water by coal-based sorbents: development of low-cost water filters

Chaudhuri, M.; Sattar, S.A.

1986-01-01

Using poliovirus type 1 (Sabin) and dechlorinated tap water, several coal-based sorbents were tested for their capacity to remove viruses from water. The sorbents included bituminous coal from Giridih, India, pretreated/impregnated with either alum, ferric hydroxide, lime or manganese dioxide. Filtrasorb-400, commercially available active carbon, was used as a reference. In batch tests, with input virus concentration of 2.34-2.83x10/sup 6/ PFU/1 and sorbent concentration of 10 g/l, alum pretreated coal removed about 96% of the virus when pH of the water was between 6.3 and 8.9. Virus sorption was rapid and a plateau was reached in 30 min. Compared with the active carbon, alum pretreated coal exhibited greater sorption energy and about one log higher limiting poliovirus sorption capacity. Downflow column study indicated the potential of alum pretreated coal as a filter media for removing enteric viruses from water. A previous study showed this sorbent to be capable of removing enteric bacteria as well. Water filters prepared from such low-cost material may prove useful for domestic use in rural areas of India and other developing countries. 19 refs.

With a population of 1.1 billion, India is considered to be a country in which effective prevention interventions could contain the development of a human immunodeficiency virus (HIV) epidemic. Heterosexual transmission accounts for 85 % of the extant HIV infections. This study sought to assess the feasibility of conducting a group, culturally tailored behavioral intervention and its impact on sexual barrier use, self-efficacy, knowledge, conflict resolution, and coping among high-risk heterosexual couples in Northern India. This pilot study was conducted at the Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India from February 2008 to January 2009. Thirty sexually active high-risk couples were drawn from a convenience sample of PGIMER patients attending infectious disease and family planning clinics. Couples participated in 1 month of three weekly gender-concordant behavioral intervention groups and were individually administered assessments preintervention and post-intervention. The intervention was tailored to the Northern Indian context and addressed sexual barrier use, human immunodeficiency virus (HIV)/sexually transmitted infection transmission, and cognitive behavioral skill building focusing on sexual negotiation and communication. The participants had a mean age of 32 years (men) and 29 years (women), and the majority had at least 10 years of education. At baseline, the majority reported inconsistent condom use (knowledge, and women increased their use of positive coping tactics. The results highlight the potential to successfully utilize a group intervention to discuss sensitive issues such as sexual risk behavior among both men and women. Strategies to improve condom use and communication without increasing intimate partner violence in high-risk couples may be an important adjunct to preventing the development of a generalized epidemic in India.

Multifactorial causation, potential for prevention, and the sheer threat it poses make cervical cancer an important disease for in-depth studies, as has been attempted by this paper. This paper attempts to review the available knowledge regarding the epidemiology and pattern of cervical cancer; types of HPV (human papilloma virus prevalent among cervical cancer patients and among women in general, high-risk groups such as commercial sex workers, and HIV (human immunodeficiency virus-positive women; and the role of the national program on cancer in control efforts. The peak age of incidence of cervical cancer is 55–59 years, and a considerable proportion of women report in the late stages of disease. Specific types of oncogenic HPV-16, 18 have been identified in patients with cervical cancer. Other epidemiological risk factors are early age at marriage, multiple sexual partners, multiple pregnancies, poor genital hygiene, malnutrition, use of oral contraceptives, and lack of awareness. A multipronged approach is necessary which can target areas of high prevalence identified by registries with a combination of behavior change communication exercises and routine early screening with VIA. Sensitizing the people of the area, including menfolk, is necessary to increase uptake levels. Vaccination against types 16 and 18 can also be undertaken after taking into confidence all stakeholders, including the parents of adolescent girls. Preventing and treating cervical cancer and reducing the burden are possible by targeting resources to the areas with high prevalence.

Full text: Okra, an important vegetable of the tropics and sub-tropics is very popular in India. Its production is limited by 'yellow vein mosaic virus'. Advances in breeding for resistance to this virus have been made through inter-specific hybridisation as well as mutagenesis. Hybridisation used A. manihot ssp. manihot and ssp. tetraphyllus. New varieties showed 87-146% yield increases over older virus susceptible varieties. The number of fruits increased by 13-30%, virus incidence decreased by 84-99%. An EMS induced mutant 'EMS8' showed a yield increase of 107%, a fruit number increase of 16% and a disease decrease of 99%. The mutant also carries a good amount of resistance to the fruit borer; infestation decreased by 46%. The mutant is the best among the tested varieties for canning, is suitable for dehydration, and can be stored prepacked at room temperature for 6 days. (author)

In the last few decades through an awareness of transfusion transmitted infections (TTI), a majority of countries have mandated serology based blood screening assays for Human immunodeficiency virus (HIV), Hepatitis C virus (HCV), and Hepatitis B virus (HBV). However, despite improved serology assays, the transfusion transmission of HIV, HCV, and HBV continues, primarily due to release of serology negative units that are infectious because of the window period (WP) and occult HBV infections (OBI). Effective mode of nucleic acid technology (NAT) testing of the viruses can be used to minimize the risk of TTIs. This review compiles the examples of NAT testing failures for all three viruses; analyzes the causes for failure, and the suggestions from retrospective studies to minimize such failures. The results suggest the safest path to be individual donation testing (ID) format for highest sensitivity, and detection of multiple regions for rapidly mutating and recombining viruses. The role of blood screening in the context of the donation and transfusion practices in India, the donor population, and the epidemiology is also discussed. World wide, as the public awareness of TTIs increases, as the recipient rights for safe blood are legally upheld, as the possibility to manage diseases such as hepatitis through expensive and prolonged treatment becomes accessible, and the societal responsibility to shoulder the health costs as in the case for HIV becomes routine, there is much to gain by preventing infections than treating diseases.

Dengue virus (DENV) causes a wide range of diseases in humans, from acute febrile illness Dengue fever (DF) to life-threatening Dengue hemorrhagic fever (DHF) or Dengue shock syndrome (DSS). Factors believed to be responsible for spread of Dengue virus infection include explosive population growth, unplanned urban overpopulation with inadequate public health systems, poor standing water and vector control, climate changes and increased international recreational, business, military travel to endemic areas. All of these factors must be addressed to control the spread of Dengue and other mosquito-borne infections. The detection of Dengue virus RNA by reverse transcriptase PCR (RT-PCR) in human serum or plasma samples is highly indicative of acute Dengue fever. Moreover, the method is able to identify the Dengue virus serotype by demonstrating defined sequence homologies in the viral genomic RNA. During the nine year period of this study analysis, 6767 strongly suspected cases were tested by RT-PCR. 1685 (24.9%) were Dengue PCR positive and confirmed as Dengue cases. Observations on the seasonality were based on the nine year's data as the intensity of sampling was at its maximum during monsoon season. Dengue typing was done on 100 positive samples after storage of Dengue RNA at - 80°C. Dengue serotypes were detected in 69 samples of which Dengue 2 was most predominant. 576 samples were processed for NS1 antigen and PCR simultaneously. 19/576 were positive (3.3 %) for NS1 as well as by PCR. 23/576 samples were negative for NS1 antigen, but were positive by RT-PCR. The remaining 534 samples which were negative for NS1 antigen were also negative by Dengue RT-PCR. In this study we sought to standardize rapid, sensitive, and specific fluorogenic probe-based RT-PCR assay to screen and serotype a representative range of Dengue viruses that are found in and around Mumbai. Qualitative Dengue virus TaqMan assays could have tremendous utility for the epidemiological

Variability of Emaravirus Species Associated with Sterility Mosaic Disease of Pigeonpea in India Provides Evidence of Segment Reassortment

2017-01-01

Sterility mosaic disease (SMD) of pigeonpea is a serious constraint for cultivation of pigeonpea in India and other South Asian countries. SMD of pigeonpea is associated with two distinct emaraviruses, Pigeonpea sterility mosaic virus 1 (PPSMV-1) and Pigeonpea sterility mosaic virus 2 (PPSMV-2), with genomes consisting of five and six negative-sense RNA segments, respectively. The recently published genome sequences of both PPSMV-1 and PPSMV-2 are from a single location, Patancheru from the state of Telangana in India. However, here we present the first report of sequence variability among 23 isolates of PPSMV-1 and PPSMV-2, collected from ten locations representing six states of India. Both PPSMV-1 and PPSMV-2 are shown to be present across India and to exhibit considerable sequence variability. Variability of RNA3 sequences was higher than the RNA4 sequences for both PPSMV-1 and PPSMV-2. Additionally, the sixth RNA segment (RNA6), previously reported to be associated with only PPSMV-2, is also associated with isolates of PPSMV-1. Multiplex reverse transcription PCR (RT-PCR) analyses show that PPSMV-1 and PPSMV-2 frequently occur as mixed infections. Further sequence analyses indicated the presence of reassortment of RNA4 between isolates of PPSMV-1 and PPSMV-2. PMID:28696402

The aim of this study was to examine the association between CD4 count, human papilloma virus (HPV) infection, and the risk of cervical intraepithelial neoplasia among HIV-infected women. A cross-sectional study was conducted among 104 HIV-infected women attending an antiretroviral therapy clinic. They underwent Pap smear and cervical HPV DNA testing. The overall prevalence of HPV infection was 57.7%. HPV 16 was the commonest genotype found (38.5%); HPV 16 and 18 put together contributed to 73.3% of HPV infection; 27.5% of HIV-infected women had squamous cell abnormalities. Cervical intraepithelial neoplasia was less likely among women with CD4 count > 500/mm 3 (12%) and in those without opportunistic infections (17.8%). The prevalence of high-risk HPV infection was higher in women with high-grade squamous intraepithelial lesions or greater lesions (85.7%) as compared to women with normal cytology (52.1%). The high prevalence of HPV infection and cervical intraepithelial neoplasia in HIV-infected women warrants the need for regular Pap smear screening in these women and routine HPV vaccination for adolescents to reduce the burden of cervical cancer in India. © 2016 Japan Society of Obstetrics and Gynecology.

Biology and interactions of two distinct monopartite begomoviruses and betasatellites associated with radish leaf curl disease in India

Full Text Available Abstract Background Emerging whitefly transmitted begomoviruses are major pathogens of vegetable and fibre crops throughout the world, particularly in tropical and sub-tropical regions. Mutation, pseudorecombination and recombination are driving forces for the emergence and evolution of new crop-infecting begomoviruses. Leaf curl disease of field grown radish plants was noticed in Varanasi and Pataudi region of northern India. We have identified and characterized two distinct monopartite begomoviruses and associated beta satellite DNA causing leaf curl disease of radish (Raphanus sativus in India. Results We demonstrate that RaLCD is caused by a complex of two Old World begomoviruses and their associated betasatellites. Radish leaf curl virus-Varanasi is identified as a new recombinant species, Radish leaf curl virus (RaLCV sharing maximum nucleotide identity of 87.7% with Tomato leaf curl Bangladesh virus-[Bangladesh:2] (Accession number AF188481 while the virus causing radish leaf curl disease-Pataudi is an isolate of Croton yellow vein mosaic virus-[India] (CYVMV-IN (Accession number AJ507777 sharing 95.8% nucleotide identity. Further, RDP analysis revealed that the RaLCV has a hybrid genome, a putative recombinant between Euphorbia leaf curl virus and Papaya leaf curl virus. Cloned DNA of either RaLCV or CYVMV induced mild leaf curl symptoms in radish plants. However, when these clones (RaLCV or CYVMV were individually co-inoculated with their associated cloned DNA betasatellite, symptom severity and viral DNA levels were increased in radish plants and induced typical RaLCD symptoms. To further extend these studies, we carried out an investigation of the interaction of these radish-infecting begomoviruses and their associated satellite, with two tomato infecting begomoviruses (Tomato leaf curl Gujarat virus and Tomato leaf curl New Delhi virus. Both of the tomato-infecting begomoviruses showed a contrasting and differential interaction with

Identification of blood meals of vector mosquitoes is an important tool in the epidemiological investigations of vector-borne diseases. The blood meals of three mosquito species involved in the transmission of Japanese encephalitis virus (JEV) from the Kuttanadu area, Kerala, were determined using the agarose gel diffusion technique. A total of 4959 blood smears belonging to Culex (Culex) tritaeniorhynchus Giles (3273), Cx. (Culex) gelidus Theobald (64), Mansonia (Mnd.) indiana Edwards (735) ,and Ma. (Mnd.) uniformis (Theobald) (887) were tested. Cx. tritaeniorhynchus had predominantly fed on bovids (46.4%), and a good proportion (29%) had fed on more than one host. Cx. tritaeniorhynchus was highly zoophagic, and human feeding accounted for only 1.5% of those individuals successfully tested. Cx. gelidus showed bovid feeding at 36% and pig feeding at 12.5%. The test results showed 42.3% Ma. indiana and 12.2% Ma. uniformis had fed on humans. Multiple feeding was observed in Ma. indiana and Ma. uniformis, and most of the double feedings were from bovids and ovids (7.9 and 20.1%, respectively). Pig feeding accounted for 4.8% of the feedings by Cx. tritaeniorhynchus, 5.3% of Ma. indiana, and 6.4% of Ma. uniformis. This study is significant because of the role played by these mosquitoes in the transmission of JEV in the Kuttanadu area of Kerala, India.

Samples of two Ageratum conyzoides, one Sonchus oleraceus and one turnip (Brassica rapa var. rapa) exhibiting virus-like symptoms were collected from Pakistan and Nepal. Full-length begomovirus clones were obtained from the four plant samples and betasatellite clones from three of these. The begomovirus sequences were shown to be isolates of Ageratum enation virus (AEV) with greater than 89.1% nucleotide sequence identity to the 26 AEV sequences available in the databases. The three betasatellite sequences were shown to be isolates of Ageratum yellow leaf curl betasatellite (AYLCB) with greater than 90% identity to the 18 AYLCB sequences available in the databases. The AEV sequences were shown to fall into two distinct strains, for which the names Nepal (consisting of isolates from Nepal, India, and Pakistan-including the isolates identified here) and India (isolates occurring only in India) strains are proposed. For the clones obtained from two AEV isolates, with their AYLCB, infectivity was shown by Agrobacterium-mediated inoculation to Nicotiana benthamiana, N. tabacum, Solanum lycopersicon and A. conyzoides. N. benthamiana plants infected with AEV alone or betasatellite alone showed no symptoms. N. benthamiana plants infected with AEV with its associated betasatellite showed leaf curl symptoms. The findings show that AEV is predominantly a virus of weeds that has the capacity to infect crops. AYLCB appears to be the common partner betasatellite of AEV and is associated with diseases with a range of very different symptoms in the same plant species. The inability to satisfy Koch's postulates with the cloned components of isolate SOL in A. conyzoides suggests that the etiology may be more complex than a single virus with a single betasatellite.

In this discussion of India attention is directed to the following: the people; geography; history; government; political conditions; the economy; foreign relations (Pakistan and Bangladesh, China, and the Soviet Union); defense; and the relations between the US and India. In 1983 India's population was estimated at 746 million with an annual growth rate of 2.24%. The infant mortality rate was estimated at 116/1000 in 1984 with a life expectancy of 54.9 years. Although India occupies only 2.4% of the world's land area, it supports nearly 15% of the world's population. 2 major ethnic strains predominate in India: the Aryan in the north and the Dravidian in the south, although the lines between them are blurred. India dominates the South Asian subcontinent geographically. The people of India have had a continuous civilization since about 2500 B.C., when the inhabitants of the Indus River Valley developed an urban culture based on commerce, trade, and, to a lesser degree, agriculture. This civilization declined about 1500 B.C. and Aryan tribes originating in central Asia absorbed parts of its culture as they spread out over the South Asian subcontinent. During the next few centuries, India flourished under several successive empires. The 1st British outpost in South Asia was established in 1619 at Surat on the northwestern coast of India. The British gradually expanded their influence until, by the 1850s, they controlled almost the entire area of present-day India. Independence was attained on August 15, 1947, and India became a dominion within the Commonwealth of Nations with Jawaharlal Nehru as prime minister. According to its constitution, India is a "sovereign socialist secular democratic republic." Like the US, India has a federal form of government, but the central government in India has greater power in relation to its states, and government is patterned after the British parliamentary system. The Congress Party has ruled India since independence with the

The present study for the first time describes biological and molecular characterization of Citrus tristeza virus (CTV) occurring in the Terai area of Uttarakhand State in Northern Himalaya region of India. Direct antigen coated-ELISA and reverse transcriptase-polymerase chain reaction (RT-PCR) detected the CTV infection in Acid lime cv. Pant lemon (Citrus aurantifolia) orchards of Pantnagar with an estimated disease incidence of 16.6-20.5 %. To know the biological and genetic properties, an isolate, CTV Pant 4 was characterized. Isolate Pant 4 could be graft transmitted to Kinnow, Nagpur and Darjeeling mandarins, Mosambi sweet orange, Kagzi lime, Sweet lime, Sour orange but not to Rough lemon. The sequence analyses of the 5'ORF1a (3038 nucleotides) of LPro domain and 3'end (2058 nt) covering ORF7-ORF10 regions of the CTV genome revealed that Pant 4 was closely related to the previously reported Indian CTV isolate, Kpg3 from Northeastern Himalaya region with 97 and 98 % sequence identity, respectively. Whereas, it differed from the previously reported CTV isolate B165 from Southern India with 79 and 92 % identity, respectively for 5'ORF1a and 3' end regions. Recombination and SplitsTree decomposition analyses indicated that CTV isolate Pant 4 was a recombinant isolate originating from Kpg3 as a major and B165 as a minor donor.

Chikungunya virus (CHIKV) is an Alphavirus belonging to the family Togaviridae. In 2006, CHIKV infection struck the Andaman and Nicobar archipelago, with an attack rate of 60%. There were more than 10 cases with acute flaccid paralysis simulating the Guillian Barre Syndrome. The majority of the patients presented severe joint pain. The cause for such an explosive nature of the outbreak with increased morbidity was not known. The isolation of CHIKV was attempted and succeeded from nine subjects presenting clinical symptoms of Chikungunya fever. The cDNA of all the isolates was sequenced for partial E1 and nsP1 genes. Sequences were aligned based on the double locus sequence typing concept. The phylogenetic analysis shows that sequences of Andaman isolates grouped with the East, Central, and South African genotype of virus isolates from India, Sri Lanka, and Réunion. The genetic distance between Andaman isolates and the Réunion isolates was very small. The phylogenetic analysis confirmed the origin of the isolates responsible for the first ever confirmed CHIKV outbreak in these islands to be the East, Central, and South African genotype. In this manuscript, we discuss the involvement of the East, Central, and South African strain with the Chikungunya fever outbreak in this archipelago and double locus sequence typing as a first time approach.

Canine distemper (CD), caused by canine distemper virus (CDV) is a highly contagious disease that infects a variety of carnivores. Sequence analysis of CDVs from different geographical areas has shown a lot of variation in the genome of the virus especially in haemagglutinin gene which might be one of the causes of vaccine failure. In this study, we isolated the virus (place: Ludhiana, Punjab; year: 2014) and further cloned, sequenced and analyzed partial haemagglutinin (H) gene and full length genes for fusion protein (F), phosphoprotein (P) and matrix protein (M) from an Indian wild-type CDV. Higher sequence homology was observed with the strains from Switzerland, Hungary, Germany; and lower with the vaccine strains like Ondersteport, CDV3, Convac for all the genes. The multiple sequence alignment showed more variation in partial H (45 nucleotide and 5 amino acid substitutions) and complete F (79 nucleotide and 30 amino acid substitutions) than in complete P (44 nucleotide and 22 amino acid substitutions) and complete M (22 nucleotide and 4 amino acid substitutions) gene/protein. Predicted potential N-linked glycosylation sites in H, F, M and P proteins were similar to the previously known wild-type CDVs but different from the vaccine strains. The Indian CDV formed a distinct clade in the phylogenetic tree clearly separated from the previously known wild-type and vaccine strains.

Ancient ancestry of KFDV and AHFV revealed by complete genome analyses of viruses isolated from ticks and mammalian hosts.

Full Text Available BACKGROUND: Alkhurma hemorrhagic fever virus (AHFV and Kyasanur forest disease virus (KFDV cause significant human disease and mortality in Saudi Arabia and India, respectively. Despite their distinct geographic ranges, AHFV and KFDV share a remarkably high sequence identity. Given its emergence decades after KFDV, AHFV has since been considered a variant of KFDV and thought to have arisen from an introduction of KFDV to Saudi Arabia from India. To gain a better understanding of the evolutionary history of AHFV and KFDV, we analyzed the full length genomes of 16 AHFV and 3 KFDV isolates. METHODOLOGY/PRINCIPAL FINDINGS: Viral genomes were sequenced and compared to two AHFV sequences available in GenBank. Sequence analyses revealed higher genetic diversity within AHFVs isolated from ticks than human AHFV isolates. A Bayesian coalescent phylogenetic analysis demonstrated an ancient divergence of AHFV and KFDV of approximately 700 years ago. CONCLUSIONS/SIGNIFICANCE: The high sequence diversity within tick populations and the presence of competent tick vectors in the surrounding regions, coupled with the recent identification of AHFV in Egypt, indicate possible viral range expansion or a larger geographic range than previously thought. The divergence of AHFV from KFDV nearly 700 years ago suggests other AHFV/KFDV-like viruses might exist in the regions between Saudi Arabia and India. Given the human morbidity and mortality associated with these viruses, these results emphasize the importance of more focused study of these significant public health threats.

Full Text Available Background: Dengue virus serotyping is crucial from clinical management and epidemiological point of view. Aims: To compare efficacy of two molecular detection and typing methods, namely, multiplex reverse transcription polymerase chain reaction (RT-PCR and real-time Hybprobe assay using a panel of known dilution of four reference Dengue virus strains and a panel of sera collected from clinically suspected dengue patients. Settings: This study was conducted at a tertiary-care teaching hospital in Delhi, India. Materials and Methods: Dengue serotype specific virus strains were used as prototypes for serotyping assays. Viral load was quantified by quantitative real time reverse transcription polymerase chain reaction (qRT-PCR. Acute phase serum samples were collected from 79 patients with clinically suspected Dengue fever on their first day of presentation during September-October 2012. Viral RNA from serum and cell culture supernatant was extracted. Reverse transcription was carried out. Quantitative detection of DENV RNA from reference strain culture supernatants and each of the 79 patient samples by real-time PCR was performed using light cycler Taqman master mix kit. Serotyping was done by multiplex RT-PCR assay and Hybprobe assay. Results: The multiplex RT-PCR assay, though found to be 100% specific, couldn't serotype either patient or reference strains with viral load less than 1000 RNA copies/ml. The Hybprobe assay was found to have 100% specificity and had a lower limit of serotype detection of merely 3.54 RNA copies/ml. Conclusions: HybProbe assay has an important role especially in situations where serotyping is to be performed in clinical samples with low viral load.

The cave is located in the Ananthagiri hills of the Eastern Ghats region near Visakhapattanam and is made of limestone. The emotion of thrill heightens after entering the cave. The entrance has a narrow vertical opening and is well lit. Due to its location in the sub-equatorial region, dripping of water from the cave roofs occurs almost throughout the year. The formation of stalactites and stalagmites create wonderful phenomena specially found in this cave. The conspicuous pillars formed due to the joining of the roof and the floors are an awe-inspiring creativity of the creator of this world. Various viruses and bacteria are in the cave interior along with different other creatures. The Borra cave helps the Govt. of Andhra Pradesh, India, to earn huge economic benefits for the sake of tourism industry.

A disease outbreak of A (H1N1) PDM09 was reported in Andaman and Nicobar islands in 2009 with an attack rate of 33.5% among settler population and 26.3% among the aboriginal Nicobarese tribe. During the ongoing outbreak of A (H1N1) PDM09 disease in different parts of the world, a subject working in Dubai city of Saudi Arabia, came to Port Blair, following which the pandemic triggered for the first time in these Islands. During the period August 2009 to January 2011, 30 confirmed cases of Influenza A (H1N1) PDM09 virus infection was detected. To understand the genetic relationship, the NA gene sequences of the viruses were phylogenetically analysed together along with the virus sequence isolated from other parts of the world. Formation of multiple clusters were observed, with the sequences of Andaman Islands, mainland India, Mexico, Saudi Arabia and few other counties clustering together. The sequence analysis data revealed that there was no specific mutation conferring resistance to oseltamivir among the Andaman A (H1N1) PDM09 virus isolates. The result of phylogenetic analysis have also revealed that the A (H1N1) PDM09 virus might have spread in these remote Islands of India via the subject from Saudi Arabia/Dubai. A (H1N1) PDM09 Influenza outbreak have highlighted the need to strengthen the region-specific pandemic preparedness plans and surveillance strategies.

Sexually transmitted infections in India: Current status (except human immunodeficiency virus/acquired immunodeficiency syndrome

Full Text Available Sexually transmitted infections (STIs are more dynamic than other infections prevailing in the community. It is important that such dynamic epidemiological changes in STIs are acknowledged and kept track of in a vast and populous developing country like India, particularly in this HIV era. It is with this aim that the authors have reviewed the relevant literature in STI epidemiology in India during the past 25 years. Admittedly, there has been heterogeneity of data to account for the subcontinental dimension of this country. But a basic pattern in the changing epidemiology is discernible. Like the developed countries, in India too the bacterial STIs like chancroid and gonorrhea are declining, while viral STIs like HPV and herpes genitalis are on an upswing. The overall decline in the prevalence of STIs has to be interpreted with caution, however. This may partially reflect the improved facilities of treatment in the peripheral centres that obviates the need of many patients in attending the STD clinics in the tertiary centres. Also, the improved pharmacotherapy of many of the bacterial STIs may result in partial clearance and non-reporting of many of these infections.

The recent discovery of numerous hantaviruses in insectivores has provided a new view of hantavirus biodiversity and evolution. To determine the presence and genetic diversity of Imjin virus (MJNV) and Thottapalayam virus (TPMV) in insectivores in Zhejiang Province, China, we captured and performed virus screening of 32 Ussuri white-toothed shrews (Crocidura lasiura) and 105 Asian house shrews (Suncus murinus) in different coastal regions. Hantavirus genome (S, M, and L segments) sequences were successfully recovered from one Ussuri white-toothed shrew and seven Asian house shrews. Phylogenetic analysis revealed that the virus carried by the Ussuri white-toothed shrew was most closely related to MJNV, but with >15% nucleotide sequence difference, suggesting that it represents a new subtype. The hantaviruses carried by Asian house shrews were closely related to the TPMV variants found in the same geographic area, but more distantly related to those sampled in India and Nepal. Additionally, the TPMV sequences obtained in this study, as well as those found previously in this area, could be divided into three lineages reflecting their geographic origins, indicative of largely allopatric evolution. Overall, our data highlights the high genetic diversity of insectivore-borne hantaviruses in China, suggesting that more may be discovered in the future. Copyright © 2014 Elsevier B.V.

A widely held concern is that the pace of infectious disease emergence has been increasing. We have analyzed the rate of discovery of pathogenic viruses, the preeminent source of newly discovered causes of human disease, from 1897 through 2010. The rate was highest during 1950-1969, after which it moderated. This general picture masks two distinct trends: for arthropod-borne viruses, which comprised 39% of pathogenic viruses, the discovery rate peaked at three per year during 1960-1969, but subsequently fell nearly to zero by 1980; however, the rate of discovery of nonarboviruses remained stable at about two per year from 1950 through 2010. The period of highest arbovirus discovery coincided with a comprehensive program supported by The Rockefeller Foundation of isolating viruses from humans, animals, and arthropod vectors at field stations in Latin America, Africa, and India. The productivity of this strategy illustrates the importance of location, approach, long-term commitment, and sponsorship in the discovery of emerging pathogens.

An ethics panel, convened by the National Institute of Health and other research bodies in the USA, disallowed researchers from the Johns Hopkins University and University of Vermont from performing controlled human infection of healthy volunteers to develop a vaccine against Zika virus infection. The members published their ethical analysis and recommendations in February 2017. They have elaborated on the risks posed by human challenge with Zika virus to the volunteers and other uninvolved third parties and have systematically analysed the social value of such a human challenge experiment. They have also posited some mandatory ethical requirements which should be met before allowing the infection of healthy volunteers with the Zika virus. This commentary elaborates on the debate on the ethics of the human challenge model for the development of a Zika virus vaccine and the role of systematic ethical analysis in protecting the interests of research participants. It further analyses the importance of this debate to the development of a Zika vaccine in India.

Japanese encephalitis (JE) is endemic in many parts of India including the state of West Bengal. In West Bengal, the first major outbreaks of JE occurred in the districts of Bankura and Burdwan in 1973. The Culex vishnui subgroup of mosquitoes has been implicated as major vectors of JE. However in India, JE virus (JEV) has been isolated from 16 species of mosquitoes. During September 2011, JE cases were reported from four districts -Jalpaiguri, Darjeeling, Dinajpur and Cooch Behar of West Ben...

Methods and Results: During the nine year period of this study analysis, 6767 strongly suspected cases were tested by RT-PCR. 1685 (24.9% were Dengue PCR positive and confirmed as Dengue cases. Observations on the seasonality were based on the nine year's data as the intensity of sampling was at its maximum during monsoon season. Dengue typing was done on 100 positive samples after storage of Dengue RNA at – 80°C. Dengue serotypes were detected in 69 samples of which Dengue 2 was most predominant. 576 samples were processed for NS1 antigen and PCR simultaneously. 19/576 were positive (3.3 % for NS1 as well as by PCR . 23/576 samples were negative for NS1 antigen, but were positive by RT-PCR. The remaining 534 samples which were negative for NS1 antigen were also negative by Dengue RT-PCR. Conclusion: In this study we sought to standardize rapid, sensitive, and specific fluorogenic probe-based RT-PCR assay to screen and serotype a representative range of Dengue viruses that are found in and around Mumbai. Qualitative Dengue virus TaqMan assays could have tremendous utility for the epidemiological investigation of Dengue illness and especially for the study of the viremic response with candidate live-attenuated dengue virus vaccines.

Full Text Available Abstract Background Dengue virus type 1 (DENV-1 have been mostly circulating silently with dominant serotypes DENV-2 and DENV-3 in India. However recent times have marked an increase in DENV-1 circulation in yearly outbreaks. Many studies have not been carried out on this virus type, leaving a lacunae pertaining to the circulating genotypes, since its earliest report in India. In the present study, we sequenced CprM gene junction of 13 DENV-1 isolated from Delhi and Gwalior (North India between 2001–2007 and one 1956 Vellore isolate as reference. For comparison, we retrieved 11 other Indian and 70 global reference sequences from NCBI database, making sure that Indian and global isolates from all decades are available for comparative analysis. Results The region was found to be AT rich with no insertion or deletion. Majority of the nucleotide substitutions were silent, except 3 non-conservative amino acid changes (I → T, A → T and L → S at amino acid positions 59,114 and 155 respectively in the Indian DENV-1 sequences, sequenced in this study. Except two 1997–98 Delhi isolates, which group in genotype I; all other Indian isolates group in genotype III. All Indian genotype III DENV-1 exhibited diversity among them, giving rise to at least 4 distinct lineages (India 1–4 showing proximity to isolates from diverse geographic locations. Conclusion The extensive phylogenetic analysis revealed consistent existence of multiple lineages of DENV-1 genotype III during the last 5 decades in India.

Recombinant measles virus vaccine expressing the Nipah virus glycoprotein protects against lethal Nipah virus challenge.

Directory of Open Access Journals (Sweden)

Misako Yoneda

Full Text Available Nipah virus (NiV is a member of the genus Henipavirus, which emerged in Malaysia in 1998. In pigs, infection resulted in a predominantly non-lethal respiratory disease; however, infection in humans resulted in over 100 deaths. Nipah virus has continued to re-emerge in Bangladesh and India, and person-to-person transmission appeared in the outbreak. Although a number of NiV vaccine studies have been reported, there are currently no vaccines or treatments licensed for human use. In this study, we have developed a recombinant measles virus (rMV vaccine expressing NiV envelope glycoproteins (rMV-HL-G and rMV-Ed-G. Vaccinated hamsters were completely protected against NiV challenge, while the mortality of unvaccinated control hamsters was 90%. We trialed our vaccine in a non-human primate model, African green monkeys. Upon intraperitoneal infection with NiV, monkeys showed several clinical signs of disease including severe depression, reduced ability to move and decreased food ingestion and died at 7 days post infection (dpi. Intranasal and oral inoculation induced similar clinical illness in monkeys, evident around 9 dpi, and resulted in a moribund stage around 14 dpi. Two monkeys immunized subcutaneously with rMV-Ed-G showed no clinical illness prior to euthanasia after challenge with NiV. Viral RNA was not detected in any organ samples collected from vaccinated monkeys, and no pathological changes were found upon histopathological examination. From our findings, we propose that rMV-NiV-G is an appropriate NiV vaccine candidate for use in humans.

Chikungunya virus adapts to tiger mosquito via evolutionary convergence: a sign of things to come?

Higgs Stephen

2008-02-01

Full Text Available Abstract Since 2004, several million indigenous cases of Chikungunya virus disease occurred in Africa, the Indian Ocean, India, Asia and, recently, Europe. The virus, usually transmitted by Aedes aegypti mosquitoes, has now repeatedly been associated with a new vector, Ae. Albopictus. Analysis of full-length viral sequences reveals three independent events of virus exposure to Ae. Albopictus, each followed by the acquisition of a single adaptive mutation providing selective advantage for transmission by this mosquito. This disconcerting and current unique example of "evolutionary convergence" occurring in nature illustrates rapid pathogen adaptation to ecological perturbation, driven directly as a consequence of human activities.

Coat protein (CP) and RNA3 from Prunus necrotic ringspot virus (PNRSV-rose), the most prevalent virus infecting rose in India, were characterized and regions in the coat protein important for self-interaction, during dimer formation were identified. The sequence analysis of CP and partial RNA 3 revealed that the rose isolate of PNRSV in India belongs to PV-32 group of PNRSV isolates. Apart from the already established group specific features of PV-32 group member's additional group-specific and host specific features were also identified. Presence of methionine at position 90 in the amino acid sequence alignment of PNRSV CP gene (belonging to PV-32 group) was identified as the specific conserved feature for the rose isolates of PNRSV. As protein-protein interaction plays a vital role in the infection process, an attempt was made to identify the portions of PNRSV CP responsible for self-interaction using yeast two-hybrid system. It was found (after analysis of the deletion clones) that the C-terminal region of PNRSV CP (amino acids 153-226) plays a vital role in this interaction during dimer formation. N-terminal of PNRSV CP is previously known to be involved in CP-RNA interactions, but our results also suggested that N-terminal of PNRSV CP represented by amino acids 1-77 also interacts with C-terminal (amino acids 153-226) in yeast two-hybrid system, suggesting its probable involvement in the CP-CP interaction.

Highlights: •Complete genome of Indian DENV-2 was deciphered for the first time in this study. •The recent Indian DENV-2 revealed presence of many unique amino acid residues. •Genotype shift (American to Cosmopolitan) characterizes evolution of DENV-2 in India. •Circulation of a unique clade of DENV-2 in South Asia was identified. -- Abstract: Dengue is the most important arboviral infection of global public health significance. It is now endemic in most parts of the South East Asia including India. Though Dengue virus type 2 (DENV-2) is predominantly associated with major outbreaks in India, complete genome information of Indian DENV-2 is not available. In this study, the full-length genome of five DENV-2 isolates (four from 2001 to 2011 and one from 1960), from different parts of India was determined. The complete genome of the Indian DENV-2 was found to be 10,670 bases long with an open reading frame coding for 3391 amino acids. The recent Indian DENV-2 (2001–2011) revealed a nucleotide sequence identity of around 90% and 97% with an older Indian DENV-2 (1960) and closely related Sri Lankan and Chinese DENV-2 respectively. Presence of unique amino acid residues and non-conservative substitutions in critical amino acid residues of major structural and non-structural proteins was observed in recent Indian DENV-2. Selection pressure analysis revealed positive selection in few amino acid sites of the genes encoding for structural and non-structural proteins. The molecular phylogenetic analysis based on comparison of both complete coding region and envelope protein gene with globally diverse DENV-2 viruses classified the recent Indian isolates into a unique South Asian clade within Cosmopolitan genotype. A shift of genotype from American to Cosmopolitan in 1970s characterized the evolution of DENV-2 in India. Present study is the first report on complete genome characterization of emerging DENV-2 isolates from India and highlights the circulation of a

Violence against women is a global phenomenon that cuts across all social and economic classes. This study was designed to measure the prevalence and correlates of domestic violence (DV) among women seeking services at a voluntary counseling and testing (VCT) center in Bangalore, India. A cross-sectional survey was conducted among women visiting an human immunodeficiency virus (HIV) VCT center in Bangalore, between September and November 2005. An interviewer-administered questionnaire was used to collect information about violence and other variables. Univariable associations with DV were made using Pearson Chi-squared test for categorical variables and Student t-test or the Mann-Whitney test for continuous variables. Forty-two percent of respondents reported DV, including physical abuse (29%), psychological abuse (69%) and sexual abuse (1%). Among the women who reported violence of any kind, 67% also reported that they were HIV seropositive. The most common reasons reported for DV included financial problems (38%), husband's alcohol use (29%) and woman's HIV status (18%). Older women (P around the world. The findings highlight the need for additional training among health care providers in VCT centers in screening for DV, detection of signs of physical abuse and provisions and referrals for women suffering from domestic partner violence.

Cervical cancer is one of the commonest cancers among women all over the world. The association of cervical cancer with human papilloma virus (HPV) is well established. Knowledge about the causal relationship between HPV and cervical cancer is important to make appropriate, evidence-based health care choices. In this context we conducted a community based study among women about the knowledge, attitude and practice about HPV infections and their health effects. A cross sectional interview based house to house survey was conducted with a validated data collection tool covering sociodemographic factors, knowledge, attitude and practice about HPV and its health effects, among 1020 women from a rural village, Perdoor, in Udupi district, Karnataka, India in 2013-14. The mean age of participants was 38.9 years (SD=12.6). Study participants showed a high literacy rate (85.7%). Only 2.4% of sexually exposed women had undergone Pap smear testing. Partners of 4.4%women had undergone circumcision and they belonged to the Muslim community. Male condom usage was reported by 26 women (2.6%). However, none of the participants had heard of HPV and its health effects. This community based study found complete ignorance about HPV among rural South Indian women in spite of a high literacy level.

Foot-and-mouth disease (FMD) is endemic in Bangladesh, and to implement an effective FMD control programme, it is essential to understand the complex epidemiology of the disease. Here, we report on the characterization of FMD virus (FMDV) recovered from FMD outbreaks in Bangladesh in late 2009. All isolated viruses belonged to the FMDV serotype O. The phylogenetic reconstruction showed that all isolates belonged to the Middle East-South Asia (ME-SA) topotype, but fell into two distinct sublineages, one named Ind-2001 (the other has not been named). Within both sublineages, the 2009 Bangladesh isolates were most closely related to viruses from Nepal collected during 2008 and 2009. Additionally, both sublineages contained older viruses from India collected in 2000 and 2001. In South Asia, there is extensive cross-border cattle movement from Nepal and India to Bangladesh. Both these findings have implications for the control of FMD in Bangladesh. Because of the porous borders, a regional FMD control strategy should be developed. Further, animal identification and monitoring animal movements are necessary to identify the cross-border movements and market chain interactions of ruminants, leading to improved border and movement controls. Additionally, a vaccination strategy should be developed with the initial objective of protecting small-scale dairy herds from disease. For any successful FMD control programme, long-term Government commitment and adequate resources are necessary. A sustainable programme will also need farmer education, commitment and financial contributions. © 2011 Blackwell Verlag GmbH.

Microbiological analysis of samples collected from cases of white spot disease outbreaks in cultured shrimp in different farms located in three regions along East Coast of India viz. Chidambram (Tamil Nadu), Nellore (Andhra Pradesh) and Balasore (Orissa), revealed presence of Vibrio alginolyticus, Vibrio parahaemolyticus, and Aeromonas spp. but experimental infection trials in Penaeus monodon with these isolates did not induce any acute mortality or formation of white spots on carapace. Infection trials using filtered tissue extracts by oral and injection method induced mortality in healthy P. monodon with all samples and 100% mortality was noted by the end of 7 day post-inoculation. Histopathological analysis demonstrated degenerated cells characterized by hypertrophied nuclei in gills, hepatopancreas and lymphoid organ with presence of intranuclear basophilic or eosino-basophilic bodies in tubular cells and intercellular spaces. Analysis of samples using 3 different primer sets as used by other for detection of white spot syndrome virus (WSSV) generated 643, 1447 and 520bp amplified DNA products in all samples except in one instance. Variable size virions with mean size in the range of 110 x 320 +/- 20 nm were observed under electron microscope. It could be concluded that the viral isolates in India involved with white spot syndrome in cultured shrimp are similar to RV-PJ and SEMBV in Japan, WSBV in Taiwan and WSSV in Malaysia, Indonesia, Thailand, China and Japan.

Full Text Available Objective: The objective of this study is to delineate the clinical and laboratory profile of infectious mononucleosis due to Epstein-Barr virus (EBV infection in children admitted to tertiary care teaching hospitals. Materials and Methods: Retrospective observational multicentric analysis of clinical and laboratory features of children between 1 month to 12 years with a diagnosis of infectious mononucleosis due to EBV infection confirmed by positive serology over a 12-month period after seeking approval from the Institutional Ethics Committee. Results: Out of 66 children screened, 53 were included in final analysis. The majority were aged between 5 and 8 years with male: female ratio of 1.2:1. Most presentations were during the monsoon months. The common clinical features were fever (100%, splenomegaly (86.7%, and cervical lymphadenopathy (73.5% in contrast to the classical triad of fever, sore throat, and generalized lymphadenopathy described in the literature. There were no age differences in clinical findings except for generalized and cervical lymphadenopathy and hepatomegaly which were commoner in 9–12 years age band. Although the incidence of common findings matched with previously published studies, there were some notable differences. While frequencies of upper eyelid edema, epitrochlear lymphadenopathy, and splenomegaly were more, those of rash and sore throat were less. Lymphocytosis and presence of atypical lymphocytes were relatively less common in our series. All children recovered. Conclusions: This multicentric study on profiling childhood infectious mononucleosis, possibly first of its kind from Eastern India, has documented clinical and laboratory features associated with this condition. These data can serve as a reference for future studies.

Mean age of patients was 35.1 ± 9.0 years. Majority (91.8% of patients were in the age group of 15 to 49 years. Progressively increasing proportion of female patients was noted from year 2004 onward. Median CD4 count at presentation in year 2003 was 197/μl (Interquartile range [IQR] = 82.5-373 while in year 2007 it was 186.5/μl (IQR = 86.3-336.8. Mean CD4 count of male patients was 203.7 ± 169.4/μl, significantly lower as compared with female patients, which was 284.8 ± 223.3/μl (P value ≤0.05. Every year, substantial proportions of patients presenting to clinic had CD4 count<200/μl indicating advanced disease. Predominant route of transmission was heterosexual in 2 507 (81.7% patients. Tuberculosis and oropharyngeal candidiasis were the most common opportunistic infections (OIs. Cryptococcal meningitis was the most common central nervous infection. Our patients had comparatively lower median CD4 counts at the time of presentation with various OIs. Conclusions: Patients had advanced stage of HIV infection at the time of presentation throughout five years. Females presented earlier during the course of HIV infection. There is need for early screening and increasing awareness in healthcare providers to make a diagnosis of HIV much sooner.

The present study describes prevalence of peste des petits ruminants (PPR) virus infection in goats in various parts of North-East (NE) India by screening of suspected serum samples collected during outbreak investigation and random samples during 2013-2014 survey. A total of 391 serum samples (318 random and 73 outbreak/suspected) were collected from 28 districts in 7 states (Meghalaya, Assam, Manipur, Nagaland, Arunachal Pradesh, Tripura and Mizoram) of NE India. Serum samples were screened for PPRV-specific antibodies by using PPR monoclonal-antibody based competitive ELISA. Analysis of 391 serum samples indicates that an overall seroprevalence of 17.90 % [CI 95 % 14.40-22.00] in goats {45.2 % in suspected [CI 95 % 34.32-56.58] and 11.63 % in random [CI 95 % 8.56-15.63] samples} in NE India. As expected prevalence was high in outbreaks vis-à-vis random samples. The random survey results (11.63 %) has specific implication in epidemiological perspectives, since it highlights the exact PPR prevalence under natural situations, where the subclinical, in apparent or nonlethal or recovery of infection was suspected in goats, as samples were collected from unvaccinated animals. It also warrants appropriate control measures against PPR in NE region to prevent spread of infection besides widespread presence of the disease in rest of India.

The Crimean-Congo haemorrhagic fever virus (CCHFV), which is transmitted by the ticks of Hyalomma spp. in general and H. marginatumin particular, can cause severe disease in humans, with mortality rates of 3-30%. Other than from the bites of infected ticks, CCHFV can also be transmitted through contact with patients with the acute phase of infection or contact with blood or tissues from viraemic livestock.  Outbreaks of human cases of haemorrhagic manifestations have been documented since 1945 and described in parts of Africa, Asia, Eastern Europe and the Middle East and most recently India in 2011. In addition, serological evidence of the disease has been reported in some countries where no human cases were reported. As regional neighbours China and India have been affected by this virus, this study was conducted to determine the seroprevalence of CCHFV among Orang Asli population of Malaysia as the most at risk people who residing in the deep forests. A total of 682 serum samples were collected from the Orang Asli population residing in eight states in peninsular Malaysia and analysed for the presence of anti-CCHFV immunoglobulin G (IgG) using a commercial enzyme-linked immunosorbent assay kit. The study subjects comprised 277 (40.6%) men and 405 (59.4%) women. However, anti-CCHFV IgG was detected in only one female serum sample (0.1%). The presence of anti-CCHFV IgG could not be correlated to age or sex from these findings. The results of this screening survey showed that the seroprevalence of the anti-CCHFV IgG among Malaysia's Orang Asli population is too low for detection or totally negative compared with that in neighbouring countries, such as India and China.

Full Text Available Background: A significant number of safe donations are removed from the blood supply, because of the reactive anti-HCV screening test results. This study aimed to assess if the HCV (Hepatitis C Virus seropositive donors were confirmed positive or not. Materials and Methods: More than 68,000 blood donors′ samples were routinely screened and 140 samples were found to be anti-HCV ELISA reactive. These 140 samples were tested by NAT. The NAT negative samples were tested by RIBA. Analysis of samples reactive in single ELISA kit vs. two ELISA kits was done. Results: Out of 140 anti-HCV ELISA reactive samples, a total of 16 (11.43% were positive by NAT. The results of 124 RIBA showed 6 (4.84% positive, 92 (74.19% negative, and 26 (20.97% indeterminate results. None of the sample which was reactive in only single ELISA kit was positive by NAT or RIBA. Conclusion: Only a minority of blood donors with repeatedly reactive anti-HCV screening test is positive by confirmatory testing, but all these blood units are discarded as per existing legal provisions in India. Efforts should be made to retain these donors and also donor units.

The 1957 and 1968 influenza pandemics, each of which killed ≈1 million persons, arose through reassortment events. Influenza virus in humans and domestic animals could reassort and cause another pandemic. To identify geographic areas where agricultural production systems are conducive to reassortment, we fitted multivariate regression models to surveillance data on influenza A virus subtype H5N1 among poultry in China and Egypt and subtype H3N2 among humans. We then applied the models across Asia and Egypt to predict where subtype H3N2 from humans and subtype H5N1 from birds overlap; this overlap serves as a proxy for co-infection and in vivo reassortment. For Asia, we refined the prioritization by identifying areas that also have high swine density. Potential geographic foci of reassortment include the northern plains of India, coastal and central provinces of China, the western Korean Peninsula and southwestern Japan in Asia, and the Nile Delta in Egypt.

Full Text Available The paradigm of preventing human papilloma virus (HPV infection through currently approved vaccines, namely, Gardasil, manufactured by Merck and Co., Inc. (Whitehouse Station, NJ and Cervarix, manufactured by GlaxoSmithKline (GSK, Philadelphia holds tremendous promise for the developing countries in decreasing the burden of HPV infection and its sequelae, such as cervical cancer, genital warts and anogenital cancers. Effective screening programs that have reduced the burden of this killer disease in the developed countries are still lacking in India, despite the high incidence of cervical cancer and the implementation of the National Cancer Control Programme since 1975. The recent breakthrough in the global war against cervical cancer will provide new insight for meeting the future challenge of the prevention of cervical cancer in India.

Dengue surveillance relies on reverse transcription-polymerase chain reaction (RT-PCR), for confirmation of dengue virus (DENV) serotypes. We compared efficacies of published and modified primer sets targeting envelope (Env) and capsid-premembrane (C-prM) genes for detection of circulating DENV serotypes in southern India. Acute samples from children with clinically-diagnosed dengue were used for RT-PCR testing. All samples were also subjected to dengue serology (NS1 antigen and anti-dengue-IgM/IgG rapid immunochromatographic assay). Nested RT-PCR was performed on viral RNA using three methods targeting 654bp C-prM, 511bp C-prM and 641bp Env regions, respectively. RT-PCR-positive samples were validated by population sequencing. Among 171 children with suspected dengue, 121 were dengue serology-positive and 50 were dengue serology-negative. Among 121 serology-positives, RT-PCR detected 91 (75.2%) by CprM654, 72 (59.5%) by CprM511, and 74 (61.1%) by Env641. Among 50 serology-negatives, 10 (20.0%) were detected by CprM654, 12 (24.0%) by CprM511, and 11 (22.0%) by Env641. Overall detection rate using three methods sequentially was 82.6% (100/121) among serology-positive and 40.0% (20/50) among serology-negative samples; 6.6% (8/120) had co-infection with multiple DENV serotypes. We conclude that detection of acute dengue was enhanced by a modified RT-PCR method targeting the 654bp C-prM region, and further improved by using all three methods sequentially.

2018-04-01

Full Text Available Bagaza virus is a mosquito-borne flavivirus, first isolated in 1966 in Central African Republic. It has currently been identified in mosquito pools collected in the field in West and Central Africa. Emergence in wild birds in Europe and serological evidence in encephalitis patients in India raise questions on its genetic evolution and the diversity of isolates circulating in Africa. To better understand genetic diversity and evolution of Bagaza virus, we describe the full-genome characterization of 11 West African isolates, sampled from 1988 to 2014. Parameters such as genetic distances, N-glycosylation patterns, recombination events, selective pressures, and its codon adaptation to human genes are assessed. Our study is noteworthy for the observation of N-glycosylation and recombination in Bagaza virus and provides insight into its Indian origin from the 13th century. Interestingly, evidence of Bagaza virus codon adaptation to human house-keeping genes is also observed to be higher than those of other flaviviruses well known in human infections. Genetic variations on genome of West African Bagaza virus could play an important role in generating diversity and may promote Bagaza virus adaptation to other vertebrates and become an important threat in human health.

Cervical cancer is on the declining trend in India according to the population-based registries; yet it continues to be a major public health problem for women in India. Multifactorial causation, potential for prevention, and the sheer threat it poses make cervical cancer an important disease for in-depth studies, as has been attempted by this paper. This paper attempts to review the available knowledge regarding the epidemiology and pattern of cervical cancer; types of HPV (human papilloma virus) prevalent among cervical cancer patients and among women in general, high-risk groups such as commercial sex workers, and HIV (human immunodeficiency virus)-positive women; and the role of the national program on cancer in control efforts. The peak age of incidence of cervical cancer is 55-59 years, and a considerable proportion of women report in the late stages of disease. Specific types of oncogenic HPV-16, 18 have been identified in patients with cervical cancer. Other epidemiological risk factors are early age at marriage, multiple sexual partners, multiple pregnancies, poor genital hygiene, malnutrition, use of oral contraceptives, and lack of awareness. A multipronged approach is necessary which can target areas of high prevalence identified by registries with a combination of behavior change communication exercises and routine early screening with VIA. Sensitizing the people of the area, including menfolk, is necessary to increase uptake levels. Vaccination against types 16 and 18 can also be undertaken after taking into confidence all stakeholders, including the parents of adolescent girls. Preventing and treating cervical cancer and reducing the burden are possible by targeting resources to the areas with high prevalence.

Control strategies for peste des petits ruminants in small ruminants of India.

Science.gov (United States)

Singh, R P

2011-12-01

Peste des petits ruminants (PPR) is a contagious viral disease of small ruminants. It is endemic in several African, Middle Eastern and Asian countries, including India. India has recently taken comprehensive steps to deal with PPR through the development and production of potent vaccines and monoclonal-antibody-based diagnostic kits, while also gathering baseline information on the disease situation and human resources. As a result, PPR can now be controlled by focused vaccinations in high-risk populations of sheep and goats, followed by mass vaccination campaigns. Mass vaccination campaigns must achieve high levels of herd immunity (70% to 80%) to block the epidemic cycle of the virus. With the tools currently available, disease control and subsequent eradication programmes for PPR may be a feasible option, following the example of the National Rinderpest Eradication Programme, which has successfully eradicated rinderpest from India. An understanding of the cultural and socio-economic circumstances of goat and sheep owners and a keen watch on the endemic nature of PPR in neighbouring countries will enhance the success of this approach. Coordinated efforts from all stakeholders, combined with proper funding and execution of control programmes, will be needed to achieve the goal of a PPR-free India. In addition, the availability of effective combined vaccines of PPR with goat pox or sheep pox offers a cost-effective way of simultaneously launching control programmes against all three of these diseases.

Viral Diseases of Public Health Importance in India: Current Priorities with Special Emphasis on Prevention

Full Text Available India faces problems with both communicable and non communicable diseases. The major non communicable diseases are cancer, cardiovascular disease and diabetes mellitus. This article focuses on communicable diseases (infectious diseases especially viral infections of public health importance. The infections include bacterial, parasitic and viruses. It could be said that fungal infections by the nature of the spread are not of public health concern. The viral infections are transmitted by the respiratory route, water and food borne route, vectors and blood and blood products, sexual route and are of major concern. Efforts are aimed at early detection, prevention by use of vaccines and sentinel surveillance. For the success of public health programmes sentinel surveillance of diseases is mandatory. India has got several programme initiatives addressing the problem. The programs include IDSP, VBDCP and NACO. The approximate cumulative annual prevalence of infectious disease in India ranges from 100 to 200 million individuals affected in one year. India should aim to improve case detection by strengthening laboratory services with manpower training and nationwide quality control scheme, sentinel surveillance activity and prevention by improving the efficiency and scope of UIP. Also, creation of a single portal of infectious disease data handling hub to collect information from different sources will help avoid overlap and duplication of reporting.

Bats are known to be reservoirs of several medically important viruses including lyssaviruses. However, no systematic surveillance for bat rabies has been carried out in India, a canine rabies endemic country with a high burden of human rabies. Surveillance for rabies virus (RABV) infection in bats was therefore carried out in Nagaland, a north-eastern state in India at sites with intense human-bat interfaces during traditional bat harvests. Brain tissues and sera from bats were tested for evidence of infection due to RABV. Brain tissues were subjected to the fluorescent antibody test for detection of viral antigen and real-time reverse transcriptase PCR for presence of viral RNA. Bat sera were tested for the presence of rabies neutralizing antibodies by the rapid fluorescent focus inhibition test. None of the bat brains tested (n = 164) were positive for viral antigen or viral RNA. However, rabies neutralizing antibodies were detected in 4/78 (5·1%) bat sera tested, suggesting prior exposure to RABV or related lyssaviruses. The serological evidence of lyssaviral infection in Indian bats may have important implications in disease transmission and rabies control measures, and warrant extensive bat surveillance to better define the prevalence of lyssaviral infection in bats.

Banana and plantain (Musa spp.), produced in 10.3 million ha in the tropics, are among the world's top 10 food crops. They are vegetatively propagated using suckers or tissue culture plants and grown almost as perennial plantations. These are prone to the accumulation of pests and pathogens, especially viruses which contribute to yield reduction and are also barriers to the international exchange of germplasm. The most economically important viruses of banana and plantain are Banana bunchy top virus (BBTV), a complex of banana streak viruses (BSVs) and Banana bract mosaic virus (BBrMV). BBTV is known to cause the most serious economic losses in the "Old World," contributing to a yield reduction of up to 100% and responsible for a dramatic reduction in cropping area. The BSVs exist as episomal and endogenous forms are known to be worldwide in distribution. In India and the Philippines, BBrMV is known to be economically important but recently the virus was discovered in Colombia and Costa Rica, thus signaling its spread into the "New World." Banana and plantain are also known to be susceptible to five other viruses of minor significance, such as Abaca mosaic virus, Abaca bunchy top virus, Banana mild mosaic virus, Banana virus X, and Cucumber mosaic virus. Studies over the past 100 years have contributed to important knowledge on disease biology, distribution, and spread. Research during the last 25 years have led to a better understanding of the virus-vector-host interactions, virus diversity, disease etiology, and epidemiology. In addition, new diagnostic tools were developed which were used for surveillance and the certification of planting material. Due to a lack of durable host resistance in the Musa spp., phytosanitary measures and the use of virus-free planting material are the major methods of virus control. The state of knowledge on BBTV, BBrMV, and BSVs, and other minor viruses, disease spread, and control are summarized in this review. © 2015 Elsevier Inc

Full Text Available The genetic characterization of dengue virus type 3 (DEN-3 strains isolated from autochthonous cases in the State of Rio de Janeiro, Brazil, in 2001 is presented. Restriction site-specific (RSS-PCR performed on 22 strains classified the Brazilian DEN-3 viruses as subtype C, a subtype that contains viruses from Sri Lanka, India, Africa and recent isolates from Central America. Nucleic acid sequencing (positions 278 to 2550 of one DEN-3 strain confirmed the origin of these strains, since genotype III - classified by sequencing - and RSS-PCR subtype C are correlated. This genetic subtype has been associated with hemorrhagic dengue epidemics and the information provided here could be useful to implement appropriate prevention and control measures.

Full Text Available Objectives The survival outcomes of antiretroviral treatment (ART programs have not been systematically evaluated at the state level in India. This retrospective study assessed the survival rates and factors associated with survival among adult human immunodeficiency virus (HIV-infected patients in Andhra Pradesh, India. Methods The present study used data from 139 679 HIV patients aged ≥15 years on ART who were registered from 2007 to 2011 and were followed up through December 2013. The primary end point was death of the patient. Mortality densities (per 1000 person-years were calculated. Kaplan-Meier and Cox-regression models were used to estimate survival and explore the factors associated with survival. Results The overall median follow-up time was 16.0 months (2.0 months for the deceased and 14.0 months for those lost to follow-up. Approximately 13.2% of those newly initiated on ART died during follow-up. Of those deaths, 56% occurred in the first three months. The crude mortality rate was 80.9 per 1000 person-years at risk. The CD4 count (adjusted hazard ratio [aHR],4.88; 95% confidence interval [CI], 4.36 to 5.46 for 350 cells/mm3, functional status (aHR, 3.05; 95% CI, 2.82 to 3.30 for bedridden vs. normal, and body weight (aHR, 3.69; 95% CI, 3.42 to 3.97 for 60 kg were strongly associated with the survival of HIV patients. Conclusions The study findings revealed that high mortality was observed within the first three months of ART initiation. Patients with poor baseline clinical characteristics had a higher risk of mortality. Expanded testing and counseling should be encouraged, with the goal of ensuring early enrollment into the program followed by the initiation of ART in HIV-infected patients.

There is little research on HIV awareness and practices of traditional birth attendants (TBA) in India. This study investigated knowledge and attitudes among rural TBA in Karnataka as part of a project examining how traditional birth attendants could be integrated into prevention-of-mother-to-child transmission of HIV (PMTCT) programs in India. A cross-sectional survey was conducted between March 2008 and January 2009 among TBA in 144 villages in Mysore Taluk, Karnataka. Following informed consent, TBA underwent an interviewer-administered questionnaire in the local language of Kannada on practices and knowledge around birthing and HIV/PMTCT. Of the 417 TBA surveyed, the median age was 52 years and 96% were Hindus. A majority (324, 77.7%) had no formal schooling, 88 (21.1%) had up to 7 years and 5 (1%) had more than 7 yrs of education. Only 51 of the 417 TBA (12%) reported hearing about HIV/AIDS. Of those who had heard about HIV/AIDS, only 36 (72%) correctly reported that the virus could be spread from mother to child; 37 (74%) identified unprotected sex as a mode of transmission; and 26 (51%) correctly said healthy looking people could spread HIV. Just 22 (44%) knew that infected mothers could lower the risk of transmitting the virus to their infants. An overwhelming majority of TBA (401, 96.2%) did not provide antenatal care to their clients. Over half (254, 61%) said they would refer the woman to a hospital if she bled before delivery, and only 53 (13%) felt referral was necessary if excessive bleeding occurred after birth. Traditional birth attendants will continue to play an important role in maternal child health in India for the foreseeable future. This study demonstrates that a majority of TBA lack basic information about HIV/AIDS and safe delivery practices. Given the ongoing shortage of skilled birth attendance in rural areas, more studies are needed to examine whether TBA should be trained and integrated into PMTCT and maternal child health programs in

Avian influenza (AI) H9N2 has been reported from poultry in India. A seroepidemiological study was undertaken among poultry workers to understand the prevalence of antibodies against AI H9N2 in Pune, Maharashtra, India. A total of 338 poultry workers were sampled. Serum samples were tested for presence of antibodies against AI H9N2 virus by hemagglutination inhibition (HI) and microneutralization (MN) assays. A total of 249 baseline sera from general population from Pune were tested for antibodies against AI H9N2 and were negative by HI assay using ≥40 cut-off antibody titre. Overall 21 subjects (21/338 = 6.2%) were positive for antibodies against AI H9N2 by either HI or MN assays using ≥40 cut-off antibody titre. A total of 4.7% and 3.8% poultry workers were positive for antibodies against AI H9N2 by HI and MN assay respectively using 40 as cut-off antibody titre. This is the first report of seroprevalence of antibodies against AI H9N2 among poultry workers in India.

We describe a burn patient who developed skin lesions on her skin-graft harvest and skin-graft recipient (burn) sites. Orf virus infection was confirmed by a combination of diagnostic assays, including molecular tests, immunohistochemical analysis, pathologic analysis, and electron microscopy. DNA sequence analysis grouped this orf virus isolate among isolates from India. Although no definitive source of infection was determined from this case, this is the first reported case of orf virus infection in a skin graft harvest. Skin graft recipients with exposures to animals may be at risk for this viral infection. Published by Oxford University Press for the Infectious Diseases Society of America 2016.

Full Text Available Bluetongue (BT, peste des petits ruminants (PPR and sheep pox are the most economically important viral diseases of sheep in India. Serum samples obtained from sheep in five northern states of the country were screened for antibody against these agents to explore the extent of spread of these infections. A total of 516 serum samples were screened for the presence of antibodies against BT and PPR viruses. Of these, 155 samples were also tested for antibodies against sheep pox virus. BT antibodies were found in 293 (56.8% animals, PPR virus antibodies in 215 (41.7% and sheep pox virus antibodies in 106 (68.3%. Of the serum samples tested, 25.2% were positive for antibodies against all three viruses. These findings clearly demonstrated not only the enzootic nature of disease, but also the co-existence of antibodies to more than one of these viruses which would indicate that concurrent infections were common. Therefore, control measures should focus in combating all three diseases simultaneously by exploring the possibility of a trivalent vaccine or the use of multiple genes expressing vectored vaccine.

Rubella virus infection typically presents as a mild illness in children; however, infection during pregnancy may cause the birth of an infant with congenital rubella syndrome (CRS). As of February 2017, India began introducing rubella-containing vaccine (RCV) into the public-sector childhood vaccination programme. Low-level RCV coverage among children over several years can result in an increase in CRS incidence by increasing the average age of infection without sufficiently reducing rubella incidence. We evaluated the impact of RCV introduction on CRS incidence across India's heterogeneous demographic and epidemiological contexts. We used a deterministic age-structured model that reflects Indian states' rural and urban area-specific demography and vaccination coverage levels to simulate rubella dynamics and estimate CRS incidence with and without RCV introduction to the public sector. Our analysis suggests that current low-level private-sector vaccination has already slightly increased the burden of CRS in India. We additionally found that the effect of public-sector RCV introduction depends on the basic reproductive number, R 0, of rubella. If R 0 is five, a value empirically estimated from an array of settings, CRS incidence post-RCV introduction will likely decrease. However, if R 0 is seven or nine, some states may experience short-term or annual increases in CRS, even if a long-term total reduction in cases (30 years) is expected. Investment in population-based serological surveys and India's fever/rash surveillance system will be key to monitoring the success of the vaccination programme.

The cultural universe of urban, English-speaking middle class in India shows signs of growing inclusiveness as far as English is concerned. This phenomenon manifests itself in increasing forms of bilingualism (combination of English and one Indian language) in everyday forms of speech - advertisement jingles, bilingual movies, signboards, and of course conversations. It is also evident in the startling prominence of Indian Writing in English and somewhat less visibly, but steadily rising, activity of English translation from Indian languages. Since the eighties this has led to a frenetic activity around English translation in India's academic and literary circles. Kothari makes this very current phenomenon her chief concern in Translating India.   The study covers aspects such as the production, reception and marketability of English translation. Through an unusually multi-disciplinary approach, this study situates English translation in India amidst local and global debates on translation, representation an...

Nairobi sheep disease virus (NSDV; also called Ganjam virus in India) is a bunyavirus of the genus Nairovirus. It causes a haemorrhagic gastroenteritis in sheep and goats with mortality up to 90%. The virus is closely related to the human pathogen Crimean-Congo haemorrhagic fever virus (CCHFV). Little is currently known about the biology of NSDV. We have generated specific antibodies against the virus nucleocapsid protein (N) and polymerase (L) and used these to characterise NSDV in infected cells and to study its distribution during infection in a natural host. Due to its large size and the presence of a papain-like protease (the OTU-like domain) it has been suggested that the L protein of nairoviruses undergoes an autoproteolytic cleavage into polymerase and one or more accessory proteins. Specific antibodies which recognise either the N-terminus or the C-terminus of the NSDV L protein showed no evidence of L protein cleavage in NSDV-infected cells. Using the specific anti-N and anti-L antibodies, it was found that these viral proteins do not fully colocalise in infected cells; the N protein accumulated near the Golgi at early stages of infection while the L protein was distributed throughout the cytoplasm, further supporting the multifunctional nature of the L protein. These antibodies also allowed us to gain information about the organs and cell types targeted by the virus in vivo. We could detect NSDV in cryosections prepared from various tissues collected post-mortem from experimentally inoculated animals; the virus was found in the mucosal lining of the small and large intestine, in the lungs, and in mesenteric lymph nodes (MLN), where NSDV appeared to target monocytes and/or macrophages.

The 2009 A (H1N1) influenza virus pandemic: A review.

In March and early April 2009 a new swine-origin influenza virus (S-OIV), A (H1N1), emerged in Mexico and the USA. The virus quickly spread worldwide through human-to-human transmission. In view of the number of countries and communities which were reporting human cases, the World Health Organization raised the influenza pandemic alert to the highest level (level 6) on June 11, 2009. The propensity of the virus to primarily affect children, young adults and pregnant women, especially those with an underlying lung or cardiac disease condition, and the substantial increase in rate of hospitalizations, prompted the efforts of the pharmaceutical industry, including new manufacturers from China, Thailand, India and South America, to develop pandemic H1N1 influenza vaccines. All currently registered vaccines were tested for safety and immunogenicity in clinical trials on human volunteers. All were found to be safe and to elicit potentially protective antibody responses after the administration of a single dose of vaccine, including split inactivated vaccines with or without adjuvant, whole-virion vaccines and live-attenuated vaccines. The need for an increased surveillance of influenza virus circulation in swine is outlined. Copyright 2010. Published by Elsevier Ltd.

Preliminary findings on Bagaza virus (Flavivirus: Flaviviridae growth kinetics, transmission potential & transovarial transmission in three species of mosquitoes

2013-01-01

Full Text Available Background & objectives: Bagaza virus (BAGV, a flavivirus synonymous with Israel turkey meningoencephalitis virus, has been found to circulate in India. BAGV has recently been held responsible for inducing febrile illness in humans and causing unusually high mortality to wild birds in Spain. A study was therefore, undertaken to determine its replication kinetics in certain mosquitoes and to determine vector competence and potential of the mosquitoes to transmit BAGV experimentally. Methods: Aedes aegypti, Culex tritaeniorhynchus and Cx quinquefasciatus mosquitoes were inoculated with BAGV; samples were harvested every day and titrated in BHK-21 cell line. Vector competence and experimental transmission were determined by examining the saliva of infected mosquitoes for virus and induction of sickness in suckling mice, respectively. Results: Cx. tritaeniorhynchus and Ae. aegypti mosquitoes yielded 5 log 10 and 4.67 log 10 TCID 50 /ml of virus on day 3 post-infection (PI, respectively while Cx. quinquefasciatus yielded a titre of 4 log 10 TCID 50 /ml on day 4 PI. BAGV was detected in saliva of all the infected mosquitoes demonstrating their vector competence. Experimental transmission of BAGV to infant mice as well as transovarial transmission was demonstrated by Cx. tritaeniorhynchus but not by Ae. aegypti and Cx. quinquefasciatus mosquitoes. Interpretation & conclusions: Replication of BAGV to high titres and dissemination to saliva in three most prevalent mosquitoes in India is of immense public health importance. Though no major outbreak involving man has been reported yet, BAGV has a potential to cause outbreaks in future.

Interest has grown recently in the issues of third tier or emerging nuclear suppliers. These are states that could export nuclear equipment, services, or technology but are outside the export control framework of the London Nuclear Supplier Group (NSG). The concern is that they may conduct nuclear trade without adequate safeguards, thus weakening the nonproliferation regime or even contributing to nuclear proliferation. The volume of nuclear sales by emerging suppliers is still minuscule, and it is unclear how far their export practices will diverge from the NSG framework. This case study of Indian nuclear supplier capability and practice is an effort to discern the type of path India is likely to adopt. This paper examines four aspects of India's nuclear activity for clues to India's potential role as an emerging nuclear supplier: foreign transactions; nuclear decision making; policy norms; and nuclear industrial capabilities

Full Text Available Context: With anti-retroviral therapy (ART for human immunodeficiency virus infection (HIV coming into picture, quality of life (QOL has gained importance. Knowledge on the factors affecting QOL would be helpful in making important policy decisions and health care interventions. Aims: The aim of this study is to assess the quality of life of people living with HIV (PLWH and to identify the factors influencing their QOL. Materials and Methods: The study was done among 200 PLWH attending a tertiary care hospital, and three Non Governmental Organizations at Puducherry, India, from November 2005 to May 2007. QOL was assessed using HIV specific World Health Organization Quality Of Life scale (WHOQOL-HIV - BREF questionnaire which has six domains (physical, psychological, level of independence, social relationships, environment and spirituality/religiousness/personal belief. Social support and stigma were measured using "Multidimensional Scale of Perceived Social Support" and "HIV Stigma Scale," respectively, using Likert Scale. Factors influencing QOL were identified using backward stepwise multiple linear regression with the six domain scores as the dependent variables. Results: Male: Female ratio was 1:1 and 58% were in early stage of the disease (stage I/II. Psychological and SRPB (Spirituality Religiousness and Personal Beliefs domains were the most affected domains. All the regression models were statistically significant (P<0.05. The determination coefficient was highest for the social relationship domain (57% followed by the psychological domain (51%. Disease stage and perceived social support significantly influenced all the domains of WHOQOL. Younger age, female gender, rural background, shorter duration of HIV, non-intake of ART and greater HIV related stigma were the high risk factors of poor QOL. Conclusion: Interventions such as ART, family, vocational and peer counseling would address these modifiable factors influencing QOL, thereby

India is emerging as a strong force in the global economy. The population of China is 1.2 times that of India, and its gross domestic product is 2.5 times that of India. However, analyses of per capita gross domestic product (GDP) indicate that if India continues its rate of growth, its' consumption and production will reach China's current levels in less than 15 years. This represents a significant investment opportunity in basic industry, particularly since a growing middle class will ensure a boom in consumer products consumption. This presentation compared India and China, in terms of economic approaches and challenges for India. Implications for the petrochemical industry were also discussed with reference to Reliance Industries Ltd. and its full integration in the value chain with petroleum refining. Reliance Industries Ltd. claims that India's captive utilities and labour productivity provide the company with conversion costs that are among the lowest in the industry. In terms of agriculture, India is one of the largest producers of agricultural commodities in the world and is well supported by varying agro-climates and fertile land. This presentation also included an agro-commodities yield comparison for rice, wheat and cereal. The Indian manufacturing industry is also competitive, focusing on cutting cost, increasing productivity and innovation. It was noted that although China has the advantage of a well established infrastructure on a global and domestic scale as well as job opportunities and quick policy implementation, it has lax labour laws, poor pollution laws and a challenging banking system. In contrast, India has the entrepreneurial advantage as well as global scale information technology, a globally competitive manufacturing industry, an independent regulatory framework and world class capital markets and banking system. India's challenge lies in its lack of a world-class infrastructure, complicated tax structure and slow

To identify the distribution pattern of Hepatitis B Virus (HBV) genotype in a group of patients and to study its phylogenetic divergence. Two hundred and one HBV infected patients were genotyped for this study. All HbsAg positive individuals, either healthy carriers or suffering from conditions such as acute or chronic hepatitis, cirrhosis and hepatocellular carcinoma were included. Hepatitis B patients co-infected with other hepatic viruses were excluded. Hepatitis B virus DNA was extracted from serum, and subjected to a nested PCR, using the primers type-specific for genotype detection. Phylogenetic analysis was performed in the pre-S1 through S genes of HBV. The divergence was studied through 15 sequences of 967bp submitted to the DBJ/EMBL/GenBank databases accessible under accession number EF584640 through EF584654. Out of 201 patients tested, 156 were males and 45 were females. Genotype D was the predominant type found in 128 (64%) patients followed by A in 47 (23%) and mixed A/D in 26 (13%). Phylogenetic analysis confirmed the dominance of genotype D and subtype ayw2. There was dominance of genotype D subtype ayw2. It had a close resemblance with HBV strains that circulate in Iran, India and Japan. (author)

Hepatitis E virus (HEV) has two discrete epidemiological patterns: waterborne epidemics in developing countries only, caused by HEV genotype I, and sporadic zoonotic outbreaks in developing and developed countries caused by genotypes III and IV. This study was designed to investigate seroprevalence, molecular detection and the characterization of HEV by nested RT-PCR in swine as well as the occupational risk to exposed human population in Punjab state of north-western India. The occupational risk-exposed group comprised of swine farmers (organized - mixed feed feeders and unorganized - swill feeders), slaughterhouse workers, sewage workers and veterinary internes. During the study period, blood and faecal samples were collected from 320 swine and 360 humans with both high and low occupational exposure risks. The overall seroprevalence of swine HEV was 65.00%, with a significantly higher seropositivity in growing pigs (2-8 months of age). The prevalence of HEV RNA in swine faecal samples by nRT-PCR was 8.75% with a significantly higher detection in swill-fed pigs. With humans in the high occupational exposure risk population, significantly higher anti-HEV IgG seropositivity was observed (60.48%) as compared to control population (10.71%). Strong evidence of association between human anti-HEV IgG seropositivity and certain occupational exposure risk groups was observed (p workers and sewage workers have higher odds of HEV infection in this study region. Percentage of nucleotide similarity between swine and human HEV isolates was less than that found in countries with zoonotic HEV outbreaks. Molecular characterization revealed the circulation of G IV and G I genotypes among swine and human population in Punjab state, respectively. © 2017 Blackwell Verlag GmbH.

Human papilloma virus (HPV)-associated head and neck cancer (HNC) has generated significant amount of research interest in recent times with focus shifted to oral cavity squamous cell cancer (OCSCC) after oropharyngeal cancer. Due to high incidence of OCSCC and anecdotal reports on association of HPV infection from northern region of India, this study was conceived to investigate HPV infection and establish its association with lifestyle habits such as tobacco, alcohol consumption, oro-genital sex, number of sexual contacts, and change in quality of life posttreatment. A total of 43 primary OCSCC biopsy specimens were collected. These samples were analyzed for HPV DNA genotyping which was done by using 13 high-risk HPV real-time PCR kits. Quality of life was assessed using University of Washington questionnaire for HNC patients, which was administered pretreatment and 3-months posttreatment. HPV presence was confirmed in only three patients (7.0 %). HPV positivity did not find any statistical correlation with age, gender, residence, addiction habit, stage, tumor size, nodal status, tumor grade, and number of sexual contacts. There was no significant ( p  > 0.05) difference in the average percent change in QOL parameters from pretreatment to posttreatment when correlated with HPV status.

Both sheep and goat pox are contagious viral diseases and affect small ruminants and are caused by sheep pox virus and goat pox virus respectively that belong to genus Capripoxvirus of Poxviridae family. Huge economic losses emanating from the disease outbreaks are the results of the wool and hide damage, subsequent production losses and also the morbidities and mortalities associated with the disease. This communication highlights clinico-epidemiological observations from the two sheep pox and one goat pox outbreaks. Grossly, multisystemic nodular lesions, mucopurulent nasal discharges and respiratory symptoms were observed in the affected animals. The morbidity, mortality and case fatality rates were 5.18%, 2.45% and 32.37%, respectively. Histopathological, haematological, molecular and serological techniques and also isolation of virus in embryonated chicken eggs were used for the diagnosis of the diseases. The spatial distribution of the disease signifies the role of common pasturelands used for grazing the animals while temporally all three outbreaks occurred in winters and were probably associated with cold stress and fodder scarcity. This is the first recorded report of Capripoxvirus infection in recent times and it highlights the disease as one of the emerging diseases in the northern state of Himachal Pradesh in India. © 2010 Blackwell Verlag GmbH.

Full Text Available Background & objectives: The reports from the countries where mumps vaccine is given as routine immunization suggest differences in mumps virus neutralizing antibody titres when tested with vaccine and wild type viruses. Such reports are unavailable from countries like India where mumps vaccine is not included in routine immunization. We, therefore, undertook this study to understand the cross-neutralization activity of Indian mumps viruses. Methods: By using commercial mumps IgG enzyme immunoassay (EIA and a rapid focus reduction neutralization test (FRNT, a panel of serum samples was tested. The panel consisted of 14 acute and 14 convalescent serum samples collected during a mumps outbreak and 18 archived serum samples. Two wild types (genotypes C and G and Leningrad-Zagreb vaccine strain (genotype N were used for the challenge experiments and FRNT titres were determined and further compared. The HN protein sequence of three mumps viruses was analyzed for the presence of key epitopes. Results: All serum samples effectively neutralized mumps virus wild types and a vaccine strain. However, significantly lower FRNT titres were noted to wild types than to vaccine strain (P<0.05. The comparison between EIA and FRNT results revealed 95.6 per cent agreement. No amino acid changes were seen in the epitopes in the Indian wild type strains. All potential N-linked glycosylation sites were observed in Indian strains. Interpretation & conclusions:Good cross-neutralization activity was observed for three mumps virus strains, however, higher level of FRNT titres was detected for mumps virus vaccine strain compared to Indian wild type isolates.

India has an economic growth between 8 to 10 % by year. To become a great country of the twenty first century and to stop poverty it is necessary to keep this growth but the growth of India is dependant of its ability to supply electric power necessary to increase the industrial production. The country has to multiply by four its energy production. The electric production comes from thermal power plants for 65%, 26% from hydroelectric power plants, 6% from renewable energy sources and 3% from nuclear energy. Between solar energy ( India has three hundred solar days by years) and nuclear energy using thorium that can be increased India has to choose an energy policy to answer its energy demand and independence need.

Oral squamous cell carcinoma (OSCC) is a major health problem in many parts of the world, and the major causative agents are thought to be the use of alcohol and tobacco. Oncogenic viruses have also been suggested to be involved in OSCC development. This study investigated the prevalence of human papillomaviruses (HPV), herpes simplex virus (HSV) and Epstein-Barr virus (EBV) in 155 OSCC from eight different countries from different ethnic groups, continents and with different socioeconomic backgrounds. 41 A total of OSCCs were diagnosed in the tongue (26%) and 23 in the floor of the mouth (15%); the other 91 OSCCs were diagnosed in other locations (59%). The patients were also investigated regarding the use of alcohol and smoking and smokeless tobacco habits. Tissue samples were obtained from formalin-fixed, paraffin-embedded samples of the OSCC. DNA was extracted and the viral genome was examined by single, nested and semi-nested PCR assays. Sequencing of double-stranded DNA from the PCR product was carried out. Following sequencing of the HPV-, HSV- and EBV-positive PCR products, 100% homology between the sampels was found. Of all the 155 OSCCs examined, 85 (55%) were positive for EBV, 54 (35%) for HPV and 24 (15%) for HSV. The highest prevalence of HPV was seen in Sudan (65%), while HSV (55%) and EBV (80%) were most prevalent in the UK. In 34% (52/155) of all the samples examined, co-infection by two (46/155=30%) or three (6/155=4%) virus specimens was detected. The most frequent double infection was HPV with EBV in 21% (32/155) of all OSCCs. There was a statistically significant higher proportion of samples with HSV (p=0.026) and EBV (p=0.015) in industrialized countries (Sweden, Norway, UK and USA) as compared to developing countries (Sudan, India, Sri Lanka and Yemen). Furthermore, there was a statistically significant higher co-infection of HSV and EBV in samples from industrialized countries (p=0.00031). No firm conclusions could be drawn regarding the

Full Text Available Nairobi sheep disease virus (NSDV; also called Ganjam virus in India is a bunyavirus of the genus Nairovirus. It causes a haemorrhagic gastroenteritis in sheep and goats with mortality up to 90%. The virus is closely related to the human pathogen Crimean-Congo haemorrhagic fever virus (CCHFV. Little is currently known about the biology of NSDV. We have generated specific antibodies against the virus nucleocapsid protein (N and polymerase (L and used these to characterise NSDV in infected cells and to study its distribution during infection in a natural host. Due to its large size and the presence of a papain-like protease (the OTU-like domain it has been suggested that the L protein of nairoviruses undergoes an autoproteolytic cleavage into polymerase and one or more accessory proteins. Specific antibodies which recognise either the N-terminus or the C-terminus of the NSDV L protein showed no evidence of L protein cleavage in NSDV-infected cells. Using the specific anti-N and anti-L antibodies, it was found that these viral proteins do not fully colocalise in infected cells; the N protein accumulated near the Golgi at early stages of infection while the L protein was distributed throughout the cytoplasm, further supporting the multifunctional nature of the L protein. These antibodies also allowed us to gain information about the organs and cell types targeted by the virus in vivo. We could detect NSDV in cryosections prepared from various tissues collected post-mortem from experimentally inoculated animals; the virus was found in the mucosal lining of the small and large intestine, in the lungs, and in mesenteric lymph nodes (MLN, where NSDV appeared to target monocytes and/or macrophages.

The small ruminant lentiviruses are known to cause maedi-visna (MV) and caprine arthritis - encephalitis in sheep and goats, typically affecting joints, udder, lungs, and the central nervous system. The diagnosis usually involves serology, clinical signs, immunohistochemistry, and polymerase chain reaction (PCR). In the present study, the histopathologically positive pneumonia cases of MV were confirmed by PCR in lung tissue probably for the first time in India. A total of 888 lungs of adult sheep, aged between 2 and 5 years, were screened during slaughter, of which 121 were found to have pneumonic lesions. The tissues from each pneumonic lung including associated lymph nodes were collected in 10% neutral buffered formalin for histopathology. The frozen tissues of the same were also collected and stored at -20°C for PCR confirmation. Three of 121 cases of pneumonic lungs of sheep revealed gross and histopathological lesions suggestive of maedi or ovine progressive pneumonia infection. These 3 cases were further confirmed by PCR technique that amplified 291-base pair DNA in the long terminal repeat sequence of MV provirus. This study suggests the low occurrence of MV virus (MVV) infection in India in naturally affected sheep based on pathomorphological lesions and using the molecular tool of PCR detection of the virus in tissues. Further, a combination of pathomorphology or/and PCR testing might be optimal for detecting the animals infected with MVV.

Natural Gas Exploration and Supply in India and the Prospects of a Bangladesh-to-India Pipeline

Energy consumption in India is growing very rapidly. India.s own existing as well as any new discoveries of natural gas revenues may meet only a fraction of its growing demand for energy. Hence, it will become more dependent on the global market for the supply of gas. But it is always difficult for different nations to reach a bilateral agreement on joint projects such as gas pipelines. India has been importing natural gas mostly in the form of Liquefied Natural Gas (LNG). But for the last two decades, it has shown an increasing interest in importing gas from international market by a pipeline. For example, it has planned to import natural gas from Iran, Myanmar, Bangladesh, and Turkmenistan via a pipeline. But India.s best option is to purchase gas from its neighbor Bangladesh via a pipeline. Union Oil of California (Unocal), a large investor in Bangladeshi gas, has proposed to build a pipeline, to sell the gas from its Bibiyana field. A Bangladesh-India pipeline potentially offers several socio-economic benefits. But the project, however, so far has made a little progress. Political issues attached to the project. If the Bangladeshi pipeline plan fails, India will turn other alternative options to meet its gas demand. India already has entered into agreement with International consortiums for LNG purchase. Furthermore, the country is also keen on increasing its effort to develop non-conventional sources in the near future. If these alternatives become viable, India.s demand for and dependence on foreign natural gas will decrease and natural gas (of Bangladesh, for example) might lose some of its value. Keywords: Natural gas exploration and supply in India and Bangladesh, Bangladesh-to-India pipeline, Unocal, natural gas import, market, politics, LNG, non-conventional hydrocarbon sources.

Thirty-four suspected rabid brain samples from 2 humans, 24 dogs, 4 cats, 2 mongooses, I jackal and I water buffalo were collected in 1995-1996 in Sri Lanka. Total RNA was extracted directly from brain suspensions and examined using a one-step reverse transcription-polymerase chain reaction (RT-PCR) for the rabies virus nucleoprotein (N) gene. Twenty-eight samples were found positive for the virus N gene by RT-PCR and also for the virus antigens by fluorescent antibody (FA) test. Rabies virus isolates obtained from different animal species in different regions of Sri Lanka were genetically homogenous. Sequences of 203 nucleotides (nt)-long RT-PCR products obtained from 16 of 27 samples were found identical. Sequences of 1350 nt of N genes of 14 RT-PCR products were determined. The Sri Lanka isolates under study formed a specific cluster that included also an earlier isolate from India but did not include the known isolates from China, Thailand, Malaysia, Israel, Iran, Oman, Saudi Arabia, Russia, Nepal, Philippines, Japan and from several other countries. These results suggest that one type of rabies virus is circulating among human, dog, cat, mongoose, jackal and water buffalo living near Colombo City and in other five remote regions in Sri Lanka.

Tuberculosis (TB) hospital in Mumbai, India. To describe the mobility patterns of persons with suspected drug-resistant tuberculosis (DR-TB) and to assess whether there were significant differences in demographic or risk characteristics based on mobility. Observational cohort study of TB clinic patients at risk for DR-TB. Among 602 participants, 37% had ever moved from their place of birth; 14% were local movers (within state), and 23% were distant movers, between states or countries. Univariate multinomial logistic regression models showed that distant movers were more likely than non-movers to have lower income, less education, a greater number of previous TB episodes, and to have ever smoked. Compared to non-movers, local movers were more likely to have lower income and were more likely to have seen a doctor in the past 2 years. Clinical outcomes, including DR-TB, diabetes, and human immunodeficiency virus (HIV), did not differ between the three mobility groups. Mobility was common among patients at risk for DR-TB in Mumbai. TB programs should consider the implications of mobility on the protracted treatment for DR-TB in India.

Full Text Available Physical inactivity is the fourth leading risk factor for global mortality, with most of these deaths occurring in low and middle-income countries (LMICs like India. Research from developed countries has consistently demonstrated associations between built environment features and physical activity levels of populations. The development of culturally sensitive and reliable measures of the built environment is a necessary first step for accurate analysis of environmental correlates of physical activity in LMICs. This study systematically adapted the Neighborhood Environment Walkability Scale (NEWS for India and evaluated aspects of test-retest reliability of the adapted version among Indian adults. Cultural adaptation of the NEWS was conducted by Indian and international experts. Semi-structured interviews were conducted with local residents and key informants in the city of Chennai, India. At baseline, participants (N = 370; female = 47.2% from Chennai completed the adapted NEWS-India surveys on perceived residential density, land use mix-diversity, land use mix-access, street connectivity, infrastructure and safety for walking and cycling, aesthetics, traffic safety, and safety from crime. NEWS-India was administered for a second time to consenting participants (N = 62; female = 53.2% with a gap of 2–3 weeks between successive administrations. Qualitative findings demonstrated that built environment barriers and constraints to active commuting and physical activity behaviors intersected with social ecological systems. The adapted NEWS subscales had moderate to high test-retest reliability (ICC range 0.48–0.99. The NEWS-India demonstrated acceptable measurement properties among Indian adults and may be a useful tool for evaluation of built environment attributes in India. Further adaptation and evaluation in rural and suburban settings in India is essential to create a version that could be used throughout India.

Nuclear policy for India

Kaushik, B.M.

1977-01-01

Changes in India's nuclear policy from time to time are discussed. Though firmly wedded to the principle of peaceful uses of nuclear energy, India did not sign in 1965 the NPT as it discriminated between nuclear weapons powers and non-nuclear weapon powers as regards the safeguards. India wanted to keep open the option of conducting peaceful nuclear explosions (PNEs). In May 1974, India did conduct a PNE which, however, resulted into the stoppage of Canadian aid for India's nuclear power programme and created difficulties in obtaining enriched uranium for the Tarapur Atomic Power Station from the U.S.. The new Indian Government formed after the March 1977 general electtions has endorsed the earlier government's policy of opposing manufacture of nuclear weapons and has gone a step further by declearing 'If it (PNE) not necessary it should never be done'.

Bai, Xinghua

India and China are both featured with ancient civilization. During the communication between the two countries, the communication from Indian culture, especially Buddhism, to China was predominant, while communication from Chinese culture to India was rare. So it was with medical communication until the end of 1950s when acupuncture was introduced to India. In this article, the medical communication between India and China as well as the introduction of acupuncture to India were discussed, and the resulting phenomenon was analyzed. The introduction of acupuncture to India proved personnel exchange was not necessary to acupuncture communication, and several invisible factors, such as language, religion and culture tradition might be the reasons for foreign nations to accept acupuncture. Therefore, these factors should be valued in the future international communication of acupuncture.

The nuclear weapons and ballistic missile tests conducted by India and Pakistan in the late 1990s substantially altered the security environment, both in the region and globally. Examining the complexities, and dynamics of this new strategic context, this timely and significant book examines the claim of many Indian strategists that stability in the region is better served under conditions of declared-rather than covertly developed-nuclear weapons. Bringing together original essays by a diverse group of scholars, this volume discusses a number of important issues such as: the political considerations that caused India and Pakistan to go nuclear; the type of nuclear doctrine that is likely to emerge and its implications for the safety of nuclear weapons, the potential for an arms race in the region, and the likelihood of war; the political and economic consequences for India after Pokhran-II and the impact of economic sanctions; the technological ramifications of the nuclear program on India's defence science scenario; the impact of these tests on the future of India's relationship with the United States, the main bulwark against nuclear weapons proliferation, also, the changed role that India sees for itself in international fora; the possible arms control measures that might succeed in stabilizing the South Asian nuclear rivalry. This insightful, comprehensive and topical volume is a must-read for all those in the fields of political science, international relations, strategic affairs, conflict/peace studies, economics, and policy studies

Rabies is a fatal encephalitis caused by viruses belonging to the genus Lyssavirus of the family Rhabdoviridae. It is a viral disease primarily affecting mammals, though all warm blooded animals are susceptible. Experimental rabies virus infection in birds has been reported, but naturally occurring infection of birds has been documented very rarely. The carcass of a domestic fowl (Gallus domesticus), which had been bitten by a stray dog one month back, was brought to the rabies diagnostic laboratory. A necropsy was performed and the brain tissue obtained was subjected to laboratory tests for rabies. The brain tissue was positive for rabies viral antigens by fluorescent antibody test (FAT) confirming a diagnosis of rabies. Phylogenetic analysis based on nucleoprotein gene sequencing revealed that the rabies virus strain from the domestic fowl belonged to a distinct and relatively rare Indian subcontinent lineage. This case of naturally acquired rabies infection in a bird species, Gallus domesticus, being reported for the first time in India, was identified from an area which has a significant stray dog population and is highly endemic for canine rabies. It indicates that spill over of infection even to an unusual host is possible in highly endemic areas. Lack of any clinical signs, and fewer opportunities for diagnostic laboratory testing of suspected rabies in birds, may be the reason for disease in these species being undiagnosed and probably under-reported. Butchering and handling of rabies virus- infected poultry may pose a potential exposure risk.

India made an early commitment to being as self-sufficient as possible in nuclear energy and has largely achieved that goal. The country operates eight nuclear reactors with a total capacity of 1,304 MWe, and it remains committed to an aggressive growth plan for its nuclear industry, with six reactors currently under construction, and as many as twelve more planned. India also operates several heavy water production facilities, fabrication facilities, reprocessing works, and uranium mines and mills. Due to India's decision not to sign the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), the country has had to develop nearly all of its nuclear industry and infrastructure domestically. Overall, India's nuclear power program is self-contained and well integrated, with plans to expand to provide up to ten percent of the country's electrical generating capacity

Nonhuman Primate Models of Chikungunya Virus Infection and Disease (CHIKV NHP Model

Full Text Available Chikungunya virus (CHIKV is a positive-sense RNA virus transmitted by Aedes mosquitoes. CHIKV is a reemerging Alphavirus that causes acute febrile illness and severe and debilitating polyarthralgia of the peripheral joints. Huge epidemics and the rapid spread of CHIKV seen in India and the Indian Ocean region established CHIKV as a global health concern. This concern was further solidified by the recent incursion of the virus into the Western hemisphere, a region without pre-existing immunity. Nonhuman primates (NHPs serve as excellent animal models for understanding CHIKV pathogenesis and pre-clinical assessment of vaccines and therapeutics. NHPs present advantages over rodent models because they are a natural amplification host for CHIKV and they share significant genetic and physiological homology with humans. CHIKV infection in NHPs results in acute fever, rash, viremia and production of type I interferon. NHPs develop CHIKV-specific B and T-cells, generating neutralizing antibodies and CHIKV-specific CD4+ and CD8+ T-cells. CHIKV establishes a persistent infection in NHPs, particularly in cynomolgus macaques, because infectious virus could be recovered from spleen, liver, and muscle as late as 44 days post infection. NHPs are valuable models that are useful in preclinical testing of vaccines and therapeutics and uncovering the details of CHIKV pathogenesis.

Human polyomavirus JC (JCV) is a widespread human virus with profound pathogenic potential. A study was undertaken to quantify JCV load in urine and peripheral blood samples of immunocompetent, apparently healthy tribal individuals of North-Eastern part of West Bengal, India for the first time. One hundred and thirteen samples of urine or blood were collected from different tribal groups of this region. For the quantitative estimation of the viral load in each sample, real-time polymerase chain reaction method using the SYBR Green dye was employed. The viral load estimated was found in the range between 3.5 × 102 and 2.12 × 106 copies/ml of samples having a mean and median viral copy numbers of 8.67 × 105 and 9.19 × 105 copies/ml of sample respectively. The mean viral DNA load in urine samples of the studied immunocompetent population was found to be higher than that found in a study conducted in the USA, but lower than similar groups of Italy and healthy adult women in the USA. However when compared with median values of viral DNA loads in urine samples of immunocompetent human subjects of Kuwait, Portugal, and Switzerland the observed viral DNA load was found to be substantially higher.

Pandemic influenza A (H1N1) 2009 virus was first detected in India in May 2009 which subsequently became endemic in many parts of the country. Influenza A viruses have the ability to evade the immune response through its ability of antigenic variations. The study aims to characterize influenza A (H1N1) pdm 09 viruses circulating in Mumbai during the pandemic and post-pandemic period. Nasopharyngeal swabs positive for influenza A (H1N1) pdm 09 viruses were inoculated on Madin-Darby canine kidney cell line for virus isolation. Molecular and phylogenetic analysis of influenza A (H1N1) pdm 09 isolates was conducted to understand the evolution and genetic diversity of the strains. Nucleotide and amino acid sequences of the HA gene of Mumbai isolates when compared to A/California/07/2009-vaccine strain revealed 14 specific amino acid differences located at the antigenic sites. Amino acid variations in HA and NA gene resulted in changes in the N-linked glycosylation motif which may lead to immune evasion. Phylogenetic analysis of the isolates revealed their evolutionary position with vaccine strain A/California/07/2009 but had undergone changes gradually. The findings in the present study confirm genetic variability of influenza viruses and highlight the importance of continuous surveillance during influenza outbreaks.

In the decades following India's independence from British rule in 1947, the West's image of India was summarized in three simple cliches: the world's largest democracy, an impoverished continent, and economic growth hampered by a fussy bureaucracy and the caste system, all in a context of a particular religion. These cliches are perhaps one of the reasons that the success of India's green revolution was recognized so late, a revolution that allowed the country to develop its agricultural sector and to feed its population. Since the 1990's, the easing of planning constraints have liberated the Indian economy and allowed it to embark on a more significant path of growth. New cliches have begun to replace the old: India will become a second China and, lagging by 10 to 20 years, will follow the same trajectory, with its development marked more by services and the use of renewable energy. However, these trends will not prevent primary energy demand from exploding. On the contrary, India faces difficult choices on how it increases clean, secure, affordable energy to all its citizens. Many of the choices are the same as found elsewhere, but on a scale matched only by China. The IFRI European Governance and Geopolitics of Energy Project intends this study to deepen public understanding of the magnitude of India's challenges. Various aspects of the serious energy problems are studied throughout this monograph. The authors have written freely on these matters without attempting to reconcile their different viewpoints. The first chapter, by Maite Jaureguy-Naudin and Jacques Lesourne, presents an overview of India's present and future energy system. The authors follow a prudent but realistic view of India's future. The second chapter, by Jean-Joseph Boillot, a French expert on India who has published several books and articles on this subject, and Nicolas Autheman, research fellow, describes in greater detail the specifics of India's economy and the actors who are now present

Full Text Available Kyasanur Forest Disease Virus (KFDV, discovered in 1957, is a member of the tick-borne encephalitis virus (TBEV complex. Diseases caused by members of the TBEV complex occur in many parts of the world. KFDV produces a hemorrhagic fever in humans in South India and fatal illnesses in both species of monkeys in the area, the black faced langur (Presbytis entellus and the bonnet macaque (Macaca radiata. Experimental infection of the langur and the bonnet macaque with early mouse passage KFDV strain P9605 resulted in a viremia of up to 11 days duration, peak viremia titers as high as 109, and death in 82 = 100% of the animals. Prolonged passage of the KFDV strain P9605 in monkey kidney tissue culture resulted in a markedly reduced virulence of the virus for both species; peak viremia titers in monkeys decreased by 2.5 to 4.0 log LD 50 (p= 0.001, and the mortality decreased to 10% (p= 0.001. In challenge experiments, monkeys previously infected with tissue-culture-adapted KFDV, or with the related Langat virus from Malaysia, were fully protected against virulent KFDV. These studies in non-human primates lend support to the idea that a live virus vaccine from a member of the TBEV complex may be broadly protective against infections by other members of the TBEV complex.

2017-10-01

Full Text Available Introduction: Hepatitis A Virus (HAV and Hepatitis E Virus (HEV pose major health problems in India. Both viruses are enterically transmitted, resulting in Acute Viral Hepatitis (AVH in developing countries. This study was done to determine prevalence of HAV and HEV and their co-infection in patients presenting with AVH in a tertiary care hospital. Aim: To determine the prevalence of HAV and HEV and their co-infection among patients attending a Tertiary Care Hospital in Jodhpur presenting with symptoms of acute hepatitis. Materials and Methods: A cross-sectional study of one year duration was conducted in the Department of Microbiology, Dr S.N. Medical College, Jodhpur. A non random sampling of 174 patients presenting with AVH was considered in the study. On the basis of history, serum samples were analyzed for IgM anti-HAV and IgM anti-HEV for the detection of HAV and HEV, respectively using commercially available ELISA kits. Data collected was analysed by using Statistical Package for the Social Sciences (SPSS version 11 and p-value <0.05 was considered significant. Results: The seroprevalence of HAV and HEV positive patients were 13.79% and 4.02%, respectively. The seroprevalence of both HAV and HEV in patients with AVH was 1.15%. The prevalence of HAV and HEV among males (58.3% and 41.6% was higher than in females (7.97% and 14.28%. Conclusion: The prevalence of HAV is higher than that of HEV but screening of HEV should be done as there are cases of coinfections. In this region of country, these data will play a role in planning of vaccination strategies and for better sanitation programme in future.

Tropospheric aerosol optical depth (AOD) over India was simulated by Goddard Earth Observing System (GEOS)-Chem, a global 3-D chemical-transport model, using SMOG (Speciated Multi-pOllutant Generator from Indian Institute of Technology Bombay) and GEOS-Chem (GC) (current inventories used in the GEOS-Chem model) inventories for 2012. The simulated AODs were 80% (SMOG) and 60% (GC) of those measured by the satellites (Moderate Resolution Imaging Spectroradiometer and Multi-angle Imaging SpectroRadiometer). There is no strong seasonal variation in AOD over India. The peak AOD values are observed/simulated during summer. The simulated AOD using SMOG inventory has particulate black and organic carbon AOD higher by a factor 5 and 3, respectively, compared to GC inventory. The model underpredicted coarse-mode AOD but agreed for fine-mode AOD with Aerosol Robotic Network data. It captured dust only over Western India, which is a desert, and not elsewhere, probably due to inaccurate dust transport and/or noninclusion of other dust sources. The calculated AOD, after dust correction, showed the general features in its observed spatial variation. Highest AOD values were observed over the Indo-Gangetic Plain followed by Central and Southern India with lowest values in Northern India. Transport of aerosols from Indo-Gangetic Plain and Central India into Eastern India, where emissions are low, is significant. The major contributors to total AOD over India are inorganic aerosol (41-64%), organic carbon (14-26%), and dust (7-32%). AOD over most regions of India is a factor of 5 or higher than over the United States.

The Indian government has published (in Hydrocarbon Vision 2025) its ideas for a long term strategy for its oil industry which is currently growing at an unprecedented rate. Increasing domestic production and investment in oil exploration and production overseas figure strongly in the plan. At present, India has a refining surplus but with an annual growth of 8-10%, this will disappear in the next 2-3 years. The report recommends that India should maintain 90% self-sufficiency in refining. The report sees development of the domestic oil industry as globally competitive and helping safeguard India's assets. The capability of India's refineries, current upgrading, the newer refineries and plans for new projects are all mentioned

Novel genotypes of H9N2 influenza A viruses isolated from poultry in Pakistan containing NS genes similar to highly pathogenic H7N3 and H5N1 viruses.

Full Text Available The impact of avian influenza caused by H9N2 viruses in Pakistan is now significantly more severe than in previous years. Since all gene segments contribute towards the virulence of avian influenza virus, it was imperative to investigate the molecular features and genetic relationships of H9N2 viruses prevalent in this region. Analysis of the gene sequences of all eight RNA segments from 12 viruses isolated between 2005 and 2008 was undertaken. The hemagglutinin (HA sequences of all isolates were closely related to H9N2 viruses isolated from Iran between 2004 and 2007 and contained leucine instead of glutamine at position 226 in the receptor binding pocket, a recognised marker for the recognition of sialic acids linked alpha2-6 to galactose. The neuraminidase (NA of two isolates contained a unique five residue deletion in the stalk (from residues 80 to 84, a possible indication of greater adaptation of these viruses to the chicken host. The HA, NA, nucleoprotein (NP, and matrix (M genes showed close identity with H9N2 viruses isolated during 1999 in Pakistan and clustered in the A/Quail/Hong Kong/G1/97 virus lineage. In contrast, the polymerase genes clustered with H9N2 viruses from India, Iran and Dubai. The NS gene segment showed greater genetic diversity and shared a high level of similarity with NS genes from either H5 or H7 subtypes rather than with established H9N2 Eurasian lineages. These results indicate that during recent years the H9N2 viruses have undergone extensive genetic reassortment which has led to the generation of H9N2 viruses of novel genotypes in the Indian sub-continent. The novel genotypes of H9N2 viruses may play a role in the increased problems observed by H9N2 to poultry and reinforce the continued need to monitor H9N2 infections for their zoonotic potential.

India's Research Contributions Towards Polio Eradication (1965-2015).

Pioneering research has been conducted in India during the past five decades, comprehensively covering epidemiology of poliovirus infection and of polio, efficacy and effectiveness of oral and inactivated polio vaccines (OPV, IPV) as well as pathogenesis of wild and vaccine polioviruses. It was estimated, based on epidemiology data, that India had a very heavy burden of polio, with average 500-1000 cases per day. Prevention was an urgent need, but OPV showed unacceptably low vaccine efficacy (VE) for poliovirus types 1 and 3. Having learned that response to sequential doses followed arithmetic pattern and not prime-boost principle, multiple doses were tested and found to be a simple intervention to increase VE. Eventually this knowledge became critical for polio eradication. Indian research demonstrated that monovalent OPV (mOPV) had nearly three timed higher VE than trivalent OPV (tOPV). Eventually, mOPV type 1 became essential to interrupt wild type 1 infection in many locations where the VE of tOPV was very low. Indian research pointed to the epidemiologic importance of direct person-to-person spread of wild polio viruses and the need and potential of IPV to prevent and control polio. Research on vaccine responses led to the understanding that OPV would become wild-like through back mutations and to the definition of eradication as interrupting transmission of both wild and vaccine-derived polioviruses. By asking and answering the right questions insequence, Indian polio research presaged and guided polio eradication.

Role of India's wildlife in the emergence and re-emergence of zoonotic pathogens, risk factors and public health implications.

Evolving land use practices have led to an increase in interactions at the human/wildlife interface. The presence and poor knowledge of zoonotic pathogens in India's wildlife and the occurrence of enormous human populations interfacing with, and critically linked to, forest ecosystems warrant attention. Factors such as diverse migratory bird populations, climate change, expanding human population and shrinking wildlife habitats play a significant role in the emergence and re-emergence of zoonotic pathogens from India's wildlife. The introduction of a novel Kyasanur forest disease virus (family flaviviridae) into human populations in 1957 and subsequent occurrence of seasonal outbreaks illustrate the key role that India's wild animals play in the emergence and reemergence of zoonotic pathogens. Other high priority zoonotic diseases of wildlife origin which could affect both livestock and humans include influenza, Nipah, Japanese encephalitis, rabies, plague, leptospirosis, anthrax and leishmaniasis. Continuous monitoring of India's extensively diverse and dispersed wildlife is challenging, but their use as indicators should facilitate efficient and rapid disease-outbreak response across the region and occasionally the globe. Defining and prioritizing research on zoonotic pathogens in wildlife are essential, particularly in a multidisciplinary one-world one-health approach which includes human and veterinary medical studies at the wildlife-livestock-human interfaces. This review indicates that wild animals play an important role in the emergence and re-emergence of zoonotic pathogens and provides brief summaries of the zoonotic diseases that have occurred in wild animals in India.

@@ It would be impossible to understand India without any knowledge about the religions of this country. India is a developing country with many religions, nationalities and languages. This nation has long been noted for its democratic politics and multiculture. India was founded on the principle of secularism, but at the same time it has suffered from religions. Therefore, to have a clear idea about the basic conditions of India's multiple religious beliefs is the foundation for studies of its religions of the country, and is also one key to grasping Indian social politics. In early September 2004, the Indian government published religious data from the 2001 census. Accordingly, we can make some basic judgments about the religions in today's India.

India: nuclear policy, opportunities and challenges

From the policy point of view, India nuclear scenario can be classified into three phases. During the first phase lasting between 1947 (the time of India independence) and 1974 (when India conducted the first nuclear test), India emphasized the peaceful use of nuclear energy. Many developed countries including the countries of NATO (North Atlantic Treaty Organization) including the USA, the Canada and France apart from the erstwhile USSR (Union of Soviet Socialist Republic) cooperated with India in the construction of Nuclear power reactors, supply of Fuel and providing technical knowledge. This cooperation lasted for about 27 years from 1947 and 1974. During the second phase lasting between 1974 (the time when India conducted the first nuclear test for military purpose) and 2008 (when Indian Parliament ratified the Indo-US Nuclear Deal), India refused to sign the CTBT (Comprehensive Nuclear Test Ban Treaty) and reserved the right to use nuclear energy for military purpose. Indian insecurity was due to the presence of China - a nuclear power in the neighbourhood, the high probability of Pakistan - another neighbour Becoming the nuclear power and the unwillingness of the major nuclear powers : viz : the USA and USSR to provide a nuclear umbrella to India. The phase was marked by nuclear sanctions imposed against India by the US and the non cooperation from the nuclear powers in building nuclear power reactors and dissemination of technical knowledge. The phase did however lead to India efforts towards self reliance in nuclear technology and the advancement of knowledge leading to the construction of FBR (Fast Breeder Reactors) and the possibility of fructifying the Thorium based reactors. The third and present phase from the year 2008 when Indian Parliament ratified the Indo-US Nuclear deal symbolizes the recognition of India's Scientific and technological Prowess by major nuclear powers, the benefits of India knowledge to the world and realization of the fact that

Full Text Available Aim: The small ruminant lentiviruses are known to cause maedi-visna (MV and caprine arthritis - encephalitis in sheep and goats, typically affecting joints, udder, lungs, and the central nervous system. The diagnosis usually involves serology, clinical signs, immunohistochemistry, and polymerase chain reaction (PCR. In the present study, the histopathologically positive pneumonia cases of MV were confirmed by PCR in lung tissue probably for the first time in India. Materials and Methods: A total of 888 lungs of adult sheep, aged between 2 and 5 years, were screened during slaughter, of which 121 were found to have pneumonic lesions. The tissues from each pneumonic lung including associated lymph nodes were collected in 10% neutral buffered formalin for histopathology. The frozen tissues of the same were also collected and stored at -20°C for PCR confirmation. Results: Three of 121 cases of pneumonic lungs of sheep revealed gross and histopathological lesions suggestive of maedi or ovine progressive pneumonia infection. These 3 cases were further confirmed by PCR technique that amplified 291-base pair DNA in the long terminal repeat sequence of MV provirus. Conclusion: This study suggests the low occurrence of MV virus (MVV infection in India in naturally affected sheep based on pathomorphological lesions and using the molecular tool of PCR detection of the virus in tissues. Further, a combination of pathomorphology or/and PCR testing might be optimal for detecting the animals infected with MVV.

Reassortant influenza A viruses bearing the H1 subtype of hemagglutinin (HA) and the N2 subtype of neuraminidase (NA) were isolated from humans in the United States, Canada, Singapore, Malaysia, India, Oman, Egypt, and several countries in Europe during the 2001-2002 influenza season. The HAs of these H1N2 viruses were similar to that of the A/New Caledonia/20/99(H1N1) vaccine strain both antigenically and genetically, and the NAs were antigenically and genetically related to those of recent human H3N2 reference strains, such as A/Moscow/10/99(H3N2). All 6 internal genes of the H1N2 reassortants examined originated from an H3N2 virus. This article documents the first widespread circulation of H1N2 reassortants on 4 continents. The current influenza vaccine is expected to provide good protection against H1N2 viruses, because it contains the A/New Caledonia/20/99(H1N1) and A/Moscow/10/99(H3N2)-like viruses, which have H1 and N2 antigens that are similar to those of recent H1N2 viruses.

Full Text Available Background: The spread of Zika virus is of great concern as it is recently becoming the third global infectious disease outburst after H1N1 flu and the Ebola virus infections. Centre for Disease Control (CDC categorized Pakistan, India, and Bangladesh as countries vulnerable to Zika Risk. Realizing health implications of this emerging epidemic, it is a dire need to build an all-inclusive view of the status of research on Zika virus disease, and a lucid picture of the research output and scientific collaborations in the field. Methods: All the articles published globally on Zika virus during 2008-2017 and documented in Web of Science were analyzed using Microsoft Excel and Word Cloud tool. The data were extracted from all databases of the Web of Science, obtaining a total of 3384 articles for analysis. Results: 3384 records on Zika virus research were indexed in the Web of Science database during 2008-2017. The retrieved data indicate that over the past ten years, not much research has been done on this virus and the focus shifted to research on Zika in the last three years only and the number of researches increased from just 38 in 2015 to 1962 in 2017. Pakistan has a low share in global publications on Zika with a total number of 24 publications. “Honein Margaret” is considered the most active researcher in the field, by contributing to 80 articles. Most of the published research on Zika virus is from US (47.07%. Conclusion: When compared with other countries, the contribution of Pakistan is negligible with a global share of 0.71% on Zika virus. Serious focus on research is needed in this field realizing the severe medical, ethical, and economic implications of this emerging epidemic in Pakistan.

Henipavirus Mediated Membrane Fusion, Virus Entry and Targeted Therapeutics

Directory of Open Access Journals (Sweden)

Dimitar B. Nikolov

Full Text Available The Paramyxoviridae genus Henipavirus is presently represented by the type species Hendra and Nipah viruses which are both recently emerged zoonotic viral pathogens responsible for repeated outbreaks associated with high morbidity and mortality in Australia, Southeast Asia, India and Bangladesh. These enveloped viruses bind and enter host target cells through the coordinated activities of their attachment (G and class I fusion (F envelope glycoproteins. The henipavirus G glycoprotein interacts with host cellular B class ephrins, triggering conformational alterations in G that lead to the activation of the F glycoprotein, which facilitates the membrane fusion process. Using the recently published structures of HeV-G and NiV-G and other paramyxovirus glycoproteins, we review the features of the henipavirus envelope glycoproteins that appear essential for mediating the viral fusion process, including receptor binding, G-F interaction, F activation, with an emphasis on G and the mutations that disrupt viral infectivity. Finally, recent candidate therapeutics for henipavirus-mediated disease are summarized in light of their ability to inhibit HeV and NiV entry by targeting their G and F glycoproteins.

Polerovirus infection was detected by reverse transcription polymerase chain reaction (RT-PCR) in 29 pepper plants (Capsicum spp.) and one black nightshade plant (Solanum nigrum) sample collected from fields in India, Indonesia, Mali, Philippines, Thailand and Taiwan. At least two representative samples for each country were selected to generate a general polerovirus RT-PCR product of 1.4 kb length for sequencing. Sequence analysis of the partial genome sequences revealed the presence of pepper vein yellows virus (PeVYV) in all 13 samples. A 1990 Australian herbarium sample of pepper described by serological means as infected with capsicum yellows virus (CYV) was identified by sequence analysis of a partial CP sequence as probably infected with a potato leaf roll virus (PLRV) isolate.

A series of suspected cases of Kyasanur Forest disease (KFD) in subjects returning to Belgaum in Karnataka State from Goa, India, is reported herein. KFD was confirmed in 13 out of 76 cases, either by real time RT-PCR or IgM ELISA. No case fatality was recorded. KFD virus positivity was also recorded among humans and monkeys from Sattari taluk in Goa during the same period. The envelope gene sequence of positive human samples from Belgaum showed highest identity of 99.98% to 99.99% with sequences of KFD virus isolated from human cases and monkeys from Goa. KFD activity has been reported from Goa among humans and monkeys since 2015. However, it has not been reported from Belgaum to date. These findings suggest that the cases (migrant laborers) contracted infection during cashew nut harvesting from KFD-affected Keri village, Sattari taluk, Goa and became ill after or during migration from the affected area to their native residence.

History of Nuclear India

Chaturvedi, Ram

2000-04-01

India emerged as a free and democratic country in 1947, and entered into the nuclear age in 1948 by establishing the Atomic Energy Commission (AEC), with Homi Bhabha as the chairman. Later on the Department of Atomic Energy (DAE) was created under the Office of the Prime Minister Jawahar Lal Nehru. Initially the AEC and DAE received international cooperation, and by 1963 India had two research reactors and four nuclear power reactors. In spite of the humiliating defeat in the border war by China in 1962 and China's nuclear testing in 1964, India continued to adhere to the peaceful uses of nuclear energy. On May 18, 1974 India performed a 15 kt Peaceful Nuclear Explosion (PNE). The western powers considered it nuclear weapons proliferation and cut off all financial and technical help, even for the production of nuclear power. However, India used existing infrastructure to build nuclear power reactors and exploded both fission and fusion devices on May 11 and 13, 1998. The international community viewed the later activity as a serious road block for the Non-Proliferation Treaty and the Comprehensive Test Ban Treaty; both deemed essential to stop the spread of nuclear weapons. India considers these treaties favoring nuclear states and is prepared to sign if genuine nuclear disarmament is included as an integral part of these treaties.

Full Text Available INTRODUCTION: Breast cancer is the most common malignancy affecting females worldwide but conventional risk factors are able to explain only a small proportion of these cases. A possible viral etiology for breast cancer has been proposed and Epstein-Barr Virus (EBV is a widely researched candidate virus. The aim of the present study, first one of its kind from India, was to determine if there is a greater association of EBV infection with breast cancer patients as compared to patients with benign breast diseases. METHODS: We looked for expression of Epstein-Barr Virus Nuclear Antigen-1 (EBNA-1 in breast cancer tissue specimens by employing immunohistochemistry (IHC. We also measured levels of anti-EBNA-1 Immunoglobulin (IgG antibodies in stored sera of these patients using commercial Enzyme linked Immunosorbent Assay (ELISA kit. Patients with benign breast diseases were used as a comparison group for both immunohistochemical and serological analysis. RESULTS: 58 cases of malignant breast disease and 63 of benign breast disease (controls were included in the study. Using manufacturer determined cut-off of 3 IU/ml, 50/55 tested (90.9% cases and 27/33 tested (81.8% controls were seropositive for anti-EBNA-1 IgG. Mean antibody levels were significantly higher for cases (54.22 IU/ml as compared to controls (18.68 IU/ml. IHC for EBNA-1 was positive in 28/51 cases (54.9%. No IHC positivity was noted in the tested 30 controls. Our results show that EBNA-1 expression is seen in a significant proportion of breast cancer tissue specimens from rural India and as compared to patients with benign breast diseases these patients also have a higher immunological response against EBNA-1.

Multivariate analysis showed a statistical association only with a duration of sex work of ≤1 year [odds ratio (OR = 3.3; 95% confidence interval (CI 1.4–7.6] and daily income of Rupees (Rp ≥101 (OR = 2.5; 95% CI 1.3–5. Regarding pre-cancerous lesions, 2 of 229 sex workers showed the presence of a low-grade squamous intraepithelial lesion along with high-risk HPV. Thus, 1% of the studied population suffer from a pre-cancerous lesion caused by high-risk HPV. This study concludes that young sex workers are particularly vulnerable to high-risk HPV, similar to human immunodeficiency virus (HIV. The observation of older sex workers relatively free from HPV supports the view of acquired immunity against HPV, which needs to be studied in-depth further. There is a need for a suitable community-based intervention programme targeted towards sex workers, with special reference to younger sex workers, for control and prevention of HPV and cervical cancer. Vaccination against HPV for newly entrant sex workers may be an important component for a successful intervention programme.

2015-09-01

Full Text Available The health care burden of ST elevation myocardial infarction (STEMI in India is enormous. Yet, many patients with STEMI can seldom avail timely and evidence based reperfusion treatments. This gap in care is a result of financial barriers, limited healthcare infrastructure, poor knowledge and accessibility of acute medical services for a majority of the population. Addressing some of these issues, STEMI India, a not-for-profit organization, Cardiological Society of India (CSI and Association Physicians of India (API have developed a protocol of “systems of care” for efficient management of STEMI, with integrated networks of facilities. Leveraging newly-developed ambulance and emergency medical services, incorporating recent state insurance schemes for vulnerable populations to broaden access, and combining innovative, “state-of-the-art” information technology platforms with existing hospital infrastructure, are the crucial aspects of this system. A pilot program was successfully employed in the state of Tamilnadu. The purpose of this article is to describe the framework and methods associated with this programme with an aim to improve delivery of reperfusion therapy for STEMI in India. This programme can serve as model STEMI systems of care for other low-and-middle income countries.

AIDS in India.

Shreedhar, J

1995-01-01

A major HIV epidemic is underway in India, home to 900 million people and the world's second largest population. The director-general of the Indian Council of Medical Research expects India by the year 2000 to be the country with the largest number of HIV infections, with some experts predicting 5 million people to be infected with HIV in India by the year 2000. Others predict 30-55 million to be infected. Although HIV is increasingly spreading to typically low-risk group populations, it is the female sex workers and their clients, long distance truck drivers, men who have sex with men, blood transfusion donors and recipients, and IV drug users throughout the country who are both the reservoirs of HIV and vectors of transmission to the general population. For example, 52% of sex workers in Bombay in 1994 were found to be infected with HIV. Studies indicate that India's long-distance truck drivers average 200 sexual encounters per year; at any given time, 70% of them have STDs. Preliminary surveys estimate that almost 33% are infected with HIV. HIV seroprevalence among truckers in Madras requesting HIV testing because they have STDs increased from almost 60% in 1993 to 91% in 1995. Moreover, the illegal status of homosexuality in India has created an underground culture in which HIV and STDs are rampant; one 1995 study in the Sangli district of Maharashtra found 50% of men who have sex with men to be infected with HIV. Half of India's blood for transfusion is drawn from commercial donors. A Bombay study, however, found 86% of such donors screened in 1992 to be HIV-seropositive and not all blood banks comply with mandatory screening laws. As widespread HIV infection evolves into a multitude of AIDS cases, India's health care system and economy will be heavily taxed, and the number of tuberculosis (TB) cases greatly increased. More than half the population carries the TB bacillus. The government by 1992 had drafted a national prevention and control plan and formed the

This study examines the relationship between entry into the trucking industry during adolescence and both sexually transmitted infections (STIs) and infection by the human immunodeficiency virus (HIV) among long-distance truck drivers in India. Data were sourced from a cross-sectional survey (sample size: 2066) undertaken in 2007 among long-distance truck drivers. The survey spread across major transshipment locations covering the bulk of India's transport volume along four routes. Participants were interviewed about sexual behaviors and were tested for HIV and STIs. The present authors constructed two synthetic cohorts based on the participants' duration of employment in the trucking industry: (1) low (duration ≤ 6 years) and (2) high experience (duration ≥ 7 years). Based on age at entry into the trucking industry, participants were termed as either adolescent (age at entry 4.0%, respectively; adjusted OR: 1.9; 95% CI: 1.2-3.1) and syphilis (5.7% versus 3.5%, respectively; adjusted OR: 1.8; 95% CI: 1.1-3.1). These results suggest the need for focused behavioral change programs in HIV prevention interventions for adolescent truckers in India and elsewhere.

This report illuminates potential areas for collaboration between the EU and India on actions that reduce greenhouse gas emissions in India. If human-induced climate change is to have any hope of being limited to 2 degrees, it is essential that ways are found to address rapidly rising greenhouse gas emissions in India, as elsewhere. This is a challenging proposition: even though India's per capita emissions are very low, her 1.15 billion people are collectively a major source of greenhouse gas emissions. This fact, coupled with the immediate task of tackling widespread poverty, means that the international community must play a major role in providing financial and technological resources to support India's domestic efforts. As India's 2008 National Action Plan on Climate Change recognises, tackling the country's greenhouse gas emissions means not least finding ways to transform a rapidly growing energy sector. International financial mechanisms such as the Clean Development Mechanism and the Global Environment Facility have been unable to deliver the scale of transformative change needed to shift India's emissions trajectory. While the Indian government has already initiated some ambitious policy measures - particularly pertaining to solar energy and energy efficiency- the effectiveness of international finance mechanisms and other forms of international partnership will be crucial in determining the success of greenhouse gas mitigation efforts. The EU India Summit is held a month before COP15 negotiations in Copenhagen. While this provides challenges in terms of seeking concrete agreements on questions of finance, it is also an important opportunity to devise complementary efforts outside the UNFCCC process. Genuine, productive collaboration could not only be used to foster the sorts of transformative changes that are needed in India's growing economy but could also create a spirit of cooperation that spills over into UNFCCC

Goats are the Pakistan's fastest growing ruminants, and Pakistan is the third largest goat producer in the world after India and China. Goat meat preference is the main reason for its increased demand. In the country, there are 25 goat breeds and two wild relatives such as Mark and Goats. At present, Pakistan has 53.8 million goats, according to the 2006 GOP report, and their population growth rate was more than 3% per year (37, 23, 22, and 18% of the goat population in Punjab, Sindh, Balochistan, and NWFP, respectively). Peste des petits ruminants virus (PPRV) belongs to the family Paramyxoviridae and is considered to be one of the major constraints on increasing the productivity of goats and sheep in the areas where they exist and become local. It is closely related to cattle and buffalo rinderpest virus, dogs and other wild predator distemper virus, human measles virus, and marine mammalian measles virus. The present study aimed to determine the screening of the PPRV, Capra Hircus Lin. population, in the Khairpur Mirs District, Sindh, Pakistan. We selected 290 goats for serum sample collection and analysis using competitive ELISA kits according to the manufacturer's instructions. Our results showed that 59 (64%) of the 92 clinical cases were positive and 33 (36%) were seronegative. The study concluded that PPR might be more prevalent in the Khairpur District. Furthermore, it is highly recommended to use homologous PPR-attenuated vaccines to prevent lethal virus attacks that control PPR in the country.

The importance of the evaluation of nuclear structure and decay data has been emphasized in this presentation. Some of the details of the ENSDF evaluation have been discussed. India has been included as one of the centres of NSDD network and several evaluators from India have contributed significantly to the ENSDF evaluation. The interest of the researchers from India in the nuclear structure data evaluation include the mass chain evaluations, decay data evaluation, horizontal evaluation as well as specific measurements related to important nuclear data. There have been several significant contributions in these fields from India. The interest in the ENSDF evaluation and measurements among the nuclear physicists in India is growing. (author)

India established the National Tuberculosis Control Project (NTCP) 50 years ago and re-designed it as Revised NTCP (RNTCP) 19 years ago. Tuberculosis (TB) control was beset with obstacles-BCG vaccination was found ineffective in TB control in 1979; human immunodeficiency virus began spreading in India since 1984 with TB as the commonest opportunistic disease; multi-drug resistance was found to be prevalent since 1992. The World Health Organization declared TB as global emergency in 1993. Yet, RNTCP was extended to the whole nation very slowly, taking 13 years from inception. The first objective of RNTCP, namely 85% treatment success has been achieved and case-fatality had dropped by 90%;. Still, TB burden continues to remain huge; about half the cases are not getting registered under RNTCP; pediatric TB is neglected; TB drains national economy of US$ 23 billion annually. Therefore, TB control is in urgent need of re-design and re-invigoration, with additional inputs and system re-organization to cover all such gaps. We highlight the need for Public Health infrastructure under which all vertical disease control projects such as RNTCP should be synergized for better efficiency and for establishing Public Health Surveillance for collecting denominator-based data on incidence and prevalence to guide course corrections. India ought to spend 3 to 5 times more on TB control than at present. Control needs clear epidemiologic definition and measurable parameters for monitoring the level of control over time. TB control is both a measure of, and a means to, socioeconomic development.

Despite the availability of an inactivated vaccine that has been licensed for >50 years, the influenza virus continues to cause morbidity and mortality worldwide. Constant evolution of circulating influenza virus strains and the emergence of new strains diminishes the effectiveness of annual vaccines that rely on a match with circulating influenza strains. Thus, there is a continued need for new, efficacious vaccines conferring cross-clade protection to avoid the need for biannual reformulation of seasonal influenza vaccines. Recombinant virus-vectored vaccines are an appealing alternative to classical inactivated vaccines because virus vectors enable native expression of influenza antigens, even from virulent influenza viruses, while expressed in the context of the vector that can improve immunogenicity. In addition, a vectored vaccine often enables delivery of the vaccine to sites of inductive immunity such as the respiratory tract enabling protection from influenza virus infection. Moreover, the ability to readily manipulate virus vectors to produce novel influenza vaccines may provide the quickest path toward a universal vaccine protecting against all influenza viruses. This review will discuss experimental virus-vectored vaccines for use in humans, comparing them to licensed vaccines and the hurdles faced for licensure of these next-generation influenza virus vaccines.

U.S.-India safeguards dispute

International Nuclear Information System (INIS)

Sweet, W.

1978-01-01

The current U.S.-India dispute over nuclear safeguards is likely to be the single most important test of the Carter administration's anti-proliferation policies. The Carter administration wants India to accept comprehensive safeguards that would bar further production of nuclear explosives. The Desai government wants to maintain unsafeguarded facilities, in effect keeping the weapons option open. It has been a basic tenet of Indian nuclear policy since the mid-1950s that the big powers must disarm if the small powers are to renounce acquisition of nuclear weapons. As a matter of practical policy, India is willing to forego a nuclear deterrent only if sustained world pressure keeps China's nuclear aspirations in check. As a matter of basic principle, India regards it as unfair and imperialistic that the heavily armed big powers ask for special assurances from the lightly armed small powers. India takes the position that it will cooperate with the United States only voluntarily and only if the nuclear weapon states or at least the superpowers start to clean up their own act. The superpowers must (1) negotiate a comprehensive test ban treaty; (2) accept full-scope safeguards themselves, which would be tantamount to a ban on any further production of weapons-grade materials; and (3) make significant moves toward total nuclear disarmament. The dependence of India on the United States for nuclear supplies is almost negligible. India's major nuclear facilities in operation or under construction include five research reactors, seven power reactors and three reprocessing facilities. Of these 15 facilities, the United States supplied only one (the Tarapur reactor) and 12 of them are not under IAEA safeguards. The United States, in short, is threatening to terminate supplies of low-enriched uranium for just one reactor unless India places these 12 facilities under IAEA safeguards

Full Text Available Abstract Background Prevalence of both cervical cancer and Human Immunodeficiency Virus (HIV infection are very high in India. Natural history of Human Papilloma Virus (HPV infection is known to be altered in HIV positive women and there is an increased possibility of persistence of HPV infections in this population. Therefore, this study was conducted to understand the epidemiology and circulating genotypes of oncogenic HPV among HIV positive and negative female population in West Bengal, India. Methods In this hospital-based cross-sectional study, 93 known HIV positive females attending a pre-ART registration clinic and 1106 HIV negative females attending a Reproductive and Child Health Care Clinic were subjected to study. Cervical cell samples collected from the study population were tested for the presence of HPV 16, 18 using specific primers. Roche PCR assay was used to detect other specific HPV genotypes in the cervical cells specimens of HIV positive cases only. Results Prevalence of HPV 16, 18 among HIV positive females (32.2%; n = 30 was higher than HIV negative females (9.1%; n = 101. About 53% (23/43 of cases with oncogenic HPV were infected with genotypes other than 16, 18 either as single/multiple infections. HPV 18 and HPV 16 were the predominant genotypes among HIV positive and HIV negative subjects respectively. Oncogenic HPV was not found to be associated with age and duration of sexual exposure. But the presence of HIV was found to a statistically significant predictor oncogenic HPV. Conclusion The currently available HPV vaccines offer protection only against HPV 16 and 18 and some cross- protection to few associated genotypes. These vaccines are therefore less likely to offer protection against cervical cancer in HIV positive women a high percentage of who were infected with non-16 and non-18 oncogenic HPV genotypes. Additionally, there is a lack of sufficient evidence of immunogenicity in HIV infected individuals. Therefore

This study aims to investigate the etiological relationship among hepatitis B virus (HBV), hepatitis C virus (HCV), and alcohol as risk factors in a cohort of hepatocellular carcinoma (HCC) patients from India. The clinical and biochemical profiles and tumor characteristics in the HCC cases were also evaluated. A total of 357 consecutive cases of HCC fulfilling the diagnostic criteria from the Barcelona–2000 EASL conference were included in the study. The blood samples were evaluated for serological evidence of HBV and HCV infection, viral load, and genotypes using serological tests, reverse transcription-polymerase chain reaction, and restriction fragment length polymorphism. The male/female ratio for the HCC cases was 5.87:1. Majority of the HCC patients (33.9%) were 50 to 59 years of age, with a mean age of 4±13.23 years. More than half the cases (60.8%) had underlying cirrhosis at presentation. Among the HCC patients, 68.9% were HBV related, 21.3% were HCV related, 18.8% were alcoholic, and 18.2% were of cryptogenic origin. The presence of any marker positive for HBV increased the risk for developing HCC by almost 27 times [OR: 27.33; (12.87–60.0)]. An increased risk of 10.6 times was observed for HCC development for cases positive for any HCV marker [OR: 10.55; (3.13–42.73)]. Heavy alcohol consumption along with HCV RNA positivity in cirrhotic patients was found to be a risk for developing HCC by 3 folds [OR: 3.17; (0.37–70.71)]. Patients of chronic HBV infection followed by chronic HCV infection were at higher risk of developing HCC in India. Chronic alcohol consumption was found to be a risk factor in cirrhotic cases only when it was associated with HCV RNA positivity. Most of the patients had a large tumor size (>5 cm) with multiple liver nodules, indicating an advanced stage of the disease thus making curative therapies difficult

Full Text Available Objective – Waqf is a unique feature of the socioeconomic system of Islam in a multi- religious and developing country like India. India is a rich country with waqf assets. The history of waqf in India can be traced back to 800 years ago. Most of the researchers, suggest how waqf can be used a tool to mitigate the poverty of Muslims. India has the third highest Muslim population after Indonesia and Pakistan. However, the majority of Muslims belong to the low income group and they are in need of help. It is believed that waqf can be utilized for the betterment of Indian Muslim community. Among the available uses of waqf assets, the main objective of this paper is to introduce waqf based takaful model in India. In addition, how this proposed model can be adopted in India is highlighted.Methods – Library research is applied since this paper relies on secondary data by thoroughlyreviewing the most relevant literature.Result – India as a rich country with waqf assets should fully utilize the resources to help the Muslims through takaful.Conclusion – In this study, we have proposed waqf based takaful model with the combination of the concepts mudarabah and wakalah for India. We recommend this model based on the background of the  country and situations. Since we have not tested the viability of this model in India, future research should be continued on this testing.Keywords : Wakaf, Takaful, Kemiskinan dan India

Newcastle Disease Viruses Causing Recent Outbreaks Worldwide Show Unexpectedly High Genetic Similarity to Historical Virulent Isolates from the 1940s

Virulent strains of Newcastle disease virus (NDV) cause Newcastle disease (ND), a devastating disease of poultry and wild birds. Phylogenetic analyses clearly distinguish historical isolates (obtained prior to 1960) from currently circulating viruses of class II genotypes V, VI, VII, and XII through XVIII. Here, partial and complete genomic sequences of recent virulent isolates of genotypes II and IX from China, Egypt, and India were found to be nearly identical to those of historical viruses isolated in the 1940s. Phylogenetic analysis, nucleotide distances, and rates of change demonstrate that these recent isolates have not evolved significantly from the most closely related ancestors from the 1940s. The low rates of change for these virulent viruses (7.05 × 10−5 and 2.05 × 10−5 per year, respectively) and the minimal genetic distances existing between these and historical viruses (0.3 to 1.2%) of the same genotypes indicate an unnatural origin. As with any other RNA virus, Newcastle disease virus is expected to evolve naturally; thus, these findings suggest that some recent field isolates should be excluded from evolutionary studies. Furthermore, phylogenetic analyses show that these recent virulent isolates are more closely related to virulent strains isolated during the 1940s, which have been and continue to be used in laboratory and experimental challenge studies. Since the preservation of viable viruses in the environment for over 6 decades is highly unlikely, it is possible that the source of some of the recent virulent viruses isolated from poultry and wild birds might be laboratory viruses.

Severe acute respiratory infection (SARI) is one of the leading causes of death among children worldwide. As different respiratory viruses exhibit similar symptoms, simultaneous detection of these viruses in a single reaction mixture can save time and cost. The present study was done in a tertiary care children's hospital for rapid identification of viruses causing SARI among children less than or equal to five years of age using multiplex real-time reverse transcription polymerase chain reaction (RT-PCR) kit. A total of 155 throat swabs were collected from equal number of children suspected to have SARI and processed for extraction of nucleic acids using automated extraction system. Multiplex real-time RT-PCR was done to identify the viruses in the samples. The overall positivity for viruses in the study was found to be 72.9 per cent with a co-infection rate of 19.5 per cent. Human metapneumovirus (HMPV) was the predominant virus detected in 25.7 per cent children followed by influenza A (H1N1)pdm09, human rhinovirus (HRV) and human adenovirus (HAdV) in 19.9, 11.0 and 8.8 per cent children, respectively. The HMPV was at its peak in February 2013, HAdV showed two peaks in March-April, 2012 and November 2012-March 2013 while HRV was detected throughout the year. Multiplex real-time PCR helped in rapid identification of viruses. Seventeen viruses were detected in SARI cases with overall positivity of 72.9 per cent. HMPV was the most predominant virus. However, for better clinico-virological correlation, studies are required with complete work up of all the aetiological agents, clinical profile of patients and treatment outcome.

Humanizing HIV/AIDS and its (re)stigmatizing effects: HIV public 'positive' speaking in India.

Finn, Mark; Sarangi, Srikant

2009-01-01

Social stigma has been inextricably linked with HIV and AIDS since the epidemic erupted in the early 1980s. The stigma that has built up around HIV and AIDS is generally regarded as having a negative impact on the quality of life of HIV-positive people and on general prevention efforts. Current attempts to combat HIV-related stigma focus on increasing the acceptance of HIV among the stigmatizing public and stigmatized individuals alike. In this, the global HIV-positive community is being increasingly called upon to ;humanize' the virus, not least through public displays of HIV 'positive' health and public ;positive' speaking. This article critically explores the constitutive effects and inherent power relations of HIV Positive Speakers' Bureaus (PSBs) as a platform for such a display. Adopting a post-structuralist discourse analytic approach, we explore accounts of positive-speaking and HIV health from HIV-related non-government organizations in India and in PSB training manuals. In particular, we highlight ways in which positive-speaking in India can be seen to have significant (re)stigmatizing effects by way of ambivalent and hyper-real configurations of HIV 'positive' identity and life.

2010-03-01

Full Text Available Abstract Background Co-infections of hepatitis B and C viruses are frequent with HIV due to shared routes of transmission. In most of the tertiary care health settings, HIV reactive patients are routinely tested for HBsAg and anti-HCV antibodies to rule out these co-infections. However, using the routine serological markers one can only detect active HBV infection while the occult HBV infection may be missed. There is insufficient data from India on HIV-HBV co-infection and even scarce on occult HBV infection in this group. Methods We estimated the burden of HBV infection in patients who were tested positive for HIV at a tertiary care centre in north India. We also attempted to determine the prevalence and clinical characteristics of occult HBV infection among these treatment-naïve patients and compare their demographic features with other HIV patients. During a period of 6 years between January 2002 to December 2007, 837 HIV positive patients (631 males and 206 females (M: F :: 3.06:1 were tested for serological markers of HBV (HBsAg and HCV (anti-HCV antibodies infections in our laboratory. For comparison 1000 apparently healthy, HIV-negative organ donors were also included in the study. Data on demographics, sexual behaviour, medical history, laboratory tests including the serum ALT and CD4 count of these patients were recorded. A sub-group of 53 HBsAg negative samples from HIV positive patients were assessed for anti-HBs, anti-HBc total (IgG+IgM and HBV-DNA using a highly sensitive qualitative PCR and analysed retrospectively. Results Overall, 7.28% of HIV positive patients showed presence of HBsAg as compared to 1.4% in the HIV negative control group. The prevalence of HBsAg was higher (8.55% in males than females (3.39%. The study revealed that occult HBV infection with detectable HBV-DNA was prevalent in 24.5% of patients positive for anti-HBc antibodies; being 45.5% in HBsAg negative patients. Most importantly the occult infection was

Nairobi sheep disease virus (NSDV) of the genus Nairovirus causes a haemorrhagic gastroenteritis in sheep and goats with mortality up to 90%; the virus is found in East and Central Africa, and in India, where the virus is called Ganjam virus. NSDV is closely related to the human pathogen Crimean-Congo haemorrhagic fever virus, which also causes a haemorrhagic disease. As with other nairoviruses, replication of NSDV takes place in the cytoplasm and the new virus particles bud into the Golgi apparatus; however, the effect of viral replication on cellular compartments has not been studied extensively. We have found that the overall structure of the endoplasmic reticulum (ER), the ER-Golgi intermediate compartment and the Golgi were unaffected by infection with NSDV. However, we observed that NSDV infection led to the loss of protein disulphide isomerase (PDI), an oxidoreductase present in the lumen of the endoplasmic reticulum (ER) and which assists during protein folding, from the ER. Further investigation showed that NSDV-infected cells have high levels of PDI at their surface, and PDI is also secreted into the culture medium of infected cells. Another chaperone from the PDI family, ERp57, was found to be similarly affected. Analysis of infected cells and expression of individual viral glycoproteins indicated that the NSDV PreGn glycoprotein is involved in redistribution of these soluble ER oxidoreductases. It has been suggested that extracellular PDI can activate integrins and tissue factor, which are involved respectively in pro-inflammatory responses and disseminated intravascular coagulation, both of which manifest in many viral haemorrhagic fevers. The discovery of enhanced PDI secretion from NSDV-infected cells may be an important finding for understanding the mechanisms underlying the pathogenicity of haemorrhagic nairoviruses.

Mistry, Nerges; Tolani, Monica; Osrin, David

2012-01-01

Operations research (OR) is well established in India and is also a prominent feature of the global and local agendas for tuberculosis (TB) control. India accounts for a quarter of the global burden of TB and of new cases. Multidrug-resistant TB is a significant problem in Mumbai, India’s most populous city, and there have been recent reports of totally resistant TB. Much thought has been given to the role of OR in addressing programmatic challenges, by both international partnerships and India’s Revised National TB Control Programme. We attempt to summarize the major challenges to TB control in Mumbai, with an emphasis on drug resistance. Specific challenges include diagnosis of TB and defining cure, detecting drug resistant TB, multiple sources of health care in the private, public and informal sectors, co-infection with human immunodeficiency virus (HIV) and a concurrent epidemic of non-communicable diseases, suboptimal prescribing practices, and infection control. We propose a local agenda for OR: modeling the effects of newer technologies, active case detection, and changes in timing of activities, and mapping hotspots and contact networks; modeling the effects of drug control, changing the balance of ambulatory and inpatient care, and adverse drug reactions; modeling the effects of integration of TB and HIV diagnosis and management, and preventive drug therapy; and modeling the effects of initiatives to improve infection control.

2007-07-01

The concept of outsourcing for the development and global studies on new drugs has become widely accepted in the pharmaceutical industry due to its cost and uncertainty. India is going to be the most preferred location for contract pharma research and development due to its huge treatment naïve population, human resources, technical skills, adoption/amendment/implementation of rules/laws by regulatory authorities, and changing economic environment. But still 'miles to go' to fulfill the pre-requisites to ensure India's success. In spite of all the pitfalls, the country is ambitious and optimist to attract multinational pharmaceutical companies to conduct their clinical trials in India.

Challenges in India and Bhutan.

While India is making overall progress in maternal and child health and reproductive health (MCH/RH), all states are not moving ahead. In fact, it is the states with the larger populations which are lagging behind. Primary education, women's status, and literacy remain problematic. UNFPA has worked in India for a long time, helping to realize the decline in total fertility rate from 6 to 3.5 over the past 20-30 years. India's population, however, is still growing at the annual rate of 1.8%. UNFPA's program in India for the period 1997-2001 will stress women's health as a matter of overall reproductive health, a new approach in India which has long relied upon sterilization. Attention must be given to meeting the needs of the poor in India as the country continues to grow in size and wealth. While Bhutan's estimated population is just over 1 million, the annual population growth rate of 3.1% threatens development over the long term. With a mountainous terrain and a low resource base, Bhutan cannot sustain a high population growth rate. Significant improvements have been made and women's status is good, the infant mortality rate has been reduced, and the health infrastructure is not bad. UNFPA's 5-year program beginning in 1998 will mainly address RH, especially adolescent RH.

Full Text Available The present study broadly attempts to analyze the role of Fiscal Responsibility and Budget Management Act in restoring fiscal balance in India. It analyses the need for fiscal rules and constraints in India. The study aims at finding out the major factor behind rising fiscal imbalance in India and to examine whether there is an electoral motive towards high fiscal deficit to GDP ratio or not. It also analyzes the effectiveness of various measures undertaken at the central and state level to inculcate fiscal discipline in the fiscal management. The study also makes an attempt to do a critical in depth reviews of the Fiscal Responsibility and Budget Management Act and make an attempt at examining effectiveness and suitability of FRBM Act through a quantitative analysis. It also makes an attempt to suggest improvements in the fiscal monitoring mechanism in India. We employ Ordinary Least Square (OLS method to examine the impact of Fiscal Responsibility and Budget Management Act on fiscal deficit in India using the data for the period 1980-81 to 2008-09. The regression results indicates that FRBM Act does not have a significant effect on the Gross Fiscal Deficit (GFD to GDP ratio where as GDP (at factor cost growth rate has a significant negative effect on the GFD to GDP ratio.

India's economic rise since the 1990s has been followed by a more prominent global role for the country. Despite economic setbacks in recent years and huge domestic challenges like poverty, caste issues, and gender inequality, India today is almost universally characterised as an “emerging power”. At the same time, the country continues to show an enormous diversity. Thus, exploring emerging India can surely not be confined to economic analysis only.

Determinants of Foreign Institutional Investors’ Investment in India

Directory of Open Access Journals (Sweden)

Manjinder KAUR

2010-11-01

Full Text Available The present study aims at exploring the determinants of Foreign Institutional Investors’ (FIIs investment in India. Returns on Indian stock market have positive impact whereas US stock market returns have no significant influence on FIIs investment to India. Stock market risk has negative influence on FIIs inflows to India. Market capitalization and stock market turnover of India have significant positive influence only in short-run. Among macroeconomic determinants, economic growth of India has positive impact on FIIs investment both in long-run and shortrun. But all other macroeconomic factors have significant influence only in long-run like inflation in US has positive influence whereas inflation in India has negative influence on FIIs investment. Further, US interest rate has adverse impact on FIIs investment while liberalization policies of India exhibited significant contribution to FIIs inflows. Study concludes that FIIs inflows in India are determined by both stock market characteristics and macroeconomic factors.

Clinical specimens from all the outbreaks were screened by polymerase chain reaction followed by restriction fragment length polymorphism (PCR-RFLP) and confirmed the diseases as Goat Pox. Virus isolation in Vero cell line was done with randomly selected ten samples, cytopathic effects (CPE) characterized by syncytia and intracytoplasmic inclusion bodies were observed after several blind passages. Nucleotide sequence of complete p32 gene using randomly selected two isolates and three clinical specimens revealed presence of Goat pox virus (GTPV)-specific signature residues in all the sequences. Phylogenetic analysis using the present five sequences along with GenBank data of GTPV complete p32 gene sequences showed all the GTPV sequences cluster together except Pellor strain (NC004003) and FZ Chinese strain (KC951854). The five sequences either from WB or TN cluster more closely with GTPV isolates of Maharashtra state that were responsible for cross species outbreak of pox disease in both sheep (KF468759) and goats (KF468762) in India during the year 2010. All the Indian goat pox viruses, including the Mukteswar strain, isolated in 1946 and sequence reported in 2004 clustered together with the GTPVs causing the recent outbreaks. It was observed that GTPVs caused similar clinical manifestation irrespective of their geographical locations and breed characteristics, no variation observed among the Indian isolates based on p32 gene over the period of seventy years and disease outbreaks could not be observed or reported in vaccinated goats. © 2017 Blackwell Verlag GmbH.

Abstract Microbial diseases are a serious hindrance to successful shrimp aquaculture. The Pacific white shrimp Litopenaeus vannamei is an exotic species recently introduced in India to supplement the failing aquaculture of the Asian tiger shrimp Penaeus monodon due to viral diseases. However, after a brief initial success, the aquaculture of L. vannamei is also experiencing serious problems due to microbial diseases. In this study, we conducted a microbiological investigation into the problem of persistent mortalities in selected L. vannamei farms on the southeastern coast of India. The infected shrimps were positive for the white spot syndrome virus (WSSV) by a nested PCR, though no visible white spots were present on the animals. The shrimps were heavily colonized by Vibrio parahemolyticus, which were isolated from the hepatopancreas, gills, and the body surface. The pond water, despite being low saline groundwater, harbored large numbers of V. parahemolyticus and other Vibrio species, and V. parahemolyticus isolated from L. vannamei were resistant to β-lactam antibiotics and cephalosporins. Our results strongly suggest that the persistent mortalities of L. vannamei were due to a co-infection by V. parahemolyticus and WSSV. Received December 16, 2013; accepted February 14, 2014.

Comparison of the pathogenicity of Nipah virus isolates from Bangladesh and Malaysia in the Syrian hamster.

Directory of Open Access Journals (Sweden)

Blair L DeBuysscher

Full Text Available Nipah virus is a zoonotic pathogen that causes severe disease in humans. The mechanisms of pathogenesis are not well described. The first Nipah virus outbreak occurred in Malaysia, where human disease had a strong neurological component. Subsequent outbreaks have occurred in Bangladesh and India and transmission and disease processes in these outbreaks appear to be different from those of the Malaysian outbreak. Until this point, virtually all Nipah virus studies in vitro and in vivo, including vaccine and pathogenesis studies, have utilized a virus isolate from the original Malaysian outbreak (NiV-M. To investigate potential differences between NiV-M and a Nipah virus isolate from Bangladesh (NiV-B, we compared NiV-M and NiV-B infection in vitro and in vivo. In hamster kidney cells, NiV-M-infection resulted in extensive syncytia formation and cytopathic effects, whereas NiV-B-infection resulted in little to no morphological changes. In vivo, NiV-M-infected Syrian hamsters had accelerated virus replication, pathology and death when compared to NiV-B-infected animals. NiV-M infection also resulted in the activation of host immune response genes at an earlier time point. Pathogenicity was not only a result of direct effects of virus replication, but likely also had an immunopathogenic component. The differences observed between NiV-M and NiV-B pathogeneis in hamsters may relate to differences observed in human cases. Characterization of the hamster model for NiV-B infection allows for further research of the strain of Nipah virus responsible for the more recent outbreaks in humans. This model can be used to study NiV-B pathogenesis, transmission, and countermeasures that could be used to control outbreaks.

Full Text Available Abstract Background Occult hepatitis B virus (HBV infection might transmit viremic units into the public blood supply if only hepatitis B surface antigen (HBsAg testing is used for donor screening. Our aim was to evaluate the prevalence of occult HBV infection among the HBsAg negative/antiHBc positive donations from a highly HIV prevalent region of India. Methods A total of 729 HBsAg negative donor units were included in this study. Surface gene and precore region were amplified by in house nucleic acid test (NAT for detection of occult HBV infection and surface gene was analyzed after direct sequencing. Results A total of 220 (30.1% HBsAg negative donors were antiHBc positive, of them 66 (30% were HBV DNA positive by NAT. HBV DNA positivity among 164 antiHBc only group, was 27.1% and among 40 antiHBs positive group was 30.0%. HBV/D (93.3% was predominant and prevalence of both HBV/C and HBV/A was 3.3%. Single or multiple amino acids substitutions were found in 95% samples. Conclusion Thus, a considerable number of HBV infected donors remain undiagnosed, if only HBsAg is used for screening. Addition of antiHBc testing for donor screening, although will lead to rejection of a large number of donor units, will definitely eliminate HBV infected donations and help in reducing HBV transmission with its potential consequences, especially among the immunocompromised population. The HBV genetic diversity found in this donor population are in accordance with other parts of India.

This demographic profile of India addresses fertility, family planning, and economic issues. India is described as a country shifting from economic policies of self-reliance to active involvement in international trade. Wealth has increased, particularly at higher educational levels, yet 25% still live below the official poverty line and almost 66% of Indian women are illiterate. The government program in family planning, which was instituted during the early 1950s, did not change the rate of natural increase, which remained stable at 2.2% over the past 30 years. 1993 marked the first time the growth rate decline to under 2%. The growth rate in 1995 was 1.9%. The total population is expected double in 36 years. Only Nigeria, Pakistan, and Bangladesh had a higher growth rate and higher fertility in 1995. India is geographically diverse (with the northern Himalayan mountain zone, the central alluvial plains, the western desert region, and the southern peninsula with forest, mountains, and plains). There are regional differences in the fertility rates, which range from replacement level in Kerala and Goa to 5.5 children in Uttar Pradesh. Fertility is expected to decline throughout India due to the slower pace of childbearing among women over the age of 35 years, the increase in contraceptive use, and increases in marriage age. Increased educational levels in India and its state variations are related to lower fertility. Literacy campaigns are considered to be effective means of increasing the educational levels of women. Urbanization is not expected to markedly affect fertility levels. Urban population, which is concentrated in a few large cities, remains a small proportion of total population. Greater shifts are evident in the transition from agriculture to other wage labor. Fertility is expected to decline as women's share of labor force activity increases. The major determinant of fertility decline in India is use of family planning, which has improved in access

Energy use in rural India

Energy Technology Data Exchange (ETDEWEB)

Revelle, R

1976-06-01

The methods are described by which human and animal energies have been calculated for India. From an energy standpoint, rural India can be thought of as a partially closed ecosystem in which energy derived by people and animals from the photosynthetic products of plants is used to grow and prepare food for humans which in turn provides an essential energy input to grow more food, resulting in an endless cycle. The ecosystem is being disrupted by rapid population growth in India. The extent of the use of non-commercial fuels in villages and towns was determined by the Energy Survey of India Committee in the early 1960's. The committee reported utilization of about 120 million metric tons of wood, 50 million tons of dried dung, and 30 million tons of vegetable waste each year in villages and in urban areas. In terms of U.N. coal equivalents, the energy derived from burning wood, dung, and crop residues adds up to 227 kg per capita per year, or a total for rural India of 100 million tons, with an energy content of 7.53 x 10/sup 14/ kcal. It is projected that 90 percent of this is utilized for cooking and space heating and 10 percent for pottery and brickmaking, metalworking and blacksmithing, and sugar making. In terms of U.N. coal equivalents, the commercial energy use per capita in rural India in 1971 was 37 kg, and the total use in rural population was 16.3 million tons. It is projected here that 12 percent was used for cooking and space heating, 40 percent for lighting, and 48 percent for agriculture. A comparison of U.S. and Indian energy consumption is made. The conclusion that more energy will be needed to support the populace in India is discussed. (MCW)

A highly contagious virus infection in horses, influenza is the single most important equine respiratory disease in the world. This paper presents details of a one-year study (1 June 2008 to 31 May 2009) to determine the prevalence of equine influenza in the horses of Gujarat State in India. The prevalence of equine influenza A/equi-2 was 12.02%, but none of the samples were positive for equine influenza A/equi-1. The prevalence of equine influenza (A/equi-2) was 15.38%, 11.94%, 10.18%, and 9.09% in horses of the Kathiyawari breed, a non-descript breed, the Marwari breed and the Indian Thoroughbred breed, respectively. The highest prevalence of influenza was observed in yearlings (17.48%) and prevalence was at its highest in the month of April (28.89%). The prevalence rate in males, females and geldings was 11.95%, 10.38% and 8.47%, respectively. The mortality rate and case fatality rate were 1.28% and 10.64%, respectively.

Women's cardiovascular health in India.

Cardiovascular diseases (CVDs) are the leading cause of death among adult women in many parts of India and a major cause of morbidity. In some parts of the world, gender inequities have been observed in cardiovascular healthcare and cardiovascular outcomes. The authors discuss the data for potential disparities in cardiovascular healthcare for women in India. Data on cardiovascular healthcare provision and CVD outcomes among women in India are generally lacking. The little available data suggest that women in rural areas, younger women and girl children with CVD are less likely to receive appropriate management than men, with this disparity most apparent in those of lower socioeconomic status and education. However, there is a particular lack of information about the prevention and management of atherosclerotic heart disease in women from a range of communities that comprise the extremely diverse population of India.

India's baseline plan for nuclear energy self-sufficiency

International Nuclear Information System (INIS)

Bucher, R.G.

2009-01-01

India's nuclear energy strategy has traditionally strived for energy self-sufficiency, driven largely by necessity following trade restrictions imposed by the Nuclear Suppliers Group (NSG) following India's 'peaceful nuclear explosion' of 1974. On September 6, 2008, the NSG agreed to create an exception opening nuclear trade with India, which may create opportunities for India to modify its baseline strategy. The purpose of this document is to describe India's 'baseline plan,' which was developed under constrained trade conditions, as a basis for understanding changes in India's path as a result of the opening of nuclear commerce. Note that this treatise is based upon publicly available information. No attempt is made to judge whether India can meet specified goals either in scope or schedule. In fact, the reader is warned a priori that India's delivery of stated goals has often fallen short or taken a significantly longer period to accomplish. It has been evident since the early days of nuclear power that India's natural resources would determine the direction of its civil nuclear power program. It's modest uranium but vast thorium reserves dictated that the country's primary objective would be thorium utilization. Estimates of India's natural deposits vary appreciably, but its uranium reserves are known to be extremely limited, totaling approximately 80,000 tons, on the order of 1% of the world's deposits; and nominally one-third of this ore is of very low uranium concentration. However, India's roughly 300,000 tons of thorium reserves account for approximately 30% of the world's total. Confronted with this reality, the future of India's nuclear power industry is strongly dependent on the development of a thorium-based nuclear fuel cycle as the only way to insure a stable, sustainable, and autonomous program. The path to India's nuclear energy self-sufficiency was first outlined in a seminal paper by Drs. H. J. Bhabha and N. B. Prasad presented at the Second

Full Text Available Japanese encephalitis (JE is endemic in many parts of India including the state of West Bengal. In West Bengal, the first major outbreaks of JE occurred in the districts of Bankura and Burdwan in 1973. The Culex vishnui subgroup of mosquitoes has been implicated as major vectors of JE. However in India, JE virus (JEV has been isolated from 16 species of mosquitoes. During September 2011, JE cases were reported from four districts -Jalpaiguri, Darjeeling, Dinajpur and Cooch Behar of West Bengal (North. Adult mosquitoes were collected, identified, pooled and screened for JEV using antigen capture ELISA. Out of 279 mosquito pools tested, one pool of Cx. pseudovishnui and three pools of Cx. quinquefasciatus were found positive for JEV. The ELISA positive pools were further confirmed as JEV by insect bioassay (Toxo-IFA. Two pools of Cx. quinquefasciatus were confirmed as JEV. This represents the first report of JEV isolation from Cx. quinquefasciatus in West Bengal.

In the decades following India's independence from British rule in 1947, the West's image of India was summarized in three simple cliches: the world's largest democracy, an impoverished continent, and economic growth hampered by a fussy bureaucracy and the caste system, all in a context of a particular religion. These cliches are perhaps one of the reasons that the success of India's green revolution was recognized so late, a revolution that allowed the country to develop its agricultural sector and to feed its population. Since the 1990's, the easing of planning constraints have liberated the Indian economy and allowed it to embark on a more significant path of growth. New cliches have begun to replace the old: India will become a second China and, lagging by 10 to 20 years, will follow the same trajectory, with its development marked more by services and the use of renewable energy. However, these trends will not prevent primary energy demand from exploding. On the contrary, India faces difficult choices on how it increases clean, secure, affordable energy to all its citizens. Many of the choices are the same as found elsewhere, but on a scale matched only by China. The IFRI European Governance and Geopolitics of Energy Project intends this study to deepen public understanding of the magnitude of India's challenges. Various aspects of the serious energy problems are studied throughout this monograph. The authors have written freely on these matters without attempting to reconcile their different viewpoints. The first chapter, by Maite Jaureguy-Naudin and Jacques Lesourne, presents an overview of India's present and future energy system. The authors follow a prudent but realistic view of India's future. The second chapter, by Jean-Joseph Boillot, a French expert on India who has published several books and articles on this subject, and Nicolas Autheman, research fellow, describes in greater detail the specifics of India

Only a small portion (15%) of India's commerical energy requirements is imported, but this import accounts for nearly 75% of total imports. Noncommercial energy (firewood, agricultural waste, cow dung) will still have an important role in the future. The major thrust of India's energy policy should be to ensure that energy will not be a constraint to economic growth, and to increase the per capita energy consumption. In the future, hydroelectric and nuclear power will become increasingly important. Solar energy will also be utilized. (DLC)

Analysis of Human Papilloma Virus 16/18 DNA and its Correlation with p16 Expression in Oral Cavity Squamous Cell Carcinoma in North-Eastern India: A Chromogenic in-situ Hybridization Based Study

Background The incidence of head and neck squamous cell carcinoma (HNSCC) is quite high in North Eastern India. Apart from the traditional risk factors like tobacco and alcohol consumption, human papilloma virus (HPV) is now considered an established causative agent. These HPV related tumour have a clinico-pathological profile that is quite divergent from conventional non-HPV related tumours. Association of HPV in oral cancers has not been explored in north-east India. Materials and Methods Thirty-one patients with oral cavity squamous cell carcinoma (OSCC) on treatment from October 2010 to January 2013 were included in the study. Patients who received neo-adjuvant chemotherapy were excluded. HPV 16/18 DNA was evaluated using Chromogenic in-situ Hybridization (CISH). Presence of nuclear signals was taken as positive HPV expression. p16 was evaluated using immunohistochemistry and was considered positive if ≥ 80% of the tumour cells showed strong and diffuse nuclear/cytoplasmic immunostaining. The results were analysed using Fisher exact test and confidence interval was calculated where required. Results The study group age ranged from 30 to 80 years (median age- 54.2 years). The most common site was gum, with well differentiated squamous cell carcinoma being the most common histology. HPV 16/18 DNA was positive in 29% (95% CI: 13.03% - 44.97%) cases and had a clear tendency towards statistical significance with non-smoker cases (p=0.05), lymph node metastasis (p=0.05) and a significant correlation with p16 overexpression (p=0.04). There was no significant correlation with other clinico-pathological parameters. Conclusion HPV 16/18 is associated with OSCC, commonly seen among non-smokers and may be related to nodal metastasis. So, HPV may be used as a prognostic factor in OSCC and p16 may be considered as a surrogate marker for HPV. PMID:26435951

Healthcare biotechnology in India.

Srivastava, L M

2005-01-01

Biotechnology in India has made great progress in the development of infrastructure, manpower, research and development and manufacturing of biological reagents, biodiagnostics, biotherapeutics, therapeutic and, prophylactic vaccines and biodevices. Many of these indigenous biological reagents, biodiagnostics, therapeutic and prophylactic vaccines and biodevices have been commercialized. Commercially when biotechnology revenue has reached $25 billions in the U.S. alone in 2000 excluding the revenues of biotech companies that were acquired by pharmaceutical companies, India has yet to register a measurable success. The conservative nature and craze of the Indian Industry for marketing imported biotechnology products, lack of Government support, almost non-existing national healthcare system and lack of trained managers for marketing biological and new products seem to be the important factors responsible for poor economic development of biotechnology in India. With the liberalization of Indian economy, more and more imported biotechnology products will enter into the Indian market. The conditions of internal development of biotechnology are not likely to improve in the near future and it is destined to grow only very slowly. Even today biotechnology in India may be called to be in its infancy.

India has got the best possible agreement

Sreenivasan, T.P.

2008-01-01

The Indians wanted an agreement that will be acceptable to their people and the IAEA wanted to make sure that Uncle Sam was on board. The positions of both are reflected in the balanced document that has been emerged from negotiations. The terms of the proposed inspections have been set without compromising India's sovereign right to manage its nuclear facilities in its best interests in the spirit of the India-US Joint Statement of 2005. The non-proliferationists complain that India got away with too much and the liberationists complain that India gave away too much in the negotiations on the safeguards agreement. The fact that India has nuclear weapons make the inspections less stringent. The expectations is that as India switches to indigenous fuel, the inspections will cease altogether. Much has been said about the reference to the 'corrective measures' that India may take in the event of disruption of supplies. The non- proliferationists and the liberationists find this provision too vague. One windfall that has come in India's way, whether by design or as logical consequence of the new approach, is that the other safeguards agreements, which are applicable to facilities that use imported fuel, will be suspended as long as the new safeguards agreement is in force. The goodwill of the IAEA and its Director General, Mohammed ElBaradei, has played a major role in the accomplish of this agreement.

Hepatitis B virus surface antigen and anti-hepatitis C virus rapid tests underestimate hepatitis prevalence among HIV-infected patients.

In the case of coinfection with HIV and hepatitis B virus (HBV) and/or hepatitis C virus (HCV), hepatic disease progression is often accelerated, with higher rates of liver cirrhosis and liver-related mortality. We aimed to evaluate the performance of the rapid tests used routinely to detect HBV surface antigen (HBsAg) and anti-HCV among HIV-infected patients in Guinea-Bissau. Blood samples from HIV-infected patients in Guinea-Bissau were stored after testing for HBsAg and anti-HCV with rapid tests. Samples were subsequently re-tested for HBsAg and anti-HCV in Denmark. Two rapid tests were used in Guinea-Bissau: HBsAg Strip Ref 2034 (VEDA.LAB, Alençon, France; sensitivity 62.3%; specificity 99.2%) and HEPA-SCAN (Bhat Bio-Tech, Bangalore, India; sensitivity 57.1%; specificity 99.7%). In the two tests the ability to obtain the correct outcome depended on the antigen and antibody concentrations, respectively. Sex, age, CD4 cell count and antiretroviral therapy status did not differ between false negative and true positive samples in either of the tests. The study is limited by a low number of anti-HCV positive samples. New diagnostic rapid tests should always be evaluated in the setting in which they will be used before implementation. © 2014 British HIV Association.

This is important globally because countries with the lowest nursing and healthcare workforce capacities have the poorest health outcomes. This review sought to synthesize and unify the evidence about nurse migration from India and includes a look at nurse retention within India. A comprehensive literature review was performed to synthesize and unify both qualitative and quantitative research. Bibliographic databases searched included CINAHL, MEDLINE, PsycINFO, and EconLit using associated keywords for empirical and descriptive literature published between January 2004 and May 2014. Hand searches of the Nursing Journal of India from 2004 to February 2014 and the Journal of Nursing Research Society of India from its inception in 2007-February 2014 were also completed. 29 studies were selected and analyzed for the review. Data were appraised for quality; reduced through sub-categorization; extracted; and coded into a framework. Thematic interpretation occurred through comparing and contrasting performed by multiple reviewers. Findings included an exponential growth in nurse recruitment efforts, nurse migration, and a concomitant growth in educational institutions within India with regional variations in nurse migration patterns. Decision-making factors for migration were based on working conditions, salience of family, and the desire for knowledge, skill, technology, adventure and personal enrichment. Challenges associated with migration included questionable recruiting practices, differing scopes of practice encountered after migration and experiences of racism and cultural differences. A shift toward a positive transformation of nursing status in India has resulted in an increased respect for individual nurses and the profession of nursing. This was attributed to the increased globalization of nursing. Results from this

Epidemiology of hepatocellular carcinoma in India.

Indian data on epidemiology of HCC is not available. Cancer is not a reportable disease in India and the cancer registries in India are mostly urban. National cancer registry program of the Indian Council of Medical Research (ICMR) has been recently expanded to include 21 population based and 6 hospital based cancer registries. The last published registry data by ICMR available in the cancer registry website (www.ncrpindia.org) was in 2008 which provides information on various cancers from 2006 to 2008. The other source of information was the report published by International Agency for Research on Cancer (WHO). According to these available data the age adjusted incidence rate of hepatocellular carcinoma (HCC) in India for men ranges from 0.7 to 7.5 and for women 0.2 to 2.2 per 100,000 population per year. The male:female ratio for HCC in India is 4:1. The age of presentation varies from 40 to 70 years. According to a study conducted by verbal autopsy in 1.1 million homes representing the whole country, the age standardized mortality rate for HCC in India for men is 6.8/100,000 and for women is 5.1/100,000. According to another study the incidence of HCC in cirrhotics in India is 1.6% per year. The unpublished data from various tertiary care centers suggest that the incidence of HCC is increasing in India. There is a need for a multi-centric HCC registry under the aegis of INASL.

Chikungunya virus (CHIKV) is a major threat to Australia given the distribution of competent vectors, and the large number of travellers returning from endemic regions. We describe current knowledge of CHIKV importations into Australia, and quantify reported viraemic cases, with the aim of facilitating the formulation of public health policy and ensuring maintenance of blood safety. Cases reported to the National Notifiable Disease Surveillance System (NNDSS) from 2002 to 2012 were analysed by place, month of acquisition, and place of residence. Rates of chikungunya importation were estimated based on reported cases and on the numbers of short-term movements. Between 2002 and 2012, there were 168 cases of chikungunya virus (CHIKV) imported into Australia. Victoria and New South Wales had the largest number of notifications. The main sources were Indonesia, India and Malaysia. The number of cases increased from 2008 to reach a peak in 2010 (n=64; 40%). Although Indonesia accounted for the majority of CHIKV notifications in Australia, travel from India had the highest CHIKV importation rate (number of imported cases per 100,000 travellers). The Australian population is increasingly at risk from CHIKV. Arrivals from endemic countries have increased concurrently with vector incursions via imported goods, as well as via local movement from the Torres Strait to North Queensland ports. An outbreak of CHIKV could have a significant impact on health, the safety of the blood supply and on tourism. Case and vector surveillance as well as population health responses are crucial for minimising any potential impact of CHIKV establishment in Australia. This work is copyright.

Biobanking and Privacy in India.

Chaturvedi, Sachin; Srinivas, Krishna Ravi; Muthuswamy, Vasantha

2016-03-01

Biobank-based research is not specifically addressed in Indian statutory law and therefore Indian Council for Medical Research guidelines are the primary regulators of biobank research in India. The guidelines allow for broad consent and for any level of identification of specimens. Although privacy is a fundamental right under the Indian Constitution, courts have limited this right when it conflicts with other rights or with the public interest. Furthermore, there is no established privacy test or actionable privacy right in the common law of India. In order to facilitate biobank-based research, both of these lacunae should be addressed by statutory law specifically addressing biobanking and more directly addressing the accompanying privacy concerns. A biobank-specific law should be written with international guidelines in mind, but harmonization with other laws should not be attempted until after India has created a law addressing biobank research within the unique legal and cultural environment of India. © 2016 American Society of Law, Medicine & Ethics.

India's nuclear energy programme: prospects and challenges

Gupta, Arvind

2011-01-01

India has announced ambitious plans to expand its nuclear energy programme nearly 15 fold in the next 20 years, from the current 4,500 MWe to about 62,000 MWe by 2032. By 2020, India's Department of Atomic Energy (DAE) plans to install 20,000 MWe of nuclear power generation capacity (the fifth largest in the world). The department has plans beyond 2030 too. According to these plans India will have the capacity to produce 275 GWe (Giga Watt of electricity) of nuclear power by the year 2052. The DAE's projections are summarised. This is a truly ambitious plan. Without sufficient quantities of energy, India cannot hope to become a global power. Its dream of registering eight to nine per cent economic growth per annum will remain just that, a dream. Even with such ambitious plans on the nuclear energy front, the share of nuclear power in the overall energy mix will remain small. Currently nuclear energy constitutes only about three per cent of the total energy consumed in India. If the current projections are realised, the share of nuclear energy in the total energy output will still be about 20 per cent. India takes pride in its nuclear programme. Over the years, successive governments have fully supported the DAE's plans. This support is likely to continue in the future. In fact, following the Indo-US civil nuclear deal and the Nuclear Suppliers Group (NSG) waiver in 2008, the mood in India has turned upbeat. India is now getting integrated into the global nuclear regime even though it has not signed the Nuclear Non Proliferation Treaty (NNPT). The NSG waiver has, however, allowed India to enter into civil nuclear cooperation with several countries

Full Text Available Active growth of trade volume between India and Africa which has increased in twenty times since the beginning of the twenty-first century or in seventy times since 1991, certainly actualized a question of features of the modern Indo-African relations. In this regard the purpose of article is consideration of features of policy of India to the African countries. The author does the short historical review of the Indo-African relations, and considers key spheres of realization of modern regional strategy of India on the African continent - humanitarian projects, foreign trade and investments. The main methods of research are the comparative-historical approach and the statistical analysis, being used for identification of positive or negative dynamics of development of the Indo-African cooperation. Now the African region takes strategic significance for India. Rapid economic development of the African countries and increase in a standard of living of the population turn the continent into a perspective sales market of the Indian goods and services. Besides, India actively develops humanitarian projects and renders the financial help to many African countries. However, India faces set of problems and factors - geographical remoteness, the discrimination and racism, instability of political systems of many African countries and the African policy of China. The active economic policy of China on the African continent has compelled India to develop cooperation with the countries of Africa more actively. In recent years India also as well as China tries to make active and modernize the economic and humanitarian policy in Africa. Struggle for commodity markets of the goods and services in Africa makes Africa by strategic region not only in the Indo-Chinese relations, but in foreign policy of India as a whole.

Victimization and Human Immunodeficiency Virus-Related Risk Among Transgender Women in India: A Latent Profile Analysis.

Globally, transgender women (TGW) experience multiple forms of victimization such as violence and discrimination that can place them at risk for poor sexual health. To date, research overlooks the heterogeneity in experiences of victimization among TGW. Furthermore, few studies have examined the association between victimization and sexual risk among TGW in India, despite the high burden of HIV and victimization in this community. Latent profile analysis was performed to identify patterns of victimization in a convenience sample of 299 TGW recruited from nongovernmental organizations across four states in India. Analysis of covariance was performed to examine differences in sexual risk (i.e., alcohol use before sex; inconsistent condom use with a male regular partner, a male causal partner, and a male paying partner; and having multiple sexual partners) between latent profiles. Five distinct profiles of Indian TGW were identified based on the type and severity of victimization: (1) Low victimization, (2) High verbal police victimization, (3) High verbal and physical police victimization, (4) Moderate victimization, and (5) High victimization. While controlling for age, education, income, HIV status, and marital status, results revealed that TGW in the moderate victimization and high victimization profiles had higher sexual risk than TGW in the low victimization and high verbal police victimization profiles. In addition, TGW in high verbal and physical police victimization profile had higher sexual risk than TGW in low victimization profile. These findings underscore the importance of tailoring sexual risk reduction interventions to the specific needs of TGW based on patterns of victimization.

Full Text Available Context: Hand, foot, and mouth disease (HFMD remains a common problem in India, yet its etiology is largely unknown as diagnosis is based on clinical characteristics. There are very few laboratory-based molecular studies on HFMD outbreaks. Aim: The aim of this study was to characterize HFMD-related isolates by molecular techniques. Settings and Design: Between 2005 and 2008, during two documented HFMD outbreaks, 30 suspected HFMD cases presented at the Outpatient Unit of the Department of Dermatology, Christian Medical College (CMC, Vellore. Seventy-eight clinical specimens (swabs from throat, mouth, rectum, anus, buttocks, tongue, forearm, sole, and foot were received from these patients at the Department of Clinical Virology, CMC, for routine diagnosis of hand, foot, and mouth disease. Materials and Methods: Samples from these patients were cultured in Vero and rhabdomyosarcoma (RD cell lines. Isolates producing enterovirus-like cytopathogenic effect (CPE in cell culture were identified by a nested reverse transcription-based polymerase chain reaction (RT-PCR and sequenced. The nucleotide sequences were analyzed using the BioEdit sequence program. Homology searches were performed using the Basic Local Alignment Search Tool (BLAST algorithm. Statistical Analysis used: The statistical analysis was performed using Epi Info version 6.04b and Microsoft Excel 2002 (Microsoft Office XP. Results: Of the 30 suspected HFMD cases, only 17 (57% were laboratory confirmed and Coxsackievirus A16 (CVA16 was identified as the etiological agent in all these cases. Conclusions: Coxsackievirus A16 (CVA16 was identified as the virus that caused the HFMD outbreaks in Vellore between 2005 and 2008. Early confirmation of HFMD helps to initiate control measures to interrupt virus transmission. In the laboratory, classical diagnostic methods, culture and serological tests are being replaced by molecular techniques. Routine surveillance systems will help understand the

Nuclear programs in India and Pakistan

India and Pakistan launched their respective nuclear programs in the 1940s and 1950s with considerable foreign technical support, especially from the United States Atoms for Peace Program. The technology and training that was acquired served as the platform for later nuclear weapon development efforts that included nuclear weapon testing in 1974 and in 1998 by India, and also in 1998 by Pakistan - which had illicitly acquired uranium enrichment technology especially from Europe and received assistance from China. As of 2013, both India and Pakistan were continuing to produce fissile material for weapons, in the case of India also for nuclear naval fuel, and were developing a diverse array of ballistic and cruise missiles. International efforts to restrain the South Asian nuclear build-up have been largely set aside over the past decade as Pakistani support became central for the U.S. war in Afghanistan and as U.S. geopolitical and economic interests in supporting the rise of India, in part as a counter to China, led to India being exempted both from U.S non-proliferation laws and international nuclear trade guidelines. In the absence of determined international action and with Pakistan blocking the start of talks on a fissile material cutoff treaty, nuclear weapon programs in South Asia are likely to keep growing for the foreseeable future.

Critics of the recently negotiated 123 Nuclear Agreement between India and the United States of America often cite its retrograde effects on India's longstanding policy of non-alignment in foreign relations. The major part of this article will, therefore, is devoted to various aspects of DAE's performance, areas and problems that need more attention, their future plan on stepping up the production of nuclear energy by a big factor beyond their indigenous reach, and the consequent imperative and compulsion of opening the doors to the international market for bulk purchases. India's access to the international market for nuclear energy was barred because of our refusal to sign the nuclear non-proliferation treaty (NPT). Hence, when George Bush, ex-President of U.S.A., offered to sign a bilateral treaty with India, opening the door for nuclear and other strategic co-operation, the offer was welcome by the DAE and the Government of India with open arms. However, obligations under the rules of the International Atomic Energy Agency (IAEA), of which India is a member, still required applying to the Body for their approval so that India could approach the Consortium of nuclear supplier countries for their agreement to do business with India without raising any hindrance arising from NPT and Comprehensive Test Ban Treaty (CTBT)

Characterization of the influenza A H5N1 viruses of the 2008-09 outbreaks in India reveals a third introduction and possible endemicity.

Full Text Available Widespread infection of highly pathogenic avian influenza A H5N1 was reported from backyard and commercial poultry in West Bengal (WB, an eastern state of India in early 2008. Infection gradually spread to Tripura, Assam and Sikkim, the northeastern states, with 70 outbreaks reported between January 2008 and May 2009. Whole genome sequence analysis of three isolates from WB, one isolate from Tripura along with the analysis of hemagglutinin (HA and neuraminidase (NA genes of 17 other isolates was performed during this study. In the HA gene phylogenetic tree, all the 2008-09 Indian isolates belonged to EMA3 sublineage of clade 2.2. The closest phylogenetic relationship was found to be with the 2007-09 isolates from Bangladesh and not with the earlier 2006 and 2007 Indian isolates implying a third introduction into the country. The receptor-binding pocket of HA1 of two isolates from WB showed S221P mutation, one of the markers predicted to be associated with human receptor specificity. Two substitutions E119A (2 isolates of WB and N294S (2 other isolates of WB known to confer resistance to NA inhibitors were observed in the active site of neuraminidase. Several additional mutations were observed within the 2008-09 Indian isolates indicating genetic diversification. Overall, the study is indicative of a possible endemicity in the eastern and northeastern parts of the country, demanding active surveillance specifically in view of the critical mutations that have been observed in the influenza A H5N1 viruses.

The development and capacity of both India and Pakistan's nuclear weapons are described in production of weapon-grade materials, nuclear testing, weaponization engineering and delivery systems. India is capable of designing and manufacturing both small yield tactic nuclear weapons and big yield strategic ones and also possesses the technique to design and manufacture H-bombs. Weapon-grade plutonium constitutes the primary fission material for India's nuclear weapon and it has plutonium enough to make 70 to 100 nuclear weapons. India can also produce some tritium. India has already possessed delivery systems but it has not yet mounted nuclear warheads on its ballistic missiles even though its missiles, which India has already owned or is under development, have the ability to carry nuclear warheads. Pakistan also has the ability to make both tactic nuclear weapons and strategic ones. With its weapon-grade uranium, 20 to 30 nuclear weapons can be made. Besides the uranium production facility. Pakistan also has the facility to produce tritium. It is supposed that Pakistan has the ability to carry nuclear weapons with airplane, but it has a long way to go if it wants to mount nuclear weapon, especially bit yield ones, on its own missile. As a whole, India's nuclear force is stronger than Pakistan's, and its development far more advanced than Pakistan's

Several outbreaks of gout were reported in commercial broilers in India during 2011 and 2012, causing up to 40% mortality in the birds. Gross and histopathological observations confirmed gout. Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) analysis from kidney samples of gout-affected birds indicated the presence of chicken astrovirus (CAstV) in 41.7% of cases and a mixed infection of CAstV and avian nephritis virus (ANV) in 36.4% of cases. CAstV isolated from gout-affected kidneys by inoculating embryonated specific pathogen free (SPF) eggs showed dwarfing in embryos and a cytopathic effect in chicken embryo kidney cells. Inoculation of 1-day-old SPF and broiler chicks with CAstVs caused gout and mortality between 4 and 10 days post inoculation. Virus isolation and qRT-PCR analysis showed the presence of only CAstV in inoculated chicks. Sequence analysis of capsid genes indicated a major group of Indian CAstVs that displayed 92.0 to 99.2% intergroup amino acid identity and 83.9 to 90.4% identity with subgroup Bi CAstVs of UK origin. We designated this group Indian Bi. Analysis of the partial polymerase amino acid sequences of our isolates indicated two groups of CAstVs (Indian 1 and 2) that displayed 90.2 to 95.5% amino acid identity between them. We thus report for the first time that, in addition to infectious bronchitis virus and ANV, CAstVs are a causative agent of gout.

Energy sector reform in India : a review

International Nuclear Information System (INIS)

Aruna, M.; Raj, M.G.

2008-01-01

The government of India cannot afford to fund the total investment needed for restructuring the country's electric power sector. As such, India's Electricity Act of 2003 encouraged private participation to implement the required measures for efficient and optimum use of energy resources available in India and to supply quality power at the best cost to consumers. This paper described the present status of India's power sector with respect to generation, transmission and distribution of electricity. India's economy is growing at a faster rate compared to many other developing countries. It is expected that in the next 6 to 7 years additional capacity of 84,000 MW will be needed to meet the projected electricity demand. The Power Finance Corporation Limited (PFC) was established in 1986 in order to generate and provide funds for the power sector, which is in the process of reforms in every element of the electricity value chain. India is facing an energy deficit and peak power deficit of 8 per cent and 12.2 per cent, respectively. The inter-regional power transmission capacity is planned to be increased from 16,500 MW to 37,000 MW by 2012. Thermal and nuclear energy are major sources for electricity production in India. As most of these resources are non renewable, they must be efficiently used. Coal will continue to contribute about 60 per cent of power generation in India. It was concluded that a large capacity national power grid is necessary for inter-regional power transfer, and that Transmission Super Highways are needed for the development of a high capacity National Power Grid. 7 refs., 1 tab., 3 figs

AIDS in India: emerging from initial chaos.

Science.gov (United States)

Chatterjee, A

1991-01-01

India's response to AIDS has ranged from a 3-phase official surveillance program begun by the India Council of Medical Research (ICMR) in 1985, to legislation criticized as "bigoted and superficial", to conflicting messages, panic and confusion. The ICMR has determined that HIV is transmitted mainly by heterosexual contacts in India. In the media the Director-General of the ICMR was cited as recommending that sex with foreign visitors be banned, as a way to contain the HIV epidemic. Media also reported that defective ELISA screening kits were imported into India that infection control in some hospitals is sub-optimal, that the blood and blood products supply is grossly contaminated with HIV and that certain commercial blood donors were infected from giving blood. All foreign students currently must be HIV-negative to get a visa. It is a major problem to plan an AIDS education campaign with India's large illiterate population and dozens of languages. An AIDS network is emerging incorporating ICMR, the All India Institute of Medical Science, the Central Health Education Bureau, Mother Teresa's order, and a newly formed gay awareness group with the newsletter "Bombay Dost."

McLean, Thomas R

2009-06-01

With a lower cost for labour, Indian teleradiologists have an absolute price advantage in the global market. However, because trade is determined by comparative advantage rather than absolute price advantage, India's ability to export teleradiology services may be limited. The issue is, can the 'India price' for teleradiology set the price for these services in the USA? Review of the economic literature concerning the global teleradiology market. Currently, minimal information exists concerning the economic of global teleradiology market. However, a Ricardian analysis of this market suggests that India's ability to export teleradiology may be limited by rising opportunity costs (i.e. social unrest). Similarly, Heckscher-Ohlin analysis suggests that a lack of English-speaking physicians will limit India's ability to export teleradiology services to the USA. It appears unlikely that India will gain sufficient market share in the USA to determine the price of teleradiology services.

International nurse recruitment in India.

Khadria, Binod

2007-06-01

This paper describes the practice of international recruitment of Indian nurses in the model of a "business process outsourcing" of comprehensive training-cum-recruitment-cum-placement for popular destinations like the United Kingdom and United States through an agency system that has acquired growing intensity in India. Despite the extremely low nurse to population ratio in India, hospital managers in India are not concerned about the growing exodus of nurses to other countries. In fact, they are actively joining forces with profitable commercial ventures that operate as both training and recruiting agencies. Most of this activity is concentrated in Delhi, Bangalore, and Kochi. Gaps in data on nursing education, employment, and migration, as well as nonstandardization of definitions of "registered nurse," impair the analysis of international migration of nurses from India, making it difficult to assess the impact of migration on vacancy rates. One thing is clear, however, the chain of commercial interests that facilitate nurse migration is increasingly well organized and profitable, making the future growth of this business a certainty.

Migration from India to Australia.

"The article examines the contemporary trends and future prospects of migration from India to Australia. The focus is on Indian Settlers and Temporary Entrants admitted to Australia for employment and Indian students admitted to Australia for higher studies. The volume of emigration for permanent residence during the early 1990s has made India one of the leading source countries of migration to Australia. A majority of Indians admitted as Settlers every year join the labor force. Recent data indicate that, among Indian Settlers, there is a preponderance of unsponsored Independent Skilled Migrants. Given the anticipated growth in the number of Indian students, the coming years are likely to witness a spurt in Skilled Temporary Workers from India." excerpt

N-methylisatin-beta-thiosemicarbazone derivative (SCH 16 is an inhibitor of Japanese encephalitis virus infection in vitro and in vivo

Directory of Open Access Journals (Sweden)

Sriram D

2008-05-01

Full Text Available Abstract Background During the early and mid part of 20th century, several reports described the therapeutic effects of N-methylisatin-β-Thiosemicarbazone (MIBT against pox viruses, Maloney leukemia viruses and recently against HIV. However, their ability to inhibit flavivirus replication has not been investigated. Hence the present study was designed to evaluate the antiviral activity of 14 MIBT derivatives against Flaviviruses that are prevalent in India such as Japanese Encephalitis Virus (JEV, Dengue-2 (Den-2 and West Nile viruses (WNV. Results Amongst the fourteen Mannich bases of MIBT derivatives tested one compound – SCH 16 was able to completely inhibit in vitro Japanese encephalitis virus (JEV and West Nile virus (WNV replication. However no antiviral activity of SCH 16 was noted against Den-2 virus replication. This compound was able to inhibit 50% of the plaques (IC50 produced by JEV and WNV at a concentration of 16 μgm/ml (0.000025 μM and 4 μgm/ml (0.000006 μM respectively. Furthermore, SCH 16 at a concentration of 500 mg/kg body weight administered by oral route twice daily was able to completely (100% prevent mortality in mice challenged with 50LD50 JEV by the peripheral route. Our experiments to understand the mechanism of action suggest that SCH 16 inhibited JEV replication at the level of early protein translation. Conclusion Only one of the 14 isatin derivatives -SCH 16 exhibited antiviral action on JEV and WNV virus infection in vitro. SCH 16 was also found to completely inhibit JEV replication in vivo in a mouse model challenged peripherally with 50LD50 of the virus. These results warrant further research and development on SCH 16 as a possible therapeutic agent.

From Hair in India to Hair India.

Trüeb, Ralph M

2017-01-01

In all cultures, human hair and hairdo have been a powerful metaphor. Tracing back the importance and significance of human hair to the dawn of civilization on the Indian subcontinent, we find that all the Vedic gods are depicted as having uncut hair in mythological stories as well as in legendary pictures. The same is true of the Hindu avatars, and the epic heroes of the Ramayana, and the Mahabharata. Finally, there are a number of hair peculiarities in India pertinent to the creed and religious practices of the Hindu, the Jain, and the Sikh. Shiva Nataraja is a depiction of the Hindu God Shiva as the cosmic dancer who performs his divine dance as creator, preserver, and destroyer of the universe and conveys the Indian conception of the never-ending cycle of time. The same principle manifests in the hair cycle, in which perpetual cycles of growth, regression, and resting underly the growth and shedding of hair. Finally, The Hair Research Society of India was founded as a nonprofit organisation dedicated to research and education in the science of hair. Notably, the HRSI reached milestones in the journey of academic pursuit with the launch of the International Journal of Trichology, and with the establishment of the Hair India conference. Ultimately, the society aims at saving the public from being taken for a ride by quackery, and at creating the awareness that the science of hair represents a subspecialty of Dermatology. In analogy again, the dwarf on which the Nataraja dances represents the demon of egotism, and thus symbolizes Shiva's, respectively, the HRSI's victory over ignorance.

Is India the Exception?

India is still the extreme under-achiever in international sport competitions. Whereas in China high growth rates have been accompanied by a huge improvement in its ranking in international sport events a similar impact of extraordinary growth rates is seemingly totally absent in the case of India....... Is India an exception? Several econometric studies have shown that income per capita is a significant variable explaining elite sport results such as results in the Olympic Games. From this stylized fact follows the hypothesis that 'above/below average' growth rates lead to relative improvements...... between growth in GNP per capita and growth in medal points (no. 1: five points, no. 2: three points, no.3: two points) in Olympic Summer Games. The findings show no correlation and in a few calculations a very weak correlation. Among the countries behaving in accordance with the hypothesis in the most...

Environmental and ecosystem studies have assumed greater relevance in the last decade of the twentieth century than even before. The urban settlements are becoming over-crowded and industries are increasingly polluting the air, water and sound in our larger metropolises. Degradation of different types of ecosystem are discussed in this book, Ecosystem Degradation in India. The book has been divided into seven chapters: Introduction, Coastal and Delta Ecosystem, River Basin Ecosystem, Mountain Ecosystem, Forest Ecosystem, Urban Ecosystem and the last chapter deals with the Environmental Problems and Planning. In the introduction the environmental and ecosystem degradation problems in India is highlighted as a whole while in other chapters mostly case studies by experts who know their respective terrain very intimately are included. The case study papers cover most part of India and deal with local problems, stretching from east coast to west coast and from Kashmir to Kanyakumari. (author)

Nuclear power in India

International Nuclear Information System (INIS)

Bose, D.K.

1980-01-01

India has now nine years of experience with her in nuclear power generation. The system has been acclaimed on various grounds by the authority concerned with its organization in the country. The present paper intends to examine critically the claim for economic superiority of the nuclear power over the thermal power which is asserted often by the spokesmen for the former. Information about the cost of nuclear power that is available to researchers in India is very meagre. Whatever appears in official publications is hardly adequate for working out reasonable estimates for scrutiny. One is therefore left to depend on the public statements made by dignitaries from time to time to form an idea about the economics of nuclear power. Due to gaps in information we are constrained to rely on the foreign literature and make careful guesses about possible costs applicable to India

Female feticide in India.

Science.gov (United States)

Ahmad, Nehaluddin

2010-01-01

Women are murdered all over the world. But in India a most brutal form of killing females takes place regularly, even before they have the opportunity to be born. Female feticide--the selective abortion of female fetuses--is killing upwards of one million females in India annually with far-ranging and tragic consequences. In some areas, the sex ratio of females to males has dropped to less than 8000:1000. Females not only face inequality in this culture, they are even denied the right to be born. Why do so many families selectively abort baby daughters? In a word: economics. Aborting female fetuses is both practical and socially acceptable in India. Female feticide is driven by many factors, but primarily by the prospect of having to pay a dowry to the future bridegroom of a daughter. While sons offer security to their families in old age and can perform the rites for the souls of deceased parents and ancestors, daughters are perceived as a social and economic burden. Prenatal sex detection technologies have been misused, allowing the selective abortions of female offspring to proliferate. Legally, however, female feticide is a penal offence. Although female infanticide has long been committed in India, feticide is a relatively new practice, emerging concurrently with the advent of technological advancements in prenatal sex determination on a large scale in the 1990s. While abortion is legal in India, it is a crime to abort a pregnancy solely because the fetus is female. Strict laws and penalties are in place for violators. These laws, however, have not stemmed the tide of this abhorrent practice. This article will discuss the socio-legal conundrum female feticide presents, as well as the consequences of having too few women in Indian society.

2011-12-01

Full Text Available Abstract Background Studies have demonstrated the significance of commercial sex work in the ongoing transmission of HIV and other sexually transmitted infections (STIs in India. Clients of female sex workers (FSWs are thought to be an important bridging population for HIV/STIs. However, there is a lack of information on basic characteristics of sex work clients. This study sought to describe the prevalence of HIV and other STIs, as well as examine the determinants of these pathogens among a sample of clients in south India. Methods Data were from a cross-sectional biological and behavioural survey of FSW clients from six districts in Karnataka State, India. The prevalence of HIV, syphilis, herpes simplex virus type 2 (HSV-2, chlamydia (CT and gonorrhoea (NG among clients was examined. Multivariable logistic regression models were used to analyse the socio-demographic, sexual behaviour and sex-work related characteristics related to the prevalence of each pathogen. Sampling weights and appropriate survey methods were utilized in regression models to account for complex sampling design. Results The total sample size was 2,745. The average age of clients was 30.4 (SE:0.3. Across the total sample, the prevalence of HIV, HSV-2, syphilis and CT/NG was 5.6%, 28.4%, 3.6% and 2.2%, respectively. The prevalence of HIV/STIs varied substantially across districts, reaching statistical significance for HIV (p Conclusions This study fills in important gaps in knowledge regarding clients in southern India. The strong association between HIV and HSV-2 infections highlights the complications in designing effective prevention, intervention and management programs of this well-hidden population.

Reorienting India's financial system: In conversation with Dr Duvvuri Subbarao, Governor, Reserve Bank of India

Directory of Open Access Journals (Sweden)

Vivek Moorthy

2012-06-01

Full Text Available Confronted by a slowing economy, the Reserve Bank of India has undertaken steps to revive it. These measures, however, run the risk of worsening current high levels of inflation. This paper examines certain aspects of India's financial system that have contributed to this situation. It argues that unduly low yields on Government bonds have prevented a healthy financial system from developing, with adverse impact upon inflation and other macroeconomic outcomes. It suggests that India should focus far more on domestic, and less on external, financial liberalisation. Specifically, yields on non-market borrowing, such as Provident Fund deposits, should be benchmarked to a low frequency measure of consumer price inflation.

Data on the renal safety of Tenofovir (TDF) in Low and Middle Income Countries (LMICs) is scarce. We compared development of various forms of renal impairment with use of TDF-containing antiretroviral therapy (ART) between a cohort from the Institute of Infectious Diseases (IID) Pune, Western India and the Royal Free Hospital (RFH) London, UK. This is a retrospective analysis of change in estimated glomerular filtration rates (eGFRs) at 6, 12 and 24 months post TDF initiation using the Modification of Diet in Renal Disease (MDRD) equation. In people living with Human Immunodeficiency virus (PLHIV) with pre-TDF eGFR > 90 ml/min/1.73 m2 time to development of and factors associated with progression to eGFR  90 ml/min/1.73 m2 PLHIV at IID were more likely to develop an eGFR < 60 ml/min/1.73 m2 (aHR = 7.6 [95% CI 3.4, 17.4] p < 0.0001) and had a faster rate of progression estimated using Kaplan Meier methods. Risk factors included age (per 10 years older: aHR = 2.21 [1.6, 3.0] p < 0.0001) and receiving concomitant ritonavir boosted Protease Inhibitor (PI/r) (aHR = 2.4 [1.2, 4.8] p = 0.01). There is higher frequency of treatment limiting renal impairment events amongst PLHIV receiving TDF in Western India. As TDF scale up progresses, programs need to develop capacity for monitoring and treatment of renal impairment associated with TDF.

Varicella zoster virus infection of the central nervous system – 10 year experience from a tertiary hospital in South India

2017-01-01

Full Text Available Introduction: Varicella zoster virus is an exclusively human neurotrophic virus. The primary infection with the virus causes varicella. The virus remains latent in nervous tissue and upon secondary activation causes a variety of syndromes involving the central nervous system (CNS including meningoencephalitis and cerebellitis. Materials and Methods: In this study, we looked at the epidemiology, clinical and laboratory features, and outcomes of patients who were admitted with varicella zoster of the CNS from 2005 to 2014. Results: There were 17 patients. Fever was present in 13 patients, seizures in 9 patients and headache and vomiting in 4 patients each. A generalized varicella rash was present in 8 out of 17 patients. A single dermatomal herpes zoster was present in seven patients. Two patients had no rash. Varicella zoster polymerase chain reaction (PCR in cerebrospinal fluid (CSF was done in 5 patients of which 4 were positive and 1 was negative. Nine patients had diabetes with an average glycated hemoglobin of 8.6%. Total number of deaths was five. Conclusions: Patients with diabetes who develop varicella or herpes zoster may be at risk for CNS complications. The diagnosis of varicella encephalitis has to rest on a combination of clinical findings and CSF PCR, as neither the rash nor the PCR is sensitive enough to diagnose all the cases with varicella encephalitis.

Thapa, S; Prasad, C V; Rao, P H; Severy, L J; Rao, S R

1994-01-01

Contraceptive social marketing is a way of supplying contraceptives to consumers who cannot afford to buy them at full market price, yet are not reached by the free public distribution program. The process involves supplying a subsidized product through existing commercial distribution networks, using the mass media and other retail marketing techniques to commercially advertise the products. India was the first country to introduce this concept to its family planning program. India's social marketing program is also the largest in the world. Over the past 25 years, total condom sales in India have expanded under the program from less than 10 million per year to more than one billion. The authors present an overview of India's social marketing initiative, describe the firms participating in the program, and summarize the lessons learned from the social marketing experience. Problems and prospects, and experiences and implications are discussed.

Teleradiology is yet to take off in India. This is unfortunate since this technology is ideal for a country like India, where expertise in remote areas for advanced investigations such as CT and MR, is lacking. We were the first center in India to use teleradiology on a regular basis. Our initial methodology in 1996 was using video-capture cards and Windows 95 dial-up protocols. Now we use DICOM transfers and remote-access software. Even today, 4 years later, we are the only center in India using teleradiology on a regular basis.

Paramyxoviruses and other negative-strand RNA viruses encode matrix proteins that coordinate the virus assembly process. The matrix proteins link the viral glycoproteins and the viral ribonucleoproteins at virus assembly sites and often recruit host machinery that facilitates the budding process. Using a co-affinity purification strategy, we have identified the beta subunit of the AP-3 adapter protein complex, AP3B1, as a binding partner for the M proteins of the zoonotic paramyxoviruses Nipah virus and Hendra virus. Binding function was localized to the serine-rich and acidic Hinge domain of AP3B1, and a 29-amino-acid Hinge-derived polypeptide was sufficient for M protein binding in coimmunoprecipitation assays. Virus-like particle (VLP) production assays were used to assess the relationship between AP3B1 binding and M protein function. We found that for both Nipah virus and Hendra virus, M protein expression in the absence of any other viral proteins led to the efficient production of VLPs in transfected cells, and this VLP production was potently inhibited upon overexpression of short M-binding polypeptides derived from the Hinge region of AP3B1. Both human and bat (Pteropus alecto) AP3B1-derived polypeptides were highly effective at inhibiting the production of VLPs. VLP production was also impaired through small interfering RNA (siRNA)-mediated depletion of AP3B1 from cells. These findings suggest that AP-3-directed trafficking processes are important for henipavirus particle production and identify a new host protein-virus protein binding interface that could become a useful target in future efforts to develop small molecule inhibitors to combat paramyxoviral infections. Henipaviruses cause deadly infections in humans, with a mortality rate of about 40%. Hendra virus outbreaks in Australia, all involving horses and some involving transmission to humans, have been a continuing problem. Nipah virus caused a large outbreak in Malaysia in 1998, killing 109 people

Forest management in India. Local versus state control of forest resources

Wilk, J

1998-12-31

Degradation and substantial losses to India`s forests have prompted a change in existing forestry management strategy. The new approach includes recognition of local participation in forestry management schemes but state control over most decisions is still dominant. Seen in terms of a common property resource system, India`s forests lack many of the factors usually considered inherent to successful management programs. Though India`s latest Forest Act affords more local involvement in forestry management, there continues to be an apparent lack of rights for local management groups over decision-making and the resource itself. Can this system enable the required balance between state and local management of India`s forests? 24 refs, 1 tab

Cost-effectiveness of hepatitis C treatment using generic direct-acting antivirals available in India.

Directory of Open Access Journals (Sweden)

Rakesh Aggarwal

Full Text Available Availability of directly-acting antivirals (DAAs has changed the treatment landscape of hepatitis C virus (HCV infection. The high price of DAAs has restricted their use in several countries. However, in some countries such as India, generic DAAs are available at much cheaper price. This study examined whether generic DAAs could be cost-saving and how long it would take for the treatment to become cost-saving/effective.A previously-validated, mathematical model was adapted to the HCV-infected population in India to compare the outcomes of no treatment versus treatment with DAAs. Model parameters were estimated from published studies. Cost-effectiveness of HCV treatment using available DAAs was calculated, using a payer's perspective. We estimated quality-adjusted life years (QALYs, disability-adjusted life years (DALYs, total costs, and incremental cost-effectiveness ratio of DAAs versus no treatment. One-way and probabilistic sensitivity analyses were conducted.Compared with no treatment, the use of generic DAAs in Indian HCV patients would increase the life expectancy by 8.02 years, increase QALYs by 3.89, avert 19.07 DALYs, and reduce the lifetime healthcare costs by $1,309 per-person treated. Treatment became cost-effective within 2 years, and cost-saving within 10 years of its initiation overall and within 5 years in persons with cirrhosis. Treating 10,000 HCV-infected persons could prevent 3400-3850 decompensated cirrhosis, 1800-2500 HCC, and 4000-4550 liver-related deaths. The results were sensitive to the costs of DAAs, pre- and post-treatment diagnostic tests and management of cirrhosis, and quality of life after sustained virologic response.Treatment with generic DAAs available in India will improve patient outcomes, provide a good value for money within 2 years, and be ultimately cost-saving. Therefore, in this and similar settings, HCV treatment should be a priority from a public health as well an economic perspective.

Transmission of Hepatitis E Virus in Developing Countries

Directory of Open Access Journals (Sweden)

Full Text Available Hepatitis E virus (HEV, an RNA virus of the Hepeviridae family, has marked heterogeneity. While all five HEV genotypes can cause human infections, genotypes HEV-1 and -2 infect humans alone, genotypes HEV-3 and -4 primarily infect pigs, boars and deer, and genotype HEV-7 primarily infects dromedaries. The global distribution of HEV has distinct epidemiological patterns based on ecology and socioeconomic factors. In resource-poor countries, disease presents as large-scale waterborne epidemics, and few epidemics have spread through person-to-person contact; however, endemic diseases within these countries can potentially spread through person-to-person contact or fecally contaminated water and foods. Vertical transmission of HEV from infected mother to fetus causes high fetal and perinatal mortality. Other means of transmission, such as zoonotic transmission, can fluctuate depending upon the region and strain of the virus. For instance, zoonotic transmission can sometimes play an insignificant role in human infections, such as in India, where human and pig HEV infections are unrelated. However, recently China and Southeast Asia have experienced a zoonotic spread of HEV-4 from pigs to humans and this has become the dominant mode of transmission of hepatitis E in eastern China. Zoonotic HEV infections in humans occur by eating undercooked pig flesh, raw liver, and sausages; through vocational contact; or via pig slurry, which leads to environmental contamination of agricultural products and seafood. Lastly, blood transfusion-associated HEV infections occur in many countries and screening of donors for HEV RNA is currently under serious consideration. To summarize, HEV genotypes 1 and 2 cause epidemic and endemic diseases in resource poor countries, primarily spreading through contaminated drinking water. HEV genotypes 3 and 4 on the other hand, cause autochthonous infections in developed, and many developing countries, by means of a unique zoonotic

The growing middle class in India, coupled with a need for electricity to provide basic services to the masses, provides an opportunity to deploy photovoltaic systems in cost-effective applications ranging from grid-connected to isolated location requirements. This need is being satisfied by aggressive government programs, the availability of funds from agencies such as the World Bank, and the desire of Indian industries to form joint ventures for in-country manufacturing. The relaxed restrictions on doing business in India makes today's opportunities timely indeed.

Cross-subsidy in electricity tariffs: evidence from India

International Nuclear Information System (INIS)

Chattopadhyay, P.

2004-01-01

The recent reforms in India have been equated to the reduction of cross-subsidization in electricity tariffs. Examining the usefulness of cross subsidies in electricity tariffs in India, I have argued that they are prone to considerable inefficiencies and should be discontinued. I have also formally examined the viability of above-cost tariffs in the industrial sector to allow subsidized domestic and agricultural consumption. Finally, I have used data from a distribution company in the state of Uttar Pradesh, India to estimate industrial demand for electricity and have found that the policy of cross-subsidy may have indeed gone overboard in India.

The Ayurvedic Pharmacopoeia of India (API) is a unique book of standards describing the quality, purity and strength of selected drugs that are manufactured, distributed, and sold by the licensed manufacturers in pan India. It is developed in two parts; the part one comprises of mono-monographs of medicinal substances of natural origin and part two includes selected compound formulations sourced from the schedule - I books under the Drugs and Cosmetics Act, 1940 comprising of popular Ayurvedic classics of different period of times. The first part of the Ayurvedic Formulary of India was published in 1978 and thereafter, the Ayurvedic Pharmacopoeia of India (mono-monograph) Part-I, Vol. I was published in the year 1989 and subsequently, the other volumes were published with their legalized status under Drugs and Cosmetics Act, 1940. The study was aimed to bring out the existing knowledge on the Ayurvedic pharmacopoeia with its chronological development reviewed from the ancient Vedic Compendia with its continuum in Ayurvedic classics of different period of time till recent past. A literary search based on the ancient origin of Ayurveda was carried out. The drug making from the natural resources and utility of the knowledge exist in classical Ayurvedic works of different period of time till composition of the Ayurvedic Pharmacopoeia of India and its importance as official documents of Govt. of India for Standards of Ayurvedic Drugs and its perspectives have been discussed. The present paper reviews on the systemic development and different aspects of drug-making (Pharmacopoeia) with evidence lying in the 5000 years old work of India. During the systematic review of the various works of different period of times (ancient, medieval and modern), it was found that the Ayurvedic Pharmacopoeia of India has its development during 20th Century as an official document of Govt. of India comprising of single drugs monograph and compound formulations.

Rifting to India-Asia Reactivation: Multi-phase Structural Evolution of the Barmer Basin, Rajasthan, northwest India

The Barmer Basin, situated within the West Indian Rift System, is an intra-cratonic rift basin produced during Gondwana break-up. Despite being a prominent oil and gas province, the structural evolution and context of the rift within northwest India remains poorly understood. Substantial subsurface datasets acquired during hydrocarbon exploration provide an unrivalled tool to investigate the tectonic evolution of the Barmer Basin rift and northwest India during India-Asia collision. Here we present a structural analysis using seismic datasets to investigate Barmer Basin evolution and place findings within the context of northwest India development. Present day rift structural architectures result from superposition of two non-coaxial extensional events; an early mid-Cretaceous rift-oblique event (NW-SE), followed by a main Paleocene rifting phase (NE-SW). Three phases of fault reactivation follow rifting: A transpressive, Late Paleocene inversion along localised E-W and NNE-SSW-trending faults; a widespread Late Paleocene-Early Eocene inversion and Late Miocene-Present Day transpressive strike-slip faulting along NW-SE-trending faults and isolated inversion structures. A major Late Eocene-Miocene unconformity in the basin is also identified, approximately coeval with those identified within the Himalayan foreland basin, suggesting a common cause related to India-Asia collision, and calling into question previous explanations that are not compatible with spatial extension of the unconformity beyond the foreland basin. Although, relatively poorly age constrained, extensional and compressional events within the Barmer Basin can be correlated with regional tectonic processes including the fragmentation of Gondwana, the rapid migration of the Greater Indian continent, to subsequent collision with Asia. New insights into the Barmer Basin development have important implications not only for ongoing hydrocarbon exploration but the temporal evolution of northwest India.

India's tourism industry generated 6.6% of the nation's Gross Domestic Product (GDP) during 2012. International travel to India is predicted to grow at an average annual rate of ∼ 8% over the next decade. The number of foreign tourists has increased by 9% to 5.8 million. Approximately 8% of travelers to developing countries require medical care during or after travel; the main diagnoses are vaccine-preventable diseases. Travelers to India can be exposed to various infectious diseases; water-borne, water-related, and zoonotic diseases may be imported to India where the disease is not endemic. The World Health Organization (WHO) emphasizes that all international travelers should be up to date with routine vaccinations. The recommended vaccinations for travelers to India vary according to the traveler's age, immunization history, existing medical conditions, duration, legal requirements for entry into countries being visited, travelers preferences, and values. Travelers should consult with a doctor so that there is sufficient time for completion of optimal vaccination schedules. No matter where traveling, one should be aware of potential exposure to certain organisms that can cause severely illnesses, even death. There is no doubt that vaccines have reduced or virtually eliminated many diseases that killed or severely disabled children and adults just a few generations ago. Thus, travelers must take recommended vaccines per schedule before traveling to India.

Multiple sclerosis (MS) 1 is a chronic neurodegenerative disease involving destruction of the myelin sheath around axons of the brain, spinal cord and optic nerve. There has been a tremendous transformation in its perspective across globe. In recent years, its prevalence has changed dramatically worldwide and India is no exception. Initially, MS was believed to be more common in the Caucasians of Northern Europe and United States; however, it has been found to be present in Indian subcontinent as well. There has been a considerable shift in MS prevalence in India and this has really changed the notion of considering India as a low risk zone for MS. In this review, a concise overview and latest update on changing scenario of MS in India is presented along with some major challenges regarding it persisting across globe even today. In India, remarkable upsurge is needed in carrying out large scale population-based epidemiological studies to get an idea about the true incidence and prevalence rates of MS viz a viz disease burden. Through this review, we have probably tried to identify the actual picture of MS prevalence in India and this could serve as harbinger for upcoming research and at the same time it would definitely aid in working out future strategies for MS management in the country.

However, due to poor coverage and utilization of services by truckers in the initial 18-month period, the intervention was redesigned to focus on only 17 trans-shipment locations. The redesigned intervention model was based on the McDonald's business franchise model where the focus is on optimal placement of services, supported with branding and standardization of services offered, and a surround sound communication approach. Program output indicators were assessed using program monitoring data over 7 years (2004–2010 and two rounds of cross-sectional behavioral surveys conducted in January 2008 (n = 1402 and July 2009 (n = 1407.Results: The number of truckers contacted per month per site increased from 374 in 2004 to 4327 in 2010. Analysis of survey data showed a seven-fold increase in clinic visits in the past 12 months from 2008 to 2009 (21% versus 63%, P < 0.001.

India, the second most populated country of the world with a population of 1.027 billion, is a country of contrasts. It is characterized as one of the world's largest industrial nations, yet most of the negative characteristics of poor and developing countries define India too. The population is predominantly rural, and 36% of people still live below poverty line. There is a continuous migration of rural people into urban slums creating major health and economic problems. India is one of the pioneer countries in health services planning with a focus on primary health care. Improvement in the health status of the population has been one of the major thrust areas for social development programmes in the country. However, only a small percentage of the total annual budget is spent on health. Mental health is part of the general health services, and carries no separate budget. The National Mental Health Programme serves practically as the mental health policy. Recently, there was an eight-fold increase in budget allocation for the National Mental Health Programme for the Tenth Five-Year Plan (2002-2007). India is a multicultural traditional society where people visit religious and traditional healers for general and mental health related problems. However, wherever modern health services are available, people do come forward. India has a number of public policy and judicial enactments, which may impact on mental health. These have tried to address the issues of stigma attached to the mental illnesses and the rights of mentally ill people in society. A large number of epidemiological surveys done in India on mental disorders have demonstrated the prevalence of mental morbidity in rural and urban areas of the country; these rates are comparable to global rates. Although India is well placed as far as trained manpower in general health services is concerned, the mental health trained personnel are quite limited, and these are mostly based in urban areas.

The chrysanthemum is one of popular flowers in the world and a host for several viruses. So far, molecular interaction studies between the chrysanthemum and viruses are limited. In this study, we carried out a transcriptome analysis of chrysanthemum in response to three different viruses including Cucumber mosaic virus (CMV), Tomato spotted wilt virus (TSWV) and Potato virus X (PVX). A chrysanthemum 135K microarray derived from expressed sequence tags was successfully applied for the expression profiles of the chrysanthemum at early stage of virus infection. Finally, we identified a total of 125, 70 and 124 differentially expressed genes (DEGs) for CMV, TSWV and PVX, respectively. Many DEGs were virus specific; however, 33 DEGs were commonly regulated by three viruses. Gene ontology (GO) enrichment analysis identified a total of 132 GO terms, and of them, six GO terms related stress response and MCM complex were commonly identified for three viruses. Several genes functioning in stress response such as chitin response and ethylene mediated signaling pathway were up-regulated indicating their involvement in establishment of host immune system. In particular, TSWV infection significantly down-regulated genes related to DNA metabolic process including DNA replication, chromatin organization, histone modification and cytokinesis, and they are mostly targeted to nucleosome and MCM complex. Taken together, our comparative transcriptome analysis revealed several genes related to hormone mediated viral stress response and DNA modification. The identified chrysanthemums genes could be good candidates for further functional study associated with resistant to various plant viruses.

India-Australia energy cooperation: the road ahead

Energy ties between India and Australia are centuries old and can be traced back to the days of East India Company of the British-Indian era. From the first commercial export in the form of a shipment of coal to India from Australia in 1797, energy cooperation has come a long way. For instance, apart from making unswerving attempts to get Australian yellowcake, attempts have been made by India to ensure greater supply of coal and natural gas. Both the countries are also trying to find ways and means to work jointly on increasing the production of geo-thermal and solar energy as also to enhance clean-energy technology cooperation among other things. Energy forms the core of a nation's national security as a country's economy is fuelled by energy resources and India is no exception in this respect. It holds a prime position as the Indian economy has been growing at a rate of six to seven per cent in the past few years. There is no denying that India has come a long way since independence in the energy sector. However greater levels of consumption, both industrial and domestic have led to a stage where the supply of energy falls short of the demand. The main focus of the government of late has been on capacity-building of the economy. Energy-intensive projects such as infrastructure development are the top priorities of the government; something which had been neglected in most parts of independent India. And this is where the importance of Australia for India lies, given its abundant energy resources. Indian companies are interested in investing in coal mining and oil and gas exploration in Australia. The five action plans that were signed in November 2008 with the Ministries of Power, Coal, Petroleum and Natural Gas, Mines, and New and Renewable Energy are the buildings blocks to build on and to take forward the bilateral engagement in the energy sector

British India was an important site of much important malaria research. Although Ronald Ross left India in 1899, a number of malariologists continued the task of evaluating the incidence and distribution of malaria in the country. Implementing practical solutions was hampered by formidable social and economic problems. This paper examines the Indian situation in the late 1920s, through a retrospective selection of writings chosen by J.A. Sinton for reproduction in an early issue of 'The records of the malaria survey of India', and the analysis of the Indian malaria situation through a visit of the League of Nations Malaria Commission in 1929.

The North-South divide in snake bite envenomation in India

Directory of Open Access Journals (Sweden)

Vivek Chauhan

2016-01-01

Full Text Available Snake bite envenomations are common in rural areas and the incidence peaks during monsoons in India. Prominent venomous species have been traditionally labeled as the ′big four′ that includes Cobra, Krait, Russel′s viper and Saw scaled viper. Systematic attempts for identification and classification of prevalent snakes in various states of India are missing till now and there is no concrete data on this aspect. The published literature however shows that some species of snakes are more prevalent in a particular region than the other parts of India e.g. Saw scaled vipers in Rajasthan. We reviewed the published literature from various parts of India and found that there is a North-South divide in the snake bite profile from India. Neurotoxic envenomations are significantly higher in North India compared to South India where Hematotoxic envenomations are prevalent. Russel′s viper causes local necrosis, gangrene and compartment syndrome. These manifestations have never been reported in North Indian snake bite profile in the published literature. Early morning neuroparalysis caused by Krait is a common problem in North India leading to high mortality after snake bite. This review presents supporting evidence for the North-South divide and proposes a way forward in formulation and revision of guidelines for snake bite in India.

Nuclear fuel cycle assessment of India: A technical study for U.S.-India cooperation

Science.gov (United States)

Krishna, Taraknath Woddi Venkat

The recent civil nuclear cooperation proposed by the Bush Administration and the Government of India has heightened the necessity of assessing India's nuclear fuel cycle inclusive of nuclear materials and facilities. This agreement proposes to change the long-standing U.S. policy of preventing the spread of nuclear weapons by denying nuclear technology transfer to non-NPT signatory states. The nuclear tests in 1998 have convinced the world community that India would never relinquish its nuclear arsenal. This has driven the desire to engage India through civilian nuclear cooperation. The cornerstone of any civilian nuclear technological support necessitates the separation of military and civilian facilities. A complete nuclear fuel cycle assessment of India emphasizes the entwinment of the military and civilian facilities and would aid in moving forward with the separation plan. To estimate the existing uranium reserves in India, a complete historical assessment of ore production, conversion, and processing capabilities was performed using open source information and compared to independent reports. Nuclear energy and plutonium production (reactor- and weapons-grade) was simulated using declared capacity factors and modern simulation tools. The three-stage nuclear power program entities and all the components of civilian and military significance were assembled into a flowsheet to allow for a macroscopic vision of the Indian fuel cycle. A detailed view of the nuclear fuel cycle opens avenues for technological collaboration. The fuel cycle that grows from this study exploits domestic thorium reserves with advanced international technology and optimized for the existing system. To utilize any appreciable fraction of the world's supply of thorium, nuclear breeding is necessary. The two known possibilities for production of more fissionable material in the reactor than is consumed as fuel are fast breeders or thermal breeders. This dissertation analyzes a thermal

Studies have demonstrated the significance of commercial sex work in the ongoing transmission of HIV and other sexually transmitted infections (STIs) in India. Clients of female sex workers (FSWs) are thought to be an important bridging population for HIV/STIs. However, there is a lack of information on basic characteristics of sex work clients. This study sought to describe the prevalence of HIV and other STIs, as well as examine the determinants of these pathogens among a sample of clients in south India. Data were from a cross-sectional biological and behavioural survey of FSW clients from six districts in Karnataka State, India. The prevalence of HIV, syphilis, herpes simplex virus type 2 (HSV-2), chlamydia (CT) and gonorrhoea (NG) among clients was examined. Multivariable logistic regression models were used to analyse the socio-demographic, sexual behaviour and sex-work related characteristics related to the prevalence of each pathogen. Sampling weights and appropriate survey methods were utilized in regression models to account for complex sampling design. The total sample size was 2,745. The average age of clients was 30.4 (SE:0.3). Across the total sample, the prevalence of HIV, HSV-2, syphilis and CT/NG was 5.6%, 28.4%, 3.6% and 2.2%, respectively. The prevalence of HIV/STIs varied substantially across districts, reaching statistical significance for HIV (plodges were at increased risk for CT/NG (AOR: 6.3; 95%CI: 1.9-20.6, p=.03). Examining co-infections, clients with HSV-2 infections were at substantially higher risk of being HIV-positive (AOR: 10.4; 95%CI: 6.1-17.7, p<.0001). This study fills in important gaps in knowledge regarding clients in southern India. The strong association between HIV and HSV-2 infections highlights the complications in designing effective prevention, intervention and management programs of this well-hidden population.

History of Cardiology in India

Full Text Available History as a science revolves around memories, travellers' tales, fables and chroniclers' stories, gossip and trans-telephonic conversations. Medicine itself as per the puritan's definition is a non-exact science because of the probability-predictability-sensitivity-specificity factors. Howsoever, the chronicles of Cardiology in India is quite interesting and intriguing. Heart and circulation was known to humankind from pre-Vedic era. Various therapeutics measures including the role of Yoga and transcendental meditation in curing cardiovascular diseases were known in India. Only recently there has been resurgence of the same globally. There have been very few innovations in Cardiology in India. The cause of this paucity possibly lie in the limited resources. This has a vicious effect on the research mentality of the population who are busy in meeting their daily requirements. This socio-scientific aspect needs a thorough study and is beyond the scope of the present documentation. Present is the future of past and so one must not forget the history which is essentially past that give the present generation the necessary fulcrum to stand in good stead. The present article essentially aims to pay tribute to all the workers and pioneers in the field of Cardiology in India, who in spite of limited resources ventured in an unchartered arena.

Summary Background As the epidemic of Zika virus expands in the Americas, countries across Africa and the Asia-Pacific region are becoming increasingly susceptible to the importation and possible local spread of the virus. To support public health readiness, we aim to identify regions and times where the potential health, economic, and social effects from Zika virus are greatest, focusing on resource-limited countries in Africa and the Asia-Pacific region. Methods Our model combined transportation network analysis, ecological modelling of mosquito occurrences, and vector competence for flavivirus transmission, using data from the International Air Transport Association, entomological observations from Zika’s primary vector species, and climate conditions using WorldClim. We overlaid monthly flows of airline travellers arriving to Africa and the Asia-Pacific region from areas of the Americas suitable for year-round transmission of Zika virus with monthly maps of climatic suitability for mosquito-borne transmission of Zika virus within Africa and the Asia-Pacific region. Findings An estimated 2·6 billion people live in areas of Africa and the Asia-Pacific region where the presence of competent mosquito vectors and suitable climatic conditions could support local transmission of Zika virus. Countries with large volumes of travellers arriving from Zika affected areas of the Americas and large populations at risk of mosquito-borne Zika virus infection include, India (67 422 travellers arriving per year; 1·2 billion residents in potential Zika transmission areas), China (238 415 travellers; 242 million residents), Indonesia (13 865 travellers; 197 million residents), Philippines (35 635 travellers; 70 million residents), and Thailand (29 241 travellers; 59 million residents). Interpretation Many countries across Africa and the Asia-Pacific region are vulnerable to Zika virus. Strategic use of available health and human resources is essential to prevent or mitigate

With the growing energy demands in India and its neighboring countries, Iran-Pakistan-India (IPI) gas pipeline assumes special significance. Energy-deficient countries such as India, China, and Pakistan are vying to acquire gas fields in different parts of the world. This has led to two conspicuous developments: first, they are competing against each other and secondly, a situation is emerging where they might have to confront the US and the western countries in the near future in their attempt to control energy bases. The proposed IPI pipeline is an attempt to acquire such base. However, Pakistan is playing its own game to maximize its leverages. Pakistan, which refuses to establish even normal trading ties with India, craves to earn hundreds of millions of dollars in transit fees and other annual royalties from a gas pipeline which runs from Iran's South Pars fields to Barmer in western India. Pakistan promises to subsidize its gas imports from Iran and thus also become a major forex earner. It is willing to give pipeline related 'international guarantees' notwithstanding its record of covert actions in breach of international law (such as the export of terrorism) and its reluctance to reciprocally provide India what World Trade Organization (WTO) rules obligate it to do-Most Favored Nation (MFN) status. India is looking at the possibility of using some set of norms for securing gas supply through pipeline as the European Union has already initiated a discussion on the issue. The key point that is relevant to India's plan to build a pipeline to source gas from Iran relates to national treatment for pipeline. Under the principle of national treatment which also figures in relation to foreign direct investment (FDI), the country through which a pipeline transits should provide some level of security to the transiting pipeline as it would have provided to its domestic pipelines. This paper will endeavor to analyze, first, the significance of this pipeline for India

Bhasin, A.

1995-01-01

The way a small company the size of Niko Resources Ltd. was able to enter the Indian oil patch was described. India was chosen because it presented many indicators of success, including an overall economic growth of 5.3 % in 1994, foreign currency reserves standing at over US $20 billion, exports increase of 20 %, and the introduction of a dramatic program of economic, industrial and trade liberalization. According to most estimates, India's energy demand is likely to increase significantly, and the energy sector will need over US $18 billion worth of expansion by the year 2000. Niko was the first Canadian company to enter the oil and gas exploration and development sector in India, but the competition is becoming fierce. There are two rounds of bidding for exploration each year, and foreign companies are welcome to participate in the existing joint ventures

Full Text Available Background: Importance of nutrition in human immunodeficiency virus (HIV is well-established; however, the information regarding the diet quality of people living with HIV (PLHIV especially in India is lacking. Objectives: The objective of this study is to assess the anthropometric and nutritional profile of Indian PLHIV. Material and Methods: The study was performed on 400 adult PLHIV registered at the Antiretroviral Center (ART center in New Delhi, India. Anthropometric data including height, weight, waist, hip, mid arm, and calf circumferences, were collected; 1-day 24-h dietary recall was done to gather nutrient intake from which nutrient adequacy ratios were computed. Mini Nutritional Assessment (MNA was also conducted. Results: The mean body mass index (BMI of the sample was 19.73 ± 3.55 kg/m 2 with around 40% having BMI <18.5 kg/m 2 . All anthropometric measurements were found to correlate positively and significantly with CD4 count (P < 0.05. The sample consumed poor quality of diet as they could not meet even the 2/3 rd of the Indian Council of Medical Research (2010 requirements for energy, protein, calcium, iron, riboflavin, niacin, folic acid, B12, copper, and zinc. Classification of subjects according to MNA indicated that more than 50% of the sample was at-risk of malnutrition and 34% were malnourished. With 40% of sample having BMI less than normal, 50% at risk of malnutrition together with poor nutrient intakes over a long period of time could contribute to further worsening of the nutritional status. Conclusion: There is a need to develop a database on nutritional profile of PLHIV in India which reinforces the need for development of effective strategies to improve their nutritional status.

The role of social-distancing measures, such as school closures, is a controversial aspect of pandemic mitigation planning. However, the timing of 2009 pandemic provides a natural experiment for evaluating the impact of school closure during holidays on influenza transmission. To quantify the transmission intensity of the influenza A (H1N1) pdm'09 in India, by estimating the time varying reproduction number (Rt) and correlating the temporal changes in the estimates of Rt for different regions of India with the timing of school holidays. We used daily lab-confirmed case reports of influenza A (H1N1) pdm'09 in India (during 17 May'09 to 17 May'10), stratified by regions. We estimated the transmissibility of the pandemic for different regions from these time-series, using Bayesian methods applied to a branching process model of disease spread and correlated the resulting estimates with the timing of school holidays in each region. The North-west region experienced two notable waves, with the peak of the first wave coinciding with the start of a 4 week school holiday (September-October'09). In the southern region the two waves were less clear cut, though again the first peak of the first wave coincided with the start of school holidays--albeit of less than 2 weeks duration (August'09). Our analysis suggests that the school holidays had a significant influence on the epidemiology of the 2009 pandemic in India. We estimate that school holidays reduced the reproduction number by 14-27% in different regions of India, relative to levels seen outside holiday periods. The estimates of the reproduction number obtained (with peak R values below 1.5) are compatible with those reported from other regions of the world. This work reinforces past studies showing the significant impact of school holidays on spread of 2009 pandemic virus, and by inference the role of contact patterns in children on transmission.

Full Text Available Strengthening the influence of India in the Asian region and in the world requires for resorting of the modernization experience of this country, including the development of its energy sector. India today is among the top ten countries to generate electricity per capita. At the same time, both traditional sources of energy production coexist in India (using the muscular strength of man and animals with the conditions for the development of modern energy infrastructure through foreign investments. The article attempts to trace the main stages of the formation and development of energy industry in India; the modern state of energy is analyzed and plans for its development are considered. The research is based on a complex of traditional methods and approaches based on the principle of scientific objectivity and systemic method used in research in the framework of international relations and political science. For more than a century of history of the development of energy sector in India significant success has been achieved. Starting with the electrification of large cities and industrial enterprises due to foreign investments in the colonial period, India, after gaining the independence, set the task of developing its own infrastructure, electrifying the countryside and providing the industry with energy resources. The greatest progress in the development of electric power and nuclear energy was made. Indian economic growth will increase India’s energy needs and quadruple the demand for electricity over the next 25 years. For this, India needs to solve the problems of energy efficiency, energy complex management, lack of standards and energy imports, as well as actively introduce alternative energy sources and move to clean electricity (increased use of water resources and solar energy, which can be done through the development of Russian -Indian cooperation.

CDM potential of bagasse cogeneration in India

Purohit, Pallav; Michaelowa, Axel

2007-01-01

So far, the cumulative capacity of renewable energy systems such as bagasse cogeneration in India is far below their theoretical potential despite government subsidy programmes. One of the major barriers is the high investment cost of these systems. The Clean Development Mechanism (CDM) provides industrialized countries with an incentive to invest in emission reduction projects in developing countries to achieve a reduction in CO 2 emissions at lowest cost that also promotes sustainable development in the host country. Bagasse cogeneration projects could be of interest under the CDM because they directly displace greenhouse gas emissions while contributing to sustainable rural development. This study assesses the maximum theoretical as well as the realistically achievable CDM potential of bagasse cogeneration in India. Our estimates indicate that there is a vast theoretical potential of CO 2 mitigation by the use of bagasse for power generation through cogeneration process in India. The preliminary results indicate that the annual gross potential availability of bagasse in India is more than 67 million tonnes (MT). The potential of electricity generation through bagasse cogeneration in India is estimated to be around 34 TWh i.e. about 5575 MW in terms of the plant capacity. The annual CER potential of bagasse cogeneration in India could theoretically reach 28 MT. Under more realistic assumptions about diffusion of bagasse cogeneration based on past experiences with the government-run programmes, annual CER volumes by 2012 could reach 20-26 million. The projections based on the past diffusion trend indicate that in India, even with highly favorable assumptions, the dissemination of bagasse cogeneration for power generation is not likely to reach its maximum estimated potential in another 20 years. CDM could help to achieve the maximum utilization potential more rapidly as compared to the current diffusion trend if supportive policies are introduced

An Overview of Uranium Exploration Strategy in India

Chaki, A., E-mail: director.amd@gov.in [Atomic Minerals Directorate for Exploration and Research, Hyderabad (India)

2014-05-15

Uranium exploration in India dates back from 1949 and the first mineralized area was located in the early 1950s in Singhbhum Shear Zone (SSZ), eastern India. Since then, a number of potential and promising uranium provinces have been established in India. The potential uranium provinces include SSZ, Dongargarh, Aravalli, Siwalik belt, Mahadek basin, south-western and northern parts of Cuddapah basin, North Delhi Fold Belt, Bhima and Kaladgi basins. The promising uranium provinces are Proterozoic Chhattisgarh, Indravati, Gwalior, Vindhyan, Shillong basins, Gondwana basins of Central India and semi-arid regions of western Rajasthan. With the establishment of large tonnage-high grade Lower-middle Proterozoic unconformity deposits in Canada and Australia, there was a paradigm shift in the exploration strategy towards the Proterozoic basins of India. The discovery of unconformity related uranium mineralisation in the northern part of Proterozoic Cuddapah basin in southern India in 1991 and discovery of few deposits in the province has opened the avenues for finding of similar deposits in Cuddapah and other 13 Proterozoic basins in India. As a sequel, Proterozoic Bhima basin in southern India has been recognized as a potential target for uranium mineralization, where a low tonnage medium grade deposit has been established and mine development works are in progress. Sustained exploration efforts in other Proterozoic basins have yielded success in a few basins such as Deshnur area in Kaladgi Basin of southern India. Considerable uranium resources have been established in Proterozoic Cuddapah and Bhima basins. Apart from northern parts of Cuddapah and Bhima basins, areas in the southwestern part of Cuddapah basin for stratabound type, where a mine is under construction; Proterozoic Kaladgi basin for vein type; Cretaceous Mahadek basin for sandstone type and the North Delhi Fold belt for vein type of mineralization have been prioritized as potential areas for exploration

Full Text Available Iodine deficiency disorders (IDD constitute the single largest cause of preventable brain damage worldwide. Majority of consequences of IDD are invisible and irreversible but at the same time these are preventable. In India, the entire population is prone to IDD due to deficiency of iodine in the soil of the subcontinent and consequently the food derived from it. To combat the risk of IDD, salt is fortified with iodine. However, an estimated 350 million people do not consume adequately iodized salt and, therefore, are at risk for IDD. Of the 325 districts surveyed in India so far, 263 are IDD-endemic. The current household level iodized salt coverage in India is 91 per cent with 71 per cent households consuming adequately iodized salt. The IDD control goal in India was to reduce the prevalence of IDD below 10 per cent in the entire country by 2012. What is required is a "mission approach" with greater coordination amongst all stakeholders of IDD control efforts in India. Mainstreaming of IDD control in policy making, devising State specific action plans to control IDD, strict implementation of Food Safety and Standards (FSS Act, 2006, addressing inequities in iodized salt coverage (rural-urban, socio-economic, providing iodized salt in Public Distribution System, strengthening monitoring and evaluation of IDD programme and ensuring sustainability of IDD control activities are essential to achieve sustainable elimination of IDD in India.

Full Text Available Medical tourism is a fast growing multibillion-dollar industry around the world and it entails trade in services of two major industries i.e. medicine and tourism. India is currently promoting medical tourism aggressively. The present study presents an overview of medical tourism in India and presents a SWOT analysis and concludes with some valuable suggestions to develop India as a global Medical Tourism destination. The research is descriptive in nature and the data used includes interviews and discussions with various stakeholders as well as a literature review based on secondary sources. The research reveals that the key competitive advantages of India in the medical tourism arena arises from the following: low cost advantage, strong reputation in the advanced healthcare segment (cardiovascular surgery, organ transplants, eye surgery etc. and the diversity of the many and unique tourist destinations available in the country. The key concerns facing the industry include: absence of government initiatives, the lack of a coordinated effort to promote the industry, the lack of an accreditation mechanism for hospitals and the lack of uniform pricing policies and standards across hospitals throughout India.

Climate change and groundwater: India's opportunities for mitigation and adaptation

International Nuclear Information System (INIS)

Shah, Tushaar

2009-01-01

For millennia, India used surface storage and gravity flow to water crops. During the last 40 years, however, India has witnessed a decline in gravity-flow irrigation and the rise of a booming 'water-scavenging' irrigation economy through millions of small, private tubewells. For India, groundwater has become at once critical and threatened. Climate change will act as a force multiplier; it will enhance groundwater's criticality for drought-proofing agriculture and simultaneously multiply the threat to the resource. Groundwater pumping with electricity and diesel also accounts for an estimated 16-25 million mt of carbon emissions, 4-6% of India's total. From a climate change point of view, India's groundwater hotspots are western and peninsular India. These are critical for climate change mitigation as well as adaptation. To achieve both, India needs to make a transition from surface storage to 'managed aquifer storage' as the center pin of its water strategy with proactive demand- and supply-side management components. In doing this, India needs to learn intelligently from the experience of countries like Australia and the United States that have long experience in managed aquifer recharge.

Cardiovascular research in India: a perspective.

2011-03-01

With cardiovascular disease (CVD) emerging as a major cause of mortality in India, clinical research in CVD is becoming increasingly important. There are several favorable factors that offer robust growth of clinical research infrastructure in India: well-established system of governance, a large investment in medical education infrastructure, growing interest in building capacity in clinical research, the presence of regulatory mechanisms governing clinical research, a large pharmaceutical industry, and a highly developed information technology and data processing infrastructure. However, the lack of trained research manpower, inadequate public spending on health, uneven distribution of health infrastructure, and the large prevalence of pretransitional diseases are major weakness in undertaking high-quality clinical research in CVD. Analysis of the contemporary scenario reveals that there are 3 important opportunities for clinical research in India: the need to identify low cost but cutting edge and context-specific interventions to address the health needs of India's large population, the potential for high-quality research, and the high degree of interest (domestically and internationally) in investing in clinical research education and infrastructure.

India and the nuclear safeguards controversy

International Nuclear Information System (INIS)

Poulose, T.T.

1979-01-01

A brief account of the origin and development of the safeguards system to prevent diversion of nuclear material from its peaceful uses to production of nuclear explosives is given. India is firmly opposed to the discriminatory characteristics of the system. The IAEA safeguards apply to those nations (most of them developing nations) seeking Agency aid and not to the nuclear weapons powers and other advanced nuclear powers who do not need Agency aid. Even though the Tarapur Agreement does not provide for full scope safeguards, U.S.A., particularly after 1974 Pokharan explosion, is pressurisinq India to accept them by delaying the supply of enriched uranium for the Tarapur Power Plant. As is assumed by the Americans, India is not indifferent to the problem of proliferation. On the other hand, it has renounced nuclear weapons as an instrument of national policy and is committed to non-proliferation. India has all along since independence advocated universal and non-discriminating full scope safeguards system applicable to all nations, both nuclear and non-nuclear powers and to all nuclear facilities.

Full Text Available Abstract Background Dengue is emerging as a major public health concern in many parts of the world. The development of a one-step, single tube, rapid, and multiplex reverse transcription polymerase chain reaction (M-RT-PCR for simultaneous detection and typing of dengue virus using serotype specific primers during acute phase of illness is reported. Results An optimal assay condition with zero background was established having no cross-reaction with closely related members of flavivirus (Japanese encephalitis, West Nile, Yellow fever and alphavirus (Chikungunya. The feasibility of M-RT-PCR assay for clinical diagnosis was validated with 620 acute phase dengue patient sera samples of recent epidemics in India. The comparative evaluation vis a vis conventional virus isolation revealed higher sensitivity. None of the forty healthy serum samples screened in the present study revealed any amplification, thereby establishing specificity of the reported assay for dengue virus only. Conclusion These findings clearly suggested that M-RT-PCR assay reported in the present study is the rapid and cost-effective method for simultaneous detection as well as typing of the dengue virus in acute phase patient serum samples. Thus, the M-RT-PCR assay developed in this study will serve as a very useful tool for rapid diagnosis and typing of dengue infections in endemic areas.

A new, reliable and secure virus assay method, named the competitive virus assay (CVA) method, has been established for the titration of bovine viral diarrhea viruses (BVDVs) that either show the exaltation of Newcastle disease virus (END) phenomenon or heterologous interference phenomenon (but not the END phenomenon). This method is based on the principle of (1) homologous interference between BVDVs, by using BVDV RK13/E(-) or BVDV RK13/E(+) strains as competitor virus, and (2) END phenomenon and heterologous interference, by using attenuated Newcastle disease virus (NDV) TCND strain as challenge virus. In titration of BVDV END(+) and BVDV END(-) viruses, no significant difference in estimated virus titer was observed between CVA and conventional methods. CVA method demonstrated comparable levels of sensitivity and accuracy as conventional END and interference methods, which require the use of a velogenic Miyadera strain of NDV and vesicular stomatitis virus (VSV), both of which are agents of high-risk diseases. As such, the CVA method is a safer alternative, with increased bio-safety and bio-containment, through avoidance of virulent strains that are commonly employed with conventional methods.

White Spot Syndrome Virus (WSSV) is a dsDNA virus causing White Spot Syndrome Disease (WSSD) in shrimp with almost 100% morality rate within 3-10 days. In Bangladesh, WSSD is one of the major impediments of shrimp farming. This study first investigated the prevalence and distribution of WSSV in cultured shrimps of the coastal regions in Bangladesh. A total of 60 shrimp samples, collected from the 25 shrimp farms of different coastal regions (Satkhira, Khulna, Bagerhat and Cox's Bazar), were analysed during 2013-2014 by conventional PCR using VP28 and VP664 gene-specific primers; 39 of 60 samples were found WSSV positive. SYBR green real-time PCR using 71-bp amplicon for VP664 gene correlated well with conventional PCR data. The prevalence rates of WSSV among the collected 60 samples were Satkhira 79%, Khulna 50%, Bagerhat 38% and Cox's Bazar 25%. Sequencing of WSSV-positive PCR amplicons of VP28 showed 99% similarity with WSSV NCBI Ref/Seq Sequences. Molecular analysis of the VP28 gene sequences of WSSV revealed that Bangladeshi strains phylogenetically affiliated to the strains belong to India. This work concluded that WSSV infections are widely distributed in the coastal regions cultured shrimp in Bangladesh. © 2014 The Society for Applied Microbiology.

Urology in ancient India

Directory of Open Access Journals (Sweden)

Sakti Das

2007-01-01

Full Text Available The practice of medical and surgical measures in the management of urological ailments prevailed in ancient India from the Vedic era around 3000 BC. Subsequently in the Samhita period, the two stalwarts - Charaka in medicine and Susruta in surgery elevated the art of medicine in India to unprecedented heights. Their elaboration of the etiopathological hypothesis and the medical and surgical treatments of various urological disorders of unparalleled ingenuity still remain valid to some extent in our contemporary understanding. The new generation of accomplished Indian urologists should humbly venerate the legacy of the illustrious pioneers in urology of our motherland.

As the epidemic of Zika virus expands in the Americas, countries across Africa and the Asia-Pacific region are becoming increasingly susceptible to the importation and possible local spread of the virus. To support public health readiness, we aim to identify regions and times where the potential health, economic, and social effects from Zika virus are greatest, focusing on resource-limited countries in Africa and the Asia-Pacific region. Our model combined transportation network analysis, ecological modelling of mosquito occurrences, and vector competence for flavivirus transmission, using data from the International Air Transport Association, entomological observations from Zika's primary vector species, and climate conditions using WorldClim. We overlaid monthly flows of airline travellers arriving to Africa and the Asia-Pacific region from areas of the Americas suitable for year-round transmission of Zika virus with monthly maps of climatic suitability for mosquito-borne transmission of Zika virus within Africa and the Asia-Pacific region. An estimated 2·6 billion people live in areas of Africa and the Asia-Pacific region where the presence of competent mosquito vectors and suitable climatic conditions could support local transmission of Zika virus. Countries with large volumes of travellers arriving from Zika virus-affected areas of the Americas and large populations at risk of mosquito-borne Zika virus infection include India (67 422 travellers arriving per year; 1·2 billion residents in potential Zika transmission areas), China (238 415 travellers; 242 million residents), Indonesia (13 865 travellers; 197 million residents), Philippines (35 635 travellers; 70 million residents), and Thailand (29 241 travellers; 59 million residents). Many countries across Africa and the Asia-Pacific region are vulnerable to Zika virus. Strategic use of available health and human resources is essential to prevent or mitigate the health, economic, and social

2014-01-01

The diseases originating from animals or associated with man and animals are remerging and have resulted in considerable morbidity and mortality. The present review highlights the re-emergence of emerging mainly zoonotic diseases like chikungunya, scrub typhus, and extension of spatial distribution of cutaneous leishmaniasis from western Rajasthan to Himachal Pradesh, Kerala, and Haryana states; West Nile virus to Assam, and non-endemic areas of Japanese encephalitis (JE) like Maharashtra and JE to Delhi; Crimean-Congo hemorrhagic fever making inroads in Ahmedabad; and reporting fifth parasite of human malaria with possibility of zoonosis have been highlighted, which necessitates further studies for prevention and control. Emphasis has been given on understanding the ecology of reservoir hosts of pathogen, micro niche of vector species, climatic, socioeconomic risk factors, etc. Development of facilities for diagnosis of virus from insects, reservoirs, and human beings (like BSL4, which has been established in NIV, Pune), awareness about symptoms of new emerging viral and other zoonotic diseases, differential diagnosis, risk factors (climatic, ecological, and socioeconomic) and mapping of disease-specific vulnerable areas, and mathematical modeling for projecting epidemiological scenario is needed for preparedness of public health institutes. It is high time to understand the ecological link of zoonotic or anthroponotic diseases for updated risk maps and epidemiological knowledge for effective preventive and control measures. The public health stakeholders in India as well as in Southeast Asia should emphasize on understanding the eco-epidemiology of the discussed zoonotic diseases for taking preventive actions.

Population in 1995 was about 1.2 billion in China and about 935 million in India. Populations are expected to reach respectively 1.5 billion and 1.4 billion by 2025. These two countries now and in the future will average about 35% of total world population. This article compares the current and expected demographic, economic, and environmental conditions in China and India. How these countries manage their growth, poverty, and population will affect the region and the world as well as each nation. China's fertility is now below replacement but population momentum will increase population by about 300 million/year. India's fertility is 3.6 children/woman and India will add 450 million/year. China's population over 60 years old will reach 20% by 2020, while India's will be under 15% in 2025. China will be almost 55% urban by 2025 from 30% in the 1990s, and India will be 45% urban from 27% urban. China's economic growth has averaged over 9%/year compared to India's 5% annual growth during the 1980s and the economic decline during the 1990s. China has 12% of rural population living below the poverty line and India has about 33% of its total population impoverished. China's life expectancy is about 10 years higher. Under-five mortality is 43/1000 live births in China and 131/1000 in India. Poverty-related diseases are still high in India. China is a homogenous population with an authoritarian regime. India is a democracy with a large nongovernmental community and a heterogenous population. India has about 33% of the land area of China but over twice the agricultural land per person. About 50% of China's land and only 25% of India's land is irrigated. Water resources are problems in northern China and much of India. Air and water pollution are problems in both countries. Differences in the population-environment-development context are discussed in terms of the effects of poverty, the constraints posed by development, and the environmental impact of rising per capita

Vaccine delivery system for tuberculosis based on nano-sized hepatitis B virus core protein particles

Full Text Available Dhananjayan Dhanasooraj, R Ajay Kumar, Sathish MundayoorMycobacterium Research Group, Rajiv Gandhi Centre for Biotechnology, Kerala, IndiaAbstract: Nano-sized hepatitis B virus core virus-like particles (HBc-VLP are suitable for uptake by antigen-presenting cells. Mycobacterium tuberculosis antigen culture filtrate protein 10 (CFP-10 is an important vaccine candidate against tuberculosis. The purified antigen shows low immune response without adjuvant and tends to have low protective efficacy. The present study is based on the assumption that expression of these proteins on HBc nanoparticles would provide higher protection when compared to the native antigen alone. The cfp-10 gene was expressed as a fusion on the major immunodominant region of HBc-VLP, and the immune response in Balb/c mice was studied and compared to pure proteins, a mixture of antigens, and fusion protein-VLP, all without using any adjuvant. The humoral, cytokine, and splenocyte cell proliferation responses suggested that the HBc-VLP bearing CFP-10 generated an antigen-specific immune response in a Th1-dependent manner. By virtue of its self-adjuvant nature and ability to form nano-sized particles, HBc-VLPs are an excellent vaccine delivery system for use with subunit protein antigens identified in the course of recent vaccine research.Keywords: Mycobacterium tuberculosis, VLP, hepatitis B virus core particle, CFP-10, self-adjuvant, vaccine delivery

Virus wars: using one virus to block the spread of another

Directory of Open Access Journals (Sweden)

Matthew L. Paff

2016-06-01

Full Text Available The failure of traditional interventions to block and cure HIV infections has led to novel proposals that involve treating infections with therapeutic viruses–infectious viruses that specifically inhibit HIV propagation in the host. Early efforts in evaluating these proposals have been limited chiefly to mathematical models of dynamics, for lack of suitable empirical systems. Here we propose, develop and analyze an empirical system of a therapeutic virus that protects a host cell population against a lethal virus. The empirical system uses E. coli bacteria as the host cell population, an RNA phage as the lethal virus and a filamentous phage as the therapeutic virus. Basic dynamic properties are established for each virus alone and then together. Observed dynamics broadly agree with those predicted by a computer simulation model, although some differences are noted. Two cases of dynamics are contrasted, differing in whether the therapeutic virus is introduced before the lethal virus or after the lethal virus. The therapeutic virus increases in both cases but by different mechanisms. With the therapeutic virus introduced first, it spreads infectiously without any appreciable change in host dynamics. With the therapeutic virus introduced second, host abundance is depressed at the time therapy is applied; following an initial period of therapeutic virus spread by infection, the subsequent rise of protection is through reproduction by hosts already protected. This latter outcome is due to inheritance of the therapeutic virus state when the protected cell divides. Overall, the work establishes the feasibility and robustness to details of a viral interference using a therapeutic virus.

Zika virus disease

Directory of Open Access Journals (Sweden)

Adel I Al-Afaleq

2017-01-01

Full Text Available The Zika virus is an arbovirus belonging to the virus family Flaviviridae. The virus was isolated in 1947 from a rhesus monkey in the Zika Forest of Uganda. The virus causes sporadic mild human infections in Africa and later in Asia. However, by 2007 a major shift in its infection pattern was noticed and thousands of human infections were reported in the State of Yap and Federated States of Micronesia. In the last 3 years, major outbreaks have continued to occur and the virus has spread to several Pacific and American countries. These outbreaks were mostly asymptomatic; however, there were more severe clinical signs associated with the infections. Those signs included microcephaly and Guillain–Barre syndrome. It is believed that various species of mosquitoes can biologically transmit the virus. However, Aedes aegypti is most widely associated with the Zika virus. Recently, new modes of virus transmission have been reported, including mother-to-fetus, sexual, blood transfusion, animal bites, laboratory exposure and breast milk. Differential diagnosis is very important as some other arboviruses such as yellow fever virus, West Nile virus, dengue virus, and chikungunya virus have similar clinical manifestations to the Zika virus infection as well as relating serologically to some of these viruses. Established laboratory diagnostic tests to detect the Zika virus are limited, with reverse transcription polymerase chain reaction being the most widely used test. Taking into consideration the quickness of the spread of infection, size of the infected population and change of the infection severity pattern, the Zika virus infection merits collective efforts on all levels to prevent and control the disease. Limited research work and data, concurrent infection with other arboviruses, involvement of biological vectors, mass crowd events, human and trade movements and lack of vaccines are some of the challenges that we face in our efforts to prevent and

2013-01-01

Around 41% of Human Immunodeficiency Virus (HIV) cases in Nepal occur in seasonal migrant laborers. Dalit migrant laborers represent the largest proportion of reported HIV cases in the Far Western Region (Sudur Pashchimanchal, or Far West), Nepal. The study's objectives were to assess sexual behavior, condom use status and HIV risk perception among Dalit migrant laborers to India from Far West Region, Nepal. The study was conducted among Dalit male migrant laborers aged 15 years and above who had migrated for at least six months of the last two years to India. For the sampling the village development committees (VDCs) from Achham, Doti and Kanchanpur districts of Nepal were purposively selected. The data were collected in March and April 2011 via ten in-depth interviews and four focus group discussions and analyzed using content analysis. Poor socio-economic status, caste-related discrimination, and lack of employment opportunities push large groups of young Dalits to migrate to India for employment, where they engage in sex with female sex workers (FSWs). The participants described unmarried status, peer influence, alcohol use, low-priced sex with FSWs and unwillingness to use condoms as common factors of their migration experience. Lack of awareness on HIV/AIDS was common among study participants. Awareness of HIV/AIDS and faithful, monogamous partnerships are reported as factors influencing safer sexual behavior. Dalits are an especially vulnerable population among migrant laborers and may be over-represented in new HIV infections in Nepal. Comprehensive surveying and health promotion programs targeted to this population are urgently needed and potent methods of stopping HIV spread.

Gender disparity in late-life cognitive functioning in India: findings from the longitudinal aging study in India.

To examine gender disparities in cognitive functioning in India and the extent to which education explains this disparity in later life. This study uses baseline interviews of a prospective cohort study of 1,451 community-residing adults 45 years of age or older in four geographically diverse states of India (Karnataka, Kerala, Punjab, Rajasthan). Data collected during home visits includes cognitive performance tests, and rich sociodemographic, health, and psychosocial variables. The cognitive performance tests include episodic memory, numeracy, and a modified version of the Mini-Mental State Examination. We find gender disparity in cognitive function in India, and this disparity is greater in the north than the south. We also find that gender disparities in educational attainment, health, and social and economic activity explain the female cognitive disadvantage in later life. We report significant gender disparities in cognitive functioning among older Indian adults, which differ from gender disparities in cognition encountered in developed countries. Our models controlling for education, health status, and social and economic activity explain the disparity in southern India but not the region-specific disparity in the northern India. North Indian women may face additional sources of stress associated with discrimination against women that contribute to persistent disadvantages in cognitive functioning at older ages. © The Author 2014.

This article examines the feasibility and advisability of India joining the Non-Proliferation Treaty (NPT). It demonstrates that (a) the non-proliferation regime, which is larger and more varied than the NPT, has received significant cooperation from India in the past; (b) that in order to effectively deal with further challenges from nuclear renaissance, nuclear deterrence, and terrorism, the regime will need to craft creative, non-NPT centric solutions like the US-India nuclear agreement, to co-opt India; and (c) that India's interest will be better served by trying to shape the regime from within rather than remaining a reasoned voice from without.

2015-01-01

History as a science revolves around memories, travellers' tales, fables and chroniclers' stories, gossip and trans-telephonic conversations. Medicine itself as per the puritan's definition is a non-exact science because of the probability-predictability-sensitivity-specificity factors. Howsoever, the chronicles of Cardiology in India is quite interesting and intriguing. Heart and circulation was known to humankind from pre-Vedic era. Various therapeutics measures including the role of Yoga and transcendental meditation in curing cardiovascular diseases were known in India. Only recently there has been resurgence of the same globally. There have been very few innovations in Cardiology in India. The cause of this paucity possibly lie in the limited resources. This has a vicious effect on the research mentality of the population who are busy in meeting their daily requirements. This socio-scientific aspect needs a thorough study and is beyond the scope of the present documentation. Present is the future of past and so one must not forget the history which is essentially past that give the present generation the necessary fulcrum to stand in good stead. The present article essentially aims to pay tribute to all the workers and pioneers in the field of Cardiology in India, who in spite of limited resources ventured in an unchartered arena.

Full Text Available La política exterior de la India desde su independencia el 15 agosto de 1947, ha sido de cooperación y conciliación, y no de confrontación. Ésta podría haber sido ampliada cuando los infiltrados pakistaníes entraron en el territorio de la India en 1948, ya que el entonces Primer Ministro instó a que este asunto se remitiera al recién formado Consejo Mundial de Naciones Unidas. Si se recorre la historia, encontraríamos que las tres guerras entre India y Pakistán fueron iniciadas por Pakistán ante lo cual la India tuvo que defender su territorio. Similar situación surgió cuando China rompió unilateralmente el acuerdo de Pancha Sheel, invadiendo el territorio de la India. Este artículo hace un modesto intento de trazar la política de la India hacia el cercano oriente o hacia las naciones del sureste. Describe los vínculos históricos y culturales entre la India y las naciones del sur de Asia oriental y la consolidación definitiva de la “política hacia el oriente de la India”. En este artículo se toman en consideración los intereses económicos y estratégicos de la región y se espera que pudiera permitir a los lectores entender la política de la India hacia las naciones del sudeste de Asia.
