    H5N1 avian influenza viruses (AIVs) have spread widely to more than 60 countries spanning three continents. To control the disease, vaccination of poultry is implemented in many of the affected countries, especially in those where H5N1 viruses have become enzootic in poultry and wild birds. Recently, considerable progress has been made toward the development of novel avian influenza (AI) vaccines, especially recombinant virus vector vaccines and DNA vaccines. Here, we will discuss the recent advances in vaccine development and use against H5N1 AIV in poultry. Understanding the properties of the available, novel vaccines will allow for the establishment of rational vaccination protocols, which in turn will help the effective control and prevention of H5N1 AI.

RESULTS: We show Z chromosomes in general have a significantly higher substitution rate in introns and synonymous...... protein-coding sites than autosomes, driven by the male-to-female mutation bias ('male-driven evolution' effect). Our genome-wide estimate reveals that the degree of such a bias ranges from 1.6 to 3.8 among different species. G + C content of third codon positions exhibits the same trend of gradual......

    Why has the French food safety agency been particularly mobilized on zoonoses like bovine spongiform encephalopathy ("mad cow disease") or highly pathogenic avian influenza ("bird flu") ? Because sanitary crisis make explicit an ambivalent relationship between humans and animals (animals being perceived alternatively as providers of goods and as bearers of threats), and to the circulation of life in general (the contaminated blood crises being due to the rapprochement of blood giving and blood receiving). The sociology of risks needs therefore to reintegrate the idea of an intention of the risk bearer (risk with enemy), and the sociology of alimentation needs to reintegrate the analysis of the conditions of production. Mad cow disease is the paradigmatic food safety crisis because it brings together the poles of production and consumption, of animals and humans. It therefore belongs to anthropology. PMID:18198116

  10. Current status, surveillance and control of avian flu in domestic and wild bird populations in Bulgaria

    International Nuclear Information System (INIS)

    Avian influenza (AI) is a highly contagious viral disease affecting several species of food producing birds (chickens, turkeys, quails, guinea fowl, etc.), as well as pet birds and wild birds. The AI viruses are divided in two groups based on their ability to cause disease (pathogenicity). Highly pathogenic avian influenza (HPAI) virus spreads rapidly, may cause serious disease and result in high mortality rates (up to 100% within 48 hours). The low pathogenic avian influenza (LPAI) can causes mild disease that may be undetected or no symptoms at all in some species of birds. Since 1997 millions of chicken have been reported to have died due to HPAI H5N1 in countries of South-East Asia. In 2003 AI virus H7N7 affected poultry farms in Netherlands, then penetrated to Belgium and Germany. It had been considered that among human community there were circulating A viruses of 3 subtypes of H type (H1, H2 and H3) and 2 subtypes of N type (N1 and N2). However, for the recent years it has established that AI viruses as a result of mutation have changed their biological features and acquired a capacity of overcoming an interspecies barrier and affecting humans, mostly with lethal outcome. Once domestic birds are infected, avian influenza outbreaks can be difficult to control and often cause major economic impacts for poultry farmers in affected countries, since mortality rates are high and infected fowl generally must be destroyed -- the technical term is 'culled' -- in order to prevent the spread of the disease. Anatidae (ducks, geese and swans) is a group of water birds that is ecologically dependent on wetlands for at least some aspects of their annual cycle. Anatidae species use a wide range of wetlands, from the high arctic tundra, rivers and estuaries, freshwater or saline lakes, and ponds or swamps to coastal lagoons and inter-tidal coastal areas such as mud-flats, bays and the open sea. They also utilize man-made wetlands such as rice fields and other agricultural

    2010-01-01

    Full Text Available In epidemiology or in epizootiology, there are some infectious diseases that have potential for significant reduction of the susceptible species population. Over the past few decades, epidemiologists were concentrated on diseases that were 'modern' and made front-page news in tabloids. One should recall diseases like bovine spongiform encephalopathy, SARS and AIDS syndromes. However, we should always be aware of the most dangerous diseases such as our old friend, influenza, or simply, flu. In the past decade, we heard about 'bird' or 'swine' influenza. It is the same disease for different animal species as well as for man. Influenza owes its characteristics to specific virus biology as well as to the epidemiology-epizootiology characteristics of the susceptible species. Antigenic changes that took place thanks to reassortment mechanisms of the viral gene segments cause the onset of the new antigenic combinations of the hemaglutinin and neuraminidase molecules. As a result, new H and/or N antigenic formulas appear for the first time in totally susceptible animal and human populations. That means that in such circumstances, no person in the world is immune to the virus. In that case, such a virus can cause a pandemic with disastrous consequences since influenza is a disease with significant mortality, especially in some segments of the human (as well as animal population. Birds and swine are virus reservoirs, but these species are at the same time live test tubes in which the virus resides, changes and adapts itself not only to the original species but to other species as well. That means that there is no 'bird' or 'swine' flu. Influenza is an infection of several important animal species as well as man that have potential not only for the reduction of the population size but, in case of the human population, for influencing social and economic life. .

    Science.gov (United States)

    Wright, Natalie A; Gregory, T Ryan; Witt, Christopher C

    2014-03-22

    The tendency for flying organisms to possess small genomes has been interpreted as evidence of natural selection acting on the physical size of the genome. Nonetheless, the flight-genome link and its mechanistic basis have yet to be well established by comparative studies within a volant clade. Is there a particular functional aspect of flight such as brisk metabolism, lift production or maneuverability that impinges on the physical genome? We measured genome sizes, wing dimensions and heart, flight muscle and body masses from a phylogenetically diverse set of bird species. In phylogenetically controlled analyses, we found that genome size was negatively correlated with relative flight muscle size and heart index (i.e. ratio of heart to body mass), but positively correlated with body mass and wing loading. The proportional masses of the flight muscles and heart were the most important parameters explaining variation in genome size in multivariate models. Hence, the metabolic intensity of powered flight appears to have driven genome size reduction in birds.

    Full Text Available Bird flu disease that attacks duck dismissed the notion of duck immune to bird flu disease. Learning from the experience of bird flu disease that attacks poultry in the year of 2004-2005, necessary to measure the spread of disease prevention bird flu in ducks. This paper aims to describe the business and trade patterns of duck associated with the spread of avian influenza and predict the socio-economic impact of bird flu on duck farms in Indonesia. Duck rearing patterns mostly are in the extensive and semi-intensive system, that have large potential disease transmission occured between duck and wild. Illegal trade in the crossborder region and imports from countries that re-export it, ias alo become potential as well as the entry point to the bird flu virus in Indonesia. Ducks trade between regions by land transportation is difficult to control as well becomes the potential media to spread of the virus to a wider area. The economic impact of bird flu on duck business occured due to the death of ducks, decline in production and loss of job opportunities, while that on demand reduction was not significant. Small scale farmers that were bankrupt as a result of bird flu outbreaks may require technical assistance and access to capital for recovery. In the future, development of ducks business should be directed at duck farms into a semi-intensive and intensive system to facilitate the control of epidemic diseases

    Influenza A viruses are hosted by numerous avian and mammalian species, which have shaped their evolution into distinct lineages worldwide. The viral genome consists of eight RNA segments that are frequently exchanged between different viruses via a process known as genetic reassortment. A complete genotype nomenclature is essential to describe gene segment reassortment. Specialized bioinformatic tools to analyze reassortment are not available, which hampers progress in understanding its role...

    The present article is aimed on comprehensive view of Swine flu. It was first isolated from pigs in 1930 in USA. Pandemic caused by H1N1 in 2009 brought it in limelight. Itís a viral respiratory disease caused by viruses that infects pigs, resulting in nasal secretions, barking cough, decreased appetite, and listless behavior. Swine virus consist of eight RNA strands, one strand derived from human flu strains, two from avian (bird) strains, and five from swine strains. Swine flu spreads from infected person to healthy person by inhalation or ingestion of droplets contaminated with virus while sneezing or coughing. Two antiviral agents have been reported to help prevent or reduce the effects of swine flu, flu shot and nasal spray. WHO recommended for pandemic period to prevent its future outbreaks through vaccines or non-vaccines means. Antiviral drugs effective against this virus are Tamiflu and Relenza. Rapid antigen testing (RIDT), DFA testing, viral culture, and molecular testing (RT-PCR) are used for its diagnosis in laboratory

    Full Text Available As a greater number and diversity of high-quality vertebrate reference genomes become available, it is increasingly feasible to use these references to guide new draft assemblies for related species. Reference-guided assembly approaches may substantially increase the contiguity and completeness of a new genome using only low levels of genome coverage that might otherwise be insufficient for de novo genome assembly. We used low-coverage (∼3.5-5.5x Illumina paired-end sequencing to assemble draft genomes of two bird species (the Gunnison Sage-Grouse, Centrocercus minimus, and the Clark's Nutcracker, Nucifraga columbiana. We used these data to estimate de novo genome assemblies and reference-guided assemblies, and compared the information content and completeness of these assemblies by comparing CEGMA gene set representation, repeat element content, simple sequence repeat content, and GC isochore structure among assemblies. Our results demonstrate that even lower-coverage genome sequencing projects are capable of producing informative and useful genomic resources, particularly through the use of reference-guided assemblies.

  5. Swine flu - A pandemic outbreak

    Directory of Open Access Journals (Sweden)

    Jini George

    Full Text Available Hippocrates had described influenza like outbreak in 412 B.C. and since then repeated influenza like epidemics and pandemics have been recorded in recent times. One of the greatest killers of all time was the pandemic of swine flu (Spanish flu of 1918-1919, when 230 million people died. Annual influenza epidemics are estimated to affect 5–15% of the global population, resulting in severe illness in 3–5 million patients causing 250,000–500,000 deaths worldwide. Severe illness and deaths occur mainly in the high-risk populations of infants, the elderly and chronically ill patients. The 2009 outbreak of swine flu is thought to be a mutation more specifically a reassortment of four known strains of influenza A virus subtype H1N1; one endemic in humans, one endemic in birds, and two endemic in pigs. WHO officially declared the outbreak to be a pandemic on June 11, 2009, but stressed that the new designation was a result of the global "spread of the virus," not its severity.

  6. SWINE FLU - A DESCRIPTIVE REVIEW

    Directory of Open Access Journals (Sweden)

    Nain Parminder

    2011-02-01

    Full Text Available Swine influenza, also called pig influenza, swine flu, hog flu and pig flu, is an infection by any one of several types of swine influenza virus. Swine influenza virus (SIV or S-OIV (swine-origin influenza virus is any strain of the influenza family of viruses that is endemic in pigs. In H1N1, the ‘H’ refers to the hemagglutinin protein, and the ‘N’ refers to the neuraminidase protein. While at present the virus is causing a mild disease, the next wave may be more severe. Influenza is a simple virus, with just eight genes, but it makes poor copies of itself, leading to constant mutation. Influenza viruses are by nature unstable and unpredictable and have the unique capability of changing their antigenic characteristics by mutation. Occasionally, novel strains also emerge, often through re-assortment or exchange of genetic material among influenza viruses from different animal, human or bird sources. Such genetic restructuring occurs regularly in nature and, at times, provides the virus with the capability of causing widespread disease in immunologically naïve populations.

  8. Phylogenetic Analysis of the Neuraminidase Gene Reveals that the H5N1 Strains Prevalent in Chickens During 2006 Bird Flu Outbreaks in Two Regions of Maharashtra, India Are Genetically Different

    Institute of Scientific and Technical Information of China (English)

    Mohd Danishuddin; Asad U. Khan

    2009-01-01

    In February 2006, two outbreaks of highly pathogenic avian influenza A virus subtype H5N1 occurred in chickens in two neighboring districts (first in Nandurbar and second in Jaigaon) of Maharashtra, India, in a span of 12 days. In the present study, the neuraminidase (NA) gene of the two Indian H5N1 isolates was taken into consideration to find if the two strains are genetically similar. Phylogenetic analysis of the NA gene showed that the H5N1 strains isolated from the two outbreaks were not originated from the same source. The first Indian isolate (Nandubar/7972/06) was clustered closest to an isolate from chicken in Vietnam in 2004, whereas the second Indian isolate (Jalgaon/8824/06) showed resemblance to strains isolated from swan in Italy and Iran in 2006. Moreover, amino acid sequence analysis showed varying hot spots for substitutions between these two Indian isolates, and three substitutions were found at functional domain sites. Secondary structure changes due to these substitutions were also reported. This study reveals that the H5N1 strains isolated from chickens during 2006 bird flu outbreaks in two neighboring districts of Maharashtra, India are genetically different.

  13. Rapid microsatellite identification from Illumina paired-end genomic sequencing in two birds and a snake.

    Directory of Open Access Journals (Sweden)

    Todd A Castoe

    Full Text Available Identification of microsatellites, or simple sequence repeats (SSRs, can be a time-consuming and costly investment requiring enrichment, cloning, and sequencing of candidate loci. Recently, however, high throughput sequencing (with or without prior enrichment for specific SSR loci has been utilized to identify SSR loci. The direct "Seq-to-SSR" approach has an advantage over enrichment-based strategies in that it does not require a priori selection of particular motifs, or prior knowledge of genomic SSR content. It has been more expensive per SSR locus recovered, however, particularly for genomes with few SSR loci, such as bird genomes. The longer but relatively more expensive 454 reads have been preferred over less expensive Illumina reads. Here, we use Illumina paired-end sequence data to identify potentially amplifiable SSR loci (PALs from a snake (the Burmese python, Python molurus bivittatus, and directly compare these results to those from 454 data. We also compare the python results to results from Illumina sequencing of two bird genomes (Gunnison Sage-grouse, Centrocercus minimus, and Clark's Nutcracker, Nucifraga columbiana, which have considerably fewer SSRs than the python. We show that direct Illumina Seq-to-SSR can identify and characterize thousands of potentially amplifiable SSR loci for as little as $10 per sample--a fraction of the cost of 454 sequencing. Given that Illumina Seq-to-SSR is effective, inexpensive, and reliable even for species such as birds that have few SSR loci, it seems that there are now few situations for which prior hybridization is justifiable.

    conducted using the Medline, MD Consult, HighWire, Medscape and Literatura Latinoamericana y del Caribe en Ciencias de la Salud (LILACS, Latin American and Caribbean Health Sciences Literature databases, as well as through direct research, limiting the scope to articles published within the past 10 years. We selected 31 original articles addressing the recent outbreaks of infection with the H5N1 subtype of avian influenza A in domesticated birds in Asia, which have resulted in significant economic losses and repercussions for public health, as well as some cases of human infection presenting high lethality. In most cases, infection has been associated with direct exposure to infected birds or contact with surfaces infected with bird excrement. However, cases of human-to-human transmission have been confirmed. In those cases, the incubation period varied from 2 to 4 days. The clinical manifestations range from asymptomatic infection to mild upper airway disease, pneumonia and multiple organ failure. Chest X-rays may reveal bilateral interstitial infiltrate, lobar collapse, focal consolidation and air bronchogram without pleural effusion. Lymphopenia is indicative of a poor prognosis. Supportive care appears to be the only acceptable treatment. Risk factors for poor prognosis include advanced age, delayed hospitalization, lower airway involvement, low white blood cell count or lymphopenia upon admission. Controlling outbreaks in domestic fowl and limiting contact between humans and infected birds must be the priorities in the management of this disease at the public health level. In addition, techniques and knowledge regarding the disease should be widely disseminated.

    Full Text Available In periods of seasonal influenza, during pandemic flu in the past and from recent experience that we have the emergence of influenza A (H1N1, pregnant compared with non-pregnant women are at increased risk to get sick and to develop serious complications up to mortality. Purpose: This paper examines the risks that arise for pregnant from contamination with the flu virus and the safety of influenza vaccination in pregnancy. Method: The method involves searching review and research studies in Pubmed data base mainly of the 2000 until 2009 and the words were used is pregnancy, flu vaccination, complications of the flu vaccination at the period of pregnancy. Results: Morbidity during periods of seasonal influenza in pregnant women is increased, while in times of pandemic are recorded fatalities. Based on this, specific recommendations have been made for a flu vaccination in pregnant women, both from the CDC, the American College of Obstetricians and Gynecologists in the U.S. and other official bodies like the World Health Organization, according to that the constitution of influenza vaccine in the pregnancy is necessary, given that the probability of morbidity in this period is increased at 10%. Conclusions: The studies so far to influenza vaccination in pregnancy, do not record serious complications for pregnant women and infants. However more research needs to be done on the safety of influenza vaccination in pregnancy.

    最近科学家们对禽流感有了进一步的认识。他们发现,普通流感病毒位于人类上呼吸道内,当人们咳嗽或者打喷嚏时,这些病毒会轻而易举地被喷出体外,使得其他人极易受到感染;而H5N1型禽流感病毒则大多位于人体的肺部细胞中,由于在人类呼吸道中聚集的位置太过靠下,所以很难在人们咳嗽或打喷嚏的过程中离开人体进入空气中,这就为H5N1难于人际传染找到了最新依据。尽管如此,我们不能排除这种病毒发生变异的可能性,所以应继续对其保持警惕,绝不能掉以轻心。

  17. FLU, an amino acid substitution model for influenza proteins

    Directory of Open Access Journals (Sweden)

    Gascuel Olivier

    2010-04-01

    Full Text Available Abstract Background The amino acid substitution model is the core component of many protein analysis systems such as sequence similarity search, sequence alignment, and phylogenetic inference. Although several general amino acid substitution models have been estimated from large and diverse protein databases, they remain inappropriate for analyzing specific species, e.g., viruses. Emerging epidemics of influenza viruses raise the need for comprehensive studies of these dangerous viruses. We propose an influenza-specific amino acid substitution model to enhance the understanding of the evolution of influenza viruses. Results A maximum likelihood approach was applied to estimate an amino acid substitution model (FLU from ~113, 000 influenza protein sequences, consisting of ~20 million residues. FLU outperforms 14 widely used models in constructing maximum likelihood phylogenetic trees for the majority of influenza protein alignments. On average, FLU gains ~42 log likelihood points with an alignment of 300 sites. Moreover, topologies of trees constructed using FLU and other models are frequently different. FLU does indeed have an impact on likelihood improvement as well as tree topologies. It was implemented in PhyML and can be downloaded from ftp://ftp.sanger.ac.uk/pub/1000genomes/lsq/FLU or included in PhyML 3.0 server at http://www.atgc-montpellier.fr/phyml/. Conclusions FLU should be useful for any influenza protein analysis system which requires an accurate description of amino acid substitutions.

    The epidemic situation of A H1N1 flu arose in North America in April 2009,which rapidly expanded to three continents of Europe,Asia and Africa,with the risk ranking up to 5.Until May 13th,the flu virus of A H1N1 had spread into 33 countries and regions,with a laboratory confirmed case number of 5728,including 61 deaths.Based on IRV and EpiFluDB database,425 parts of A H1N1 flu virus sequence were achieved,followed by sequenced comparison and evolution analysis.The results showed that the current predominant A H1N1 flu virus was a kind of triple reassortment A flu virus:(i) HA,NA,MP,NP and NS originated from swine influenza virus;PB2 and PA originated from bird influenza virus;PB1 originated from human influenza virus.(ii) The origin of swine influenza virus could be subdivided as follows:HA,NP and NS originated from classic swine influenza virus of H1N1 subtype;NA and MP originated from bird origin swine influenza virus of H1N1 subtype.(iii) A H1N1 flu virus experienced no significant mutation during the epidemic spread,accompanied with no reassortment of the virus genome.In the paper,the region of the representative strains for sequence analysis (A/California/04/2009 (H1N1) and A/Mexico/4486/2009 (H1N1)) included USA and Mexico and was relatively wide,which suggested that the analysis results were convincing.

    Comparative genomics continues illuminating amniote genome evolution, but for many lineages our understanding remains incomplete. Here, we refine the assembly (CPI 3.0.3 NCBI AHGY00000000.2) and develop a cytogenetic map of the painted turtle (Chrysemys picta-CPI) genome, the first in turtles and in vertebrates with temperature-dependent sex determination. A comparison of turtle genomes with those of chicken, selected nonavian reptiles, and human revealed shared and novel genomic features, such as numerous chromosomal rearrangements. The largest conserved syntenic blocks between birds and turtles exist in four macrochromosomes, whereas rearrangements were evident in these and other chromosomes, disproving that turtles and birds retain fully conserved macrochromosomes for greater than 300 Myr. C-banding revealed large heterochromatic blocks in the centromeric region of only few chromosomes. The nucleolar-organizing region (NOR) mapped to a single CPI microchromosome, whereas in some turtles and lizards the NOR maps to nonhomologous sex-chromosomes, thus revealing independent translocations of the NOR in various reptilian lineages. There was no evidence for recent chromosomal fusions as interstitial telomeric-DNA was absent. Some repeat elements (CR1-like, Gypsy) were enriched in the centromeres of five chromosomes, whereas others were widespread in the CPI genome. Bacterial artificial chromosome (BAC) clones were hybridized to 18 of the 25 CPI chromosomes and anchored to a G-banded ideogram. Several CPI sex-determining genes mapped to five chromosomes, and homology was detected between yet other CPI autosomes and the globally nonhomologous sex chromosomes of chicken, other turtles, and squamates, underscoring the independent evolution of vertebrate sex-determining mechanisms.

  16. A Fast Test to Diagnose Flu

    Energy Technology Data Exchange (ETDEWEB)

    Hazi, A U

    2007-02-12

    People with flu-like symptoms who seek treatment at a medical clinic or hospital often must wait several hours before being examined, possibly exposing many people to an infectious virus. If a patient appears to need more than the routine fluids-and-rest prescription, effective diagnosis requires tests that must be sent to a laboratory. Hours or days may pass before results are available to the doctor, who in the meantime must make an educated guess about the patient's illness. The lengthy diagnostic process places a heavy burden on medical laboratories and can result in improper use of antibiotics or a costly hospital stay. A faster testing method may soon be available. An assay developed by a team of Livermore scientists can diagnose influenza and other respiratory viruses in about two hours once a sample has been taken. Unlike other systems that operate this quickly, the new device, called FluIDx (and pronounced ''fluidics''), can differentiate five types of respiratory viruses, including influenza. FluIDx can analyze samples at the point of patient care--in hospital emergency departments and clinics--allowing medical providers to quickly determine how best to treat a patient, saving time and potentially thousands of dollars per patient. The FluIDx project, which is led by Livermore chemist Mary McBride of the Physics and Advanced Technologies Directorate, received funding from the National Institute of Allergy and Infectious Diseases and the Laboratory Directed Research and Development (LDRD) Program. To test the system and make it as useful as possible, the team worked closely with the Emergency Department staff at the University of California (UC) at Davis Medical Center in Sacramento. Flu kills more than 35,000 people every year in the US. The 2003 outbreak of severe acute respiratory syndrome and the ongoing concern about a possible bird flu pandemic show the need for a fast, reliable test that can differentiate seasonal flu from a

  2. Early warning: Avian flu and nuclear science

    International Nuclear Information System (INIS)

    Avian flu has spread to 51 countries, 36 this year alone, many of which are densely populated and deprived. The joint FAO/IAEA programme is working on the rapid detection of emerging diseases, including bird flu, and using nuclear and radiation techniques in the process. The problems are serious and challenging, but nuclear technologies may offer a solution. For most developing countries, TAD (transboundary animal diseases) detection is still vital. The bottleneck is their inability to rapidly detect the virus and to determine early enough whether it is H5N1 or another subtype, so that authorities can take appropriate control measures. Serious efforts are focused on the early detection of the agents. Timely recognition of such viral infections would prevent the spread of the diseases to large animal populations in huge geographic areas. Thus, the development of novel, powerful diagnostic nuclear and nuclear-related assays is a crucial issue today in veterinary research and animal health care. Molecular virology offers a range of new methods, which are able to accelerate and improve the diagnosis of infectious diseases in animals and in man. The molecular detection assays, like the polymerase chain reaction (PCR) technologies, provide possibilities for a very rapid diagnosis. The detection of viruses can be completed within hours or hopefully even within minutes with a sensitivity level of less than one pathogenic organism. Molecular approaches have contributed significantly to the rapid detection of well-established, as well as newly emerging, infectious agents such as Nipah and Hendra viruses or corona viruses in the SARS scenario and the detection and molecular characterisation of the highly pathogenic avian influenza H5N1 subtype that threatens the world today. The nucleic acid amplification assays, although they were at first expensive and cumbersome, have become relatively cheap and user-friendly tools in the diagnostic laboratories

    Full Text Available Abstract If and when sustained human-to-human transmission of H5N1 becomes a reality, the world will no longer be dealing with sporadic avian flu borne along migratory flight paths of birds, but aviation flu – winged at subsonic speed along commercial air conduits to every corner of planet Earth. Given that air transportation is the one feature that most differentiates present day transmission scenarios from those in 1918, our present inability to prevent spread of influenza by international air travel, as reckoned by the World Health Organization, constitutes a major weakness in the current global preparedness plan against pandemic flu. Despite the lessons of SARS, it is surprising that aviation-related health policy options have not been more rigorously evaluated, or scientific research aimed at strengthening public health measures on the air transportation front, more energetically pursued.

    By the beginning of July 2009 the West Midlands had seen more cases of novel H1N1 influenza (swine flu) than any other region in the U.K. Over a three-week period almost 850 people presented to Heartlands Hospital with flu-like symptoms. Of those admitted 52 adults were subsequently confirmed as having H1N1 infection. Most were younger than 30 and not from traditional influenza risk groups. The main risk factor for severe disease was asthma, and to a lesser extent pregnancy and obesity. Seven patients were admitted to intensive care and five developed an acute lung injury requiring prolonged admission. Two patients required extra corporeal membrane oxygenation and one died. Despite increased workload normal clinical services were unaffected. The hospital was not closed to admissions nor was it paralysed by staff absence. With a predicted second wave expected at the end of 2009, efforts to maintain effective community assessment remain crucial.

    2009-07-01

    Full Text Available Abstract Background With the publication of the draft chicken genome and the recent production of several BAC clone libraries from non-avian reptiles and birds, it is now possible to undertake more detailed comparative genomic studies in Reptilia. Of interest in particular are the genomic events that transformed the large, repeat-rich genomes of mammals and non-avian reptiles into the minimalist chicken genome. We have used paired BAC end sequences (BESs from the American alligator (Alligator mississippiensis, painted turtle (Chrysemys picta and emu (Dromaius novaehollandiae to investigate patterns of sequence divergence, gene and retroelement content, and microsynteny between these species and chicken. Results From a total of 11,967 curated BESs, we successfully mapped 725, 773 and 2597 sequences in alligator, turtle, and emu, respectively, to sites in the draft chicken genome using a stringent BLAST protocol. Most commonly, sequences mapped to a single site in the chicken genome. Of 1675, 1828 and 2936 paired BESs obtained for alligator, turtle, and emu, respectively, a total of 34 (alligator, 2%, 24 (turtle, 1.3% and 479 (emu, 16.3% pairs were found to map with high confidence and in the correct orientation and with BAC-sized intermarker distances to single chicken chromosomes, including 25 such paired hits in emu mapping to the chicken Z chromosome. By determining the insert sizes of a subset of BAC clones from these three species, we also found a significant correlation between the intermarker distance in alligator and turtle and in chicken, with slopes as expected on the basis of the ratio of the genome sizes. Conclusion Our results suggest that a large number of small-scale chromosomal rearrangements and deletions in the lineage leading to chicken have drastically reduced the number of detected syntenies observed between the chicken and alligator, turtle, and emu genomes and imply that small deletions occurring widely throughout the

  17. Comparative genomics in chicken and Pekin duck using FISH mapping and microarray analysis

    2009-08-01

    Full Text Available Abstract Background The availability of the complete chicken (Gallus gallus genome sequence as well as a large number of chicken probes for fluorescent in-situ hybridization (FISH and microarray resources facilitate comparative genomic studies between chicken and other bird species. In a previous study, we provided a comprehensive cytogenetic map for the turkey (Meleagris gallopavo and the first analysis of copy number variants (CNVs in birds. Here, we extend this approach to the Pekin duck (Anas platyrhynchos, an obvious target for comparative genomic studies due to its agricultural importance and resistance to avian flu. Results We provide a detailed molecular cytogenetic map of the duck genome through FISH assignment of 155 chicken clones. We identified one inter- and six intrachromosomal rearrangements between chicken and duck macrochromosomes and demonstrated conserved synteny among all microchromosomes analysed. Array comparative genomic hybridisation revealed 32 CNVs, of which 5 overlap previously designated "hotspot" regions between chicken and turkey. Conclusion Our results suggest extensive conservation of avian genomes across 90 million years of evolution in both macro- and microchromosomes. The data on CNVs between chicken and duck extends previous analyses in chicken and turkey and supports the hypotheses that avian genomes contain fewer CNVs than mammalian genomes and that genomes of evolutionarily distant species share regions of copy number variation ("CNV hotspots". Our results will expedite duck genomics, assist marker development and highlight areas of interest for future evolutionary and functional studies.

  18. Domestication and the mitochondrial genome: comparing patterns and rates of molecular evolution in domesticated mammals and birds and their wild relatives.

    Studies of domesticated animals have led to the suggestion that domestication could have significant effects on patterns of molecular evolution. In particular, analyses of mitochondrial genome sequences from domestic dogs and yaks have yielded higher ratios of non-synonymous to synonymous substitutions in the domesticated lineages than in their wild relatives. These results are important because they imply that changes to selection or population size operating over a short timescale can cause significant changes to the patterns of mitochondrial molecular evolution. In this study, our aim is to test whether the impact on mitochondrial genome evolution is a general feature of domestication or whether it is specific to particular examples. We test whether domesticated mammals and birds have consistently different patterns of molecular evolution than their wild relatives for 16 phylogenetically independent comparisons of mitochondrial genome sequences. We find no consistent difference in branch lengths or dN/dS between domesticated and wild lineages. We also find no evidence that our failure to detect a consistent pattern is due to the short timescales involved or low genetic distance between domesticated lineages and their wild relatives. However, removing comparisons where the wild relative may also have undergone a bottleneck does reveal a pattern consistent with reduced effective population size in domesticated lineages. Our results suggest that, although some domesticated lineages may have undergone changes to selective regime or effective population size that could have affected mitochondrial evolution, it is not possible to generalize these patterns over all domesticated mammals and birds.

    Because it is not easy to differentiate Influenza virus (Flu) from RS virus (RSV) just by clinical symptoms, to accurately diagnose those viruses in conjunction with patient's clinical symptoms, rapid diagnostic kits has been used separately for each of those viruses. In our new study, we have developed a new rapid diagnostic kit, QuickNavi™-Flu+RSV. The kit can detect Flu A, Flu B, and RSV antigens with a single sample collection and an assay. Total of 2,873 cases (including nasopharyngeal swabs and nasopharyngeal aspirates specimens) in 2010/2011 and 2011/2012 seasons were evaluated with QuickNavi™-Flu+RSV and a commercially available kit. Sensitivity, specificity, and accuracy of Flu type A, type B, and RSV were above 95% when compared to commercially available kits (QuickNavi™-Flu and QuickNavi™-RSV) and considered to be equivalent to the commercially available kits. In 2011/2012 season, RSV infections increased prior to Flu season and continued during the peak of the Flu season. The kit can contribute to accurate diagnosis of Flu and RSV infections since co-infection cases have also been reported during the 2011/2012 season. QuickNavi™-Flu+RSV is useful for differential diagnosis of respiratory infectious diseases since it can detect Flu type A, type B, and RSV virus antigens with a single sample collection.

    Jingjing Wang

    Full Text Available The genomes of six pigeon paramyxovirus type 1 (PPMV-1 isolated from symptomless pigeons in live poultry markets during the national active surveillance from 2011 to 2013 were sequenced and analyzed in this study. The complete genome lengths of all isolates were 15,192 nucleotides with the gene order of 3'-NP-P-M-F-HN-L-5'. All isolates had the same motif of 112RRQKRF117 at the cleavage site of the fusion protein, which was typical of velogenic Newcastle disease virus (NDV. Several mutations were identified in the functional domains of F and HN proteins, including fusion peptide, heptad repeat region, transmembrane domains and neutralizing epitopes. Phylogenetic analysis based on sequences of complete genomes and six genes revealed that all isolates belonged to genotype VI in class II, but at least 2 sub-genotypes were identified. Most isolates were placed into sub-genotype VIb with the exception of pi/GX/1015/13, which was classified in sub-genotype VIa. The obvious antigenic difference between PPMV-1 isolates and La Sota strain was found based on the R-value calculated by cross hemagglutination inhibition (HI assay. These results provided the evidence that PPMV-1 could be detected from healthy pigeons, and our study may be useful in designing vaccines used in pigeon, and developing molecular diagnostic tools to monitor and prevent future PPMV-1 outbreaks.

    2013-01-01

    Objective We sought to develop a practical influenza forecast model, based on real-time, geographically focused, and easy to access data, to provide individual medical centers with advanced warning of the number of influenza cases, thus allowing sufficient time to implement an intervention. Secondly, we evaluated how the addition of a real-time influenza surveillance system, Google Flu Trends, would impact the forecasting capabilities of this model. Introduction Each year, influenza results in increased Emergency Department crowding which can be mitigated through early detection linked to an appropriate response. Although current surveillance systems, such as Google Flu Trends, yield near real-time influenza surveillance, few demonstrate ability to forecast impending influenza cases. Methods Forecasting models designed to predict one week in advance were developed from weekly counts of confirmed influenza cases over seven seasons (2004 – 2011) divided into training and out-of-sample verification sets. Forecasting procedures using classical Box-Jenkins, generalized linear, and autoregressive methods were employed to develop the final model and assess the relative contribution of external variables such as, Google Flu Trends, meteorological data, and temporal information. Models were developed and evaluated through statistical measures of global deviance and log-likelihood ratio tests. An additional measure of forecast confidence, defined as the percentage of forecast values, during an influenza peak, that are within 7 influenza cases of the actual data, was examined to demonstrate practical utility of the model. Results A generalized autoregressive Poisson (GARMA) forecast model integrating previous influenza cases with Google Flu Trends information provided the most accurate influenza case predictions. Google Flu Trend data was the only source of external information providing significant forecast improvements (p = 0.00002). The final model, a GARMA intercept

    Full Text Available BACKGROUND: We developed a practical influenza forecast model based on real-time, geographically focused, and easy to access data, designed to provide individual medical centers with advanced warning of the expected number of influenza cases, thus allowing for sufficient time to implement interventions. Secondly, we evaluated the effects of incorporating a real-time influenza surveillance system, Google Flu Trends, and meteorological and temporal information on forecast accuracy. METHODS: Forecast models designed to predict one week in advance were developed from weekly counts of confirmed influenza cases over seven seasons (2004-2011 divided into seven training and out-of-sample verification sets. Forecasting procedures using classical Box-Jenkins, generalized linear models (GLM, and generalized linear autoregressive moving average (GARMA methods were employed to develop the final model and assess the relative contribution of external variables such as, Google Flu Trends, meteorological data, and temporal information. RESULTS: A GARMA(3,0 forecast model with Negative Binomial distribution integrating Google Flu Trends information provided the most accurate influenza case predictions. The model, on the average, predicts weekly influenza cases during 7 out-of-sample outbreaks within 7 cases for 83% of estimates. Google Flu Trend data was the only source of external information to provide statistically significant forecast improvements over the base model in four of the seven out-of-sample verification sets. Overall, the p-value of adding this external information to the model is 0.0005. The other exogenous variables did not yield a statistically significant improvement in any of the verification sets. CONCLUSIONS: Integer-valued autoregression of influenza cases provides a strong base forecast model, which is enhanced by the addition of Google Flu Trends confirming the predictive capabilities of search query based syndromic surveillance.

    Full Text Available Abstract In order to study duck microsatellites, we constructed a library enriched for (CAn, (CAGn, (GCCn and (TTTCn. A total of 35 pairs of primers from these microsatellites were developed and used to detect polymorphisms in 31 unrelated Peking ducks. Twenty-eight loci were polymorphic and seven loci were monomorphic. A total of 117 alleles were observed from these polymorphic microsatellite markers, which ranged from 2 to 14 with an average of 4.18 per locus. The frequencies of the 117 alleles ranged from 0.02 to 0.98. The highest heterozygosity (0.97 was observed at the CAUD019 microsatellite locus and the lowest heterozygosity (0.04 at the CAUD008 locus, and 11 loci had heterozygosities greater than 0.50 (46.43%. The polymorphism information content (PIC of 28 loci ranged from 0.04 to 0.88 with an average of 0.42. All the above markers were used to screen the polymorphism in other bird species. Two markers produced specific monomorphic products with the chicken DNA. Fourteen markers generated specific fragments with the goose DNA: 5 were polymorphic and 9 were monomorphic. But no specific product was detected with the peacock DNA. Based on sequence comparisons of the flanking sequence and repeat, we conclude that 2 chicken loci and 14 goose loci were true homologous loci of the duck loci. The microsatellite markers identified and characterized in the present study will contribute to the genetic map, quantitative traits mapping, and phylogenetic analysis in the duck and goose.

    The genus Kobuvirus (Picornaviridae) consists of three species, Aichivirus A (e.g., Aichi virus, which infects humans), Aichivirus B and Aichivirus C. Kobuvirus have not been detected in non-mammal species including birds. In this study, a novel kobuvirus was identified in 3 (17 %) out of 18 faecal samples collected from European rollers (Coracias garrulus) in Hungary. The complete genome sequence of strain SZAL6-KoV/2011/HUN (KJ934637), which was determined using a novel 5'/3' RACE method (dsRNA-RACE) involving a double-stranded (ds)RNA intermediate, has a type-V IRES at the 5' end and a cis-acting element (CRE) in the 3C gene and encodes L and 2A(H-box/NC) proteins, but it does not contain the sequence forming a "barbell-like" secondary RNA structure in the 3'UTR. SZAL6-KoV/2011/HUN has 72 %, 73 %, and 81 % amino acid sequence identity to the P1, P2, and P3 protein, respectively, of Aichi virus. Evolutionary analysis showed that SZAL6-KoV/2011/HUN shares a common ancestor with other kobuviruses but belongs to a more ancient lineage in the species Aichivirus A. Investigation of the known kobuviruses in different animals and discovery of novel kobuviruses in potential host species helps to clarify the evolutionary connection and zoonotic potential of kobuviruses.

    A simulation exercise aimed at assessing the management and provision of ambulatory care in the context of a highly pathogenic influenza pandemic was conducted in a specifically dedicated consultation center (Centre de Consultation Dédié (CCD) à la grippe) based on official French guidelines. The exercise was carried out in a school in Paris equipped to simulate a "flu clinic". 3 practitioners provided treatment lasting 2 hours to nursing students acting as patients. The exercise highlighted a number of major organizational issues. Staff were found to be unable to manage the center and to perform patient transfers; face masks were not routinely and consistently worn by doctors and patients; and communication between professionals within the clinic was limited. The exercise showed that much remains to be done to ensure that "flu clinics" are effective and functional. The results suggest that the exercise will need to be repeated on a larger scale and over a longer period. PMID:22365047

This increased the output of influenza virus sequence data as well as the research publication and other reports. In order to fight against H5N1 avian flu in a comprehensive way, we designed and started to set up the Website for Avian Flu Information (http://www.avian-flu.info) from 2004. Other than the influenza virus database available, the website is aiming to integrate diversified information for both researchers and the public. From 2004 to 2009, we collected information from all aspects, i.e. reports of outbreaks, scientific publications and editorials, policies for prevention, medicines and vaccines, clinic and diagnosis. Except for publications, all information is in Chinese. Till April 15, 2009, the cumulative news entries had been over 2000 and research papers were approaching 5000. By using the curated data from Influenza Virus Resource, we have set up an influenza virus sequence database and a bioinformatic platform, providing the basic functions for the sequence analysis of influenza virus. We will focus on the collection of experimental data and results as well as the integration of the data from the geological information system and avian influenza epidemiology.

    Please cite this paper as: Devroey et al. (2011) Online monitoring of flu in Belgium. Influenza and Other Respiratory Viruses 5(5), 351–356. Background  The diagnosis and treatment of patients with the A(H1N1) pandemic flu caused some serious burden for general practitioners (GPs) in the summer and autumn of 2009. Objective  The aim of this study was to track the incidence of influenza and influenza‐like illness (ILI) in Belgium and to describe the characteristics of the affected patients. Methods  In July 2009, the Belgian online influenza surveillance system (BOISS) was set up to monitor the spread of influenza and ILI. Registrations were made by 93 GPs from all 10 Belgian provinces who participated at least 1 week during the first 12 months of the registration. Only patients who met the WHO criteria for flu were recorded. Results  In total, 1254 patients (53% men) with influenza or ILI were included. Mainly younger persons were affected: 43% was under the age of 20 years. A risk factor for influenza‐related complications was determined in 19% of cases, mainly patients with chronic respiratory problems. A treatment with oseltamivir or zanamivir was prescribed in 13%, and 3% of the patients was admitted to a hospital. The time of the peak incidence (44th week) and the magnitude (623 cases per week per 100 000 inhabitants) corresponded with the figures of the existing paper‐based registration network. The small sample size and possible reporting biases may have influenced the findings of the study. Conclusions  The BOISS provides a good alternative to conduct surveillance activities for influenza and ILI in Belgium. It provides complementary information regarding ILI compared to the existing data capturing. PMID:21668686

This research is the second step of my research deal with Avian flu and the economy.The first step was the negative impact of avian flu on economy which was already published on Asian Social Economic Journal by last year. The result of this research are : On the micro level in domestic market there are decresed production and increased prices in the poultry sector, eggs, other farms, restaurants and services. While in the foreign market there are decresed exports as well as imports. Similarly, there is a decline in consumption by the entire group of household due to a decline in the acceptance by all groups of households and firms. Government revenue also declined due to a decrease in taxes from households and firms.At the macro level there are a decline in GDP and a decline in the investment. The last  simulation illustrate  the increase of production and the impact of government policy on the micro aspects and the overall economy.  On the micro level in domestic market there are increased production and falling prices in the sector of poultry, eggs, other farms, restaurants and services. While in foreign market there are  increased exports and  decreased imports in almost all sectors.

  13. Developmental characterization and chromosomal mapping of the 5-azacytidine-sensitive fluF locus of Aspergillus nidulans.

    Tamame, M; Antequera, F; Santos, E

    1988-01-01

    In Aspergillus nidulans, a fungus that possesses negligible, if any, levels of methylation in its genome, low concentrations of 5-azacytidine (5-AC) convert a high percentage of the cell population to fluffy phenotypic variants through a heritable modification of a single nuclear gene (M. Tamame, F. Antequera, J. R. Villanueva, and T. Santos, Mol. Cell. Biol. 3:2287-2297, 1983). This new 5-AC-altered locus, designated here fluF1, was mapped as the closest marker to the centromere that has been identified so far on the right arm of chromosome VIII. Of all mutagens tested, only 5-AC induced the fluffy phenotype with a significant frequency. Furthermore, we determined that the wild-type, dominant allele of the fluF gene was primarily accessible to modification by 5-AC at the initial stages of fungal vegetative growth. These results indicated that 5-AC does not act through random mutagenic action but, rather, that fluF constitutes a specific target for this drug during a well-defined period of fungal development. Alteration of fluF by 5-AC resulted in a dramatic modification of the developmental program of A. nidulans. The resulting fluffy clones were characterized by massive, uncontrolled proliferation of undifferentiated hyphae, a drastic delay in the onset of asexual differentiation (conidiation), and colonies with an invasive nature. These features are reminiscent of the malignant properties of tumor cells. We propose that the locus fluF plays a primary role in the control of cell proliferation in A. nidulans and that its alteration by 5-AC produces pleiotropic modifications of the developmental program of this fungus.

    The history of the 1957/58 Asian flu in Germany is systematically presented for the first time. The focus is on flu vaccination, which is discussed as a yardstick of the perception of the pandemic. International expertise on influenza virology was predominantly based in Anglo-Saxon countries. German microbiologists issued no clear recommendation for preventative vaccination until 1960. Instead, quinine was relied upon as the traditional medicinal prophylaxis. Antibiotics were more frequently administered. In East Germany, little fuss was made over the Asian flu. In line with the authorities' social hygiene orientation, vaccination was accepted as a matter of principle. In the Federal Republic and West Berlin, the population rejected the vaccination largely. It was seen as a scandal that many employees were on sick leave because of the flu, thus adversely affecting the economy. PMID:24844113

    禽流感是一种禽类的烈性传染病,在世界范围内广泛流传,严重威胁着养禽业.尤其是高致病性禽流感的流行,病死率极高,常常使国家和人民蒙受巨大的经济损失.禽流感的传染性极强,并可跨物种进行传播,禽流感作为一种全新的病种,已成为人类健康和生命的严重威胁,而面对禽流感病毒的侵害,人类自身却毫无免疫防护,所以必须加强禽流感的预防.由于禽流感病毒广泛存在于各种禽类和野生鸟类体内,因此禽流感的控制是一项长期艰巨的任务,疫苗的开发和使用是应对这项艰巨任务最实际、最有效和最经济的手段.理想的疫苗应该是在具备良好的安全性的前提下,不仅能够调动机体的体液免疫,产生病毒中和抗体,更能够充分调动机体的细胞免疫来充分发挥病毒清除机制.%Avian flu is a deadly infectious disease of poultry,which widespreads in the world and is a serious threat to the poultry industry. With high mortality,highly pathogenic avian influenza often makes the country and people suffer great economic losses. Avian flu has cross-species transmission due to the strong contagiousness. As a new disease,avian flu has become a serious threat to human health and life.Yet the human beings have no immune protection when facing to the virus, it is necessary to strengthen prevention of avian flu. As the avian flu virus widely exists in the bodies of a variety of poultry and wild bird,the control of avian flu becomes a long-term and arduous task. The development and use of vaccine are the most practical,effective and economical measures for it. In the premise of good safety, the ideal vaccine can not only mobilize the body's humoral immunity to produce virus-neutralizing antibodies, but also fully mobilize the cellular immunity to remove virus.

  18. Reconstructing the Phylogenetic History of Long-Term Effective Population Size and Life-History Traits Using Patterns of Amino Acid Replacement in Mitochondrial Genomes of Mammals and Birds

    The nearly neutral theory, which proposes that most mutations are deleterious or close to neutral, predicts that the ratio of nonsynonymous over synonymous substitution rates (dN/dS), and potentially also the ratio of radical over conservative amino acid replacement rates (Kr/Kc), are negatively correlated with effective population size. Previous empirical tests, using life-history traits (LHT) such as body-size or generation-time as proxies for population size, have been consistent with these predictions. This suggests that large-scale phylogenetic reconstructions of dN/dS or Kr/Kc might reveal interesting macroevolutionary patterns in the variation in effective population size among lineages. In this work, we further develop an integrative probabilistic framework for phylogenetic covariance analysis introduced previously, so as to estimate the correlation patterns between dN/dS, Kr/Kc, and three LHT, in mitochondrial genomes of birds and mammals. Kr/Kc displays stronger and more stable correlations with LHT than does dN/dS, which we interpret as a greater robustness of Kr/Kc, compared with dN/dS, the latter being confounded by the high saturation of the synonymous substitution rate in mitochondrial genomes. The correlation of Kr/Kc with LHT was robust when controlling for the potentially confounding effects of nucleotide compositional variation between taxa. The positive correlation of the mitochondrial Kr/Kc with LHT is compatible with previous reports, and with a nearly neutral interpretation, although alternative explanations are also possible. The Kr/Kc model was finally used for reconstructing life-history evolution in birds and mammals. This analysis suggests a fairly large-bodied ancestor in both groups. In birds, life-history evolution seems to have occurred mainly through size reduction in Neoavian birds, whereas in placental mammals, body mass evolution shows disparate trends across subclades. Altogether, our work represents a further step toward a more

  19. FluShuffle and FluResort: new algorithms to identify reassorted strains of the influenza virus by mass spectrometry

    Full Text Available Abstract Background Influenza is one of the oldest and deadliest infectious diseases known to man. Reassorted strains of the virus pose the greatest risk to both human and animal health and have been associated with all pandemics of the past century, with the possible exception of the 1918 pandemic, resulting in tens of millions of deaths. We have developed and tested new computer algorithms, FluShuffle and FluResort, which enable reassorted viruses to be identified by the most rapid and direct means possible. These algorithms enable reassorted influenza, and other, viruses to be rapidly identified to allow prevention strategies and treatments to be more efficiently implemented. Results The FluShuffle and FluResort algorithms were tested with both experimental and simulated mass spectra of whole virus digests. FluShuffle considers different combinations of viral protein identities that match the mass spectral data using a Gibbs sampling algorithm employing a mixed protein Markov chain Monte Carlo (MCMC method. FluResort utilizes those identities to calculate the weighted distance of each across two or more different phylogenetic trees constructed through viral protein sequence alignments. Each weighted mean distance value is normalized by conversion to a Z-score to establish a reassorted strain. Conclusions The new FluShuffle and FluResort algorithms can correctly identify the origins of influenza viral proteins and the number of reassortment events required to produce the strains from the high resolution mass spectral data of whole virus proteolytic digestions. This has been demonstrated in the case of constructed vaccine strains as well as common human seasonal strains of the virus. The algorithms significantly improve the capability of the proteotyping approach to identify reassorted viruses that pose the greatest pandemic risk.

    This paper studies consumer learning in influenza vaccination decisions. We examine consumer learning in influenza vaccine demand within a reduced form instrumental variable framework that exploits differences in risk characteristics of different influenza viruses as a natural experiment to distinguish the effects of learning based on previous influenza vaccination experiences from unobserved heterogeneity. The emergence of a new virus strain (influenza A H1N1/09) during the 2009 'Swine flu' pandemic resulted in two different vaccines being recommended for distinct population subgroups with some people, who were not usually targeted by seasonal vaccination programs, being specifically recommended for the new Swine flu vaccine. We use these differences in vaccination targeting to construct instrumental variables for estimating the effect of past influenza vaccination experiences on the demand for pandemic vaccine. We find large causal effects of previous seasonal vaccination on pandemic vaccination. Causal effects of past influenza vaccination experiences on perceived vaccination safety are likely to be an important pathway linking past vaccination experiences with future vaccine uptake. Our results suggest a significant role of learning in vaccination decisions. Current efforts to expand seasonal vaccination may thus have potentially important long-term effects on future influenza vaccination levels and pandemic preparedness.

    The 2009 flu pandemic was a global outbreak of a new strain of H1N1 influenza virus often referred colloquially as "swine flu". The objectives of the study were: (1) To know the sociodemographic and awareness profile of visitors attending swine flu screening booths. (2) To reveal sources of information. The present cross-sectional study was undertaken among the visitors (18 years and above) attending swine flu screening booths organised within the Belgaum city during Ganesh festival from 28-08-2009 to 03-09-2009 by interviewing them using predesigned, pretested structured questionnaire on swine flu. The data was collected and analysed using SPSS software programme for windows (version 16). Chi-square test was applied. Out of 206 visitors, 132 (64.1%) were males and 107 (51.9%) were in the age group of 30-49 years; 183 (88.8%) had heard about swine flu. More than a third of the visitors (38.3%) disclosed that there was a vaccine to prevent swine flu. Majority responded that it could be transmitted by being in close proximity to pigs (49.0%) and by eating pork (51.5%). Newspaper/magazine (64.6%), television (61.7%), and public posters/pamphlets (44.2%) were common sources of information. The present study revealed that doctors/public health workers have played little role in creating awareness in the community. The improved communication between doctors and the community would help to spread correct information about the disease and the role that the community can play in controlling the spread of the disease.

    2011-01-01

    Full Text Available Abstract Background Vaccination is one of the cornerstones of controlling an influenza pandemic. To optimise vaccination rates in the general population, ways of identifying determinants that influence decisions to have or not to have a vaccination need to be understood. Therefore, this study aimed to predict intention to have a swine influenza vaccination in an adult population in the UK. An extension of the Theory of Planned Behaviour provided the theoretical framework for the study. Methods Three hundred and sixty two adults from the UK, who were not in vaccination priority groups, completed either an online (n = 306 or pen and paper (n = 56 questionnaire. Data were collected from 30th October 2009, just after swine flu vaccination became available in the UK, and concluded on 31st December 2009. The main outcome of interest was future swine flu vaccination intentions. Results The extended Theory of Planned Behaviour predicted 60% of adults' intention to have a swine flu vaccination with attitude, subjective norm, perceived control, anticipating feelings of regret (the impact of missing a vaccination opportunity, intention to have a seasonal vaccine this year, one perceived barrier: "I cannot be bothered to get a swine flu vaccination" and two perceived benefits: "vaccination decreases my chance of getting swine flu or its complications" and "if I get vaccinated for swine flu, I will decrease the frequency of having to consult my doctor," being significant predictors of intention. Black British were less likely to intend to have a vaccination compared to Asian or White respondents. Conclusions Theoretical frameworks which identify determinants that influence decisions to have a pandemic influenza vaccination are useful. The implications of this research are discussed with a view to maximising any future pandemic influenza vaccination uptake using theoretically-driven applications.

    Full Text Available Swine flu has been confirmed in a number of countries and it is spreading from human to human, which could lead to what is referred to as a pandemic flu outbreak. Pandemic flu is different from ordinary flu because it’s a new flu virus that appears in humans and spreads very quickly from person to person worldwide. The World Health Organization (WHO is closely monitoring cases of swine flu globally to see whether this virus develops into a pandemic. Because it’s a new virus, no one will have immunity to it and everyone could be at risk of catching it. This includes healthy adults as well as older people, young children and those with existing medical conditions. Tamiflu (Oseltamivir and Ralenza (Zanamivir can treat the H1 N1 swine flu strain.

    2008-04-01

    Full Text Available With the threat of an avian flu pandemic once again looming over eastern India, issues regarding patents and affordability and accessibility of drugs have taken center stage. The key priority of India should be to remain prepared to address the public health crisis effectively, by stockpiling the drug tamiflu so that it can be easily distributed and administered to the needy.India had been confronted with a serious threat of avian flu in 2005-06, but past experience shows that, despite having some of the broadest and most comprehensive compulsory patent licensing laws, India's policymaking elite shied away from fully exploiting these legal 'flexibilities.' Fortunately, the danger of avian flu did not turn into a substantial public health crisis that year. Under this backdrop, this paper explores various ‘flexibilities’ available in the Indian patent law and suggests short term and long term strategies to effectively tackle the impending danger of an avian flu pandemic, and similar public health crises in future. This paper will discuss potential areas of conflict between the indigenous generic drug firms and the multi-national companies with respect to TRIPS compliance in the event that these flexibilities are exploited. This paper also highlights the administrative constraints and the economic viability of the compulsory licensing system. Finally, this paper shows how political will is often more critical than having well documented provisions in statute books to respond to such situations effectively.

    While extensive risk perception research has focused on emotions, cognitions, and behavior at static points in time, less attention has been paid to how these variables might change over time. This study assesses how negative affect, threat beliefs, perceived risk, and intended avoidance behavior change over the course of an escalating biological disaster. A scenario simulation methodology was used that presents respondents with a video simulation of a 15-day series of local news reports to immerse respondents in the developing details of the disaster. Systemic manipulation of the virus's causal origin (terrorist attack, medical lab accident, unknown) and the respondent's proximity to the virus (local vs. opposite coast) allowed us to investigate the dynamics of public response. The unfolding scenario was presented in discrete episodes, allowing responses to be tracked over the episodes. The sample includes 600 respondents equally split by sex and by location, with half in the Washington, DC area, and half in the Los Angeles area. The results showed respondents' reactions to the flu epidemic increased as the disaster escalated. More importantly, there was considerable consistency across respondents' emotional, cognitive, and behavioral responses to the epidemic over the episodes. In addition, the reactions of respondents proximally closer to the epidemic increased more rapidly and with greater intensity than their distant counterparts. Finally, as the flu epidemic escalated, both terrorist and accidental flu releases were perceived as being less risky and were less likely to lead to avoidance behavior compared to the unknown flu release.

    2014-01-01

    Background Social media platforms encourage people to share diverse aspects of their daily life. Among these, shared health related information might be used to infer health status and incidence rates for specific conditions or symptoms. In this work, we present an infodemiology study that evaluates the use of Twitter messages and search engine query logs to estimate and predict the incidence rate of influenza like illness in Portugal. Results Based on a manually classified dataset of 2704 tweets from Portugal, we selected a set of 650 textual features to train a Naïve Bayes classifier to identify tweets mentioning flu or flu-like illness or symptoms. We obtained a precision of 0.78 and an F-measure of 0.83, based on cross validation over the complete annotated set. Furthermore, we trained a multiple linear regression model to estimate the health-monitoring data from the Influenzanet project, using as predictors the relative frequencies obtained from the tweet classification results and from query logs, and achieved a correlation ratio of 0.89 (p < 0.001). These classification and regression models were also applied to estimate the flu incidence in the following flu season, achieving a correlation of 0.72. Conclusions Previous studies addressing the estimation of disease incidence based on user-generated content have mostly focused on the english language. Our results further validate those studies and show that by changing the initial steps of data preprocessing and feature extraction and selection, the proposed approaches can be adapted to other languages. Additionally, we investigated whether the predictive model created can be applied to data from the subsequent flu season. In this case, although the prediction result was good, an initial phase to adapt the regression model could be necessary to achieve more robust results. PMID:25077431

    Due to the grave public health implications and economic impact possible with the emergence of the highly pathogenic avian influenza A isolate, H5N1, currently circulating in Asia we have evaluated the efficacy of various disinfectant chemistries against surrogate influenza A strains. Chemistries included in the tests were household bleach, ethanol, Virkon S{reg_sign}, and a modified version of the Sandia National Laboratories developed DF-200 (DF-200d, a diluted version of the standard DF-200 formulation). Validation efforts followed EPA guidelines for evaluating chemical disinfectants against viruses. The efficacy of the various chemistries was determined by infectivity, quantitative RNA, and qualitative protein assays. Additionally, organic challenges using combined poultry feces and litter material were included in the experiments to simulate environments in which decontamination and remediation will likely occur. In all assays, 10% bleach and Sandia DF-200d were the most efficacious treatments against two influenza A isolates (mammalian and avian) as they provided the most rapid and complete inactivation of influenza A viruses.

    Limited research has examined the messages produced about health-related crises on social media platforms and whether these messages contain content that would allow individuals to make sense of a crisis and respond effectively. This study uses the crisis and emergency risk communication (CERC) framework to evaluate the content of messages sent via Twitter during an emerging crisis. Using manual and computer-driven content analysis methods, the study analyzed 25,598 tweets about the H7N9 virus that were produced in April 2013. The study found that a large proportion of messages contained sensemaking information. However, few tweets contained efficacy information that would help individuals respond to the crisis appropriately. Implications and recommendations for practice and future study are discussed.

    When cumulative numbers of patients (X) and deaths (Y) associated with an influenza epidemic are plotted using the log-log scale, the plots fall on an ascending straight line generally expressed as logY = k(logX - logN0). For the 2009 H1N1 influenza pandemic, the slope k was ~0.6 for Mexico and ~2 for other countries. The two-population model was proposed to explain this phenomenon (Yoshikura H. Jpn J Infect Dis. 2012;65:279-88; Yoshikura H. Jpn J Infect Dis. 2009;62:411-2; and Yoshikura H. Jpn J Infect Dis. 2009;62:482-4). The current article reviews and analyzes previous influenza epidemics in Japan to examine whether the two-population model is applicable to them. The slope k was found to be ~2 for the Spanish flu during 1918-1920 and the Asian flu during 1957-1958, and ~1 for the Hong Kong flu and seasonal influenza prior to 1960-1961; however, k was ~0.6 for seasonal influenza after 1960-1961. This transition of the slope k of seasonal influenza plots from ~1 to ~0.6 corresponded to the shift in influenza mortality toward the older age groups and a drastic reduction in infant mortality rates due to improvements in the standard of living during the 1950s and 1960s. All the above observations could be well explained by reconstitution of the influenza epidemic based on the two-population model. PMID:25056069

    Tucker, S P; Cox, C; Steaffens, J

    2001-01-01

    ThermoBioStar's and Biota's flu optical immunoassay (FLU OIA) is a rapid test designed to diagnose influenza A and B infection using a variety of specimen types. The assay uses highly sensitive thin-film detection methods, coupled with specific monoclonal antibodies to the nucleoprotein. The test is simple to perform, requires no instrumentation and is intended to provide a result within 15 min of test initiation in the 'point-of-care' environment. In initial clinical studies, the assay was demonstrated to be equivalent to culture in identifying infected individuals. Subsequent independent studies using a variety of sample types have demonstrated sensitivity ranging from 48 to 100% and specificities ranging from 93 to 97%. In addition to detecting human strains, this assay has been demonstrated to be capable of detecting a variety of avian and non-human mammalian influenza viruses. The FLU OIA test has been used in large-scale surveillance schemes intended to provide rapid epidemiological data during normal influenza seasons and has demonstrated the potential for fulfilling a similar role for multispecies surveillance in, for example, conditions that offer challenges for conventional virus isolation methods. Conceivably, such use should facilitate the timely recognition of influenza outbreaks and prioritization of positive specimens for more conventional, laboratory characterization, leading to improved interpandemic surveillance and rapid reaction in the face of the next pandemic.

    The evolution of the ratite birds has been widely attributed to vicariant speciation, driven by the Cretaceous breakup of the supercontinent Gondwana. The early isolation of Africa and Madagascar implies that the ostrich and extinct Madagascan elephant birds (Aepyornithidae) should be the oldest ratite lineages. We sequenced the mitochondrial genomes of two elephant birds and performed phylogenetic analyses, which revealed that these birds are the closest relatives of the New Zealand kiwi and are distant from the basal ratite lineage of ostriches. This unexpected result strongly contradicts continental vicariance and instead supports flighted dispersal in all major ratite lineages. We suggest that convergence toward gigantism and flightlessness was facilitated by early Tertiary expansion into the diurnal herbivory niche after the extinction of the dinosaurs. PMID:24855267

Swine flu may change the course of many chronic diseases. Thus, all physicians in different disciplines should realize and consider the impact of the current pandemic on their daily practice.As the new pandemic flu virus 2009 (H1N1 has been circulating only in the past nine months, there is still not much evidence on the interaction of this pandemic with chronic diseases.

    Full Text Available Abstract Background The outbreak of the pandemic flu, Influenza A H1N1 (Swine Flu in early 2009, provided a major challenge to health services around the world. Previous pandemics have led to stockpiling of goods, the victimisation of particular population groups, and the cancellation of travel and the boycotting of particular foods (e.g. pork. We examined initial behavioural and attitudinal responses towards Influenza A, H1N1 ("Swine flu" in the six days following the WHO pandemic alert level 5, and regional differences in these responses. Methods 328 respondents completed a cross-sectional Internet or paper-based questionnaire study in Malaysia (N = 180 or Europe (N = 148. Measures assessed changes in transport usage, purchase of preparatory goods for a pandemic, perceived risk groups, indicators of anxiety, assessed estimated mortality rates for seasonal flu, effectiveness of seasonal flu vaccination, and changes in pork consumption Results 26% of the respondents were 'very concerned' about being a flu victim (42% Malaysians, 5% Europeans, p Conclusion Initial responses to Influenza A show large regional differences in anxiety, with Malaysians more anxious and more likely to reduce travel and to buy masks and food. Discussions with family and friends may reinforce existing anxiety levels. Particular groups (homosexuals, prostitutes, the homeless are perceived as at greater risk, potentially leading to increased prejudice during a pandemic. Europeans underestimated mortality of seasonal flu, and require more information about the protection given by seasonal flu inoculation.

    The tetratricopeptide repeat (TPR)-containing protein FLU is a negative regulator of chlorophyll biosynthesis in plants. It directly interacts through its TPR domain with glutamyl-tRNA reductase (GluTR), the rate-limiting enzyme in the formation of δ-aminolevulinic acid (ALA). Delineation of how FLU binds to GluTR is important for understanding the molecular basis for FLU-mediated repression of synthesis of ALA, the universal tetrapyrrole precursor. Here, we characterize the FLU-GluTR interaction by solving the crystal structures of the uncomplexed TPR domain of FLU (FLU(TPR)) at 1.45-Å resolution and the complex of the dimeric domain of GluTR bound to FLU(TPR) at 2.4-Å resolution. Three non-canonical TPR motifs of each FLU(TPR) form a concave surface and clamp the helix bundle in the C-terminal dimeric domain of GluTR. We demonstrate that a 2:2 FLU(TPR)-GluTR complex is the functional unit for FLU-mediated GluTR regulation and suggest that the formation of the FLU-GluTR complex prevents glutamyl-tRNA, the GluTR substrate, from binding with this enzyme. These results also provide insights into the spatial regulation of ALA synthesis by the membrane-located FLU protein.

    Homologous synteny blocks (HSBs) and evolutionary breakpoint regions (EBRs) in mammalian chromosomes are enriched for distinct DNA features, contributing to distinct phenotypes. To reveal HSB and EBR roles in avian evolution, we performed a sequence-based comparison of 21 avian and 5 outgroup species using recently sequenced genomes across the avian family tree and a newly-developed algorithm. We identified EBRs and HSBs in ancestral bird, archosaurian (bird, crocodile, and dinosaur), and reptile chromosomes. Genes involved in the regulation of gene expression and biosynthetic processes were preferably located in HSBs, including for example, avian-specific HSBs enriched for genes involved in limb development. Within birds, some lineage-specific EBRs rearranged genes were related to distinct phenotypes, such as forebrain development in parrots. Our findings provide novel evolutionary insights into genome evolution in birds, particularly on how chromosome rearrangements likely contributed to the formation of novel phenotypes. PMID:27401172

    2015-05-01

    Full Text Available Poultry meat represents one of the most dynamic branches of the local meat production. The poultry sector represents a good quality protein source, at an acceptable price as compared to other animal production domains. There has been an ascending evolution of the sector after the year 2000, although there appeared a series of discontinuities that affected agricultural production, mainly on a short-term basis. The Avian Flu led to 190 million euros’ worth losses at the level of Romanian national economy. Low consumption due to the impact was a short-term consequence, being rapidly amortized by the Romanian producers. The lack of some business continuity insurance measures can further affect the poultry meat sector, which does not have the necessary robustness needed in case of larger shocks. The following article proposes an analysis of the Avian Flu crisis economic effects on the Romanian meat sector, and it is part of a general framework of research regarding the Romanian food chain resilience to critical situations.

  18. Modeling influenza epidemics and pandemics: insights into the future of swine flu (H1N1

    Full Text Available Abstract Here we present a review of the literature of influenza modeling studies, and discuss how these models can provide insights into the future of the currently circulating novel strain of influenza A (H1N1, formerly known as swine flu. We discuss how the feasibility of controlling an epidemic critically depends on the value of the Basic Reproduction Number (R0. The R0 for novel influenza A (H1N1 has recently been estimated to be between 1.4 and 1.6. This value is below values of R0 estimated for the 1918–1919 pandemic strain (mean R0~2: range 1.4 to 2.8 and is comparable to R0 values estimated for seasonal strains of influenza (mean R0 1.3: range 0.9 to 2.1. By reviewing results from previous modeling studies we conclude it is theoretically possible that a pandemic of H1N1 could be contained. However it may not be feasible, even in resource-rich countries, to achieve the necessary levels of vaccination and treatment for control. As a recent modeling study has shown, a global cooperative strategy will be essential in order to control a pandemic. This strategy will require resource-rich countries to share their vaccines and antivirals with resource-constrained and resource-poor countries. We conclude our review by discussing the necessity of developing new biologically complex models. We suggest that these models should simultaneously track the transmission dynamics of multiple strains of influenza in bird, pig and human populations. Such models could be critical for identifying effective new interventions, and informing pandemic preparedness planning. Finally, we show that by modeling cross-species transmission it may be possible to predict the emergence of pandemic strains of influenza.

    Many national organizations call for medical students to receive more public health education in medical school. Nonetheless, limited evidence exists about successful servicelearning programs that administer preventive health services in nonclinical settings. The Flu Crew program, started in 2001 at the Stanford University School of Medicine, provides preclinical medical students with opportunities to administer influenza immunizations in the local community. Medical students consider Flu Crew to be an important part of their medical education that cannot be learned in the classroom. Through delivering vaccines to where people live, eat, work, and pray, Flu Crew teaches medical students about patient care, preventive medicine, and population health needs. Additionally, Flu Crew allows students to work with several partners in the community in order to understand how various stakeholders improve the delivery of population health services. Flu Crew teaches students how to address common vaccination myths and provides insights into implementing public health interventions. This article describes the Stanford Flu Crew curriculum, outlines the planning needed to organize immunization events, shares findings from medical students' attitudes about population health, highlights the program's outcomes, and summarizes the lessons learned. This article suggests that Flu Crew is an example of one viable service-learning modality that supports influenza vaccinations in nonclinical settings while simultaneously benefiting future clinicians.

    2014-01-01

    This article examines flu vaccination beliefs and practices produced during a survey of undergraduate students in Spring 2012 (IRB#10-732). This research uses the methods of rhetorical analysis — or the study of persuasive features and arguments used in language — to examine statements respondents made regarding flu and flu vaccine. In these responses, students generated unique categories of arguments about the perceived dangers of flu vaccination, including the assertion that vaccines cause disease (including illnesses and conditions other than flu), that vaccines are toxic medicines, and that vaccines carry unknown, population-wide risks that are inadequately acknowledged. This study provides insight into vaccination beliefs and rationales among a population at risk of flu (college students) and suggests that further study of this population may yield important keys to addressing flu vaccine concerns as expressed by college students. Rhetorical analysis also offers a useful set of methods to understanding vaccination beliefs and practices, adding to existing methods of study and analysis of vaccination practices and beliefs in medicine and public health.

  3. Christmas Island birds returning

    Science.gov (United States)

    Six months after their mass exodus, birds are beginning to return to Christmas Island. Roughly 17 million birds, almost the entire adult bird population, either perished or fled their mid-Pacific atoll home last autumn, leaving behind thousands of nestlings to starve (Eos, April 5, 1983, p. 131). It is believed that the strong El Niño altered the ecology of the surrounding waters and forced the birds to flee. Christmas Island is the world's largest coral atoll.“Ocean and atmosphere scientists are unsure of future directions for the El Niño conditions and cannot now predict what will happen to the birds in the coming months,” said Ralph W. Schreiber, curator of ornithology at the Natural History Museum of Los Angeles County in California. Heisthe ornithologist who discovered the disappearance. “The recovery of the bird populations depends on the food supply in the waters surrounding the island.” The island's birds feed exclusively on small fish and squid.

    Birds utilize several distinct sensory systems in a flexible manner in their navigation. When navigating with the help of landmarks, location of the sun and stars, or polarization image of the dome of the sky, they resort to vision. The significance of olfaction in long-range navigation has been under debate, even though its significance in local orientation is well documented. The hearing in birds extends to the infrasound region. It has been assumed that they are able to hear the infrasounds generated in the mountains and seaside and navigate by using them. Of the senses of birds, the most exotic one is the ability to sense magnetic fields of the earth.

    This study examined how major TV news networks covered two flu pandemics in 1976 and 2009 in terms of news frames, mortality exemplars, mortality subject attributes, vaccination, evaluation approaches, and news sources. Results showed that the first pandemic was frequently framed with the medical/scientific and political/legal issues, while the second pandemic was emphasized with the health risk issue in TV news. Both flu pandemics were regularly reported with mortality exemplars, but the focus in the first pandemic was on the flu virus threat and vaccination side effects, while the vaccination shortage was frequently revealed in the second outbreak.

    The use of birds as indicators for 'biological qualities' is not without risks, and should always be based on a sound knowledge of population dynamics and ecological requirements of the species involved. Meadow birds form a comparatively well-studied group of waders, which breed in Dutch grasslands, heavily influenced by agricultural management. The individual species show different tolerances to intensity levels of management, and can therefore be used as indicators for these levels. PMID:24259105

    Vertebrate MOXD2 encodes a monooxygenase DBH-like 2 protein that could be involved in neurotransmitter metabolism, potentially during olfactory transduction. Loss of MOXD2 in apes and whales has been proposed to be associated with evolution of olfaction in these clades. We analyzed 57 bird genomes to identify MOXD2 sequences and found frequent loss of MOXD2 in 38 birds. Among the 57 birds, 19 species appeared to have an intact MOXD2 that encoded a full-length protein; 32 birds had a gene with open reading frame-disrupting point mutations and/or exon deletions; and the remaining 6 species did not show any MOXD2 sequence, suggesting a whole-gene deletion. Notably, among 10 passerine birds examined, 9 species shared a common genomic deletion that spanned several exons, implying the gene loss occurred in a common ancestor of these birds. However, 2 closely related penguin species, each of which had an inactive MOXD2, did not share any mutation, suggesting an independent loss after their divergence. Distribution of the 38 birds without an intact MOXD2 in the bird phylogenetic tree clearly indicates that MOXD2 loss is widespread and independent in bird lineages. We propose that widespread MOXD2 loss in some bird lineages may be implicated in the evolution of olfactory perception in these birds. PMID:27074048

This study aimed at analyzing whether this common etiology also result in significant correlations of clinical manifestations. To do so, data were collected to compare the clinical evolution of cases in the 1918 and 2009 epidemics.  This historical revision was the ground for evaluating the response to treatment including homeopathy in the former epidemics. It is discussed the convenience of including homeopathic prophylaxis grounded on the diagnosis of the epidemic genius among public health actions.

    2010-01-01

    For a given, arbitrary graph, what is the epidemic threshold? That is, under what conditions will a virus result in an epidemic? We provide the super-model theorem, which generalizes older results in two important, orthogonal dimensions. The theorem shows that (a) for a wide range of virus propagation models (VPM) that include all virus propagation models in standard literature (say, [8][5]), and (b) for any contact graph, the answer always depends on the first eigenvalue of the connectivity matrix. We give the proof of the theorem, arithmetic examples for popular VPMs, like flu (SIS), mumps (SIR), SIRS and more. We also show the implications of our discovery: easy (although sometimes counter-intuitive) answers to `what-if' questions; easier design and evaluation of immunization policies, and significantly faster agent-based simulations.

    The Fiber Linked Unit for Optical Recombination (FLUOR) is a precision interferometric beam combiner operating at the CHARA Array on Mt. Wilson, CA. It has recently been upgraded as part of a mission known as "Jouvence of FLUOR" or JouFLU. As part of this program JouFLU has new mechanic stages and optical payloads, new alignment systems, and new command/control software. Furthermore, new capabilities have been implemented such as a Fourier Transform Spectrograph (FTS) mode and spectral dispersion mode. These upgrades provide new capabilities to JouFLU as well as improving statistical precision and increasing observing efficiency. With these new systems, measurements of interferometric visibility to the level of 0.1% precision are expected on targets as faint as 6th magnitude in the K band. Here we detail the upgrades of JouFLU and report on its current status.

An effective prospective data resource exists in the United Kingdom (UK that could have been utilized to describe the scope and extent of the swine flu outbreak as it unfolded. We describe the 2009 swine flu outbreak in the UK as recorded daily by general practitioners and the potential use of this database for real-time tracking of flu outbreaks. Methods. Using the General Practice Research Database, a real-time general practice, electronic database, we estimated influenza incidence from July 1998 to September 2009 according to age, region, and calendar time. Results. From 1998 to2008, influenza outbreaks regularly occurred yearly from October to March, but did not typically occur from April to September until the swine flu outbreak began in April 2009. The weekly incidence rose gradually, peaking at the end of July, and the outbreak had largely dissipated by early September. Conclusions. The UK swine flu outbreak, recorded in real time by a large group of general practitioners, was mild and limited in time. Simultaneous online access seemed feasible and could have provided additional clinical-based evidence at an early planning stage of the outbreak.

    This study looks at public awareness and understanding of the Spanish flu in the United States between June 1918, when the flu became "Spanish," and the end of September when the deadly second wave reached the majority of the country. Based on an extensive reading of local newspapers, it finds a near universal lack of preparation or panic or other signs of personal concern among those in the unaffected areas, despite extensive and potentially worrying coverage of the flu's progress. The normal reaction to news of the inexorable approach of a pandemic of uncertain virulence is anxiety and action. The Spanish flu produced neither in the uninfected areas for a month. The most likely reason appears to be cognitive inertia-the tendency of existing beliefs or habits of thought to blind people to changed realities. This inertia grew out of the widespread understanding of flu as a seasonal visitor that while frequently unpleasant almost never killed the strong and otherwise healthy. This view of the flu was powerful enough that it blinded many in the unaffected regions to the threat for weeks even in the face of daily or near daily coverage of the pandemic's spread.

    Full Text Available Siddha medicine is one of the oldest medical systems in the world. This system is most commonly practicing in India especially in southern regions. Siddha medicines become popular nowadays because of various outbreaks of communicable and very infectious diseases like chikungunya, dengue, swine flu etc. These diseases of viral origin are very challenge to the modern world because of lack of ideal anti-viral therapy. Pandemic flu is different from ordinary flu because it’s a new flu virus that appears in humans and spreads very quickly from person to person worldwide. Because it’s a new virus, no one will have immunity to it and everyone could be at risk of catching it. This includes healthy adults as well as older people, young children and those with existing medical conditions. The polyherbal decoction Kapa Sura Kudineer (KSK is a well-known one in this series next to Nilavembu kudineer (NVK. This KSK is introduced for the prevention and the management of Swine flu. And the people of Tamil Nadu are very attentive about this Siddha drug KSK because to prevent and protect from the deadly life threatening disease, Swine flu. Here, an attempt has been made to review the explored ethno pharmacological activities of the ingredients of KSK to strengthen the scientific facts favoring this formulation.

    Full Text Available Drug-induced flu-like syndrome is very rare. It is mainly produced by rifampicin. We report a case of pulmonary tuberculosis (PTB that developed isoniazid-induced flu-like syndrome, but could be cured with a modified regimen replacing isoniazid with levofloxacin. A 10-year-old girl with PTB was treated with isoniazid (H, rifampicin (R, ethambutol (E, and pyrazinamide (Z. She developed features of flu from the sixth day. Symptoms recurred everyday within 1 h of drug ingestion and subsided automatically by next 12 h. After admission, HREZ were continued. She developed symptoms of flu after 1 h of drug ingestion. Antitubercular therapy (ATT was stopped and symptoms subsided automatically. Individual drug was started one by one after three days. Severe symptoms of flu developed after taking isoniazid, while other drugs were tolerated well. Levofloxacin was used as an alternative to isoniazid. She was cured after 6 months of chemotherapy. Isoniazid can possibly cause flu-like syndrome and the treating physician should be aware of this possible side effect when using ATT.

    In this paper, we revisit the dynamical interaction among prey (bird), mesopredator (rat), and superpredator (cat) discussed in [Courchamp, F., Langlais, M., Sugihara, G., 1999. Cats protecting birds: modelling the mesopredator release effect. Journal of Animal Ecology 68, 282-292]. First, we develop a prey-mesopredator-superpredator (i.e., bird-rat-cat, briefly, BRC) model, where the predator's functional responses are derived based on the classical Holling's time budget arguments. Our BRC model overcomes several model construction problems in Courchamp et al. (1999), and admits richer, reasonable and realistic dynamics. We explore the possible control strategies to save or restore the bird by controlling or eliminating the rat or the cat when the bird is endangered. We establish the existence of two types of mesopredator release phenomena: severe mesopredator release, where once superpredators are suppressed, a burst of mesopredators follows which leads their shared prey to extinction; and mild mesopredator release, where the mesopredator release could assert more negative impact on the endemic prey but does not lead the endemic prey to extinction. A sharp sufficient criterion is established for the occurrence of severe mesopredator release. We also show that, in a prey-mesopredator-superpredator trophic food web, eradication of introduced superpredators such as feral domestic cats in the BRC model, is not always the best solution to protect endemic insular prey. The presence of a superpredator may have a beneficial effect in such systems. PMID:15998496

    2014-05-01

    Wild birds have been postulated as sentinels, reservoirs, and potential spreaders of antibiotic resistance. Antibiotic-resistant bacteria have been isolated from a multitude of wild bird species. Several studies strongly indicate transmission of resistant bacteria from human rest products to wild birds. There is evidence suggesting that wild birds can spread resistant bacteria through migration and that resistant bacteria can be transmitted from birds to humans and vice versa. Through further studies of the spatial and temporal distribution of resistant bacteria in wild birds, we can better assess their role and thereby help to mitigate the increasing global problem of antibiotic resistance.

    Birds utilize several distinct sensory systems in a flexible manner in their navigation. When navigating with the help of landmarks, location of the sun and stars, or polarization image of the dome of the sky, they resort to vision. The significance of olfaction in long-range navigation has been under debate, even though its significance in local orientation is well documented. The hearing in birds extends to the infrasound region. It has been assumed that they are able to hear the infrasounds generated in the mountains and seaside and navigate by using them. Of the senses of birds, the most exotic one is the ability to sense magnetic fields of the earth. PMID:27522832

    Siniscalchi, Alan; Schulte, Amanda

    2013-01-01

    Objective This project was organized to facilitate discussions on whether successful novel flu surveillance can be conducted by jurisdictions with limited resources. The discussions will focus on gathering opinions regarding the best combination of surveillance systems to quickly and efficiently identify the presence of influenza A (H3N2)v and other novel influenza viruses in circulation. Introduction The past decade has witnessed rapid development and implementation of numerous syndromic and other advanced surveillance systems to supplement traditional laboratory testing to identify the presence of novel influenza strains and track the impact on local populations. While much of the development and widespread implementation of these systems had been supported by public health preparedness funding, the loss of these monies has greatly constrained the ability of public health agencies to staff and maintain these systems. The periodic appearance of novel flu viruses, such as H3N2v, requires agencies to carefully choose which systems will provide the most cost-effective data to support their public health practice. Methods This project will be facilitated by an experienced public health practitioner who has conducted surveillance for a variety of disease agents. Additional public health practitioners are being recruited among members of the International Society for Disease Surveillance (ISDS) Public Health Practice Committee (PHPC) to contribute information on comparative approaches to cost effective surveillance. Questions were selected for discussion and responses will be collected from influenza surveillance coordinators using a web-based survey tool managed by ISDS staff on behalf of the PHPC. Survey responses and subsequent recommendations will be presented at a PHPC meeting. Results Initial questions selected for the survey tool and subsequent discussions include: What surveillance systems does your agency use for conducting influenza surveillance? Which

    Full Text Available Abstract Background The first cases of influenza A/H1N1 (swine flu were confirmed in the UK on 27th April 2009, after a novel virus first identified in Mexico rapidly evolved into a pandemic. The swine flu outbreak was the first pandemic in more than 40 years and for many, their first encounter with a major influenza outbreak. This study examines public understandings of the pandemic, exploring how people deciphered the threat and perceived they could control the risks. Methods Purposive sampling was used to recruit seventy three people (61 women and 12 men to take part in 14 focus group discussions around the time of the second wave in swine flu cases. Results These discussions showed that there was little evidence of the public over-reacting, that people believed the threat of contracting swine flu was inevitable, and that they assessed their own self-efficacy for protecting against it to be low. Respondents assessed a greater risk to their health from the vaccine than from the disease. Such findings could have led to apathy about following the UK Governments recommended health protective behaviours, and a sub-optimal level of vaccine uptake. More generally, people were confused about the difference between seasonal influenza and swine flu and their vaccines. Conclusions This research suggests a gap in public understandings which could hinder attempts to communicate about novel flu viruses in the future. There was general support for the government's handling of the pandemic, although its public awareness campaign was deemed ineffectual as few people changed their current hand hygiene practices. There was less support for the media who were deemed to have over-reported the swine flu pandemic.

  4. The biotherapics Influenzinum and Oscilococcinum in the treatment of influenza virus flu

    Directory of Open Access Journals (Sweden)

    Camila Monteiro Siqueira

    2011-07-01

    Full Text Available Introduction: The influenza virus flu is a widespread illness which is responsible for hundreds of thousands of deaths annually. About 20% of children and 5% of adults are infected with this virus every year. The disease is highly contagious and its transmission occurs by saliva particles of the infected person, expelled by breathing, talking and coughing [1]. Flu pandemics are generally caused by the appearance of a new subtype of the virus in humans, which occurs as a result of the existing flu in animal species transmitted to humans [2]. Despite the fact there are antiviral drugs, the virus develops mutations, creating resistance to these drugs in few days. Thus, the development of new therapies, including homeopathy, that can prevent and/or treat this disease becomes increasingly necessary. In this scenario, biotherapics appear as drugs that are made from biological products, such as secretions, tissues, organs whose compounding follows the homeopathic pharmacopeia. Objective: This study is a literature review on the treatment of flu with biotherapics used in clinical medicine, namely Influenzinum and Oscilococcinum. Method: Studies on the prescription of biotherapics for the prevention and cure of the flu as well as literature about the history and evolution of Homeopathy were reviewed in the present work. Influenzinum is a biotherapic made from the influenza vaccine from Pasteur Laboratory, while Oscillococcinum is obtained from the lysate of the liver and heart of the goose Anas barbaries. Results: Preliminary results showed that both medicines are widely used in clinical medicine. Influenzinum 9CH is prescribed for flu prevention and treatment, while Oscilococcinum is more used to reduce the severe symptoms in patients who already have the flu. Conclusion: Based on these results, it is possible to say that Influenzinum has a very important role in the prevention and cure of the influenza and Oscilococcinnum is useful in the relief of the

Nonetheless, limited evidence exists about successful service-learning programs that administer preventive health services in nonclinical settings. The Flu Crew program, started in 2001 at the Stanford University School of Medicine, provides preclinical medical students with opportunities to administer influenza immunizations in the local community. Medical students consider Flu Crew to be an important part of their medical education that cannot be learned in the classroom. Through delivering vaccines to where people live, eat, work, and pray, Flu Crew teaches medical students about patient care, preventive medicine, and population health needs. Additionally, Flu Crew allows students to work with several partners in the community in order to understand how various stakeholders improve the delivery of population health services. Flu Crew teaches students how to address common vaccination myths and provides insights into implementing public health interventions. This article describes the Stanford Flu Crew curriculum, outlines the planning needed to organize immunization events, shares findings from medical students' attitudes about population health, highlights the program’s outcomes, and summarizes the lessons learned. This article suggests that Flu Crew is an example of one viable service-learning modality that supports influenza vaccinations in nonclinical settings while simultaneously benefiting future clinicians.

    Anaesthesia in birds is ordered by law and is also necessary for various operations and manipulations. Anaesthesia by injection of Ketamin, which in special cases may be combined with Diazepam, has been found useful. Anaesthesia by inhalation with Halothan, Methoxyfluran or Isofluran is the most careful method. Local anaesthesia has few indications.

    Neotropical migrants are birds that breed in North America and winter primarily in Central and South America. Long-term population studies of birds in the Eastern United States indicated declines of some forest-dwelling birds, many of which winter in the Neotropics (Peterjohn and others 1995). These declines were attributed to loss of wintering and breeding habitat due to deforestation and fragmentation, respectively. Many species of Nearctic migrants--birds that breed in the northern regions of North America and winter in the Southern United States--are also experiencing population declines. Because large areas of undistrubed, older, bottomland hardwood forests oftern contain large numbers of habitat specialists, including forest-interior neotropical migrants and wintering Nearctic migrants, these forests may be critical in maintaining avian diversity. This study had two primary objectivs: (1) to create a baseline data set that can be used as a standard against which other bottomland hardwood forests can be compared, and (2) to establish long-term monitoring stations during both breeding and wintering seasons to discern population trends of avian species using bottomland hardwood forests.

  11. Nudges or mandates? The ethics of mandatory flu vaccination.

    2015-05-21

    According to the CDC report for the 2012-2013 influenza season, there was a modest increase in the vaccination coverage rate among healthcare workers from 67% in 2011-2012, to 72% in 2012-2013 to the current 75% coverage. This is still far from reaching the US National Healthy People 2020 goal of 90% hospitals vaccination rates. The reported increase in coverage is attributed to the growing number of healthcare facilities with vaccination requirements with average rates of 96.5%. However, a few other public health interventions stir so much controversy and debate as vaccination mandates. The opposition stems from the belief that a mandatory flu shot policy violates an individual right to refuse unwanted treatment. This article outlines the historic push to achieve higher vaccination rates among healthcare professionals and a number of ethical issues arising from attempts to implement vaccination mandates. It then turns to a review of cognitive biases relevant in the context of decisions about influenza vaccination (omission bias, ambiguity aversion, present bias etc.) The article suggests that a successful strategy for policy-makers and others hoping to increase vaccination rates is to design a "choice architecture" that influences behavior of healthcare professionals without foreclosing other options. Nudges incentivize vaccinations and help better align vaccination intentions with near-term actions. PMID:25869886

    2011-07-01

    Full text: Climate change, perhaps more accurately described as climate disruption, is considered to be a major long-term threat to biodiversity, with a high probability that the underlying cause is due to anthropogenic greenhouse gas emissions. Renewable energy is an important component of a programme of measures to combat further climate change, to include improved energy efficiency and demand management. Wind energy is the most advanced renewable energy source and is a global industry onshore and, increasingly, offshore. However, as with any form of energy generation, wind energy also has potential environmental costs which have to be balanced against benefits. The environmental impacts on birds derive from the following: collision risk, in particular from the moving rotor blades; displacement arising from disturbance during construction, operation or decommissioning; habitat loss or change leading to alteration of food availability; barrier effects leading to deviation of long distance migratory flights or disruption of local flights between feeding, nesting, and roosting/loafing locations. Not all species of birds, or individuals within a species, are equally susceptible to negative interactions with wind turbines, and neither are the population consequences of impacts equivalent. Of greatest concern are bird species of conservation concern that exhibit behaviours that place them at risk of an adverse impact, notably when that impact leads to a reduction in population size that is unlikely to be compensated for. In particular, cumulative impacts arising from multiple wind farms or wind farms in combination with other developments are of concern. There has been a welcome increase in research effort and peer-reviewed publications on the subject of birds and wind energy in recent years. Increasing our understanding of impacts is essential to delivering possible solutions and this paper reviews current knowledge for birds. (Author)

  18. The evolutionary genetics and emergence of avian influenza viruses in wild birds.

    2008-05-01

    Full Text Available We surveyed the genetic diversity among avian influenza virus (AIV in wild birds, comprising 167 complete viral genomes from 14 bird species sampled in four locations across the United States. These isolates represented 29 type A influenza virus hemagglutinin (HA and neuraminidase (NA subtype combinations, with up to 26% of isolates showing evidence of mixed subtype infection. Through a phylogenetic analysis of the largest data set of AIV genomes compiled to date, we were able to document a remarkably high rate of genome reassortment, with no clear pattern of gene segment association and occasional inter-hemisphere gene segment migration and reassortment. From this, we propose that AIV in wild birds forms transient "genome constellations," continually reshuffled by reassortment, in contrast to the spread of a limited number of stable genome constellations that characterizes the evolution of mammalian-adapted influenza A viruses.

    Background Influenza A (flu) virus causes significant morbidity and mortality worldwide, and current vaccines require annual updating to protect against the rapidly arising antigenic variations due to antigenic shift and drift. In fact, current subunit or split flu vaccines rely exclusively on antibody responses for protection and do not induce cytotoxic T (Tc) cell responses, which are broadly cross-reactive between virus strains. We have previously reported that γ-ray inactivated flu virus can induce cross-reactive Tc cell responses. Methodology/Principal Finding Here, we report that intranasal administration of purified γ-ray inactivated human influenza A virus preparations (γ-Flu) effectively induces heterotypic and cross-protective immunity. A single intranasal administration of γ-A/PR8[H1N1] protects mice against lethal H5N1 and other heterotypic infections. Conclusions/Significance Intranasal γ-Flu represents a unique approach for a cross-protective vaccine against both seasonal as well as possible future pandemic influenza A virus infections.

We have previously reported that gamma-ray inactivated flu virus can induce cross-reactive Tc cell responses. METHODOLOGY/PRINCIPAL FINDING: Here, we report that intranasal administration of purified gamma-ray inactivated human influenza A virus preparations (gamma-Flu effectively induces heterotypic and cross-protective immunity. A single intranasal administration of gamma-A/PR8[H1N1] protects mice against lethal H5N1 and other heterotypic infections. CONCLUSIONS/SIGNIFICANCE: Intranasal gamma-Flu represents a unique approach for a cross-protective vaccine against both seasonal as well as possible future pandemic influenza A virus infections.

    Exploiting the high sensitivity of the chemiluminescence phenomenon, an accurate and sensitive point-of-care test, called the ZstatFlu-II test (ZymeTx, Inc., Oklahoma City, Okla.), was developed to detect influenza virus infections. The ZstatFlu-II test takes 20 min and requires approximately 2 min of “hands-on” time for operational steps. The ZstatFlu-II test does not distinguish between infections with influenza virus types A and B. ZstatFlu-II test results are printed on Polaroid High-Speed Detector Film, allowing test results to be archived. A prototype version of the ZstatFlu-II test was evaluated during the 2000-to-2001 flu season with 300 nasal aspirate specimens from children at a pediatric hospital. Compared to culture, the ZstatFlu-II test had 88% sensitivity and 92% specificity. The Directigen test had a sensitivity of 75% and a specificity of 93%. The sensitivity of the ZstatFlu-II test was significantly higher than that of the Directigen test (P < 0.0574). PMID:12089243

    Flu pandemics (worldwide epidemics) have occurred at irregular and unpredictable intervals, and have been associated with substantial morbidity, mortality and economic cost. In response to the emerging potential for a new pandemic to occur, national and international preparedness plans are being drawn up specifying the use of antivirals and vaccines. A number of challenges to pandemic vaccine development, large-scale production and the timing of distribution have also been highlighted. This article reviews the rationale and consequential policy for aligned public- and private sector planning in the present inter-pandemic period despite the prevalent risks and uncertainties. We propose a model for product development of pandemic flu vaccine based on public-private partnership, including push and pull incentive mechanisms for stimulating work in this therapeutic area. In addition, we argue that innovative vaccination strategies, together with special vaccine formulations which may offer cross-protection against multiple flu pandemic strains might avert the worse effects of an influenza infection.

    The "Spanish Flu" began in 1918 and was the most devastating pandemic in human history that had ever been, claiming more lives than World War I. The flu virus had not yet been discovered, and the usual therapy measures were merely symptomatic. In many parts of the world the pandemic was treated by homeopaths. At the time, homeopathic medical practices, out-patient clinics and hospitals existed in various countries. To this day homeopaths refer to the successful homeopathic treatment of the "Spanish Flu". The following paper looks at what this treatment consisted in and whether it was based on a particular concept. It also examines contemporary evaluations and figures, as well as the question as to whether homeopathy experienced a rise in demand as a consequence of its success during the pandemic.

The main clinical manifestations of influenza include fever, sore throat, headache, cough, coryza, and malaise. Apart from the well known classical influenza, there are also groups of influenza virus infections that are called “atypical infection”. These infections are usually due to a novel influenza virus infection. In early 2009, an emerging novel influenza originating from Mexico called swine flu was reported. The World Health Organization noted a level VI precaution, the highest level precaution possible, for this newest influenza virus infection. As of June 2009, it is not known if this disease will be successfully controlled. Finding new drugs and vaccine for the emerging swine flu is still required to cope with this emerging worldwide problem.Keywords: swine flu, drug, vaccine, concept

    2016-01-01

    An infectious diseases caused by RNA virus, the influenza is also commonly known as Flu. It mainly transmitted through air by coughs or sneezes of infected. The symptoms of flu like fever and headache are the result of the huge amounts of proinflammatory cytokines and chemokines (such as interferon or tumor necrosis factor) produced from influenza-infected cells. The activated vitamin has extreme effects on human immunity. Vitamin D prevents too much release of cytokines and chemokines. Staying much time indoor, away from contact of sunlight during winter season lowers the vitamin D level in human body. Thus, the chance of getting flu increases in winter season. Formulation of policy regarding vitamin D supplementation in diet for people such as elderly and with low sunlight exposure is hereby recommended. It will be beneficial to reduce influenza related morbidity and mortality during winter season. PMID:27426715

  8. Risky Zoographies: The Limits of Place in Avian Flu Management

    Directory of Open Access Journals (Sweden)

    Natalie Porter

    2012-11-01

    Full Text Available Global anxieties about avian influenza stem from a growing recognition that highly-virulent, highly-mobile disease vectors infiltrate human spaces in ways that are difficult to perceive, and even more difficult to manage. This article analyses a participatory health intervention in Việt Nam to explore how avian influenza threats challenge long-held understandings of animals’ place in the environment and society. In this intervention, poultry farmers collaborated with health workers to illustrate maps of avian flu risks in their communities. Participant-observation of the risk-mapping exercises shows that health workers treated poultry as commodities, and located these animals in environments that could be transformed and dominated by humans. However, these maps did not sufficiently represent the physical and social landscapes where humans and poultry coexist in Việt Nam. As such, farmers located poultry in environments dominated by risky nonhuman forces such as winds, waterways, and other organisms. I argue that these divergent risk maps demonstrate how ecological factors, interpersonal networks, and global market dynamics combine to engender a variety of interspecies relationships, which in turn shape the location of disease risks in space. I develop the term risky zoographies to signal the emergence of competing descriptions of animals and their habitats in zoonotic disease contexts. This concept suggests that as wild animals, livestock products, and microbial pathogens continue to globalise, place-based health interventions that limit animals to particular locales are proving inadequate. Risky zoographies signal the inextricability of nonhuman animals from human spaces, and reveal interspecies interactions that transect and transcend environments.

  9. Controlling pandemic flu: the value of international air travel restrictions.

    Directory of Open Access Journals (Sweden)

    Joshua M Epstein

    Full Text Available BACKGROUND: Planning for a possible influenza pandemic is an extremely high priority, as social and economic effects of an unmitigated pandemic would be devastating. Mathematical models can be used to explore different scenarios and provide insight into potential costs, benefits, and effectiveness of prevention and control strategies under consideration. METHODS AND FINDINGS: A stochastic, equation-based epidemic model is used to study global transmission of pandemic flu, including the effects of travel restrictions and vaccination. Economic costs of intervention are also considered. The distribution of First Passage Times (FPT to the United States and the numbers of infected persons in metropolitan areas worldwide are studied assuming various times and locations of the initial outbreak. International air travel restrictions alone provide a small delay in FPT to the U.S. When other containment measures are applied at the source in conjunction with travel restrictions, delays could be much longer. If in addition, control measures are instituted worldwide, there is a significant reduction in cases worldwide and specifically in the U.S. However, if travel restrictions are not combined with other measures, local epidemic severity may increase, because restriction-induced delays can push local outbreaks into high epidemic season. The per annum cost to the U.S. economy of international and major domestic air passenger travel restrictions is minimal: on the order of 0.8% of Gross National Product. CONCLUSIONS: International air travel restrictions may provide a small but important delay in the spread of a pandemic, especially if other disease control measures are implemented during the afforded time. However, if other measures are not instituted, delays may worsen regional epidemics by pushing the outbreak into high epidemic season. This important interaction between policy and seasonality is only evident with a global-scale model. Since the benefit of

    It is well established, that viral infections may trigger urticaria or allergic asthma; however, as viral infections induce T helper 1 polarized responses, which lead to the inhibition of T helper 2 cell development, the opposite would be plausible. We wanted to investigate how viral infections may mediate allergic symptoms in a mouse model; therefore, we infected BALB/C mice with influenza A virus intranasally. Histologic analyses of lung sections and bronchoalveolar lavages were performed. In addition, cells from the mediastinal lymph nodes were restimulated in vitro to analyze which types of cytokines were induced by the flu infection. Furthermore, flu-specific antibody titers were determined and local anaphylaxis was measured after rechallenge with flu antigen. We found that airways inflammation consisted predominately of macrophages and lymphocytes, whereas only a few eosinophils were observed. interferon-gamma but no interleukin-4 and little interleukin-5 could be detected in the culture supernatants from in vitro restimulated T cells from the draining lymph nodes. The antibody response was characterized by high levels of virus-specific IgG2a, IgG2b, and IgG1 and, surprisingly, low levels of virus-specific IgE antibodies. Interestingly, flu-infected mice developed active and passive cutaneous anaphylaxis after rechallenge with flu-antigen. As the passive cutaneous anaphylaxis reaction persisted over 48 h and was significantly lower after passive transfer of the serum, which was IgE depleted, local anaphylaxis seemed to be mediated predominately by specific IgE antibodies. Taken together, our results demonstrate that mice infected with flu virus develop virus-specific mast cell degranulation in the skin. Our results may also have implications for the pathogenesis of urticaria or other atopic disorders in humans. PMID:11918711

    Acute necrotizing encephalopathy of childhood (ANEC) is a rare condition characterized by the presence of multifocal symmetrical brain lesions involving mainly thalami, brainstem, cerebellum and white matter. ANEC is a serious and life threatening complication of simple viral infections. We present a case of a young child who developed this condition with classical clinical and radiological findings consistent with ANEC, secondary to swine flu (H1N1). He needed ventilatory support and had profound motor and intellectual deficit on discharge. We report this case with aim of raising awareness about this fatal complication of swine flu which has become a global health care issue these days. (author)

We report genome size measurements for 37 species of hummingbirds that confirm this prediction. Our result...

  5. The European and Japanese outbreaks of H5N8 derive from a single source population providing evidence for the dispersal along the long distance bird migratory flyways

    Directory of Open Access Journals (Sweden)

    Andrew R. Dalby

    2015-04-01

    Full Text Available The origin of recent parallel outbreaks of the high pathogenicity H5N8 avian flu virus in Europe and in Japan can be traced to a single source population, which has most likely been spread by migratory birds. By using Bayesian coalescent methods to analyze the DNA sequences of the virus to find the times for divergence and combining this sequence data with bird migration data we can show the most likely locations and migratory pathways involved in the origin of the current outbreak. This population was most likely located in the Siberian summer breeding grounds of long-range migratory birds. These breeding grounds provide a connection between different migratory flyways and explain the current outbreaks in remote locations. By combining genetic methods and epidemiological data we can rapidly identify the sources and the dispersion pathways for novel avian influenza outbreaks.

  8. The North Sea Bird Club

    International Nuclear Information System (INIS)

    This paper reports that the creation of a club for the purpose of encouraging oil and gas workers to watch birds may not at first seem a viable proposition. To the layperson, birds offshore conjures up an image of hundreds of seagulls following fishing boats, and very little else. Also, the act of birdwatching is not seen as a typical offshore worker's activity. Anyone who has worked on an installation offshore and who has any interest in wildlife will be aware of the occasional presence of land-birds. Two decades ago, prompted by some keen offshore workers, a single oil company set up a monitoring program, which quickly became popular with a number of its employees. Birds seem offshore were recorded on data forms and collected together. At this stage the club was purely another recreation facility; however, when the data were collated it was soon realized that installations offshore were being used as staging posts by birds on migration, and that the information being collected would be of great interest in the study of bird movements. All over Britain, at strategic points on the coastline, there are bird observatories which record the arrival and departure of migrating birds. The presence of several hundred solid structures up and down the North Sea, which are used by birds en route, represents a huge, unique bird observatory, capable of uncovering facts about bird migration which have long eluded land-based scientists. Eleven years ago, the North Sea Bird Club began, composed of eight member companies, a recorder from Aberdeen University and a representative from the Nature Conservancy Council. The club received data from 41 installations, and the recorder collated these on Aberdeen University's computer and produced an annual report of sightings

In view of the recent pandemic, it would be interesting to review the neuropsychiatric aspects of influenza, specifically swine flu. Author used popular search engine ′PUBMED′ to search for published articles with different MeSH terms using Boolean operator (AND. Among these, a selective review of the published literature was done. Acute manifestations of swine flu varied from behavioral changes, fear of misdiagnosis during outbreak, neurological features like seizures, encephalopathy, encephalitis, transverse myelitis, aseptic meningitis, multiple sclerosis, and Guillian-Barre Syndrome. Among the chronic manifestations, schizophrenia, Parkinson′s disease, mood disorder, dementia, and mental retardation have been hypothesized. Further research is required to understand the etiological hypothesis of the chronic manifestations of influenza. The author urges neuroscientists around the world to make use of the current swine flu pandemic as an opportunity for further research.

  3. 108 Development of universal vaccines against flu: reality and prospects

    Science.gov (United States)

    Shmarov, M.M.

    2014-01-01

    Two surface glycoproteins hemagglutinin and neuraminidase are the main antigens for obtaining traditional flu vaccines due to their high immunogenicity and ability to induce generation of neutralizing antibodies. High genetically instability of influenza virus provides antigenic diversity of these glycoproteins between strains. Subunit vaccines based on one of these surface antigens are characterized by narrow specificity. Modern vaccines should provide protection against several or all subtypes of influenza A viruses. In addition sporadic influenza outbreaks of newly emerged influenza A viruses may cause the next pandemic. Today there are no flu vaccines of a wide range of action, so-called “universal” vaccines. Several flu vaccines with a broad cross-protectivity are tested in different phases of clinical trials. In this report the analysis of the modern researches directed on creation of flu “universal” vaccines including data obtained by researchers of Gamaleya institute of epidemiology and microbiology is carried out. Genetic immunization technology is used for development of “universal” vaccine. Recombinant pseudoadenoviral particles coding of influenza virus conservative antigens were used as a vector for gene delivery. Polypeptide, containing hemagglutinin conservative epitopes, was used in addition to traditional influenza conservative antigens M1, M2 and NP. Animal experiments demonstrated that developed vaccines were very efficient against different influenza subtypes (80%–100% survivability).

    Full Text Available Flu monitoring was carried out in children’s general hospital in St. Petersburg within three epidemic seasons (2010–2011, 2011–2012 and 2012–2013. 1916 patients under the age of 18 years were examined with the complex of virologic tests . The natural decreasing of flu incidence and predominant diagnosing in etiologic structure one of the virus serotypes [in the first A(H1N1pdm09, in the second — A(H3N2] have been observed during the first two years after a pandemic. In the third season restoration of the main characteristics of epidemic flu situation were detected: polietiology with annual change of serotypes proportions, late start (winter and spring, majority of younger children among hospitalaized patients and a mild course of disease. The most probable candidates [viruses of a subtype A(H3N2] are revealed as a causal factor of significant increasing of disease incidence with the severe forms in the near future. Laboratory data were confirmed by increase in frequency of the complicated by pneumonia ARI at hospitalized patients during the periods of their maximum registration. All isolates received during the study were corresponded to the referens-strains included in vaccines. Thus, timely and appropriate vaccination during the studied period had to become an effective protection against a flu.

    2010-08-01

    A bird species is regarded as alien invasive if it has been introduced, intentionally or accidentally, to a location where it did not previously occur naturally, becomes capable of establishing a breeding population without further intervention by humans, spreads and becomes a pest affecting the environment, the local biodiversity, the economy and/or society, including human health. European Starling (Sturnus vulgaris), Common Myna (Acridotheres tristis) and Red-vented Bulbul (Pycnonotus cafer) have been included on the list of '100 of the World's Worst Invasive Alien Species', a subset of the Global Invasive Species Database. The 'Delivering Alien Invasive Species Inventories for Europe' project has selected Canada Goose (Branta canadensis), Ruddy Duck (Oxyura jamaicensis), Rose-ringed Parakeet (Psittacula krameri) and Sacred Ibis (Threskiornis aethiopicus) as among 100 of the worst invasive species in Europe. For each of these alien bird species, the geographic range (native and introduced range), the introduction pathway, the general impacts and the management methods are presented. PMID:20919578

  13. Early Eocene birds from La Borie, southern France

    2016-02-01

    Full Text Available The early Eocene locality of La Borie is located in the village of Saint-Papoul, in southern France. These Eocene flu-vio-lacustrine clay deposits have yielded numerous vertebrate remains. Mammalian taxa found in the fossiliferous levels indicate an age near the reference level MP 8–9, which corresponds to the middle Ypresian, early Eocene. Here we provide a detailed description of the avian remains that were preliminarily reported in a recent study of the vertebrate fauna from La Borie. A maxilla, a quadrate, cervical vertebrae, a femur and two tibiotarsi are assigned to the giant ground bird Gastornis parisiensis (Gastornithidae. These new avian remains add to the fossil record of Gastornis, which is known from the late Paleocene to middle Eocene of Europe, early Eocene of Asia and early Eocene of North America. Gastornis parisiensis differs from the North American Gastornis giganteus in several features, including the more ventral position of the narial openings and the slender orbital process of quadrate. Two tibiotarsi and one tarsometatarsus are assigned to a new genus and species of Geranoididae, Galligeranoides boriensis gen. et sp. nov. So far, this family was known only from the early and middle Eocene of North America. The fossils from La Borie constitute the first record of the Geranoididae in Europe. We show that Gastornis coexisted with the Geranoididae in the early Eocene of both Europe (La Borie and North America (Willwood Formation. The presence of Geranoididae and the large flightless bird Gastornis on either side of the present-day North Atlantic provides further evidence that a high-latitude land connection existed between Europe and North America in the early Eocene.

    Beak and feather disease is caused by Circovirus, which affects actively growing beak and feather cells of avian species. The disease affects mainly young birds while older birds may overcome the disease with few lasting effects. Due to lack of treatment, the only way to control the disease is through hygiene and early diagnosis.

    Using ESO's Very Large Telescope, an international team of astronomers [1] has discovered a stunning rare case of a triple merger of galaxies. This system, which astronomers have dubbed 'The Bird' - albeit it also bears resemblance with a cosmic Tinker Bell - is composed of two massive spiral galaxies and a third irregular galaxy. ESO PR Photo 55a/07 ESO PR Photo 55a/07 The Tinker Bell Triplet The galaxy ESO 593-IG 008, or IRAS 19115-2124, was previously merely known as an interacting pair of galaxies at a distance of 650 million light-years. But surprises were revealed by observations made with the NACO instrument attached to ESO's VLT, which peered through the all-pervasive dust clouds, using adaptive optics to resolve the finest details [2]. Underneath the chaotic appearance of the optical Hubble images - retrieved from the Hubble Space Telescope archive - the NACO images show two unmistakable galaxies, one a barred spiral while the other is more irregular. The surprise lay in the clear identification of a third, clearly separate component, an irregular, yet fairly massive galaxy that seems to be forming stars at a frantic rate. "Examples of mergers of three galaxies of roughly similar sizes are rare," says Petri Väisänen, lead author of the paper reporting the results. "Only the near-infrared VLT observations made it possible to identify the triple merger nature of the system in this case." Because of the resemblance of the system to a bird, the object was dubbed as such, with the 'head' being the third component, and the 'heart' and 'body' making the two major galaxy nuclei in-between of tidal tails, the 'wings'. The latter extend more than 100,000 light-years, or the size of our own Milky Way. ESO PR Photo 55b/07 ESO PR Photo 55b/07 Anatomy of a Bird Subsequent optical spectroscopy with the new Southern African Large Telescope, and archive mid-infrared data from the NASA Spitzer space observatory, confirmed the separate nature of the 'head', but also added

    Parasite host switches may trigger disease emergence, but prehistoric host ranges are often unknowable. Lymphatic filariasis and loiasis are major human diseases caused by the insect-borne filarial nematodes Brugia, Wuchereria and Loa. Here we show that the genomes of these nematodes and seven tropical bird lineages exclusively share a novel retrotransposon, AviRTE, resulting from horizontal transfer (HT). AviRTE subfamilies exhibit 83-99% nucleotide identity between genomes, and their phylogenetic distribution, paleobiogeography and invasion times suggest that HTs involved filarial nematodes. The HTs between bird and nematode genomes took place in two pantropical waves, >25-22 million years ago (Myr ago) involving the Brugia/Wuchereria lineage and >20-17 Myr ago involving the Loa lineage. Contrary to the expectation from the mammal-dominated host range of filarial nematodes, we hypothesize that these major human pathogens may have independently evolved from bird endoparasites that formerly infected the global breadth of avian biodiversity.

    Full Text Available The Mongol Empire, the largest contiguous empire the world has ever known, had, among other things, a goodly number of falconers, poultry raisers, birdcatchers, cooks, and other experts on various aspects of birding. We have records of this, largely in the Yinshan Zhengyao, the court nutrition manual of the Mongol empire in China (the Yuan Dynasty. It discusses in some detail 22 bird taxa, from swans to chickens. The Huihui Yaofang, a medical encyclopedia, lists ten taxa used medicinally. Marco Polo also made notes on Mongol bird use. There are a few other records. This allows us to draw conclusions about Mongol ornithology, which apparently was sophisticated and detailed.

Using real-time, hydrolysis probe-based, reverse transcriptase PCR as the reference method, influenza A sensitivity was 97.3% for Xpert Flu, 95.9% for direct fluorescent antibody testing, 62.2% for BinaxNOW, and 71.6% for BD Directigen. Influenza B sensitivity was 100% for Xpert Flu and direct fluorescent antibody testing, 54.5% for BinaxNOW, and 48.5% for BD Directigen. Specificity for influenza A was 100% for Xpert Flu, BinaxNOW, and BD Directigen, and 99.2% for direct fluorescent antibody testing. All methods demonstrated 100% specificity for influenza B.

Nasopharyngeal washes and pharyngeal gargles were used to determine the effectiveness of the assay as applied to different types of routinely collected clinical samples. All specimens had been previously shown to contain influenza A virus by virus isolation in tissue culture. Directigen FLU-A was 90% sensitive (95% confidence interval, 56 to 99.7%) with nasopharyngeal washes but only 39% sensitive (95% confidence interval, 17 to 64%) with pharyngeal gargles (P = 0.018) when used with samples containing similar amounts of infectious virus (50% tissue culture infective dose, 1.0 to 4.5). The intensity of the positive reaction with Directigen FLU-A did not correlate with the amount of virus in the specimens. Directigen FLU-A was found to detect cell-associated antigen more readily than free virus; only 20 infected cells were required to identify cell-associated influenza A virus antigen, whereas the limit of detection for free virus was 1.63 x 10(3) infectious virus particles. These findings suggest that Directigen FLU-A detects the cell-associated antigen present in clinical specimens rather than free virus. In addition, Directigen FLU-A detected avian and swine influenza A viruses in both cloacal swabs (75% sensitivity) and swine lung homogenates (86% sensitivity), indicating its potential usefulness in the surveillance of nonhuman influenza A viruses.

    Respiratory infections, particularly those caused by influenza viruses, represent the third-most important cause of death in the world due to infectious diseases. Nevertheless, despite the enormous publicity attracted by epidemics due to these viruses, laboratory diagnosis, documentation and recording of respiratory diseases is still unsatisfactory. Available diagnostic tests capable of providing results rapidly are either limited and insufficiently sensitive or highly sensitive and specific but insufficiently rapid. Considerable investment and research efforts have been made towards the development of new diagnostics for influenza A and B viruses and the Xpert(®) Flu assay (Cepheid(®), CA, USA) has emerged as one of the most promising. In this article, we review current knowledge of the Xpert Flu test, discuss its potential value as a point-of-care test and outline the potential leads for future development. PMID:24707995

  14. Poisonous birds: A timely review.

    Science.gov (United States)

    Ligabue-Braun, Rodrigo; Carlini, Célia Regina

    2015-06-01

    Until very recently, toxicity was not considered a trait observed in birds, but works published in the last two decades started to shed light on this subject. Poisonous birds are rare (or little studied), and comprise Pitohui and Ifrita birds from Papua New Guinea, the European quail, the Spoor-winged goose, the Hoopees, the North American Ruffed grouse, the Bronzewings, and the Red warbler. A hundred more species are considered unpalatable or malodorous to humans and other animals. The present review intends to present the current understanding of bird toxicity, possibly pointing to an ignored research field. Whenever possible, biochemical characteristics of these poisons and their effects on humans and other animals are discussed, along with historical aspects of poison discovery and evolutionary hypothesis regarding their function.

    Many birders in the United States, Canada, and Mexico are critical participants in bird monitoring and conservation activities. This linkage between recreational birders and avian conservation surveys is not new. It was established long before the internet and long before any fast communication facilitated the connection of birders to scientists. It started because a few key individuals realized that birding with a purpose added a new and important dimension to a recreational activity—and birders loved the idea that they were helping to study and conserve the birds they watch. And they still do today.

    In 2008, avian bornaviruses (ABV) were identified as the cause of proventricular dilatation disease (PDD). PDD is a significant condition of captive parrots first identified in the late 1970s. ABV infection has subsequently been shown to be widespread in wild waterfowl across the United States and Canada where the virus infects 10-20% of some populations of ducks, geese and swans. In most cases birds appear to be healthy and unaffected by the presence of the virus; however, infection can also result in severe non-suppurative encephalitis and lesions similar to those seen in parrots with PDD. ABVs are genetically diverse with seven identified genotypes in parrots and one in canaries. A unique goose genotype (ABV-CG) predominates in waterfowl in Canada and the northern United States. ABV appears to be endemic in North American waterfowl, in comparison to what appears to be an emerging disease in parrots. It is not known whether ABV can spread between waterfowl and parrots. The discovery of ABV infection in North American waterfowl suggests that European waterfowl should be evaluated for the presence of ABV, and also as a possible reservoir species for Borna disease virus (BDV), a related neurotropic virus affecting horses and sheep in central Europe. Although investigations have suggested that BDV is likely derived from a wildlife reservoir, for which the shrew and water vole are currently prime candidates, we suggest that the existence of other mammalian and avian reservoirs should not be discounted.

    How birds orientate and navigate over long distances, remains one of the subjects of ornithology eliciting much interest. Birds use combinations of different sources of information to find direction and position. Some of these are the geomagnetic field, celestial bodies, mosaic and gradient maps, sound, smell, idiotetic information and others. Different species use different combinations of sources. This ability is partially inherent and partially learned.

    2014-01-01

    The fact is that 5-10% of the global adult population and 20-30% of children worldwide catch the flu every year. The illness can lead to hospitalisation and death, mainly in people who are considered high-risk (infants, the elderly, and those with chronic illnesses). According to the WHO, every year, flu epidemics are responsible for approximately three to five million cases of serious illness and for 250,000 to 500,000 deaths worldwide.   Vaccination is the most effective way of avoiding the illness and any serious consequences and protecting those around you. Safe and effective vaccines are available and have been used for more than 60 years. Remember, anyone working on the CERN site who wishes to be vaccinated against seasonal flu should go to the Infirmary (Building 57, ground floor) with their dose of vaccine. The Medical Service will issue a prescription on the day of the vaccination for the purposes of reimbursement through UNIQA. NB: The Medical Service cannot provide this vaccinat...

  9. Lab-on-a-bird: biophysical monitoring of flying birds.

    Directory of Open Access Journals (Sweden)

    Abdurrahman Gumus

    Full Text Available The metabolism of birds is finely tuned to their activities and environments, and thus research on avian systems can play an important role in understanding organismal responses to environmental changes. At present, however, the physiological monitoring of bird metabolism is limited by the inability to take real-time measurements of key metabolites during flight. In this study, we present an implantable biosensor system that can be used for continuous monitoring of uric acid levels of birds during various activities including flight. The system consists of a needle-type enzymatic biosensor for the amperometric detection of uric acid in interstitial fluids. A lightweight two-electrode potentiostat system drives the biosensor, reads the corresponding output current and wirelessly transfers the data or records to flash memory. We show how the device can be used to monitor, in real time, the effects of short-term flight and rest cycles on the uric acid levels of pigeons. In addition, we demonstrate that our device has the ability to measure uric acid level increase in homing pigeons while they fly freely. Successful application of the sensor in migratory birds could open up a new way of studying birds in flight which would lead to a better understanding of the ecology and biology of avian movements.

  18. Birds as predators in tropical agroforestry systems.

    2008-04-01

    Insectivorous birds reduce arthropod abundances and their damage to plants in some, but not all, studies where predation by birds has been assessed. The variation in bird effects may be due to characteristics such as plant productivity or quality, habitat complexity, and/or species diversity of predator and prey assemblages. Since agroforestry systems vary in such characteristics, these systems provide a good starting point for understanding when and where we can expect predation by birds to be important. We analyze data from bird exclosure studies in forests and agroforestry systems to ask whether birds consistently reduce their arthropod prey base and whether bird predation differs between forests and agroforestry systems. Further, we focus on agroforestry systems to ask whether the magnitude of bird predation (1) differs between canopy trees and understory plants, (2) differs when migratory birds are present or absent, and (3) correlates with bird abundance and diversity. We found that, across all studies, birds reduce all arthropods, herbivores, carnivores, and plant damage. We observed no difference in the magnitude of bird effects between agroforestry systems and forests despite simplified habitat structure and plant diversity in agroforests. Within agroforestry systems, bird reduction of arthropods was greater in the canopy than the crop layer. Top-down effects of bird predation were especially strong during censuses when migratory birds were present in agroforestry systems. Importantly, the diversity of the predator assemblage correlated with the magnitude of predator effects; where the diversity of birds, especially migratory birds, was greater, birds reduced arthropod densities to a greater extent. We outline potential mechanisms for relationships between bird predator, insect prey, and habitat characteristics, and we suggest future studies using tropical agroforests as a model system to further test these areas of ecological theory.

  19. Do birds sleep in flight?

    Science.gov (United States)

    Rattenborg, Niels C.

    2006-09-01

    The following review examines the evidence for sleep in flying birds. The daily need to sleep in most animals has led to the common belief that birds, such as the common swift ( Apus apus), which spend the night on the wing, sleep in flight. The electroencephalogram (EEG) recordings required to detect sleep in flight have not been performed, however, rendering the evidence for sleep in flight circumstantial. The neurophysiology of sleep and flight suggests that some types of sleep might be compatible with flight. As in mammals, birds exhibit two types of sleep, slow-wave sleep (SWS) and rapid eye-movement (REM) sleep. Whereas, SWS can occur in one or both brain hemispheres at a time, REM sleep only occurs bihemispherically. During unihemispheric SWS, the eye connected to the awake hemisphere remains open, a state that may allow birds to visually navigate during sleep in flight. Bihemispheric SWS may also be possible during flight when constant visual monitoring of the environment is unnecessary. Nevertheless, the reduction in muscle tone that usually accompanies REM sleep makes it unlikely that birds enter this state in flight. Upon landing, birds may need to recover the components of sleep that are incompatible with flight. Periods of undisturbed postflight recovery sleep may be essential for maintaining adaptive brain function during wakefulness. The recent miniaturization of EEG recording devices now makes it possible to measure brain activity in flight. Determining if and how birds sleep in flight will contribute to our understanding of a largely unexplored aspect of avian behavior and may also provide insight into the function of sleep.

  20. Dosage compensation is less effective in birds than in mammals

    Directory of Open Access Journals (Sweden)

    Itoh Yuichiro

    2007-03-01

    Full Text Available Abstract Background In animals with heteromorphic sex chromosomes, dosage compensation of sex-chromosome genes is thought to be critical for species survival. Diverse molecular mechanisms have evolved to effectively balance the expressed dose of X-linked genes between XX and XY animals, and to balance expression of X and autosomal genes. Dosage compensation is not understood in birds, in which females (ZW and males (ZZ differ in the number of Z chromosomes. Results Using microarray analysis, we compared the male:female ratio of expression of sets of Z-linked and autosomal genes in two bird species, zebra finch and chicken, and in two mammalian species, mouse and human. Male:female ratios of expression were significantly higher for Z genes than for autosomal genes in several finch and chicken tissues. In contrast, in mouse and human the male:female ratio of expression of X-linked genes is quite similar to that of autosomal genes, indicating effective dosage compensation even in humans, in which a significant percentage of genes escape X-inactivation. Conclusion Birds represent an unprecedented case in which genes on one sex chromosome are expressed on average at constitutively higher levels in one sex compared with the other. Sex-chromosome dosage compensation is surprisingly ineffective in birds, suggesting that some genomes can do without effective sex-specific sex-chromosome dosage compensation mechanisms.

  1. Birds and polycyclic aromatic hydrocarbons

    Science.gov (United States)

    Albers, P.H.

    2006-01-01

    Polycyclic aromatic hydrocarbons (PAH) are present throughout the global environment and are produced naturally and by activities of humans. Effects of PAH on birds have been determined by studies employing egg injection, egg immersion, egg shell application, single and multiple oral doses, subcutaneous injection, and chemical analysis of field-collected eggs and tissue. The four-to six-ring aromatic compounds are the most toxic to embryos, young birds, and adult birds. For embryos, effects include death, developmental abnormalities, and a variety of cellular and biochemical responses. For adult and young birds, effects include reduced egg production and hatching, increased clutch or brood abandonment, reduced growth, increased organweights, and a variety of biochemical responses. Trophic level accumulation is unlikely. Environmental exposure to PAH in areas of high human population or habitats affected by recent petroleum spills might be sufficient to adversely affect reproduction. Evidence of long-term effects of elevated concentrations of environmental PAH on bird populations is very limited and the mechanisms of effect are unclear.

  2. FluTyper-an algorithm for automated typing and subtyping of the influenza virus from high resolution mass spectral data

    Directory of Open Access Journals (Sweden)

    Schwahn Alexander B

    2010-05-01

    Full Text Available Abstract Background High resolution mass spectrometry has been employed to rapidly and accurately type and subtype influenza viruses. The detection of signature peptides with unique theoretical masses enables the unequivocal assignment of the type and subtype of a given strain. This analysis has, to date, required the manual inspection of mass spectra of whole virus and antigen digests. Results A computer algorithm, FluTyper, has been designed and implemented to achieve the automated analysis of MALDI mass spectra recorded for proteolytic digests of the whole influenza virus and antigens. FluTyper incorporates the use of established signature peptides and newly developed naïve Bayes classifiers for four common influenza antigens, hemagglutinin, neuraminidase, nucleoprotein, and matrix protein 1, to type and subtype the influenza virus based on their detection within proteolytic peptide mass maps. Theoretical and experimental testing of the classifiers demonstrates their applicability at protein coverage rates normally achievable in mass mapping experiments. The application of FluTyper to whole virus and antigen digests of a range of different strains of the influenza virus is demonstrated. Conclusions FluTyper algorithm facilitates the rapid and automated typing and subtyping of the influenza virus from mass spectral data. The newly developed naïve Bayes classifiers increase the confidence of influenza virus subtyping, especially where signature peptides are not detected. FluTyper is expected to popularize the use of mass spectrometry to characterize influenza viruses.

    Objective To develop a participatory system for monitoring the activity of influenza-like-illness among the United States general population. Introduction The emergence of new influenza strains including H1N1, H5N1, H3N2v as well as other respiratory pathogens such as SARS, along with generally weak information about household and community transmission of influenza, enforce the need for augmented influenza surveillance. At the same time, Internet penetration and access has grown, with 82% of American adults using the Internet [1], enabling transfer and communication of information that can be collected and aggregated in near real-time. Surveillance targeted towards influenza in other countries, and towards malaria in India, has previously been executed with good user engagement [2,3]. In this study, we created an online participatory influenza surveillance tool in the United States, called Flu Near You. Methods Volunteer users were primarily solicited via collaboration with the American Public Health Association and their members’ networks starting Oct. 24, 2011. Upon registration, each user is sent a weekly email, taking them to the Flu Near You website. On the website they fill in a short survey asking if they had any of 10 symptoms: fever, cough, sore throat, shortness of breath, chills/night sweats, fatigue, nausea or vomiting, diarrhea, body aches and headache, in the last week. Users can also enroll their household members and enter information in for them weekly. A map of influenza activity is made available to users, and anyone accessing the website [Figure 1]. On the map, the number of individuals reporting with no symptoms, some symptoms, or Influenza-like illness are visualized, aggregated to the zip code level. Users can also compare the contributed data with other surveillance systems: the Centers for Disease Control and Prevention, and Google Flu Trends for the same time period [Figure 1]. We also obtained user feedback through a survey in early

    Respiratory tract infections caused by influenza A and B viruses often present nonspecifically, and a rapid, high-throughput laboratory technique that can identify influenza viruses is clinically and epidemiologically desirable. The PLEX-ID Flu assay (Abbott Molecular Inc., Des Plaines, IL) incorporates multilocus PCR and electrospray ionization-mass spectrometry to detect and differentiate influenza A 2009 H1N1 (H1N1-p), seasonal H1N1 (H1N1-s), influenza A H3N2, and influenza B viruses in nasopharyngeal swab (NPS) specimens. The clinical performance characteristics of the PLEX-ID Flu assay in symptomatic patients were determined in this multicenter trial. A total of 2,617 prospectively and retrospectively collected NPS specimens from patients with influenza-like illness between February 2008 and 28 May 2010 were eligible for inclusion in the study. Each specimen was tested in parallel by the PLEX-ID Flu assay and by the Prodesse ProFLU+ assay (Prodesse Inc., Madison, WI), to detect influenza A and B viruses. Specimens testing positive for influenza A virus by ProFLU+ were subtyped as H1N1-p, H1N1-s, or H3N2 by using the ProFAST+ assay (Gen-Probe Prodesse Inc.). The reproducibility of the PLEX-ID Flu assay ranged from 98.3 to 100.0%, as determined by testing a nine-specimen panel at three clinical sites on each of 5 days. Positive percent agreements (PPAs) and negative percent agreements (NPAs) of the PLEX-ID Flu assay were 94.5% and 99.0% for influenza A virus and 96.0% and 99.9% for influenza B virus, respectively. For the influenza A virus subtyping characterization, the PLEX-ID Flu assay had PPAs and NPAs of 98.3% and 97.5% for H1N1-p, 88.6% and 100.0% for H1N1-s, and 98.0% and 99.9% for H3N2, respectively. The overall agreements between the PLEX-ID and Prodesse ProFLU+/ProFAST+ assays were 97.1 to 100.0%. Bidirectional Sanger sequencing analysis revealed that 87.5% of 96 discrepant results between the PLEX-ID Flu and ProFLU+/ProFAST+ assays were found upon

  12. Determining symptoms for chest radiographs in patients with swine flu (H1N1)

    International Nuclear Information System (INIS)

    The question arises about the chest X-ray findings and clinical symptoms in swine flu and about the most important clinical finding when correlated with the chest radiograph. Should physicians order a chest X-ray in each patient suspected of having swine flu? There were 179 patients with a high suspicion of swine flu. All 179 patients had an initial chest radiograph. As many as 65 males (representing 56% of the projected study population) had a normal chest radiograph, while 35 males (representing 55.6% of the study population) had an abnormal chest X-ray. As many as 51 females (representing 44% of the population) had a normal chest X-ray, while 20 females (representing 44% of the study population) had abnormal chest X-rays. Polymerase chain reaction (PCR) was not a determining factor for normal vs. abnormal chest X-ray (CXR). Rapid antigen test was not a determining factor for normal vs. abnormal CXR. Fever was not a determining factor for normal vs. abnormal CXR. Cough appears to be a determining factor for normal vs. abnormal CXR. Sore throat appears to be a determining factor for normal vs. abnormal CXR. Chest pain was not a determining factor for normal vs. abnormal CXR. Presence of cough with PCR was statistically significant. In my opinion, chest radiographs in patients with suspected H1N1 should only be obtained if there is a cough or sore throat. Other symptoms associated with H1N1 do not warrant a chest radiograph unless absolutely necessary

    Google Flu Trends (GFT) was the first application of big data in the public health field. GFT was open online in 2009 and attracted worldwide attention immediately. However, GFT failed catching the 2009 pandemic H1N1 and kept overestimating the intensity of influenza-like illness in the 2012-2014 season in the United States. GFT model has been updated for three times since 2009, making its prediction bias controlled. Here, we summarized the mechanism GFT worked, the strategy GFT used to update, and its influence on public health. PMID:26310351

    FLUOR, which has been operational on CHARA since 2002, is an infrared fiber beam combiner. The telescope array will soon be fitted with an adaptive optics system, which will enhance the interferometer performance. In this framework, FLUOR has been entirely redeveloped and will be able to measure visibilities with higher accuracy and better sensitivity. The technical upgrades consist of improving some existing systems and developing new features. The bench, which is now remotely operable, primarily offers spectral dispersion (long fringes scanning), a more sensitive camera and a Fourier Transform Spectrometer mode. This paper presents the detailed opto-mechanical design of JouFLU (FLUOR rejuvenation), and the current instrument status.

    Lee, Polly

    Swine flu has brought about the need to implement policy quickly, not only in healthcare but also in healthcare education, which has considered greater use of e-learning during potential disruption to classroom teaching. This article looks at measuring the success of these alternative teaching methods by using the known tangible benefits of e-learning. Consideration should also be given to supporting students on placements during this time, and as a consequence, some possible future areas for development are identified. PMID:19791673

    Abstract Here we present a review of the literature of influenza modeling studies, and discuss how these models can provide insights into the future of the currently circulating novel strain of influenza A (H1N1), formerly known as swine flu. We discuss how the feasibility of controlling an epidemic critically depends on the value of the Basic Reproduction Number (R0). The R0 for novel influenza A (H1N1) has recently been estimated to be between 1.4 and 1.6. This value is below values of R0 e...

    Full Text Available A influenza ou, como é conhecida comumente, a gripe, é uma doença infecciosa aguda causada por um grupo de vírus (com mesmo nome que acomete várias espécies de animais, desde felinos até aves, passando por humanos. Há cerca de 10 anos têm sido descritos, inicialmente em Hong Kong, surtos de gripe causados por vírus aviários em populações humanas. A seguir, foram descritos surtos na Holanda e no Canadá. Portanto, indaga-se: o mundo corre o risco de um novo surto semelhante ao de 1918, porém com uma população mundial quatro a cinco vezes maior? Qual a velocidade de disseminação desse vírus, visto que as viagens internacionais já não são feitas em navios lentos, mas sim em jatos supersônicos que dão a volta ao mundo em algumas horas? Antes de tudo, o que torna esse vírus tão problemático? Para nós, profissionais de laboratório, é preocupante a questão do diagnóstico etiológico dessas infecções. Como ressaltamos, os quadros de gripe podem ser causados por vários agentes. Portanto, o diagnostico etiológico, básico para intervenções terapêuticas e para que se defina a ocorrência da epidemia, passa a ter relevância ainda maior.Influenza, or as it is best known, "flu", is an acute respiratory infection caused by a virus that affects many different animal species from felines to birds, including humans.Ten years ago, initialy in Hong Kong and after that in Holand and Canada, outbreaks of avian flu have been increasingly reported in human beings. The question is innevitable: are we in the surge of a new flu pandemic like the one we had in 1918? The perspective is even worse now that we have five times the world population and the international travels are no longer made in slow-going ships but instead in super fast jet planes. For us, laboratory professionals, the question of the laboratory diagnosis is crucial. Considering that so many different viruses are associated with respiratory infections and therapeutic

    The perceived safety of vaccination is an important explanatory factor for vaccine uptake and, consequently, for rates of illness and death. The objectives of this study were (1) to evaluate Canadian attitudes around the safety of the H1N1 vaccine during the fall 2009 influenza pandemic and (2) to consider how public health communications can leverage the Internet to counteract, in real time, anti-vaccine sentiment. We surveyed a random sample of 175,257 Canadian web users from October 27 to November 19, 2009, about their perceptions of the safety of the HINI vaccine. In an independent analysis, we also assessed the popularity of online flu vaccine-related information using a tool developed for this purpose. A total of 27,382 unique online participants answered the survey (15.6% response rate). Of the respondents, 23.4% considered the vaccine safe, 41.4% thought it was unsafe and 35.2% reported ambivalence over its safety. Websites and blog posts with anti-vaccine sentiment remained popular during the course of the pandemic. Current public health communication and education strategies about the flu vaccine can be complemented by web analytics that identify, track and neutralize anti-vaccine sentiment on the Internet, thus increasing perceived vaccine safety. Counter-marketing strategies can be transparent and collaborative, engaging online "influencers" who spread misinformation.

    Full Text Available Abstract Background People often search for information on influenza A(H1N1v prevention on the web. The extent to which information found on the Internet is consistent with recommendations issued by the World Health Organization is unknown. Methods We conducted a search for "swine flu" accessing 3 of the most popular search engines through different proxy servers located in 4 English-speaking countries (Australia, Canada, UK, USA. We explored each site resulting from the searches, up to 4 clicks starting from the search engine page, analyzing availability of World Health Organization recommendations for swine flu prevention. Results Information on hand cleaning was reported on 79% of the 147 websites analyzed; staying home when sick was reported on 77.5% of the websites; disposing tissues after sneezing on 75.5% of the websites. Availability of other recommendations was lower. The probability of finding preventative recommendations consistent with World Health Organization varied by country, type of website, and search engine. Conclusions Despite media coverage on H1N1 influenza, relevant information for prevention is not easily found on the web. Strategies to improve information delivery to the general public through this channel should be improved.

    Full Text Available Introduction: Iran, similar to other countries, had faced H1N1 flu outbreak in 2009. In order to assess its transmission dynamic, we estimated its force of infection (β and basic reproductive number (R 0 . Methods: Within a middle size primary school in Iran, we actively followed students and detected flu-like syndrome among students and their families in the first three months of academic year; October through December 2009. We estimated the probability of disease transmission within families (β fitting random effects Poisson regression model. Moreover, R 0 within the school was computed based on the number of detected cases. Results: In 452 students, 204 influenza-like syndromes were detected. The estimated β within families was 0.10; increasing one infectious member within each family was associated with 30% increase in this number. The estimated R 0 for the first month was 1.21 (95% C.I.: 0.99, 1.47; corresponding numbers for the first two and first three months were 1.28 (95% C.I.: 1.05, 1.54 and 1.32 (95% C.I.: 1.11, 1.59, respectively. Conclusion: It seems that the dynamic transmission of H1N1 virus was more or less comparable with that in other seasonal species. Our findings showed that the virus mainly circulated among students within schools. In addition, it seems that the transmission rate within families was relatively high.

    Background There is a need to increase influenza vaccination rates in England particularly among those who are under 65 years of age and at-risk because of other conditions and treatments. Objective To understand the profile of people accessing flu vaccination services within a large pharmacy chain. Method Pharmacists requested people who had been vaccinated in 2014/15 to complete a questionnaire. Data was captured electronically on vaccine delivery levels across 1201 pharmacies. Deprivation profiles were calculated using the Carstairs index. Results 1741 patients from a total of 55 pharmacies completed the survey. Convenience and accessibility remain the key reasons for attending pharmacy. Pharmacy services are accessed by people from all postcode areas, including some from the most deprived localities. Conclusion Pharmacy flu vaccination services complement those provided by general practitioners to help improve overall coverage and vaccination rates for patients in at-risk groups. These services are highly accessed by patients from all socio demographic areas, and seem to be particularly attractive to carers, frontline healthcare workers, and those of working age.

    2013-01-01

    Nearly one in five bird species has separate breeding and overwintering distributions, and the regular migrations of these species cause a substantial seasonal redistribution of avian diversity across the world. However, despite its ecological importance, bird migration has been largely ignored in studies of global avian biodiversity, with few studies having addressed it from a macroecological perspective. Here, we analyse a dataset on the global distribution of the world's birds in order to examine global spatial patterns in the diversity of migratory species, including: the seasonal variation in overall species diversity due to migration; the contribution of migratory birds to local bird diversity; and the distribution of narrow-range and threatened migratory birds. Our analyses reveal a striking asymmetry between the Northern and Southern hemispheres, evident in all of the patterns investigated. The highest migratory bird diversity was found in the Northern Hemisphere, with high inter-continental turnover in species composition between breeding and non-breeding seasons, and extensive regions (at high latitudes) where migratory birds constitute the majority of the local avifauna. Threatened migratory birds are concentrated mainly in Central and Southern Asia, whereas narrow-range migratory species are mainly found in Central America, the Himalayas and Patagonia. Overall, global patterns in the diversity of migratory birds indicate that bird migration is mainly a Northern Hemisphere phenomenon. The asymmetry between the Northern and Southern hemispheres could not have easily been predicted from the combined results of regional scale studies, highlighting the importance of a global perspective.

    2016-01-01

    At a time of unprecedented biodiversity loss, researchers are increasingly recognizing the broad range of benefits provided to humankind by nature. However, as people live more urbanized lifestyles there is a progressive disengagement with the natural world that diminishes these benefits and discourages positive environmental behaviour. The provision of food for garden birds is an increasing global phenomenon, and provides a readily accessible way for people to counter this trend. Yet despite its popularity, quite why people feed birds remains poorly understood. We explore three loosely defined motivations behind bird feeding: that it provides psychological benefits, is due to a concern about bird welfare, and/or is due to a more general orientation towards nature. We quantitatively surveyed households from urban towns in southern England to explore attitudes and actions towards garden bird feeding. Each household scored three Likert statements relating to each of the three motivations. We found that people who fed birds regularly felt more relaxed and connected to nature when they watched garden birds, and perceived that bird feeding is beneficial for bird welfare while investing time in minimising associated risks. Finally, feeding birds may be an expression of a wider orientation towards nature. Overall, we found that the feelings of being relaxed and connected to nature were the strongest drivers. As urban expansion continues both to threaten species conservation and to change peoples’ relationship with the natural world, feeding birds may provide an important tool for engaging people with nature to the benefit of both people and conservation.

The highest migratory bird diversity was found in the Northern Hemisphere, with high inter-continental turnover in species composition between breeding and non-breeding seasons, and extensive regions (at high latitudes where migratory birds constitute the majority of the local avifauna. Threatened migratory birds are concentrated mainly in Central and Southern Asia, whereas narrow-range migratory species are mainly found in Central America, the Himalayas and Patagonia. Overall, global patterns in the diversity of migratory birds indicate that bird migration is mainly a Northern Hemisphere phenomenon. The asymmetry between the Northern and Southern hemispheres could not have easily been predicted from the combined results of regional scale studies, highlighting the importance of a global perspective.
