    With the challenges confronting North America's elk herds today, a bacteria that causes a nonfatal disease in a few elk herds seems an unlikely addition to the list. Fragmentation of habitat, dwindling bull-cow ratios, grazing competition from livestock on public rangelands, or the crowding of favorite hunting spots all seem like far more urgent matters to elk junkies. But a twist of fate an a national campaign to eradicate this seemingly innocuous bacterium have put brucellosis on the front burner.

  3. Control of brucellosis in Iraq

    International Nuclear Information System (INIS)

    Brucellosis is the most widespread zoonotic disease and considered a great problem of major economic importance in most countries, particularly in those where no eradication programme is applied. In developing countries, ovine brucellosis is still a more frequent source of human infection, and attempts at eradication or campaigns for its control have often met with considerable difficulties. The Iraqi government has long been concerned with the danger brucellosis represents to public health and economy. The Central Veterinary Diagnostic Laboratory at Baghdad has a long history of work on brucellosis since in 1977-1985 different biotypes of Brucella melitensis, in particular biotype III, were prevalent and isolated from aborted foetuses and from sheep and goat milk. In addition, two biotypes of Brucella abortus were isolated from aborted calves. As a result, goats, sheep and cattle have a very high risk of morbidity. Serious incidences of brucellosis have been observed in 12% of goats, 10% of sheep and 0.5% of cattle. Recently, Iraq has faced an increasing incidence of the disease, because of inadequate observation of the rules and regulations concerning its control. Accordingly, Iraq has initiated action in co-operation with Jordan, Lebanon and the Syrian Arab Republic in order to develop a regional project in the framework of the elimination, prevention and eradication programme established in 1995

    The paper describes the history and evolvement of brucellosis in China. It presents the variation of epidemic situation, epidemiological characteristics, application of vaccines and control in brief. Before 1980s, human and animal brucellosis was quite severe; during 1980s, the incidence of human and animal brucellosis was relatively low, and seemed to decrease during the decade. During 1990s, there were no obvious changes in the incidence of animal brucellosis, but the incidence of human brucellosis increased, especially from 1995 to 2001. There are not only some common characteristics but also some differences in brucellosis epidemiology relative to that reported in the rest of the world. For the entire country, B. melitensis was the predominant strain associated with outbreaks, and the epidemic peak is from February to June. Several Brucella vaccines have been used in China for prevention and control of brucellosis. such as B. abortus 104 M in humans, B. suis S2 in animals. The introduction of comprehensive measures has allowed great progress in the prevention and control of brucellosis in China. Surveillance points were set-up countrywide to estimate the epidemic situation. In addition, we discussed the new characteristics of brucellosis in China, the influence of the El Nino phenomenon on brucellosis epidemic situation, the phenomenon of antigenic interference between Brucella species and some disadvantages of live Brucella vaccines.

  5. Brucellosis: Epizootiologic and diagnostic challenge

    Directory of Open Access Journals (Sweden)

    2005-01-01

    Full Text Available Although it has been known as a separate etiological entity for almost 150 years, brucellosis is, on a global scale, one of the most frequent diseases that is transferred from animals to humans. It is present as an endemic disease in almost all countries of the Mediterranean Sea, which indicates that a large number of aspects in connection with the control and epizootiology of this disease still remain unexplained. Three of the six types of brucella have been officially confirmed in our country as well. They are Brucella melitensis biotip 3, Brucella suis biotip 2 and Brucella canis. Brucellosis is endemically present in Kosovo and Metohija province and in southern Serbia proper; over the past few years, the spread of brucellosis in sheep and goats as primary hosts for B. melitensis to new territories, mostly in Vojvodina province, has shown that risk analysis is one of the main factors in selecting and implementing control programmes. A correctly selected set of diagnostic tests yields reliable data in most cases, but interpretations of results are prone to result in subjective assessments as well. A special problem in the serological diagnosis of brucellosis is the cross reactivity of brucellas and some other bacteria, often a weak immunological response of the animal, or that the type of brucella that causes the infection determines the sensitivity and specificity of the applied tests, most often screenings tests. Due to the big economic losses resulting from disease control and eradication, and the serious risk to human health, brucellosis still poses an epizootiological, and, in particular, a diagnostic challenge.

    To show that brucellosis may trigger autoimmune hepatitis(AIH), in addition to nonspecific liver involvement and toxic hepatitis, due to a class effect of tetracycline family used for treatment. We present a female patient admitted to our hospital due to partially improved fatigue and elevated liver enzymes following doxycycline and streptomycin usage for brucellosis. Brucellosis is endemic in our country, Turkey. It may involve any organ in the body. Liver is frequently involved. Doxycycline used for treatment occasionally may lead to hepatotoxicity. AIH is a necroinflammatory disease of the liver. Certain drugs (e.g. Minocycline), toxins, and viruses (hepatitis B, hepatitis C, EBV, etc.) can trigger AIH. Only one case of AIH probably caused by doxycycline and brucellosis was reported. We discuss the relationship between brucellosis, AIH, and hepatotoxicity of doxycycline. Brucellosis may trigger AIH.

    Full Text Available Brucellosis, a bacterial zoonosis, is a disease caused by members of the genus Brucella . In Indonesia, brucellosis has known as a contagious reproductive disease in animals, however, only certain people know that brucellosis can be transmitted to human . Bovine brucellosis is characterised by one or more of the following signs : abortion, retained placenta . orchitis, epididymitis and, rarely, arthritis, with excretion of the organisms in uterine discharges and in milk . The Brucella organism is transmitted to human most commonly by ingestion of untreated milk or milk products or through the mucous membranes and wound of the skin . The severity of human disease varies, depending largely upon the infecting strain . Brucella abortus, B . melitensis. B . suis and B. canis are highly pathogenic for humans . Clinical symptoms of human brucellosis may include an intermittent fever, headaches, weakness, arthalgia, myalgia and weight loss . Occasional complications include arthritis, endocarditis, hepatitis granuloma, meningitis, orchitis dan osteomyelitis have also been reported . Brucellosis can also produce spontaneous abortion in pregnant woman . Diagnosis is based on the isolation of the organism and serology . Antibiotics are usually the mainstay of treatment and long-term treatment may be required . Brucellosis can be controlled by comprehensive campaigns to eradicate the disease by vaccination programme followed by test and slaughter of domestic animals which exhibit positive serologic reactions to brucellae.

  1. Persistence of brucellosis in pastoral systems.

    Science.gov (United States)

    Racloz, V; Schelling, E; Chitnis, N; Roth, F; Zinsstag, J

    2013-04-01

    Regarded as a highly contagious, zoonotic disease with worldwide distribution, brucellosis is endemic in many countries and settings and is responsible for a considerable economic and health-related burden. Limited information is available on the persistence and prevalence of brucellosis in pastoral communities, due to the difficulty in gathering information and to their mobility. However, since these communities are economically and culturally dependent on livestock, it is important to further determine the cause of persistent disease and develop possible methods for its management. The two main objectives of this paper are to review the literature, identifying various epidemiological and social factors that affect the persistence of brucellosis in pastoral ecosystems, and determine prevalence estimates within these communities. The general trend of the summarised studies indicates low-level, relatively stable transmission of brucellosis in pastoral areas, when compared to transmission in intensive and semi-intensive peri-urban production systems. A formal mathematical analysis can be undertaken using matrix models or coupled differential equations. This allows an examination of the various conditions under which the number of diseased, infected or exposed animals remains stable. The authors examined an existing mathematical differential equation model for brucellosis in Mongolia for its equilibrium conditions and found it reasonably robust, though clearly more data are needed to estimate threshold densities for brucellosis transmission in other regions of the world. However, the results indicate the importance of livestock demographic determinants for brucellosis persistence. The paper concludes that brucellosis remains largely persistent in pastoral areas of the world, despite (varying) control efforts. Plans to control brucellosis in pastoral settings should include ecological considerations, such as sustaining ecosystem services in pastoral areas. This

    Brucellosis is a zoonosis that affects several organs or systems. Skin involvement is nonspecific and it is reported to range between 0,4 and 17% of the patients with brucellosis. Here, we defined a 36-year-old female patient presented to our clinic with a clinical picture of recurrent attacks of vasculitis due to brucellosis for the first time. Skin involvement and vasculitic lesions as a finding of skin involvement are nonspecific in brucellosis. Therefore, in the regions like Turkey where brucellosis is endemic, brucellosis should be kept in mind necessarily in the differential diagnosis of vasculitis. PMID:27042369

    2011-01-01

    Full Text Available Brucellosis is one of the most important zoonotic diseases. Several complications may be seen during its clinical course. Here, we describe a patient who presented with complaints of fatigue, malaise, and intensive lumbar pain. He had been suffering from these complaints for nearly 1 month. It was learned that he lived in rural area, made and ate his own cheese. The Rose Bengal test was positive and Brucella standard tube agglutination was positive at 1/320 titer. Pedro Pons′ sign, an osteoarticular complication of brucellosis, was revealed with the aid of radiologic imaging. Osteoarticular involvement is common in the course of brucellosis. Deformation in vertebrae formerly known as Pedro Pons′ sign should be thought in brucellosis patients suffering from lumbar pain.

    The successful control of animal brucellosis and associated reduction in human exposure has limited the development of human brucellosis vaccines. However, the potential use of Brucella in bioterrorism or biowarfare suggests that direct intervention strategies are warranted. Although the dominant approach has explored the use of live attenuated vaccines, side-effects associated with their use has prevented widespread use in humans. Development of live, attenuated Brucella vaccines that are sa...

    Brucellosis is an important re-emerging zoonosis with a worldwide distribution. It is still an uncontrolled serious public health problem in many developing countries including India. Brucellosis in India is yet a very common but often neglected disease. Currently, Brucella melitensis accounts for most recorded cases globally with cattle emerging as a important reservoir with the few cases of B. suis. Isolated cases of non-terrestrial brucellosis and continuing transmission from wild animals have raised important epidemiological issues. Routine serological surveillance along with high clinical suspicion and screening of family members of index cases would be essential in delineating the real magnitude of human brucellosis in endemic countries. Increased business and leisure travel to endemic countries have led to diagnostic challenge in non-endemic areas. Laboratory testing is indispensable for diagnosis. Advances in newer rapid, sensitive, and specific testing methodologies and alternate treatment strategies are urgently needed. A safe and effective vaccine in human is not yet available. Prevention is dependent upon increasing public awareness through health education programmes and safe livestock practices. Active co-operation between health and veterinary services should be promoted. This review collates world literature and its impact to the discovery, isolation and diagnosis and epidemiology along with the control measures adapted in the Indian scenario.

    Full Text Available Brucellosis is a zoonosis caused by Brucella species. Brucella epididymo-orchitis had been reported in up to 20% of patients with brucellosis. This case was a male patient who developed Brucella epidiymo-orchitis and testicular abscess. He had fever, arthralgia and his right epididymis and right testicle were enlarged and tender. Ultrasound evaluation showed hypertrophy of the right epididymis and testis and moreover hypoechoic area within the testis. Brucella serology was positive and the patient did not respond completely to treatment with streptomycin, doxycycline, and rifampicina. Unilateral orchidectomy was decided. In areas where brucella infection is endemic brucella epididymo-orchitis should be considered in the differential diagnosis. Effective and rapid treatment is important. It should be noted that these patients may develop testicular abscess.

    Full Text Available Buffalo’s production represents an important option as input source in livestock systems located in areas with little profitability by cattle. In mostly farms, cattle and buffalos are breeding together, due that in Argentina, to carry out buffalo’s production is in an extensive way, with the aim to produce meat – mostly- milk – for this production nutritional supplements are used- and leathers. Brucellosis is zoonic illnesses from bacteria belong to Brucella which caused human human health problems by contaminated food ingestion or to those who are in touch with cattle. In Argentina, exist the National Control an Elimination Program for cattle Brucellosis, which include buffalos also, there is inclosed female vaccination and serologic segregation of positive reactants. Diagnosis techniques ruled for cattle brucellosis are BPA (Buffered Plate Agglutination, Tube seroaglutination and 2MercaptoEthanol. International reference test is Complement Fixation. By means of this present work, we pretend to evaluate the serologic diagnosis utility, ruled to the buffalos and compare obtained results by BPA, SAT and 2ME with Complement Fixation Test. In the present communication are presented results from the use of diagnosis techniques recommended by SENASA (National Service of Sanity and Quality Agro-Food to buffalo’s serums which belong to nine farms from NE Corrientes State. Obtained results show that association o BPA as Screening Test and SAT and 2ME as Confirmated Test has a valid correlation for the detection of positive animals with the reference technique Complement Fixation.

    Directory of Open Access Journals (Sweden)

    Smita Mangalgi

    2015-01-01

    Full Text Available Background: Human brucellosis is a disease with protean clinical manifestations. Despite many awareness programmes, it is still missed or wrongly diagnosed. This leads to chronic morbidity leading to misery and loss of working days. Aim and Objectives: To assess the microbiological, clinical and epidemiological aspects of human brucellosis. Materials and Methods: Patients with positive brucella screening test constituted the study material. A detailed laboratory, clinical, epidemiological study along with response to the treatment was analyzed. Results: Seroprevalence of brucellosis was found to be 1.75%. Brucellosis was clinically diagnosed in only 12.73% of cases. Fever, joint pain and low backache were the commonest symptoms. Close contact with animals and raw milk ingestion were the major sources of infection. Knowledge regarding brucellosis and its prevention was lacking in patients. Brucellosis was not considered as one of the differential diagnosis by the treating physicians. Conclusion: Brucellosis should be considered as one of the differential diagnosis in cases presenting with fever, low backache, arthritis and arthralgia. Laboratories should screen all the serum samples for brucella agglutinins by Rose Bengal Plate Test. Awareness regarding the prevention of brucellosis in the general population and regarding the existence of the disease among the doctors practicing in rural areas is needed

    2016-01-01

    The historical process of brucellosis extends back to humankind's first contact with animals. Although brucellosis is a sporadic disease observed in animals in certain regions of the world, it is an important disease in humans that can affect many organs and systems due to the consumption of contaminated milk or milk products. Studies have shown that the presence of Brucella dates back to 60 million years ago. In 450 BC, Hippocrates described a disease similar to brucellosis. Since Hippocrates' time, brucellosis has been characterized by fever. Our aim is to investigate selfless work undertaken by scientists on the epidemiology, diagnosis and clinical findings of brucellosis until today, and to gain a historical perspective about the disease that is as old as human history, still has importance today, causes economic losses in treated animals and harms human health.

    Full Text Available Objective: Brucellosis became a remarkable disease in Kosovo. But there is not a comprehensive epidemiological study about epidemiology and clinical course of this disease from Kosovo. The aim of our study is to present demographic and clinical data of patients with brucellosis at University Clinical Center of Kosovo. Methods: A retrospective study was performed for the patients with brucellosis treated in our clinic during years 2011- 2012. The data about demography, history of the disease, clinical presentations, serological test, serum biochemistry and reatment were collected from hospital medical records. The diagnosis of brucellosis based on clinical and laboratory findings. Results: This descriptive study included 47 patients, who 33 of them (70.2% were males. The mean age was 37.9 ± 19.3 years. The route of transmission of the disease was known in 28 59.5% of them. Direct contact with livestock in 22 (46.8% and ingestion of dairy products in six cases (12.7% were reported as the transmission route. The majority of patients (27 patients, 57.4% were from rural area. The main presenting symptoms were atigue, fever and arthralgia. Osteoarticular manifestations were the common forms of localized disease. Regarding to the therapy, 45 (95.7% of patients were treated with streptomycin and doxycycline for the first three weeks. Conclusion: Human brucellosis is not a common in Kosovo but there is a potential risk. Osteoarticular symptoms were the most common presentation reasons. The most effective and preferred treatment regimen was Streptomycin plus Doxycycline for the first three weeks, and Doxycycline plus Rifampicin thereafter. J Microbiol Infect Dis 2015;5(4: 147-150

    Full Text Available Introduction. Brucellosis is an acute, subacute or chronical disease, from the zoonosis group, caused by various types of bacteria belonging to genus Brucellae. It is transmitted to humans from domestic animals: goats, sheep, cattle, pigs and dogs. The course of the disease may either be asymptomatic, or produce a variety of clinical manifestations, ranging from light ones to extremely severe clinical forms. The aim of the study was to follow the clinical features of brucella infection in the hospital-treated patients, as well as its course and outcome. Material and Methods. The investigation included 15 patients, treated for brucella infection at the Clinic for infectious diseases during the last two years (2004 and 2005. Results. All patients were adults, their age ranged from 18 to 71, 49.96 on average. The epidemiological questionnaire was positive in all patients, confirming contacts with the ailing animals, or consumption of cheese made from milk of diseased animals. They all exhibited the classic symptoms - increased body temperature and shiver, fever, sweating, malaise and headache, the so called flu like state. The serum agglutination test was positive in respect to brucellosis, the titre ranged from 1:80 to 1:1280. Eight patients suffered excessive back pain, accompanied with impeded walk. In half of them magnetic resonance imaging confirmed the spondylodiscitis diagnosis. Three patients had clinical features of knee arthritis, two had bronchopneumonia, one pancreatitis, and one developed the signs of an acute kidney insufficiency. The outcome was favorable in all patients - They recuperated or healed completely. In one patient a relapse occurred, leading to the chronic course of the illness. Discussion. Although predominantly Mediterranean Brucellosis is a worldwide spread disease. During the last two years, an increased incidence of the disease has been observed. Conclusion.

    Full Text Available Brucellosis is an important zoonosis of worldwide distribution. Reliable epidemiologic brucellosis data covering approximately 90% of the cattle population in Brazil have been recently published. Therefore, considering the scarcity of information regarding the economic impact of bovine brucellosis in Brazil, the goal of this study was to estimate economic impact of brucellosis on the Brazilian cattle industry. Several parameters including abortion and perinatal mortality rates, temporary infertility, replacement costs, mortality, veterinary costs, milk and meat losses were considered in the model. Bovine brucellosis in Brazil results in an estimated loss of R$ 420,12 or R$ 226,47 for each individual dairy or beef infected female above 24 months of age, respectively. The total estimated losses in Brazil attributed to bovine brucellosis were estimated to be approximately R$ 892 million (equivalent to about 448 million American dollars. Every 1% increase or decrease in prevalence is expected to increase or decrease the economic burden of brucellosis in approximately 155 million Reais.

    Full Text Available Brucellosis, which is caused by Brucella spp., infects domestic and wild animals worldwide, as well as humans who have contact with infected animals or contaminated dairy products. In present-day epidemiological situation in Mongolia is not quiet, especially, zoonoses such us brucellosis have been broadly spreaded.Recently, we developed agar gel immunodiffusion (AGID test with polysaccharide (Poly-B antigen and an indirect enzyme-linked immunosorbent assay (i-ELISA using soluble antigen extracted from B. abortus 544 by n-lauroylsarcosine (sarcosine extracts and these tests could be used to differentiate naturally infected animals from vaccinated and Y. enterocolitica O9-infected ones; this assay simply and specifically diagnoses brucellosis. To validate the method in the field and to test the effectiveness of the vaccination program in Mongolia, a serological survey of brucellosis in nomadic animal husbandry in Mongolia was performed in 2010 and 2011. In this study had been determined an animal brucellosis prevalence in Arkhangai and Khovd aimag. The result showed that 1.25% and 0.4% of cattle and 0.04 % and 0.01% of small ruminants were positive for brucellosis in Arkhangai and Khovd aimag respectively.These results showed that B.abortus 159 N5R can be used as an alternative vaccine against bovine brucellosis.

  5. Bone scintigraphy in two cases of chronic brucellosis

    International Nuclear Information System (INIS)

    As shown in the case reports, bone scintigraphy plays an important part considering the diagnosis of chronic brucellosis, an infectious disease which occurs rarely in Germany. To establish the diagnosis knowledge of symptoms and signs of the disease is necessary. Chronic brucellosis may occur in each organ, ionvolving especially bones and joints. The disease may manifest as spondilytis (especially of the lumbar spine) or arthritis of large joints, sacroiliacal joints or costotransverse joints. Chronic brucellosis has to be considered if a bone scan reveals a typical pattern even without a typical history. (orig.)

  6. Cattle producers' economic incentives for preventing bovine brucellosis under uncertainty.

    2012-12-01

    Cattle in the Greater Yellowstone Ecosystem occasionally contract bovine brucellosis from free-ranging elk and bison. Cattle producers use a variety of brucellosis prevention activities to reduce their herds' risk of contracting brucellosis, such as: (1) having state agency personnel haze elk off private land, (2) fencing haystacks, (3) administering adult booster vaccination, (4) spaying heifers, (5) altering the winter-feeding schedule of cattle, (6) hiring riders to prevent cattle-elk commingling, and (7) delaying grazing on high-risk allotments. Their brucellosis prevention decisions are complicated, however, by several sources of uncertainty, including the following: a cattle herd's baseline risk of contracting brucellosis, the inherent randomness of brucellosis outbreaks, the cost of implementing prevention activities, and the activities' effectiveness. This study eliminates one source of uncertainty by estimating the cost of implementing brucellosis prevention activities on a representative cow/calf-long yearling operation in the southern GYE. It then reports the minimum level of effectiveness each prevention activity must achieve to justify investment by a risk-neutral producer. Individual producers face different levels of baseline risk, however, and the US government's brucellosis-response policy is constantly evolving. We therefore estimate breakeven levels of effectiveness for a range of baseline risks and government policies. Producers, animal health experts, and policymakers can use this study's results to determine which brucellosis prevention activities are unlikely to generate sufficient expected benefits to cover their cost of implementation. Results also demonstrate the influence of government policy on producers' incentives to prevent brucellosis. Policies that increase the magnitude of economic loss a producer incurs when their herd contracts brucellosis subsequently decrease prevention activities' breakeven levels of effectiveness, and

    Studies on brucellosis were carried out to elucidate the epidemiology of the disease in Isfahan province, where Brucella melitensis is highly prevalent in animals and man. A positive milk ring test of 32% and 23% was found in unvaccinated goats and sheep respectively. Card and tube agglutination tests showed an infection rate of about 12% in sheep and goats and 42% in cattle. B. melitensis was isolated from 8% of 677 samples of fresh cheese examined.Of 1526 clinically suspected human cases, 476 showed laboratory evidence of brucellosis. Of these patients, 291 cases were from urban and 185 cases from rural areas. Cases from urban and rural areas were seen principally in the younger age groups. The median age of infection was 19.7 in urban and 15.7 in rural patients respectively. The infection was encountered mainly from April to August. This correlates with animal parturition and the greatest amount of sheep and goat milk production, which is introduced to the local market as fresh cheese. Raw dairy product consumption is the most probable way of Brucella transmission in urban patients. In rural areas, both dairy product consumption and contact with animals are sources of infection.

    Brucellosis is an overlooked infection of widespread geographic distribution. This disease is rarely evoked when assessing unexplained pediatric fever, and only 20-30 cases (children and adults) are confirmed per year. Risk factors for contracting brucellosis are exposure to bodily fluids and consumption of unpasteurized dairy products from infected animals. Most cases of brucellosis are associated with traveling to or importing contaminated goods from endemic areas. Here, we report a case of brucellosis in a 16-month-old patient hospitalized for an acute febrile illness in a French general pediatric ward. An antibiotic regimen of rifampicin and co-trimoxazole given over 6 weeks led to successful cure without relapse. The child had eaten a cake made from unpasteurized goat's milk and imported from Oran, a region in Algeria. His mother had consumed the same cake and was hospitalized for brucellosis 15 days later. Clinicians should suspect brucellosis when encountering febrile patients who have traveled to endemic areas, been exposed to body fluids or products of abortion of farm animals, or consumed unpasteurized products.

    Our initial study of the USDA/TAHC Brucellosis Indemnity Program in Texas has shown that both the efficiency and rate of claim payments can be increased by the application of present day computer technologies. Two main factors contribute to these increases: the number of discrepancies that are caused by poor penmanship, transposition of numbers, and other human errors can be monitored and minimized; and the documented information can be indexed, sorted, and searched faster, more efficiently, and without human error. The overall flow of documentation that is used to control the movement of infected or exposed animals through commerce should be studied. A new system should be designed that fully utilizes present day computer and electronic technologies.

    Brucellosis is a highly zoonotic disease that affects animals and human beings. Brucella suis is the etiological agent of porcine brucellosis and one of the major human brucellosis pathogens. Laboratory diagnosis of porcine brucellosis mainly relies on serological tests, and it has been widely demonstrated that serological assays based on the detection of anti O-polysaccharide antibodies are the most sensitive tests. Here, we validate a recombinant glycoprotein antigen, an N-formylperosamine O-polysaccharide-protein conjugate (OAg-AcrA), for diagnosis of porcine brucellosis. An indirect immunoassay based on the detection of anti-O-polysaccharide IgG antibodies was developed coupling OAg-AcrA to enzyme-linked immunosorbent assay plates (glyco-iELISA). To validate the assay, 563 serum samples obtained from experimentally infected and immunized pigs, as well as animals naturally infected with B. suis biovar 1 or 2, were tested. A receiver operating characteristic (ROC) analysis was performed, and based on this analysis, the optimum cutoff value was 0.56 (relative reactivity), which resulted in a diagnostic sensitivity and specificity of 100% and 99.7%, respectively. A cutoff value of 0.78 resulted in a test sensitivity of 98.4% and a test specificity of 100%. Overall, our results demonstrate that the glyco-iELISA is highly accurate for diagnosis of porcine brucellosis, improving the diagnostic performance of current serological tests. The recombinant glycoprotein OAg-AcrA can be produced in large homogeneous batches in a standardized way, making it an ideal candidate for further validation as a universal antigen for diagnosis of "smooth" brucellosis in animals and humans.

    We developed a dynamic model of livestock-to-human brucellosis transmission in Mongolia. The compartmental model considers transmission within sheep and cattle populations and the transmission to humans as additive components. The model was fitted to demographic and seroprevalence data (Rose Bengal test) from livestock and annually reported new human brucellosis cases in Mongolia for 1991-1999 prior to the onset of a mass livestock-vaccination campaign (S19 Brucella abortus for cattle and Rev 1 Brucella melitensis for sheep and goat). The vaccination effect was fitted to livestock- and human-brucellosis data from the first 3 years of the vaccination campaign (2000-2002). Parameters were optimized on the basis of the goodness-of-fit (assessed by the deviance). The simultaneously fitted sheep-human and cattle-human contact rates show that 90% of human brucellosis was small-ruminant derived. Average effective reproductive ratios for the year 1999 were 1.2 for sheep and 1.7 for cattle. PMID:15899298

    Brucellosis is a zoonotic infection, which is still a major public health concern worldwide. Common clinical findings are usually nonspecific involving fever, arthralgia, myalgia, weakness and malaise. Since none of the symptoms of brucellosis is pathognomonic, it may have a similar course with various multisystemic diseases. In terms of focal involvement, sacroiliitis is the most common musculoskeletal manifestation in adult patients, while it is quite rare in pediatric patients. Blood culture is the gold standard in the diagnosis of brucellosis. In the absence of culture facilities, the diagnosis traditionally relies on serologic testing with a variety of agglutination tests such as the Rose Bengal test and the serum agglutination test. However, these agglutination tests are accompanied by frequent false negative results such as seen in prozone phenomenon, which may lead to diagnostic delays. In this article we present a rarely encountered pediatric brucellosis patient who had sacroiliitis-spondylitis, which are rarely reported in children, and exhibited prozone phenomenon in agglutination tests.

    Full Text Available Brucellosis is considered to be one of the most widespread zoonoses in the world. According to OIE, it is the second most important zoonotic disease in the world after rabies. The disease affects cattle, swine, sheep, goats, camels and dogs. It may also infect other ruminants and marine mammals. The disease is manifested by late term abortions, weak calves, still births, infertility and characteristic lesions are primarily placentitis, epididymitis and orchitis. The organism is excreted in uterine discharges and milk. The disease is economically important, is one of the most devastating transboundary animal diseases and also a major trade barrier. Although not yet reported, some species of Brucella (e.g., B. abortus are zoonotic and could be used as bioweapons. Brucellosis has a considerable impact on animal and human health, as well as wide socio-economic impacts, especially in countries in which rural income relies largely on livestock breeding and dairy products. Considering the poor health infrastructure and manpower in rural areas, the focus should be on preventive measures coupled with strengthening the curative health care services for early diagnosis and treatment. The incidence of brucellosis is increasing particularly in large dairy herds in Pakistan. Several studies have been conducted using sero-diagnostic techniques to determine the prevalence of brucellosis in different provinces, districts and livestock farms in government and private sector.

    The diagnostic value of enzyme-linked immunosorbent assay (ELISA) was evaluated when blood specimens of 92 patients suspected of brucellosis underwent the ELISA (IgM and IgG), standard tube agglutination (SAT), and 2-mercaptoethanol (2-ME) tests and blood cultures; 38 sera from non-brucellosis patients and 34 sera from blood donors were also subjected to ELISA, SAT, and 2-ME tests. SAT was able to pinpoint only 23 (25%), whereas ELISA confirmed the etiology in 56 (60.9%; P < 0.001) patients with brucellosis, including 31 culture-confirmed cases. The sensitivity and specificity of ELISA were 100% and 71.31%, respectively. Because they were confirmed by ELISA, the diagnosis could never be excluded with SAT in 33 cases. ELISA has been found to be more sensitive in acute (28% higher sensitivity; P < 0.02) and chronic (55% higher sensitivity; P < 0.01) cases. For accurate diagnosis in suspected brucellosis cases detection, we recommend both ELISA IgM and IgG tests. ELISA IgG and 2-ME tests seem to be promising tools in judging prognosis. PMID:20682874

    Bovine brucellosis is a zoonotic disease spread worldwide. The infection in cattle is predominantly caused by Brucella abortus and is usually detected in pregnant females through abortions. The disease is endemic in Argentina; however, infection in humans is underestimated and often not reported. The prevalence of bovine brucellosis in countries bordering Argentina is quite variable: 0.04% in Uruguay, 10.20% in the north and 0.06% in the south of Brazil, 0.2% in Chile, 3.15% in Paraguay and 2.27% in Bolivia. In 1999, the Argentine National Control and Eradication Program was implemented. Its strategies include identification of vaccinated animals, compulsory vaccination with B. abortus S19 of 100% of 3- to 8-month-old females, negative serological tests before animal movements and categorization of farms in terms of their brucellosis status. The epidemiological surveillance in milk is performed through the milk ring test and the indirect ELISA. The result of a national brucellosis survey performed in 2004 indicates that 12.4% (95% CI: 10.89-14.0) of Argentine beef farms are seropositive to Brucella and that the apparent prevalence in cattle is 2.10% (95% CI: 1.90-2.40). The official serological diagnostic tests are as follows: buffered plate antigen test, as screening, serum agglutination test, 2-mercaptoethanol and fluorescence polarization assay, competitive ELISA, as confirmatory tests, and complement fixation test, as definitive test. Santa Fe and a district in Córdoba have 'Outstanding Plans'. Tierra del Fuego is a 'Zone free from bovine brucellosis'. One question arising when studying the Argentine situation is why the disease remains endemic if good regulations exist to control and eradicate it. In future, some different aspects might be evaluated to understand it, and further studies should be performed to prioritize, select and refine control strategies. PMID:23046031

    The gram-negative bacteria of the genus Brucella are facultative intracellular parasites that cause brucellosis, a world wide-distributed zoonotic disease that represents a serious problem for animal and human health. There is no human-to-human contagion and, since there is no human vaccine, animal vaccination is essential to control brucellosis. However, current vaccines (all developed empirically) do not provide 100% protection and are infectious in humans. Attempts to generate new vaccines by obtaining mutants lacking the lipopolysaccharide O-polysaccharide, in purine metabolism or in Brucella type IV secretion system have not been successful. Here we propose a new approach to develop brucellosis vaccines based on the concept that Brucella surface molecules evade efficient detection by innate immunity, thus delaying protective Th1 responses and opening a time window to reach sheltered intracellular compartments. We showed recently that a branch of the core oligosaccharide section of Brucella lipopolysaccharide hampers recognition by TLR4-MD2. Mutation of glycosyltransferase WadC, involved in the synthesis of this branch, results in a lipopolysaccharide that, while keeping the O-polysaccharide essential for optimal protection, shows a truncated core, is more efficiently recognized by MD2 and triggers an increased cytokine response. In keeping with this, the wadC mutant is attenuated in dendritic cells and mice. In the mouse model of brucellosis vaccines, the Brucella abortus wadC mutant conferred protection similar to that provided by S19, the best cattle vaccine available. The properties of the wadC mutant provide the proof of concept for this new approach and open the way for more effective brucellosis vaccines. PMID:23219811

    Full Text Available Brucellosis remains as an endemic infection of humans in many parts of the world; Latin America, Asia including Middle East and Mediterranean region including Turkey. Neonatal brucellosis is very rare and clinical manifestations as well as transmission route are not well-defined. The neonate can be either infected transplacentally, or by ingestion of mother’s secretions and blood during delivery, or by ingestion of breast milk. Here, we present two cases with two different transmission route and clinical findings. First case is a premature infant born after 31 weeks of gestation and hospitalized for respiratory distress in addition to hepatosplenomegaly and leukocytosis. Brucella species were isolated from the initial blood culture obtained just after birth. Clinical and laboratory findings improved with decreased ventilatory support after replacement of antibiotherapy with trimethoprim-sulfamethoxazole (TMP-SMX and rifampicin. Second case was a 28 days old, term infant. Her sibling was diagnosed as brucellosis and during evaluation of the family members, her mother was found to have brucellosis just before delivery. Initial evaluation of the baby after birth was totally normal. Beside medical advice, she was breastfed and in the 4th week of life she was found to have leucopenia and neutropenia, and brucella tube agglutination test turned to be positive. After antibiotherapy, laboratory findings were normalized. Breastfeeding was ceased during the treatment periods of both mothers. Both families were from rural regions of Turkey, who were using unpasteurized dairy products. Both patients were treated with TMP-SMX and rifampicin for 6 weeks without any complication. Brucella spp must be sought as a causative agent in the differential diagnosis of intrauterine and neonatal infections in endemic countries. Family members of patients from rural areas of the country must be questioned about traditional food consumption, as findings of neonatal

    Full Text Available Studies have been done on public health significance of brucellosis using serology with little or no emphasis to risk factors. Therefore, this study was designed to investigate seroprevalence of brucellosis and assess epidemiological variables associated with human brucellosis. After obtaining verbal consent, 241 peripheral blood samples were collected from occupationally exposed groups with and without pyrexia of unknown origin. A structured questionnaire was prepared to gather risk factors, such as occupation, age, sex, history of consuming raw milk and other unpasteurised dairy products, direct contact with domestic animals, general knowledge about the route of transmission and awareness level. Purposive sampling was used to select the key informants. All serum samples were first screened by Rose Bengal Plate Test (RBPT and further analysed by Standard Tube Agglutination Test (STAT. The results revealed that 24.5% were positive by RBPT and diagnosis was established in 26.6% using STAT with a titre range between 80 and 1,280 IU/ml. Among occupational groups, prevalence was 17.8% in veterinarians and pharmacists but was not statistically significant. The most common clinical symptoms at presentation were fever, headache, back pain, arthralgia and myalgia. No female reactor was found and the mean age and standard deviation of seropositive patients was 34.69±10.97 years. Risk factors such as residence in rural area, participation in vaccination of animals and eating during working hours were significantly associated (P<0.05 with brucellosis by univariate and multivariate analysis. In conclusion, to deal with occupation-related disease like brucellosis, awareness on risk factors must be part of extension education campaign. Besides, regular surveillance of the disease needs to be integrated into control and prevention programme at a local and national level.

    Full Text Available The dissemination of cattle brucellosis in Zhejiang province of China can be attributed to the transport of cattle between cities within the province. In this paper,an n-patch dynamical model is proposed to study the effect of cattle dispersal on brucellosis spread. Theoretically,we analyze the dynamical behavior of the muti-patch model. For the 2-patch submodel,sensitivity analyses of the basic reproduction number R0 and the number of the infectious cattle in term of model parameters are carried out. By numerical analysis,it is obtained that the dispersal of susceptible cattle between patches and the centralization of infected cattle to the large scale patch can alleviate the epidemic and are in favor of the control of disease in the whole region.

    Background Brucellosis can mimic various multisytem diseases,showing wide clinical polymorphism that frequently leads to misdiagnosis and treatment delay,further increasing the complication rates.In this study,we aimed to examine bone marrow biopsy findings in brucellosis cases presenting with hematologic abnormalities.Methods Forty-eight brucellosis cases were prospectively investigated.Complaints and physical examination findings of patients were recorded.Patients' complete blood count,routine biochemical tests,erythrocyte sedimentation rate,C-reactive protein and serological screenings were performed.Bone marrow biopsy and aspiration was performed in patients with cytopenia,for bone marrow examination and brucella culture,in accordance with the standard procedures from spina iliaca posterior superior region of pelvic bone.Results Of the 48 patients,35 (73%) were female and 13 (27%) were male.Mean age was (34.8±15.4) years (age range:15-70 years).Anemia,leukopenia,thrombocytopenia and pancytopenia were found in 39 (81%),28 (58%),22 (46%) and 10 patients (21%),respectively.In the examination of bone marrow,hypercellularity was found In 35 (73%) patients.Increased megacariocytic,erythroid and granulocytic series were found in 28 (58%),15 (31%) and 5 (10%) patients,respectively.In addition,hemophagocytosis was observed in 15 (31%) patients,granuloma observed in 12 (25%) and increased eosinophil and plasma cells observed in 9 (19%) patients.Conclusion According to the results of our series,hemophagocytosis,microgranuloma formation and hypersplenism may be responsible for hematologic complications of brucellosis.

  7. Field trial of brucellosis competitive enzyme linked immunosorbent assay (ELISA)

    International Nuclear Information System (INIS)

    The purpose of this study was to compare the diagnostic performance characteristics of the competitive (C) ELISA for the diagnosis of bovine brucellosis and the differentiation of Brucella infected from Brucella vaccinated cattle to the indirect (I) ELISA and the conventional serological techniques used in Argentina. The diagnostic specificity and relative sensibility of ELISA was comparable to CFT and 2ME, which are the official complementary tests in Argentina. Besides, C-ELISA showed the best performancein analysing vaccinated animals. The application of the ELISA test is largely feasible because of its reproducibility and easy standardization. In addition, although CFT has a great performance, its application is cumbersom; the 2ME test lasted for 48 h and is toxic. Both the C-ELISA, using MAb M84, and the I-ELISA, using MAb M23, have been demonstrated to have the best performance. Owing to our field conditions (brucellosis prevalence and mandatory vaccination of female calves) the competitive ELISA should be applied as a complement of the official screening tests such as BP. These results suggest that the ELISA test would be very useful in contributing to the control and eradication programme of bovine brucellosis in Argentina

    2016-03-01

    Severe thrombocytopenia with bleeding is rarely reported in children with brucellosis, and recurrent epistaxis is extremely rare. Brucellosis with hemorrhage should be differentiated from viral hemorrhagic fever, malignancy, and other blood disorders. Bone marrow aspiration (BMA) is mandatory to differentiate from other blood diseases. An 8-year-old boy was admitted with recurrent epistaxis, petechiae and purpura on face and extremities and bleeding from the gums. During the hospitalization, he was febrile and complained of muscle pain. Leukopenias associated with thrombocytopenia were observed. BMA showed to be normal. Among the multiple tests requested, only serum agglutination test (SAT) and 2-MercaptoEthanol test (2-ME) were positive. He was treated with Intravenous immunoglobulin (IVIG) associated with co-trimoxazole and rifampin. Finally, fever subsided, and he was discharged with good condition and normal platelet count. Brucellosis should be a differential diagnosis in patients with fever and bleeding disorders and a history of consumption of unpasteurized dairy, in endemic areas. PMID:27107528

    This retrospective study included seven paediatric cases aged from 4 to 14 (10.2±3.4) years with pathologically proved haemophagocytic lymphohistiocytosis from a single institution during 2009 and 2013. Over this time period, 496 patients with brucellosis were diagnosed. None of the patients (3 boys and 4 girls) had a history of any haematologic disorder. All patients had an anamnesis for recently consumed unpasteurised homemade dairy products or had a contact history with sheep and/or cows. The diagnosis of brucellosis was confirmed by standard tube agglutination test in all patients; titres were 1: 1280 in seven patients. Blood culture was positive for Brucella melitensis in three patients (42%). Bone marrow cultures were positive for B. melitensis in four patients (57%). Fever was present in all patients (100%) with haemophagocytic lymphohistiocytosis. The other most common symptoms were malaise, myalgia, anorexia, sweating and weight loss. In addition, sweating was observed in five patients, and lymphadenopathy, petechiae, and weight loss were observed in one patient. Hepatomegaly, splenomegaly, and hepatosplenomegaly were found in four (57%), six (85%) and four (57%), patients, respectively. Haemophagocytosis was documented in bone marrow examinations of all children except in two cases. All patients recovered completely, and their peripheral blood counts returned to normal by 2 to 4 weeks after antibiotic treatment of brucellosis. PMID:27367321

  10. Brucellosis: Development and success using ELISAs for diagnosis

    International Nuclear Information System (INIS)

    Brucellosis is a highly infectious disease of a substantial number of animal species. Because of its pathogenicity to humans, the cost and time involved, classical diagnosis by isolation of the causative microorganism is not commonly used for diagnosis of individual animals. Presumptive diagnosis has been made for about 100 years by using serological tests. Initially, a slow agglutination test was developed and later modified to increase the sensitivity and to decrease the time. Complement fixation and gel diffusion tests were also developed and, in some cases, widely used. The development of primary binding assays, in particular, enzyme immunoassays, has provided tools for diagnosis that are more accurate than conventional serological tests. The enzyme immunoassays, the indirect and competitive formats, have different uses but are both potent additions to the diagnosis of brucellosis in that they may be used for rapid and accurate assessment of antibody in milk and serum in the absence of interference by antibodies resulting from vaccination. Another type of primary binding assay, a fluorescence polarization assay, was also developed for the diagnosis of brucellosis. This assay, which is a homogeneous format, has the added advantages of being simple to perform, very rapid, potentially inexpensive and capable of being performed outside the laboratory. (author)

    Full Text Available Purpose. Acute scrotal pain as the first symptom of brucellosis is rarely observed. We aimed to evaluate the data of male patients with brucellosis and epididymoorchitis as the initial diagnosis. Material and Methods. The data of seven patients presented with testicular pain, hyperemia, swelling, and increased fever were reviewed. Concomitant focal diseases as well as clinical, laboratory, and radiological findings were retrospectively evaluated. Results. The mean age of the patients was 22.28 ± 7.78 (16–35 years. All patients presented with scrotal pain, swelling, and increased sweating. Additional findings included fever, asthenia, arthralgia, dysuria, shiver and rash, weight loss, and vomiting in 6, 5, 4, 4, 3, 2, and 1 patient, respectively. In all of 7 patients, the agglutination tests of Rose-Bengal and Wright were positive. Coombs test was positive only in 3 patients. The patients underwent antibiotic and conservative treatment. No relapse was observed following the treatment. Conclusion. In endemic regions, epididymoorchitis caused by brucellosis should be considered in the differential diagnosis of patients presenting with acute scrotal pain. Clinical and serological findings are sufficient for the diagnosis. Conservative management combined with antibiotic therapy is adequate for managing brucellar epididymoorchitis.

    Full Text Available Infection with Brucella spp. continues to pose a human health risk globally despite strides in eradicating the disease from domestic animals. Brucellosis has been an emerging disease since the discovery of Brucella melitensis by Sir David Bruce in 1887. Although many countries have eradicated B. abortus from cattle, in some areas B. melitensis and B. suis have emerged as causes of this infection in cattle, leading to human infections. Currently B. melitensis remains the principal cause of human brucellosis worldwide including India. The recent isolation of distinct strains of Brucella from marine mammals as well as humans is an indicator of an emerging zoonotic disease. Brucellosis in endemic and non-endemic regions remains a diagnostic puzzle due to misleading non-specific manifestations and increasing unusual presentations. Fewer than 10% of human cases of brucellosis may be clinically recognized and treated or reported. Routine serological surveillance is not practiced even in Brucella - endemic countries and we suggest that this should be a part of laboratory testing coupled with a high index of clinical suspicion to improve the level of case detection. The screening of family members of index cases of acute brucellosis in an endemic area should be undertaken to pick up additional unrecognised cases. Rapid and reliable, sensitive and specific, easy to perform and automated detection systems for Brucella spp. are urgently needed to allow early diagnosis and adequate antibiotic therapy in time to decrease morbidity / mortality. The history of travel to endemic countries along with exposure to animals and exotic foods are usually critical to making the clinical diagnosis. Laboratory testing is indispensable for diagnosis. Therefore alertness of clinician and close collaboration with microbiologist are essential even in endemic areas to correctly diagnose and treat this protean human infection.

    Full Text Available Purpose: Brucellosis is a systemic disease that can affect many organs and tissues. Musculoskeletal system is one of the most commonly affected systems. Disease may present itself with sacroiliitis, peripheral arthritis, spondylitis, paraspinal abscess, bursitis or osteomyelitis. The objective of the present study was to determine the frequency, types and clinical features of osteoarticular involvement among cases with brucellosis in Konya city and to establish the differences between patients with and without osteoarticular involvement. Material and Methods: Three hundred and sixteen patients with Brucellosis who presented between June 2003 and June 2014 were included in the study. Brucellosis was diagnosed by positive Brucella Standard Agglutination Test ( and #61619;1/160 titer and/or growth of Brucella spp. in blood culture in addition to the presence of clinical signs and findings. Diagnosis of osteoarticular system complications was established by physical examination and radiological findings obtained by diagnostic imaging tools. Magnetic resonance images of the thoracic, lumbar or sacral vertebrae were acquired in patients with back pain, low back pain and sacro-iliac joint pain. Results: Osteoarticular involvement was noted in 129 patients (40.8% (females: 52% and males: 48%. The most common route of transmission was employment in farming and/or consumption of un-pasteurized milk or dairy products, especially fresh cheese, in 97 (75% cases. Mean age was 46 and #61617;18 years. Sacroiliitis was the most frequent osteoarticular involvement (n: 68, 52.7%, 70.5% of which were bilateral.

  19. Seroprevalence of brucellosis and associated hemato-biochemical changes in pakistani horses

    International Nuclear Information System (INIS)

    The aim of this study was to determine the seroprevalence and hemato-biochemical manifestations of brucellosis in horses. Serum samples were screened for Brucella antibodies by Rose Bengal plate test (RBPT) and serum agglutination test (SAT). Blood samples were evaluated for hemato-biochemical parameters following standard procedures. Results indicated seroprevalence of brucellosis 20.13 and 16.23% in horses by RBPT and SAT, respectively. Brucellosis does not lead to any significant change in hematological and biochemical parameters in relation to age, sex, body condition and lactation except few parameters. The values of erythrocyte sedimentation rate, neutrophil, basophil and alkaline phosphatase significantly decreased in brucellosis positive animals as compared to healthy animals whereas lymphocytes and alanine aminotransferase were in opposite order. It was concluded from the results that prevalence of brucellosis in horse population is of concern; therefore, control measures should be opted so that its zoonotic threat is curtailed. (author)

    Brucellosis is a zoonosis caused by Brucella ,with an acute or chronic clinical infection .Clinical manifestations of brucellosis are various or atypical ,and it is easily misdiagnosed and miss-diagnosed .The case we have reported had an onset of fever and abdominal pain ,associated with arthralgia ,headache and rashes during the course , and was initially misdiagnosed as “acute cholangitis , associated with biliary pancreatitis” . According to epidemiologic survey , radiological evidence , as well as blood culture and agglutination test showing Brucella positive ,the diagnosis of brucellosis associated with splenic infarction and multi-systemic involvement including lungs , skin and brain was made . After regular anti-brucellosis treatment , the patient’s symptoms were significantly improved . Brucellosis associated with splenic infarction is rare ,which is possibly due to vasculitis resulting from Brucella infection .

  1. A Case of Brucellosis Associated with Histiocytic Necrotizing Lymphadenitis: A Diagnostic Pitfall.

    2013-10-01

    Full Text Available Human cases of brucellosis are rare in the United States and difficult to diagnose. We report a case of a young female who underwent a diagnostic investigation of fever of unknown origin, which included a lymph node biopsy. The biopsy was consistent with Kikuchi’s Disease, or histiocytic necrotizing lymphadenitis, an entity where the major differential diagnosis is systemic lupus erythematosus. Interestingly, serologic studies supported the diagnosis of brucellosis. Brucellosis has rarely been associated with histiocytic necrotizing lymphadenitis. This association has never been reported in the United States, thus suggesting that brucellosis should be considered in the differential for histiocytic necrotizing lymphadenitis, along with lupus-like autoimmune disease. As the prognosis and treatment of histiocytic necrotizing lymphadenitis, brucellosis, and systemic lupus erythematosus are distinct, it is important to differentiate these entities.

    A total of 5726 blood specimens (from children aged 14 years and younger) were studied for the serological evidence of brucellosis. Ninety-three (1.6 per cent) showed diagnostic agglutinin titres with a geometric mean titre of 403 (SD +/- 547). Forty-three (59.7 per cent) blood specimens yielded the growth of Brucella melitensis. Thirty-nine patients (41.93 per cent) were shepherds, who constituted the major occupational group affected in the present series. More than 60 per cent of the patients had a history of both consumption of fresh goat's milk and close animal contact. The habit of consuming fresh goat's milk to obtain relief from chronic ailments was noted in nine patients. Seventy-three (78.49 per cent) were males and 20 (21.51 per cent) were females, with a male to female ratio of 3:1. The disease occurred mainly in the school age group (mean age 10.3 years). All the patients had an acute history of less than 2 months. Forty-nine (52.68 per cent) patients presented with persistent fever, 19 (20.43 per cent) with joint pain, and the rest with a combination of fever and joint pain with and without low backache, fever being the commonest complaint. One case presented with involuntary movements of limbs alone and the other with burning feet only. Pityriasis alba was the consistent physical finding, with fever in the majority of the patients. The major joint found to be involved was the knee (52.77 per cent). The synovial fluid obtained from the knee joint of five patients demonstrated Brucella agglutinins and also three grew B. melitensis. Eight patients presented with complications that included skin lesions (3), carditis (2), neurobrucellosis such as chorea (1), peripheral neuritis (1), and meningitis (1). Brucella melitensis biotype 1 was successfully isolated from the papular eruption of one out of three cases who presented with skin lesions. To our knowledge this is the fourth confirmed isolation of B. melitensis from skin lesions with brucellosis

    Full Text Available This research aims to conduct a descriptive study of the occurrence of human brucellosis in Colombia between 2000 and 2012, and, based on previous studies, to determine the prevalence and incidence of the disease, and the limitations for its timely diagnosis and recognition by the Colombian labor system. The research consisted of searching for and analyzing articles on human brucellosis published between 2000 and 2012 in Colombia. It included a phase of information gathering and unstructured interviews with representatives of brucellosis control programs and experienced professionals. We analyzed 17 studies of human brucellosis cases in personnel at risk in slaughterhouses, retailers and vaccinators for animal brucellosis programs: 10 of them reported prevalences between 0.14% and 10.4%, and seven evidenced seropositivity. Information revealed the limitations of the diagnosis, and it demonstrated the little knowledge of the medical community about this disease. In Colombia, there is no clear policy regarding this occupational zoonosis. Brucellosis is mentioned only in Decree 2566 of 2009, in which the new table of occupational diseases is established. The paper concludes that human brucellosis in Colombia is an underdiagnosed, and therefore underreported, disease since there is no mandatory reporting system on the subject.

    Full Text Available Brucellosis infection is a multisystem disease, with a broad spectrum of symptoms. We investigated the existence of clusters of infected patients according to their clinical presentation. Using national surveillance data from the Electronic-Integrated Disease Surveillance System, we applied a latent class cluster (LCC analysis on symptoms to determine clusters of brucellosis cases. A total of 454 cases reported between July 2011 and July 2013 were analyzed. LCC identified a two-cluster model and the Vuong-Lo-Mendell-Rubin likelihood ratio supported the cluster model. Brucellosis cases in the second cluster (19% reported higher percentages of poly-lymphadenopathy, hepatomegaly, arthritis, myositis, and neuritis and changes in liver function tests compared to cases of the first cluster. Patients in the second cluster had a severe brucellosis disease course and were associated with longer delay in seeking medical attention. Moreover, most of them were from Beylagan, a region focused on sheep and goat livestock production in south-central Azerbaijan. Patients in cluster 2 accounted for one-quarter of brucellosis cases and had a more severe clinical presentation. Delay in seeking medical care may explain severe illness. Future work needs to determine the factors that influence brucellosis case seeking and identify brucellosis species, particularly among cases from Beylagan.

This bacterium generally will transfer to human from contact with contaminated animals or the consumption of cattle production such as unpasteurized dairy (raw milk, soft cheese, cream or even via breathe can transfer to human. But the transfer of infection from person to person is very infrequent.Of course there is some evidence of transfer in a bone marrow transplanting. The most prevalent clinical symptoms of this disease are fever, night sweat, asthenia and anorexia (2.Naturally this infection involved different systems and organs in human body and the one of most major part of body can be mentioned to nervous system, muscuskeletal and also some organs like joints, heart and liver.Diagnosis of this infection can be made by some various laboratory tests like SAT, 2ME.

    Full Text Available Abstract Introduction Myositis is a rare bacterial muscle infection. Involvement of the piriformis muscle has been rarely reported in the literature. In this report we describe a case of piriformis myositis due to Brucella melitensis, which to the best of our knowledge is the first such case presented in the literature. Case presentation We report the case of a 19-year-old Caucasian man who presented to our institution with fever and right hip pain. Brucellosis was suspected, but the clinical suspicion was for spondylodiscitis. A pelvic magnetic resonance imaging scan allowed prompt diagnosis of inflammatory involvement of the right piriformis muscle. Blood culture results were positive for B. melitensis. Our patient was treated with antibiotics, and follow-up magnetic resonance imaging scans showed resolution of the inflammation. Conclusion Brucellosis can present as piriformis myositis. The clinical diagnosis of piriformis myositis is difficult, as it can mimic other common entities such as referred back pain from spondylodiscitis. Magnetic resonance imaging is the method of choice for establishing the diagnosis in the early stages of the disease, as late diagnosis can lead to abscess formation and the need for drainage.

    Sera from 2,630 apparently normal adult camels (Camelus dromedarius) raised in central Saudi Arabia (Riyadh and Al-Kharj cities) were examined serologically by the Rose Bengal and standard United States of America Brucella plate agglutination tests. The overall seroprevalence of brucellosis in the restricted populations of tested camels was 8%. The seroprevalence of brucellosis among camels raised in small numbers in the backyards of 24 houses in Riyadh and those intensively raised on one large camel farm near Al-Kharj were 4.3% and 8.6% respectively. Fresh milk samples from 100 brucellosis seropositive camels from Riyadh and Al-Kharj were cultured on Brucella-selective media. Brucella melitensis biovars 1 and 2 were isolated and identified from 26 camels. Epidemiologically, brucellosis in camels in central Saudi Arabia appeared to be connected with B. melitensis infection of sheep and goats, and also represents a serious public health risk.

    Brucellosis is a zoonotic disease common in developing countries. Vascular complications, including arterial and venous, associated with Brucella infection have rarely been reported. A case of deep venous thrombosis (DVT) developing after a diagnosis of acute brucellosis in a young milkman is presented. A 26-year-old man presented with pain in the right leg. The patient's medical history included a diagnosis of brucellosis in our hospital where he had presented with complaints of weakness and fever. Peripheral venous Doppler ultrasound showed DVT, and the patient was treated with anticoagulants. The patient was discharged with warfarin therapy and anti-brucellosis treatment. Although rare, some infectious agents may cause vascular pathologies. Patients presenting with symptoms of DVT or similar vascular pathologies should be assessed for infectious agents, particularly in those coming from Brucella-endemic areas.

    Full Text Available Abstract Background Brucellosis is known to cause debilitating conditions if not promptly treated. In some rural areas of Tanzania however, practitioners give evidence of seeing brucellosis cases with symptoms of long duration. The purpose of this study was to establish health-seeking behaviour of human brucellosis cases in rural Tanzania and explore the most feasible ways to improve it. Methods This was designed as a longitudinal study. Socio-demographic, clinical and laboratory data were collected from patients who reported to selected hospitals in rural northern Tanzania between June 2002 and April 2003. All patients with conditions suspicious of brucellosis on the basis of preliminary clinical examination and history were enrolled into the study as brucellosis suspects. Blood samples were taken and tested for brucellosis using the Rose-Bengal Plate Test (RBPT and other agglutination tests available at the health facilities and the competitive ELISA (c-ELISA test at the Veterinary Laboratory Agencies (VLA in the UK. All suspects who tested positive with the c-ELISA test were regarded as brucellosis cases. A follow-up of 49 cases was made to collect data on health-seeking behaviour of human brucellosis cases. Results The majority of cases 87.7% gave a history of going to hospital as the first point of care, 10.2% purchased drugs from a nearby drug shop before going to hospital and 2% went to a local traditional healer first. Brucellosis cases delayed going to hospital with a median delay time of 90 days, and with 20% of the cases presenting to hospitals more than a year after the onset of symptoms. Distance to the hospital, keeping animals and knowledge of brucellosis were significantly associated with patient delay to present to hospital. Conclusion More efforts need to be put on improving the accessibility of health facilities to the rural poor people who succumb to most of the diseases including zoonoses.

    Brucellosis is one of the most widespread zoonotic diseases, with the most frequent complication being osteoarticular changes. The aim of this study was to assess the changes of C-terminal telopeptide of type II collagen (CTX-II) in patients infected with brucellosis. A total of 84 brucellosis patients and 43 volunteers were selected and divided into brucellosis vs. control groups. Serum samples were subjected to serological tests for brucellosis, and CTX-II levels in all samples were measured simultaneously with ELISA. The results showed that serum CTX-II levels in human brucellosis were higher than those of healthy controls, without a statistically significant difference, but serum CTX-II levels in male patients were significantly higher than those of female patients (Pbrucellosis.

  19. Is Wright Test an Appropriate Screening Test for Diagnosis of Brucellosis?

    Directory of Open Access Journals (Sweden)

    Behzad Mohsenpour

    2011-01-01

    Full Text Available Problem statement: Diagnosis of brucellosis is generally based on culture, polymerase chain reaction and serology. The first two methods are not accessible in all parts of world and are expensive. The routine method for diagnosis of brucellosis is considering Wright test as the first screening test; if the results are Wright positive’ Wright would be the next choice otherwise 2ME would be requested. This method of laboratory data collection is not appropriate and it is probable to have some cases of brucellosis missed and in clinical practice we observed that some cases of brucellosis are Wright negative but Coombs’ Wright positive. Approach: In this study we calculated sensitivity, specificity, positive predictive value, negative predictive value and likelihood ratio of Wright and Coombs’ Wright in brucellosis suspected patients. Results: 122 patients suspected to brucellosis were studied. 53.3% were female. Sensitivity and specificity Positive Predictive Values (PPV and Negative Predictive Values (NPV of Wright were 32.5% (CI95%: 22.8-42.3, 96.4% (CI95%: 89.5-100, 96.6% (CI95%: 0.9-100 and 93.1% (CI95%:83.8-100 respectively. Sensitivity, specificity, positive predictive value and negative predictive value for Coombs’ Wright were 97.7% (CI95%: 94.6-100, 100% (CI95%: 100-100, 100% (CI95%: 100-100 and 93.1% (CI95%:83.8-100 respectively. Conclusion: Coombs’ Wright is more sensitive than Wright for diagnosis of brucellosis. Instead of considering Wright, Coombs’ Wright and 2ME (mercaptoethanol tests and interpretation of these three test we can just apply Coombs’ Wright and 2ME to reduce the expenditures and use a more sensitive test for diagnosis of brucellosis.

  4. Magnetic resonance spectroscopy features of normal-appearing white matter in patients with acute brucellosis

    International Nuclear Information System (INIS)

    We aimed to evaluate whether the subtle metabolic cerebral changes are present in normal-appearing white matter on conventional MRI, in patients with acute brucellosis, by using MR spectroscopy (MRS). Sixteen patients with acute brucellosis and 13 healthy control subjects were investigated with conventional MRI and single-voxel MRS. Voxels were placed in normal-appearing parietal white matter (NAPWM). N-Acetyl aspartate (NAA)/creatine (Cr) and choline (Cho)/Cr ratios were calculated. There was no significant difference between the study subjects and the control group in NAA/Cr ratios obtained from NAPWM. However, the Cho/Cr ratios were significantly higher in patients with acute brucellosis compared to controls (p = 0.01). MRS revealed metabolic changes in normal-appearing white matter of patients with brucellosis. Brucellosis may cause subtle cerebral alterations, which may only be discernible with MRS. Increased Cho/Cr ratio possibly represents an initial phase of inflammation and/or demyelination process of brucellosis

    When a pathogen infects a number of different hosts, the process of determining the relative importance of each host species to the persistence of the pathogen is often complex. Removal of a host species is a potential but rarely possible way of discovering the importance of that species to the dynamics of the disease. This study presents the results of a 12-year programme aimed at controlling brucellosis in cattle, sheep and goats and the cascading impacts on brucellosis in a sympatric population of red deer (Cervus elaphus) in the Boumort National Game Reserve (BNGR; NE Spain). From February 1998 to December 2009, local veterinary agencies tested over 36 180 individual blood samples from cattle, 296 482 from sheep and goats and 1047 from red deer in the study area. All seropositive livestock were removed annually. From 2006 to 2009 brucellosis was not detected in cattle and in 2009 only one of 97 red deer tested was found to be positive. The surveillance and removal of positive domestic animals coincided with a significant decrease in the prevalence of brucellosis in red deer. Our results suggest that red deer may not be able to maintain brucellosis in this region independently of cattle, sheep or goats, and that continued efforts to control disease in livestock may lead to the eventual eradication of brucellosis in red deer in the area.

    Full Text Available A study was performed in 2008 to estimate the prevalence of tuberculosis and brucellosis in traditionally reared cattle of Southern Province in Zambia in four districts. The single comparative intradermal tuberculin test (SCITT was used to identify TB reactors, and the Rose Bengal test (RBT, followed by confirmation with competitive enzyme-linked immunosorbent assay (c-ELISA, was used to test for brucellosis. A total of 459 animals were tested for tuberculosis and 395 for brucellosis. The overall prevalence of BTB based on the 4 mm and 3 mm cutoff criteria was 4.8% (95% CI: 2.6–7.0% and 6.3% (95% CI: 3.8–8.8%, respectively. Change in skin thickness on SCITT was influenced by initial skin-fold thickness at the inoculation site, where animals with thinner skin had a tendency to give a larger tuberculin response. Brucellosis seroprevalence was estimated at 20.7% (95% CI: 17.0–24.4%. Comparison between results from RBT and c-ELISA showed good agreement (84.1% and revealed subjectivity in RBT test results. Differences in brucellosis and tuberculosis prevalence across districts were attributed to type of husbandry practices and ecological factors. High prevalence of tuberculosis and brucellosis suggests that control control programmes are necessary for improved cattle productivity and reduced public health risk.

    The aim of this study was to evaluate the clinical, laboratory findings and therapeutic features of patients with brucellosis. The diagnosis was made by clinical findings, automated blood culture, serology (Rose Bengal plate agglutination test, standard tube agglutination (Wright) and immunofluorerescence). The susceptibility of 13 strains was tested in vitro. The base sequence was determined for four strains. Forty-five cases were collected (31 acute and 14 sub-acute). Contamination was digestive in 62%. Symptoms of patients were fever (93%), sweating (82%), arthralgia (78%) and splenomegaly (51%). Elevated erythrocyte sedimentation rate was determined in 80%, leukopenia in 49% and anaemia in 37% of cases. Blood cultures were positives in 39% of cases. The four sequenced strains were identified as Brucella melitensis biovar abortus. Six strains were resistant to sufomethoxazol-trimetoprim (54%). In 93% of cases, the treatment was associated rifampicin and doxycyclin. One patient died. No relapse was reported. PMID:18387752

  13. Evaluation of four immunoassays for diagnosis of brucellosis in Cuba

    International Nuclear Information System (INIS)

    Four immunoassays (two indirect and two competitive ones) were evaluated by samples from areas free of disease, free by vaccination and affected areas using as reference techniques the Bengal Rose Tests, the Antigen in Buffered Plate Tests and the Complement Fixation Reaction Test. The evaluated samples demonstrated that the competitive assays (ELISAC-1 and ELISAC-2) detected less false positives than the indirect ones (ELISAI-1 and ELISAI-2). Of the competitive ELISAS, version 2 presented better sensitivity and specificity results in affected areas for 95% confidence: 80.9 - 96.9% and 97.5 - 99.4% respectively with positive predictive value in the range of 76 to 94% and negative predictive one between 98.1 and 99.7%. It was concluded that this assay can be used for brucellosis control because it gives higher assurance than the other evaluated immunoassays and it can discriminate infected from vaccinated animals.

    Brucellosis is a zoonotic disease causing serious public health problems in countries of the Middle-East and developing countries like India. Neurobrucellosis is one of the devastating complications of this re-emerging zoonosis. The objective of this review was to identify the neurological manifestations of Brucellosis in an Indian population and bring into light the effective modalities used for treating neurobrucellosis. A systematic review of the scientific literature reported in accordance with the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines was conducted. Three databases (PubMed, IndMed, and ScienceDirect) were used to analyze retrospectively case reports of sufficient quality for data extraction (from the last 15 years, 2002-2016), and relevant literature was reviewed. Most of the cases had a definite history of exposure to Brucella through occupational contact with cattle, drinking raw milk, or living near unhygienic abattoir or even trips to epidemic areas outside India. The common presentations include fever, meningitis, brisk deep-tendon reflexes, extensor plantars, sensory deficit usually below the twelfth thoracic vertebral level, weakness of lower limbs, ocular signs of papilledema, and retrobulbar neuritis. The usual systemic findings associated were hepatosplenomegaly and weight-loss. Neurobrucellosis needs to be kept in mind in the differential diagnosis of fever of unknown origin involving neurological symptoms and systemic involvement. Prognosis is good if there is a combination of antibiotics, each with different mechanisms of action given in full dose. Suitable measures for its prevention are also suggested. PMID:27555982

    Full Text Available Background: Because of the difficulty in the diagnosis of brucellosis, particularly in endemic areas, the use of new and feasible diagnostic tests seem to be of great importance for resolving the diagnostic obstacles. We evaluated the usefulness of a new serological test based on an immunocapture-agglutination technique in comparison with ELISA test for serological diagnosis of brucellosis.Methods: A total of 11 patients with brucellosis, who had positive blood cultures for Brucella species, and 47 suspected patients were included in this study. Serum samples collected from these patients were tested by brucellacapt and ELISA and the results were, consequently, compared.Results: In patients with positive blood culture, all the samples gave positive results with brucellacapt test while IgM ELISA, IgG ELISA and (IgG + IgM ELISA tests were positive in 8, 9 and 11 patients, respectively. Out of the 46 suspected patients, (IgG + IgM ELISA, Brucellacapt, IgG ELISA and IgM ELISA were positive in 37, 15, 34 and 37 patients, respectively.The best cut-off point of ELISA-IgG was 10.78 IU/ml which produced the maximal sensitivity and specificity for the diagnosis of human brucellosis.Conclusion: Both the (IgG + IgM ELISA and Brucellacapt tests demonstrate a high specificity in this study. According to the results of the current study, it is found that both tests are valuable tools for diagnosis of brucellosis in Iran as an endemic area of brucellosis. It is strongly suggested that a combination of both tests to be used for the diagnosis of brucellosis

    Nigeria is the most populous country in Africa, has a large proportion of the world's poor livestock keepers, and is a hotspot for neglected zoonoses. A review of the 127 accessible publications on brucellosis in Nigeria reveals only scant and fragmented evidence on its spatial and temporal distribution in different epidemiological contexts. The few bacteriological studies conducted demonstrate the existence of Brucella abortus in cattle and sheep, but evidence for B. melitensis in small ruminants is dated and unclear. The bulk of the evidence consists of seroprevalence studies, but test standardization and validation are not always adequately described, and misinterpretations exist with regard to sensitivity and/or specificity and ability to identify the infecting Brucella species. Despite this, early studies suggest that although brucellosis was endemic in extensive nomadic systems, seroprevalence was low, and brucellosis was not perceived as a real burden; recent studies, however, may reflect a changing trend. Concerning human brucellosis, no studies have identified the Brucella species and most reports provide only serological evidence of contact with Brucella in the classical risk groups; some suggest brucellosis misdiagnoses as malaria or other febrile conditions. The investigation of a severe outbreak that occurred in the late 1970s describes the emergence of animal and human disease caused by the settling of previously nomadic populations during the Sahelian drought. There appears to be an increasing risk of re-emergence of brucellosis in sub-Saharan Africa, as a result of the co-existence of pastoralist movements and the increase of intensive management resulting from growing urbanization and food demand. Highly contagious zoonoses like brucellosis pose a threat with far-reaching social and political consequences. PMID:25058178

    Chronic infections may have negative impacts on wildlife populations, yet their effects are difficult to detect in the absence of long-term population monitoring. Brucella abortus, the bacteria responsible for bovine brucellosis, causes chronic infections and abortions in wild and domestic ungulates, but its impact on population dynamics is not well understood. We report infection patterns and fitness correlates of bovine brucellosis in African buffalo based on (1) 7 years of cross-sectional disease surveys and (2) a 4-year longitudinal study in Kruger National Park (KNP), South Africa. We then used a matrix population model to translate these observed patterns into predicted population-level effects. Annual brucellosis seroprevalence ranged from 8·7% (95% CI = 1·8-15·6) to 47·6% (95% CI = 35·1-60·1) increased with age until adulthood (>6) and varied by location within KNP. Animals were on average in worse condition after testing positive for brucellosis (F = -5·074, P pregnancy or being observed with a calf. For the range of body condition scores observed in the population, the model-predicted growth rate was λ = 1·11 (95% CI = 1·02-1·21) in herds without brucellosis and λ = 1·00 (95% CI = 0·85-1·16) when brucellosis seroprevalence was 30%. Our results suggest that brucellosis infection can potentially result in reduced population growth rates, but because these effects varied with demographic and environmental conditions, they may remain unseen without intensive, longitudinal monitoring.

    This cross-sectional study investigated the prevalence of brucellosis and bovine tuberculosis (BTB) in local cattle and goat breeds of Oromo and Afar pastoralist communities living in two distinct parts around the Awash National Park. A questionnaire survey was carried out to assess information on husbandry, milk consumption habits, and on knowledge-attitude-practice regarding both diseases. Among a total of 771 animals from all sites tested by comparative intradermal tuberculin test (CIDT) none were BTB reactors with the >4mm cut-off. Using the >2mm cut-off, individual apparent prevalence was 0.9% (95%CI: 0.23-3.56%) in cattle and 0.7% (95%CI: 0.12-3.45%) in goats. Herd prevalence in Oromia and Afar sites was 0% and 66.7% respectively in goats and 16.7% and 50% in cattle. Among the 327 animals tested by enzyme linked immunoassay for brucellosis, 4.8% (95%CI: 1.2-17.1%) of cattle and 22.8% (95%CI: 5.98-29.5%) of goats were reactors. Highest individual prevalence of both diseases was found in Afar settlements with brucellosis being as high as 50%. Respondent ethnicity was the only risk factor for brucellosis positivity in goats in the univariable risk factor analysis. Knowledge about the diseases was poor. Raw goat milk was regularly consumed by women and children, putting them at risk for brucellosis. This study highlighted an increased prevalence gradient of BTB and brucellosis from West to East along the study sites with high brucellosis individual prevalence and abortion rates among Afar settlements in particular.

    Full Text Available Abstract Background Brucellosis is a multi-system disease that may present with a broad spectrum of clinical manifestations. While hepatic involvement in brucellosis is not rare, it may rarely involve the kidney or display with cardiac manifestations. Central nervous system involvement in brucellosis sometimes can cause demyelinating syndromes. Here we present a case of brucella hepatitis, myocarditis, acute disseminated encephalomyelitis, and renal failure. Case presentation A 26-year-old man presented with fever, ataxia, and dysarthria. He was a shepherd and gave a history of low grade fever, chilly sensation, cold sweating, loss of appetite, arthralgia and 10 Kg weight loss during the previous 3 months. He had a body temperature of 39°C at the time of admission. On laboratory tests he had elevated level of liver enzymes, blood urea nitrogen, Creatinine, Creatine phosphokinase (MB, and moderate proteinuria. He also had abnormal echocardiography and brain MRI. Enzyme-linked immunosorbent assay for IgG and IgM was negative. Standard tube agglutination test (STAT and 2-mercaptoethanol (2-ME titers were 1:80 and 1:40 respectively. Finally he was diagnosed with brucellosis by positive blood culture and the polymerase chain reaction for Brucella mellitensis. Conclusion In endemic areas clinicians should consider brucellosis in any unusual presentation involving multiple organ systems, even if serology is inconclusive. In endemic areas low STAT and 2-ME titers should be considered as an indication of brucellosis and in these cases additional testing is recommended to rule out brucellosis.

    Full Text Available Aim: Brucellosis is a disease of zoonotic importance as it affects both human as well as animal’s health, and therefore, directly affects animal productivity and human efficiency. Therefore, a study was conducted to estimate the seroprevalence of brucellosis in humans in Jammu and surrounding areas. Materials and Methods: A total of 121 sera samples from humans occupied with professional related to animals were collected and tested for anti-Brucella antibodies by Rose Bengal plate test (RBPT, modified RBPT (mRBPT, standard tube agglutination test (STAT, and indirect enzyme-linked immunosorbent assay (I-ELISA. Sampling was done keeping in view with the occupation, sex, and age. Results: The overall seroprevalence of brucellosis recorded was 4.96%. The test-wise seroprevalence was 9.91% by RBPT, 9.91% by mRBPT, 9.09% by STAT, and 16.52% by I-ELISA. The prevalence of brucellosis was higher in >35-50 years age group compared to >20-35 years and >50-65 years. Sex-wise seroprevalence was higher in males than females. Taking I-ELISA as standard, the relative sensitivities of mRBPT, RBPT, and I-ELISA were in the order of mRBPT=RBPT>STAT. All the tests revealed high specificity values; however, among different serological tests, I-ELISA detected a maximum number of positive sera samples. Conclusions: The prevalence of brucellosis was found to be approximately 5%. The adult (>35-50 years age male group was most vulnerable. The routine diagnosis of brucellosis involved the conventional serological tests, viz., RBPT and STAT, but each was associated with drawbacks which could give either false-positive or false-negative interpretation. Therefore, it is always recommended to use a battery of tests in the diagnosis of brucellosis.

    Full Text Available Objective: Brucellosis is a prevalent disorder in children of developing countries. The aim of this study is to describe the epidemiology and long term prognosis of Brucellosis in Khorasan, Iran.Methods: This is a descriptive cross sectional study (from November 2003 up to February 2006, the subjects of which are composed of 82 patients (from Imam Reza hospital, Mashhad, and Health Center of Kashmar. In this study the diagnosis of Brucellosis is based on serology accompanied with clinical signs and symptoms. Our strategy for duration of treatment was to treat all patients for at least 6 weeks. We followed the patients by phone and if necessary by visiting.Findings: During 38 months we had 82 children with Brucellosis. The mean age was 8.02 y, and 40% of them were girls (M/F=1.21. Summer with 45.9% of the cases was the peak season. History of consuming raw dairy products, close contact with farm animals, living in village and Brucellosis in family was found in 91.6%, 76%, 70.24% and 41.1% of the cases respectively. The presenting symptom in 79.7% of the cases was joint pain, 72.9% had history of fever during the course of the disease. Arthritis, splenomegaly and lymphadenopathy were found in 60.97%, 16.9%, 7.5%, of patients respectively. The therapeutic regimen of 48.7% of our patients was Co-trimoxazole and rifampin. We followed 74% of the patients for at least 3 years which showed the relapse rate of 6.5 %. There was a case of reinfection, a patient with residual sequel and one death related to Brucellosis in our case series.Conclusion: Brucellosis is still a common disease in our children and at least a risk factor for it can be found in the history of almost all cases of pediatric Brucellosis. With at least six weeks treatment with two antibiotics and with close follow up, we can decrease the relapse rate in pediatric Brucellosis to zero, even without repeating the serology during or after treatment

    Aim: To determine the seroepidemiological patterns of bovine brucellosis in three senatorial zones of Bauchi State, Nigeria. Materials and Methods: Blood samples were aseptically collected from the anterior jugular vein of 336 slaughtered cattle, between September 2013 and March 2014 in three senatorial zones of Bauchi State, Nigeria. The sera obtained were screened for brucellosis using rose Bengal plate test (RBPT) and serum agglutination test (SAT) in parallel. The data generated was subjected to Chi-square and Fishers exact test analysis to establish whether there is a relationship between the breeds, sex, and location of the animals sampled. Results: Of the 336 cattle screened, 18 (5.4%) and 13 (3.9%) were positive by RBPT and SAT, respectively. There was no statistically significant association (p>0.05) between the sex, age, and location of cattle with seropositivity of brucellosis in the state. It was concluded that brucellosis is prevalent in Bauchi State. Further study is recommended in other abattoirs and herds of cattle in Bauchi State for confirmation of the status of the disease among cattle slaughtered in the state. Conclusion: A high seroprevalence of brucellosis among the cattle in Bauchi state indicates that the disease is endemic and cattle are one of the animals that perpetuate and sustain the disease.

    Full Text Available Introduction & Objective: Brucellosis is a zoonosis with worldwide distribution. Conventional methods for diagnosis of brucellosis include serologic tests and blood culture. The aim of this study was to compare the culture of clinical specimens and serologic test for the diagnosis of brucellosis. Materials & Methods: In a 15-month period, all patients with clinical suspected brucellosis were enrolled in this comparative-descriptive study. Blood specimens for all patients were obtained for culture and serologic tests including wright, coombs' wright and 2ME. A questionnaire including demographic, clinical and paraclinical characteristics was completed for each subject. Results: A total of 149 patients were enrolled in the study. The most common symptoms were fever, malaise, myalgia and sweating. Osteoarticular complications were observed in 106 (71.1 % patients, of which, the most common type was sacroiliitis in 67 patients (45%. The results of serologic tests including wright, coombs’ wright, and 2ME were positive in 88.6%, 87.5% and 88.5% of the patients. Also, culture of clinical specimens were positive in 38.3% of the patients, of which, serology was positive in 91.2% of the patients. Conclusion: Serologic tests are useful for the diagnosis of brucellosis in most cases. Culture of blood and the clinical specimens are useful for definitive diagnosis even in patients with low titers of antibodies. (Sci J Hamadan Univ Med Sci 2015; 22 (1: 37-42

    2014-12-01

    Full Text Available The paper concerns molecular study on pathogenicity markers of fourteen Y. enterocolitica O:9 isolated from pigs in which initially positive serological reactions for brucellosis were observed (n = 41, healthy pigs, which were brucellosis-negative (n = 258, and wild boars serologically negative for brucellosis (n = 209. PCR identification proved that all isolates were ail, ystA- and myfA-positive. The plasmid encoding yadA marker was detected in nine isolates that originated from pigs serologically positive or negative for brucellosis, and from one isolate of wild boar origin. Furthermore, none of the examined isolates was ystB-positive. Results of the investigations indicate that the Y. enterocolitica O:9 isolates from pigs or wild boars, regardless of whether they were serologically positive or negative for brucellosis, may also be potentially pathogenic for humans, due to the presence of chromosomal and plasmid encoded molecular markers.

  10. Development of a new live rough vaccine against bovine brucellosis

    International Nuclear Information System (INIS)

    Brucella abortus S19 is the most commonly used attenuated live vaccine to prevent bovine brucellosis. In spite of its advantages, S19 has several drawbacks: it is abortive for pregnant cattle, is virulent for humans, and re-vaccination is not advised due to the persistence of anti-lipopolysaccharide (LPS) antibodies that hamper the immunoscreening procedures. For these reasons, there is a continuous search for new bovine vaccine candidates. We have previously characterized the phenotype of the phosphoglucomutase (pgm) gene disruption in Brucella abortus S2308, as well as the possible role for the smooth LPS in virulence and intracellular multiplication. Here we evaluate the vaccine properties of an unmarked deletion mutant of pgm. Western blot analysis of purified lipopolysaccharide and whole-cell extract from Δpgm indicate that it synthesizes O-antigen but is incapable of assembling a complete LPS. In consequence Δpgm has a rough phenotype. Experimental infections of mice indicate that Δpgm is avirulent. Vaccination with Δpgm induces protection levels comparable to those induced by S19, and generates a splenocyte proliferative response and cytokines profile typical of a Th-1 response. The ability of the mutant to generate a strong cellular Th-1 response without eliciting specific O-antigen antibodies highlights the potential use of this mutant as a new live vaccine for cattle.

    The aim of this study was to evaluate the brucellosis patients inhabiting in Mus province, in Eastern Anatolia of Turkey, retrospectively. The mean age of the patients (n: 87) was 38.1 +/- 12.4 years, and 45% of them were female. The transmission route was the consumption of unpasteurized fresh cheese (in 85%), and unboiled milk (in 45%). The most common symptoms were recorded as chills (89%), fever (87%), and arthralgia (81%). Splenomegaly (71%) and hepatomegaly (63%) were the predominant physical examination signs. Diagnosis was made based on the clinical features and positive Rose-Bengal test result (93%), however, blood cultures could not be performed due to insufficient laboratory equipment. In 92% of the patients at least one complication has been detected indicating delayed admission to the hospital, while the most common complications were sacroileitis (79%) and spondylitis (44%). Streptomycin+doxycyclin, streptomycin+doxycyclin+ ciprofloxacin, and streptomycin+doxycyclin+ rifampicin combination therapies were used in 62%, 24% and 14% of the patients, respectively, for six weeks, resulting with complete cure.

  12. Validating a bovine brucellosis elisa test for application in Uruguay

    International Nuclear Information System (INIS)

    Sera from 600 cattle on Rio Negro Island, known to be free of brucellosis, and 400 sera from vaccinated cattle but known to be negative in the Rose-Bengal test were selected for validation of the FAO/IAEA test kit for detection of antibody to Brucella abortus. Two conjugates, one a polyclonal antiserum and the other a monoclonal antibody, were evaluated. When evaluated for reproducibility using the sera from uninfected cattle, the average coefficient of variation for duplicate samples was 7.1%±5.5. The serum control samples did not exceed OD limits as established for the kit, for any of the 15 plates evaluated. When evaluated by regression analysis, the control sera had an average correlation coefficient of 0.996, indicating a high degree of agreement between the observed OD values of controls on each plate vs the expected values for those controls. Specificity in the assay was >98% as calculated by the PP or regression methods. Comparison of the monoclonal and polyclonal conjugates using sera from vaccinated cattle indicated that many of the cattle must have been vaccinated as adults because of high antibody levels detected by both conjugates. Before this assay can be used on vaccinated animals, the kit will have to be evaluated using sera from animals of known age of vaccination. (author)

    Full Text Available This study was carried out in the town of Qalegange, located in southeast of Iran, home of about 3816 camels. To study brucellosis in these animals, serological examinations including rose Bengal plat test (RBPT, MRT and 2ME were performed on 3502 camel’s serum samples. Positive results were obtained in 245 (7%, 163 (4.66% and 89 (7.92% camels thus tested, respectively. Twenty three percent of the positive camels were adult 2 years old, 36% three years old, 22% four years old, 17% five years old and the remaining 3 percent were six years old. In the infected herds, abortion rates associated with the disease ranged from 10 to 39 percent. Other ailments observed associated with brucellosis were retention of the placenta, fetal death and mummification, delayed maturity and infertility. Recommendations for brucellosis control were given, in order to increase the awareness of shepherds, by suggesting regular testing, slaughtering of infected animals and vaccinations.

  14. Cytokine profile and nitric oxide levels in sera from patients with brucellosis

    Full Text Available The aims of this study were to investigate the serum levels of some cytokines [tumor necrosis factor-alpha (TNF-alpha, interleukin 1ß (IL-1ß, IL-2R, IL-6, and IL-8] and nitric oxide (NO levels in patients with untreated brucellosis and to test the correlation of these parameters with each other. The study was conducted on 67 subjects, 37 patients with brucellosis and 30 healthy individuals with no history of Brucella infection. Brucellosis was identified by a positive blood culture and/or increased Brucella antibodies in serological tests in addition to compatible clinical symptoms. Cytokine profile analysis was performed by the immulite chemiluminescent enzyme immunometric assay whose inter- and intra-assay coefficients of variance were 2.6-3.6 and 4.4-8.5%, respectively. The levels of nitrites/nitrates, which are representative of NO levels, were measured by the Griess method. Patients with brucellosis had significantly elevated serum levels of nitrites/nitrates, IL-2R, IL-6 and IL-8 (mean ± SD, 102.8 ± 23.8 µmol/l, 806.1 ± 58.5 U/ml, 21.1 ± 2.3 pg/ml, and 8.8 ± 1.6 pg/ml, respectively compared to healthy controls, whereas TNF-alpha and IL-1ß levels were unchanged. No statistically significant correlation was detected between any of the studied cytokine levels and nitrate/nitrite concentrations according to Pearson's linear correlation test. We conclude that only IL-6, IL-8 and IL-2R are elevated in brucellosis and the extent of elevation depends on the severity and clinical pattern of the disease. Moderate elevation in serum NO was comparable to that observed in previous studies. This explains the absence or very rare occurrence of septic shock in brucellosis.

    2016-03-01

    Full Text Available Brucella is an intracellular Gram-negative bacterium. Previous reports showed that gene polymorphisms of cytokines can affect resistance or susceptibility to Brucella infection. Interleukin-13, a cytokine secreted by Th2 lymphocytes, has an important role in immune responses against established infections. In this study, we investigated the association of three polymorphic sites of IL-13 with susceptibility to brucellosis in Iranian population. In this study 169 patients with brucellosis and 71 healthy controls were included. DNA was extracted and genotyped for three bi-allelic polymorphisms of IL-13 gene at positions -1512A/C, -1055C/T, and +2044G/A by polymerase chain reaction-restriction fragment length polymorphism method. None of the studied alleles and genotypes of IL-13 gene (-1512A/C, -1055C/T, and +2044G/A showed significant relationship with susceptibility to brucellosis. However, among eight haplotypes, the distribution of TCG and CAA haplotypes were significantly higher in the patients compared with those in the controls (P=0.002 and P=0.034, respectively. Although, the later did not tolerate Bonferoni correction. On the contrary, the distribution of TCA haplotype was higher in the controls compared to that in the patients (P=0.01. Furthermore, TAG/TCA haplogenotypes were significantly higher among controls compared to the brucellosis patients (P=0.025. P value resulted from TCA and TAG/TCA did not tolerate Bonferroni correction. There is no association between the inheritance of different alleles and genotypes of interleukin-13 gene and susceptibility to brucellosis. However, it seems that the inheritance of some haplotypes and haplogenotypes of IL-13 can impact the susceptibility to brucellosis.

    Full Text Available Introduction & Objective: Pupils have efficient potential to increase community awareness and promoting community health through participating in the health education programs. Child to family health education program is one of the communicative strategies that was applied in this field trial study. Because of high prevalence of Brucellosis in Hamadan province, Iran, the aim of this study was promoting families’ knowledge and preventive behaviors about Brucellosis in the rural areas by using child to family health education method.Materials & Methods: In this nonequivalent control group design study three rural schools were chosen (one as intervention and two others as control. At first knowledge and behavior of families about Brucellosis were determined using a designed questionnaire. Then the families were educated through “child to family” procedure. At this stage the students gained information. Then they were instructed to teach their parents what they had learned. After 3 months following the last session of education, the level of knowledge and behavior changes of the families about Brucellosis were determined and analyzed by paired t-test.Results: The results showed significant improvement in the knowledge of the mothers. The knowledge of the mothers about the signs of Brucellosis disease in human increased from 1.81 to 3.79 ( t:-21.64 , sig:0.000 , and also the knowledge on the signs of Brucellosis in animals increased from 1.48 to 2.82 ( t:-10.60 , sig:0.000. Conclusion: Child to family health education program is one of the effective and available methods, which would be useful and effective in most communities, and also Students potential would be effective for applying in the health promotion programs.

    Full Text Available Bovine brucellosis is endemic in Nigeria; however, limited data exist on nationwide studies and risk factors associated with the disease. Using a cross-sectional sero-epidemiological survey, we determined the prevalence of and risk factors for brucellosis in slaughtered cattle in three geographical regions of Nigeria. Serum samples from randomly selected unvaccinated cattle slaughtered over a period of 3 years (between December 2010 and September 2013 from northern, southern and south-western Nigeria were tested for antibodies to Brucella abortus using the Rose Bengal test. Data associated with risk factors of brucellosis were analysed by Stata Version 12. In all, 8105 cattle were screened. An overall seroprevalence of 3.9% (315/8105 was recorded by the Rose Bengal test, with 3.8%, 3.4% and 4.0% from the northern, southern and south-western regions, respectively. Bivariate analysis showed that cattle screened in northern Nigeria were less likely to be seropositive for antibodies to Brucella spp. than those from south-western Nigeria (odds ratio = 0.94; 95% confidence interval: 0.73–1.22. However, logistic regression analysis revealed that breed ( p = 0.04 and sex ( p £ 0.0001 of cattle were statistically significant for seropositivity to Brucella spp. The study found that brucellosis was endemic at a low prevalence among slaughtered cattle in Nigeria, with sex and breed of cattle being significant risk factors. Considering the public health implications of brucellosis, we advocate coordinated surveillance for the disease among diverse cattle populations in Nigeria, as is carried out in most developed countries.Keywords: Bovine brucellosis, RBT, Epidemiology, Public Health, Nigeria

  19. Comparison of an indirect enzyme immunoassay with conventional serological tests for the diagnosis of bovine brucellosis

    International Nuclear Information System (INIS)

    In Chile, as in several other Latin American countries, brucellosis is an enzootic disease. As there is a government voluntary control programme for brucellosis, some farms are free from this disease. Currently, however, the government has initiated an eradication programme. This programme requires more accurate diagnostic techniques. The objective of this research was to compare an indirect enzyme immunoassay (I-ELISA) with the milk ring test (MRT) for detection of antibodies in milk. A second objective was to compare the I-ELISA, the Rose Bengal test (RBT) and the complement fixation test (CFT) for the detection of serum antibody

    Full Text Available Abstract Background Brucellosis is an endemic infection in Georgia. We conducted a review of patient records with a suspected or confirmed diagnosis of brucellosis over three decades at the central referral hospital for brucellosis cases, the Institute of Parasitology and Tropical Medicine (IPTM in Tbilisi. The purpose was to describe the demographic profile and clinical characteristics as well as diagnostic and treatment strategies in patients with brucellosis. Methods Data were abstracted from randomly selected patient records at the IPTM. In total, 300 records were reviewed from three time periods: 1970-73, 1988-89, and 2004-2008. Results The age distribution of patients shifted from a median age of 40 years in the first time period to 20 years in the third time period. Azeri ethnicity was an increasing proportion of the total number of cases. The frequency of relapsed infection was 14.7% (44 cases. A total of 50 patients received vaccine therapy, and although the vaccine produced immune responses, demonstrated by an increase in agglutination titers, it was not associated with improved outcome. Conclusion The demographics of brucellosis in Georgia fit a profile of persons that tend sheep. Osteoarticular complications were commonly detected, especially in children. The changing pattern of brucellosis in Georgia suggests clinicians should be updated about different trends in brucellosis in their country.

    Full Text Available Background and objective: Brucellosis is primarily a contagious disease of domestic animals causing abortion, so it is considered one of the most serious of the current public health problems, especially in developing countries. The main purpose of this study was finding the incidence of human and animal brucellosis and detection of any correlation between human and animal brucellosis in Khoy, one of the endemic regions in Iran."nMaterials and Methods: We carried out an ecological study in Khoy district in North West of Iran. We ascertained all new cases of human and animal brucellosis in the 2001-2004 period. Data were analyzed using Pearson correlation coefficient (r and square of correlation coefficient (r2. Seasonal incidence was calculated for each species."nResults: The cumulative incidence rate of human brucellosis was detected to be 175/100,000, cattle brucellosis was 391/100,000, and sheep and goat brucellosis was 105/100,000. We detected direct and incomplete correlation between human and cattle (r=0.096, r2=0.009, p value 0.742, human and sheep (r=0.267, r2=0.071, p value=0.355, and cattle and sheep (r=0.797, r2=0.635, p value=0.001."nConclusion: The most effective routes to control the disease include pasteurization or boiling of milk for human consumption, cooking all food stuff derived from animal sources, vaccination of cattle against brucellosis, isolation and slaughtering of seropositive reactors for brucellosis and providing protective clothing for humans dealing with infected cattle.

  3. Canine brucellosis: Epizootiological characteristics, therapy and control of the disease

    2006-01-01

    Full Text Available The paper describes different aspects of canine brucellosis caused by Brucella canis. The disease is present in a large number of countries all over the world, where it inflicts severe economic damages, in particular in the commercial breeding and major dog breeding facilities. The disease was discovered in 1966 in the United States of America, but there were no data about its presence or distribution in our country until 1999. It was established, following the initial investigations, that the prevalence of the disease is extremely high, and that it amounted to 4.27% among pet dogs in the territory of Belgrade. Investigations of stray dogs in the territory of Podgorica showed that the seroprevalence (an equal titer or higher than 1/200 was 9.37%, while the prevalence among stray dogs in the territory of Belgrade was 10.87%. Data for other parts of Serbia are mostly lacking, and the seroprevalence for stray dogs in the Municipality of Pozarevac amounted to over 15%, while not a single serologically positive case was found among pet dogs. In addition to the epizootiological specificities of the disease established in our country, isolates of B. canis from the territory of Serbia also indicate digressions in the test of resistance to colors with respect to the referent strain RM6/66. All isolates (SR1-SR-7 are resistant to base fuchsine, and it is probable that this characteristic could also be an important epizootiological marker. Even though the isolation of the cause is the most reliable diagnostic method, it is not possible to achieve this in most cases. That is why one of the most important tasks is to define the most ideal tests for the serological diagnostics of the disease, and the obligation of reporting the disease makes it imperative that wider-scale investigations are conducted and that measures are taken toward reducing the number of positive cases in our country. .

    Full Text Available Purpose: To determine the serum levels of proinflammatory and some of the Th1/Th2 cytokines in brucellosis and their alterations with treatment and outcome. Methods: Twenty-eight acute and seven subacute brucellosis patients diagnosed clinically were included in the study. Twenty healthy volunteers were also included. Brucella standard tube agglutination tests and blood culture were conducted on all subjects. Cytokine levels of pre- and post-treatment period serum samples were measured by ELISA. Results: The mean serum levels of IL-6, IFN-g and TNF-a were significantly higher in brucellosis patients compared to the control group ( P < 0.05. No significant differences were found between patient and control groups in terms of IL-1β , TGF-β 1, IL-2, IL-4 and IL-8 levels. There was a positive correlation between IFN-γ, TNF-α and IL-6 levels with CRP levels. IL-6, IFN-γ and TNF-α levels measured after treatment were statistically significantly lower than pre-treatment values ( P < 0.001. No differences were found in the levels of these cytokines between acute and subacute patients′ sera. IL-6, IFN-γ and TNF-α levels were higher in acute or subacute brucellosis patients. Conclusions: Although the levels of the cytokines were decreased significantly with effective and adequate treatment these alterations did not correlate with the extent or activity of the disease.

    Full Text Available Background and Objective: The objectives of the present study were to survey brucellosis and to determine risk factors among humans in occupational contacts with dairy cattle in suburban and peri-urban regions in Khartoum State, Sudan. Materials and Methods: Serum samples (n = 362 were collected from people in association with 11 farms with history of brucellosis in Khartoum State between August 2009 and February 2010. Results: Out of the 362 serum samples 14 (3.9% were positive for brucella infection using competitive ELISA (cELISA. A significant association was observed between the seropositivity and community living in association with brucella-infected livestock notably: Illiterate males (P = 0.002, middle age group (20-40 yrs (P = 0.003, and consumers of raw milk and milk products (P = 0.004 are at risk of infection. Conclusions: A significant association was observed between the seropositivity and community living in association with brucella-infected livestock notably: Illiterate males, middle age group (20-40 years, and consumers of raw milk and milk products are at risk of infection. The study recommends routine serological screening for brucellosis among herders and workers and their livestock particularly in regions with history of brucellosis.

    U.S. Army civil affairs public health professionals are deployed worldwide in support of current contingency operations to promote and to preserve the public health of the citizens of the occupied territory or host nation. In Iraq, they face the challenge of assisting a health care system plagued by years of neglect and inefficient bureaucracy. Iraqi efforts to track and to control infectious diseases, especially zoonotic diseases, are in their infancy. Brucellosis, a worldwide zoonotic disease of ruminants, is of particular concern in Iraq because of the close proximity of animals to humans and the cultural habits that favor disease dissemination among the population. A public health education and awareness campaign was recently developed in Ninewa Province, Iraq, to educate Iraqi citizens about brucellosis and ways to prevent it. The public health campaign used a two-pronged approach to effect change, i.e., (1) development of a social marketing campaign (public health education) about brucellosis and its prevention, with billboards, flyers, and public service announcements, and (2) mobilization of key veterinary institutions to participate in educating and training the public and farmers about brucellosis. The campaign used culturally relevant messages and was targeted to address local cultural practices, to lower disease transmission. Efforts were made to state messages using local terms and references. This approach may have utility in other public health efforts in Iraq and other postconflict stabilization operations.

    Human brucellosis is an important zoonotic disease and is especially concerning in the Kingdom of Saudi Arabia (KSA), where livestock importation is significant. We analyzed reported human brucellosis disease trends in KSA over time to help policymakers understand the magnitude of the disease and guide the design of prevention and control measures. By using data from the national registry from 2004 to 2012, we calculated the cumulative numbers by age group and months. Trends of incidence rates (IRs) by gender, nationality, and region were also calculated. We found that there was a greater number of cases (19,130) in the 15-44years age group than in any other age group. The IRs significantly decreased from 22.9 in 2004 [95% confidence interval (CI)=22.3, 23.5] to 12.5 in 2012 (95% CI=12.1, 13). Males had a significantly greater IR than females. Most cases were reported during spring and summer seasons. The IR of Saudi citizens was significantly greater than that of non-Saudis, but this difference reduced over time. The IRs of Al-Qassim, Aseer, and Hail were in the highest 25th percentile. Young, male Saudi citizens living in highly endemic areas were at greatest risk of acquiring brucellosis. We recommend vaccinating susceptible animals against brucellosis and increasing the public's awareness of preventive measures. PMID:26429071

    The relationship between host density and parasite transmission is central to the effectiveness of many disease management strategies. Few studies, however, have empirically estimated this relationship particularly in large mammals. We applied hierarchical Bayesian methods to a 19-year dataset of over 6400 brucellosis tests of adult female elk (Cervus elaphus) in northwestern Wyoming. Management captures that occurred from January to March were over two times more likely to be seropositive than hunted elk that were killed in September to December, while accounting for site and year effects. Areas with supplemental feeding grounds for elk had higher seroprevalence in 1991 than other regions, but by 2009 many areas distant from the feeding grounds were of comparable seroprevalence. The increases in brucellosis seroprevalence were correlated with elk densities at the elk management unit, or hunt area, scale (mean 2070 km2; range = [95–10237]). The data, however, could not differentiate among linear and non-linear effects of host density. Therefore, control efforts that focus on reducing elk densities at a broad spatial scale were only weakly supported. Additional research on how a few, large groups within a region may be driving disease dynamics is needed for more targeted and effective management interventions. Brucellosis appears to be expanding its range into new regions and elk populations, which is likely to further complicate the United States brucellosis eradication program. This study is an example of how the dynamics of host populations can affect their ability to serve as disease reservoirs.

    We report the largest outbreak of brucellosis in Penang, Malaysia. Brucellosis is not endemic in this region. The index case was a 45-year-old goat farm owner presented with 3 weeks of fever, headache, severe lethargy, poor appetite, and excessive sweating. He claimed to have consumed unpasteurized goat's milk that he had also sold to the public. Tests were negative for tropical diseases (i.e., dengue fever, malaria, leptospirosis and scrub typhus) and blood culture showed no growth. Based on epidemiological clues, Brucella serology was ordered and returned positive. Over a period of 1 year, 79 patients who had consumed milk bought from the same farm were diagnosed with brucellosis. Two of these patients were workers on the farm. Four laboratory staff had also contracted the disease presumably through handling of the blood samples. The mean duration from onset of symptoms to diagnosis was 53 days with a maximum duration of 210 days. A combination treatment of rifampin and doxycycline for 6 weeks was the first line of treatment in 90.5% of patients. One-third of the patients had sequelae after recovering and 21% had a relapse. We highlight the importance of Brucellosis as a differential diagnosis when a patient has unexplained chronic fever. PMID:26055742

    Brucellosis is the most frequent zoonosis reported in Qatar, mainly related to exposure to infected camels. An outbreak of human brucellosis in 14 members of a family living in a rural area in Qatar is reported herein. Clinical, epidemiological and laboratory results from all 14 patients with Brucella and 12 non-confirmed family members were collected from files. All patients reported fever for a maximum of 14 days, associated with arthralgia (6 patients), weakness (4 patients), headache (4 patients), diarrhea (2 patients) and abdominal pain (2 patients). The median age of the patients was 10 years and that of non-cases was 16 years, with a predominance of males (92.9%). Elevated levels of transaminases were observed in patients. A mixed infection caused by Brucella abortus and Brucella melitensis was identified by blood culture and serology. The source of the infection was the milk of an infected camel. The outbreak of brucellosis melitensis/abortus related to the consumption of camel milk constitutes a gap in the prevention and control of the potential sources of brucellosis in animal farms. Proper control and education of the population are required. PMID:26796768

    Although the development of the 2009 SpA classification criteria by Assessment of SpondyloArthritis international Society (ASAS) represents an important step towards a better definition of the early disease stage particularly in axial spondyloarthritis (axSpA), the specificity of the criteria has been criticized these days. As the commonest zoonotic infection worldwide, human brucellosis can mimic a large number of diseases, including SpA. This study was performed to determine the frequency of rheumatologic manifestations in patients with brucellosis and the chance of misdiagnosing them as having axSpA in central China. The results showed that clinical manifestations of axSpA could be observed in brucellosis. Over half of patients had back pain, and one fifth of the patients with back pain were less than 45 years old at onset and had the symptom for more than 3 months. Two young males were falsely classified as suffering from axSpA according to the ASAS criteria, and one with MRI proved sacroiliitis was once given Etanercept for treatment. Therefore, differential diagnosis including human brucellosis should always be kept in mind when applying the ASAS criteria, even in traditionally non-endemic areas. PMID:27376805

    Every winter, government agencies feed ???6000 metric tons (6 ?? 106 kg) of hay to elk in the southern Greater Yellowstone Ecosystem (GYE) to limit transmission of Brucella abortus, the causative agent of brucellosis, from elk to cattle. Supplemental feeding, however, is likely to increase the transmission of brucellosis in elk, and may be affected by climatic factors, such as snowpack. We assessed these possibilities using snowpack and feeding data from 1952 to 2006 and disease testing data from 1993 to 2006. Brucellosis seroprevalence was strongly correlated with the timing of the feeding season. Longer feeding seasons were associated with higher seroprevalence, but elk population size and density had only minor effects. In other words, the duration of host aggregation and whether it coincided with peak transmission periods was more important than just the host population size. Accurate modeling of disease transmission depends upon incorporating information on how host contact rates fluctuate over time relative to peak transmission periods. We also found that supplemental feeding seasons lasted longer during years with deeper snowpack. Therefore, milder winters and/or management strategies that reduce the length of the feeding season may reduce the seroprevalence of brucellosis in the elk populations of the southern GYE. ?? 2007 by the Ecological Society of America.

    The incidence of human brucellosis is not documented in Rwanda despite several reports on the disease in cattle. Because brucellosis has been associated with abortion, the aim of this study was to investigate the prevalence of positive serology in women presenting with abortion and/or stillbirth. The study was done in Huye District, in the Southern Province of Rwanda, and the patients were recruited from both the University Teaching Hospital of Butare (CHUB) and Kabutare District Hospital. Serum samples were collected and the Rose Bengal plate test (RBPT) was performed on each sample. A questionnaire was also used to investigate potential contacts with animals and/or consumption of raw milk. A total of 60 women were recruited and 15 (i.e., 25%) were Brucella seropositive. The questionnaire showed that those with seropositivity either were in contact with domestic animals (cattle, goat, or sheep) or were consuming raw cow's milk. Human brucellosis appears to be of public health importance in Rwanda and more attention should be drawn on the disease. The current study provides a basis for larger studies to establish the incidence of human brucellosis in Rwanda. More mechanistic studies will also demonstrate the pathogenicity of Brucella in human placentas. PMID:25101131

    Full Text Available Objectives: The clinical utility of complementary tests for brucellosis are not clear in many situation. This study aimed toevaluate value of these tests for brucellosis in an endemic area in Turkey.Materials and methods: This study was performed at Çanakkale General Hospital in 2009. In a retrospective approach, recordsof the patients who evaluated for brucellosis were collected. During the study period, 236 people (131 symptomaticand 105 non-symptomatic were evaluated for diagnosis of brucellosis. All of the samples from these patients were testedfor Brucella antibody seropositivity by RB slide agglutination, standard serum agglutination, Brucella Coombs, BrucellaCapt,and ELISA IgG and IgM tests. Results: In total, 49 symptomatic patients were hospitalized and blood cultures wereobtained. Brucella spp. were isolated from nine of them (18.4%.The BrucellaCapt test was found to be the most sensitivefor Brucella (74.0% and close behind it was the Coombs test (72.5%. The sensitivity for the RB test was 48.1%. The ELISAIgG test was found more sensitive for brucellosis than the ELISA IgM test was (65.6% and 49.6%, respectively. All examinedtests were found about 100% specific for brucellosis but the RB test was found less specific than the others were (96.1%Positive predictive value for all tests was about 1 but negative predictive values were only valuable for the Coombs andBrucella Capt test (0.744 and 0.755, respectively.

    Full Text Available Background: Brucellosis is a widespread zoonotic infection. This disease is endemic in many parts of Asia, including India. Brucellosis is a major cause of pyrexia of unknown origin (PUO. Persons exposed to infected animals or contaminated animal products are at high risk. Seropositivity among animal handlers, veterinarians and dairy workers has been documented in India. Thus, the present study was aimed to determine prevalence of brucellosis among PUO cases and occupationally exposed individuals. Methods: In this study, serum samples (n=282 from cases of pyrexia of unknown origin (PUO (n=243, and occupationally exposed individuals (n=39 were collected and tested for brucellosis by Rose Bengal plate test (RBPT, serum agglutination test (SAT, indirect ELISA, IgG and IgM ELISA. Blood culture for isolation of Brucella was performed for 10 serologically positive patients using BACTEC 9050 automated blood culture system. Biochemical tests and PCR techniques were used for confirmation of the isolates. Results: Of the samples tested, 4.25%, 3.54%, 6.02% and 4.96% samples were positive by RBPT, SAT, indirect ELISA and IgG ELISA, respectively. None of the sample was positive for IgM ELISA. Of the 10 blood samples cultured bacteriologically, one Brucella isolate was recovered. The isolate was confirmed as Brucella abortus. Amplification of the bcsp31 and IS711 genes was also observed. Conclusions: Seropositivity for brucellosis was observed among PUO cases, animal handlers and dairy workers in Goa, India. The serological tests showed variable results. One Brucella isolate was obtained by performing blood culture. Confirmation of the case was done rapidly using molecular tools. General awareness about clinical symptoms should be increased which will improve proper diagnosis within short time frame.

    Bovine brucellosis is endemic in Nigeria; however, limited data exist on nationwide studies and risk factors associated with the disease. Using a cross-sectional sero-epidemiological survey, we determined the prevalence of and risk factors for brucellosis in slaughtered cattle in three geographical regions of Nigeria. Serum samples from randomly selected unvaccinated cattle slaughtered over a period of 3 years (between December 2010 and September 2013) from northern, southern and south-western Nigeria were tested for antibodies to Brucella abortus using the Rose Bengal test. Data associated with risk factors of brucellosis were analysed by Stata Version 12. In all, 8105 cattle were screened. An overall seroprevalence of 3.9% (315/8105) was recorded by the Rose Bengal test, with 3.8%, 3.4% and 4.0% from the northern, southern and south-western regions, respectively. Bivariate analysis showed that cattle screened in northern Nigeria were less likely to be seropositive for antibodies to Brucella spp. than those from south-western Nigeria (odds ratio = 0.94; 95% confidence interval: 0.73-1.22). However, logistic regression analysis revealed that breed ( p = 0.04) and sex ( p £ 0.0001) of cattle were statistically significant for seropositivity to Brucella spp. The study found that brucellosis was endemic at a low prevalence among slaughtered cattle in Nigeria, with sex and breed of cattle being significant risk factors. Considering the public health implications of brucellosis, we advocate coordinated surveillance for the disease among diverse cattle populations in Nigeria, as is carried out in most developed countries.

    Bovine brucellosis was first reported in Peninsular Malaysia in 1950. A subsequent survey conducted in the country revealed that the disease was widespread. Current knowledge on the potential risk factors for brucellosis occurrence on cattle farms in Malaysia is lacking. Therefore, we conducted a case-control study to identify the potential herd-level risk factors for bovine brucellosis occurrence in four states in the country, namely Kelantan, Pahang, Selangor and Negeri Sembilan. Thirty-five cases and 36 controls of herds were selected where data on farm management, biosecurity, medical history and public health were collected. Multivariable logistic regression identified that Brucella seropositive herds were more likely to; have some interaction with wildlife (OR 8.9, 95% CI = 1.59-50.05); originated from farms where multiple species such as buffalo/others (OR 41.8, 95% CI = 3.94-443.19) and goat/sheep (OR 8.9, 95%Cl = 1.10-71.83) were reared, practice extensive production system (OR 13.6, 95% CI 1.31-140.24) and have had episodes of abortion in the past (OR 51.8, 95% CI = 4.54-590.90) when compared to seronegative herds. Considering the lack of information on the epidemiology of bovine brucellosis in peninsular Malaysia and absence of information on preventing the inception or spread of the disease, this report could contribute to the on-going area-wise national brucellosis eradication program.

    Full Text Available Brucellosis is one of the most common diseases among human that identification and control of disease transmission methods can promote public health. Clinical signs alone are not sufficient for brucellosis diagnosis. Hence, a sensitive, specific, rapid and inexpensive method is required. Early and appropriate diagnosis of this disease is effective in improving public health as well as disease control and eradication. Several serological tests for probable diagnosis of Brucella infection were used in evaluation of antibodies against Brucella. Using new methods such as Elisa has higher sensitivity and specificity than standard SAT test and complement fixation which can show both G and M immunoglobulins. It is also suitable for examining certain class of immunoglobulin. Research and studies have shown that ELISA is a complete method for in vitro detection of chronic disease, especially when other tests results are negative. In addition to this method, all unique and specific immunoglobulin in tested serum appear with high speed and accuracy. Another diagnostic method is PCR, which has higher sensitivity and specificity in comparison with serologic methods for diagnosis of human brucellosis. PCR shows similar sensitivity as 16srRNA using L7/L12 gene. It can be used in diagnosis of human brucellosis. Another diagnostic method is identification of different forms of IL-10 gene, which is a cytokine. It inactivates macrophages and infects the susceptible subject with brucellosis. Therefore, identification of different forms of IL-10 gene is considered as effective method for diagnosis of the disease. It’s recommended to use this new and effective method because many of these methods can overcome limitations of traditional methods.

  9. Prediction and control of brucellosis transmission of dairy cattle in Zhejiang Province, China.

    Juan Zhang

    Full Text Available Brucellosis is a bacterial disease caused by brucella; mainly spread by direct contact transmission through the brucella carriers, or indirect contact transmission by the environment containing large quantities of bacteria discharged by the infected individuals. At the beginning of 21st century, the epidemic among dairy cows in Zhejiang province, began to come back and has become a localized prevalent epidemic. Combining the pathology of brucellosis, the reported positive data characteristics, and the feeding method in Zhejiang province, this paper establishes an SEIV dynamic model to excavate the internal transmission dynamics, fit the real disease situation, predict brucellosis tendency and assess control measures in dairy cows. By careful analysis, we give some quantitative results as follows. (1 The external input of dairy cows from northern areas may lead to high fluctuation of the number of the infectious cows in Zhejiang province that can reach several hundreds. In this case, the disease cannot be controlled and the infection situation cannot easily be predicted. Thus, this paper encourages cows farms to insist on self-supplying production of the dairy cows. (2 The effect of transmission rate of brucella in environment to dairy cattle on brucellosis spreading is greater than transmission rate of the infectious dairy cattle to susceptible cattle. The prevalence of the epidemic is mainly aroused by environment transmission. (3 Under certain circumstances, the epidemic will become a periodic phenomenon. (4 For Zhejiang province, besides measures that have already been adopted, sterilization times of the infected regions is suggested as twice a week, and should be combined with management of the birth rate of dairy cows to control brucellosis spread.

    Objective: To determine brucellosis's epidemiologic, laboratory, diagnostic and public health features considering brucellosis is endemic in Azna County, western Iran. Methods: This descriptive cross-sectional study was investigated on 43 patients with brucellosis in Azna County. The subjects were the patients with symptoms correspondent with brucellosis and positive Wright and 2ME tests. A questionnaire about demographic, epidemiological and laboratory findings was filled in. Afterwards, patients were treated using usual antimicrobial drugs regimen. The collected data were analyzed by SPSS software version 16. Results:Forty-three subjects were found to be positive in laboratory tests. Incidence of Brucellosis was 59.31 per hundred thousand population. About 34.9% of patients were female and 65.1% male. Nearly 95.2 % of human cases were living in rural and 4.8 % in urban areas. Around 20.9% of patients had history of animal contact. The commonest transmission was unpasteurized dairy products (79.1%). The most contagious seasons were summer and spring (60.3%). The most common age group was 15-24 (27.9%), and about 60.5% of the patients were between 15-44 years old. Disease was more common among housewives (30.2%) and farmers (20.9%). The majority of the patients had Wright test titre=1:320 (54.1%) and 2ME test titre=1:160 (56.1%) in serological titration. Doxycycline with Rifampin was used for treatment of the greatest of patients (60.4%). Conclusions:In order to control this zoonotic disease, close cooperation of health and veterinary organizations is necessary.

    Brucellosis is one of the most widespread zoonoses in the world caused by several species of the genus Brucella. The disease, eradicated in many developed countries, is a re-emerging neglected zoonosis endemic in several zones especially in the Mediterranean region, impacting on human health and livestock production. A One Health approach could address brucellosis control in Morocco but scarcity of reliable epidemiological data, as well as underreporting, hinders the implementation of sustainable control strategies. Surveillance and control policies implemented by the Moroccan government in domestic animals (cattle and small ruminants) in the last few decades are assessed for disease impact. This study considers the origins of animal brucellosis in Morocco and the potential for emergence of brucellosis during a shift from extensive to intensive livestock production. PMID:26690090

    Brucellosis, a zoonotic disease which is especially seen in developing countries is still an important public health problem worldwide. Crimean-Congo hemorrhagic fever (CCHF) is another zoonotic disease that transmits to humans by infected tick bites as well as exposure to blood or tissue from infected animals. Both of the diseases are common among persons who live in rural areas and deal with animal husbandry. Since brucellosis usually presents with non-specific clinical symptoms and may easily be confused with many other diseases, the diagnosis of those infections could be delayed or misdiagnosed. In this report, a case of coinfection of brucellosis and CCHF has been presented to emphasize the possibility of association of these infections. A 70-year-old female patient with a history of dealing with animal husbandry in a rural area admitted to our hospital with the complaints of fever, malaise, generalized body and joint pains, and headache. Her complaints had progressed within the past two days. She also reported nausea, vomiting, abdominal pain and bloody diarrhea. She denied any history of tick bites. Her physical examination was significant for the presence of 38.8°C fever, increased bowel sounds and splenomegaly. Laboratory analysis revealed leukopenia, thrombocytopenia and high levels of liver enzymes. The patient was admitted to our service with the prediagnosis of CCHF. Serum sample was sent to the Department of Microbiology Reference Laboratory at Public Health Agency of Turkey for CCHF testing. During patient's hospitalization in service, more detailed history was confronted and it was learned that she had fatigue, loss of appetite, sweating, joint pain, and intermittent fever complaints were continuing within a month and received various antibiotic treatments. The tests for brucellosis were conducted and positive results for Brucella Rose Bengal test, tube agglutination (1/160 titers) and immune capture test with Coombs (1/320 titers) were determined

    The prevalence of mastitis and brucellosis in urban and peri-urban settings was studied in Awassa and two smaller nearby towns in southern Ethiopia, because milk-born diseases are causing a risk for human health, besides direct impacts on animal production. Mastitis was investigated by examining 80 cows (320 udder quarters) using California mastitis test (CMT) and somatic cell count (SCC). The prevalence of brucellosis was assessed by sampling 177 cattle in Awassa and its peri-urban areas using serological methods. Logistic regression was used to analyse risk factors associated with mastitis. Prevalence of clinical mastitis on quarter level was 0.9%, and 1.9% of quarters were non-functional or blocked. Prevalence of sub-clinical mastitis at quarter level in urban and peri-urban areas was significantly different (P CMT (42.5%) was close to the percentage-positive detected by SCC (41.2%). Prevalence of brucellosis was 3.9% in the peri-urban area, while no brucellosis cases were detected in Awassa. More frequent use of artificial insemination in the urban than in peri-urban area might have contributed to the absence of brucellosis in the urban location. The extent of mastitis is, however, a threat to the dairy enterprise in and around Awassa. Pasteurization of milk and milk products is indicated in some parts of the area because of the danger of brucellosis. PMID:19309482

    There are few publications on brucellosis within the Pacific Island Countries and Territories (PICTs). The reason is possibly because the cattle population has been reportedly free of the disease for many years until a re-emergence occurred in the Fiji Islands (Viti Levu) in 2009. This paper reports on the outbreak of brucellosis in Fiji and its progression between 2009 and 2013 in the context of an overview of brucellosis in the Pacific Island community. Review of the literature found only 28 articles with the oldest record of brucellosis being in 1965 in Papua New Guinea (PNG) and from human cases in Tonga in 1980. The Fiji outbreak of Brucella abortus occurred in cattle in 2009 (Wainivesi basin) in the Tailevu province. Prior to the outbreak, Fiji declared freedom from B. abortus to OIE in 1996 after a successful eradication campaign. During the course of the outbreak investigation, serum samples were collected from between 9790 and 21,624 cattle per annum between 2009 and 2013 from 87 farms on the main island of Fiji (Viti Levu). Blood samples were tested for brucellosis using the Rose Bengal Test (RBT) in 2009 and the indirect ELISA test in subsequent years. At the time of the outbreak in Fiji (2009) the apparent prevalence in cattle was 1.50% and this has fluctuated since the outbreak. The True Prevalence (TP) for the main island in Fiji for the indirect ELISA tests was 2.40% in 2010, reached a peak of 3.49% in 2011 then reduced to 0.12% by 2013. The significant reduction in prevalence compared to 2010 is most likely due to the control programs being implemented in Fiji. The re-emergence of B. abortus in Fiji could be attributed to the lack of monitoring for the disease until 2009 combined with inadequate management of exposed animals, thus illustrating how important it is for authorities not to become complacent. Continued awareness and monitoring for brucellosis is essential if future outbreaks are to be avoided. PMID:26497272

    Brucellosis, especially caused by Brucella melitensis, remains one of the most common zoonotic diseases worldwide with more than 500000 human cases reported annually. The bacterial pathogen is classified by the CDC as a category (B)pathogen that has potential for development as a bio-weapon. Brucella spp. is considered as the most common laboratory-acquired pathogens. The geographical distribution of brucellosis is constantly changing with new foci emerging or re-emerging.The disease occurs worldwide in both animals and humans, except in those countries where bovine brucellosis has been eradicated. The worldwide economic losses due to brucellosis are extensive not only in animal production but also in human health. Although a number of successful vaccines are being used for immunization of animals, no satisfactory vaccine against human brucellosis is available. When the incidence of brucellosis is controlled in the animal reservoirs, there is a corresponding and significant decline in the incidence in humans.%布病,尤其是由羊种布鲁氏菌引起的布病,目前是世界上最常见的一种人兽共患传染病,全世界每年报道的布病病例超过500万.布鲁氏菌已经被CDC列为B类病原体,成为潜在的生物武器.布鲁氏菌也是最常见的实验室源性病原体.布病的流行地域在不断变化,每年都有新发地和复发地的报道.除了那些牛布病已经根除的国家,布病仍然在许多国家的人和动物中存在.全世界由于布病给动物产品及公共卫生安全而带来的经济损失是巨大的.虽然许多有效的疫苗正在用于动物免疫,但是还没有理想的人用疫苗可以使用.动物布病的控制将显著降低人布病的发生.

    Full Text Available A study of the prevalence of camel brucellosis has been carried out in the south province of Jordan during the years 2006 and 2007. Six hundred forty camel sera from 44 herds were randomly collected and analyzed. Rose Bengal plate test was used to screen all serum samples. The positive samples were subjected to confirmation by complement fixation test. The true prevalence of Brucella seropositive was 15.8%. Brucella melitensis biotype 3 was isolated from 2 aborted fetuses and from 2 milk samples. 64.8% of the positive camels were adult > than 4 years old and the remaining 35.2% were young ranging from 6 months to 4 years old. Recommendations for brucellosis control were given.

    Full Text Available Coincidence of isolated testicular abscess and epidural-paravertebral abscess is a rare complication of brucellosis. A 24-year-old male patient was admitted to our clinic with 2 months ongoing back pain, night sweats and left scrotal pain. Septal cystic lesion with dense content in the left testis was considered to isolated testicular abscess in scrotal Doppler examination. Multiple spinal epidural and right paraspinal abscess were detected in the spinal magnetic resonance imaging. The patient was treated with drainage of abscess and oral antibiotics. The rare combination of spinal epidural and testicular abscess should be kept in the mind if a patient presented with low back pain and scrotal pain in regions where brucellosis was endemic.

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the performance of a competitive ELISA system for the diagnosis of bovine brucellosis in comparison to conventional aerological tests routinely used in Argentina. A total of 2.500 serum samples, comprising Brucella-free herds, vaccinated cattle and naturally infected animals, was tested by the following tests: buffered plate agglutination, Rose Bengal, 2-mercaptoethanol, complement fixation, and indirect and competitive ELISAs. Specificity and relative sensitivity at each test were determined. The competitive ELISA was considered suitable for detection of vaccinated animals and had higher specificity than the other tests. The results point to the potential use of the test as a complementary assay in the brucellosis control programme in Argentina. (author)

    Summary Kyrgyzstan reported 77.5 new cases of human brucellosis per 100,000 inhabitants in 2007, which is one of the highest incidences in the world. However, because this number is based on official records, it is very likely that the incidence is underreported. The diagnostic tests most commonly used in Kyrgyzstan are the Rose Bengal test in ruminants and the Huddleson test in humans. The sensitivity and specificity of these tests have never been evaluated under field conditions in Kyrgyzstan, where the strains circulating in livestock and humans are unknown. Therefore, a representative national cross-sectional serological study was undertaken in humans, cattle, sheep and goats to assess the true seroprevalence and to compare different serological tests. In the year of study (2006), few animals were vaccinated against brucellosis in Kyrgyzstan. A total of 5,229 livestock sera and 1,777 human sera from three administrative regions were collected during spring 2006 and submitted to a range of serological tests. The true seroprevalence of brucellosis, estimated using Bayesian methodology, was 7% (95% credibility interval 4%–9%) in humans, 3% (1%–5%) in cattle, 12% (7%–23%) in sheep and 15% (7%–30%) in goats. The Rose Bengal test was confirmed as a useful screening test in livestock and humans, although its sensitivity was lower than that of other tests. The estimates of specificity of all tests were significantly higher than those for sensitivity. The high seroprevalence of brucellosis in humans, cattle and small ruminants in Kyrgyzstan was confirmed. Bayesian statistical approaches were demonstrated to be useful for simultaneously deriving test characteristics and true prevalence estimates in the absence of a gold standard. PMID:24761732

A few reports and the authors’ experiences indicate that tuberculosis may result in a false-positive brucellosis serology. This may cause a diagnostic challenge because of the close clinical resemblance of these two infections.Objective: The aim of the present prevalence study was to elucidate brucellosis seroreactivity in patients with active TB.Methods: Ninety-eight patients with newly diagnosed and active TB were studied using an enzyme-linked immunosorbent assay (ELISA and Wright’s and Coombs–Wright’s tests. Seventy-five healthy individuals were used as controls. The patients showed signs of recovery after starting a standard anti-TB regimen and had no clinical evidence of brucellosis at a subsequent 6-month follow-up. The data were analyzed statistically by Fisher’s exact test using SPSS 11.0.Results: We found that 9.2% of TB patients versus 1.3% of healthy controls had positive results on the anti-Brucella IgG ELISA (P = 0.04. Five TB patients were found to have agglutination on Wright’s tests, while none of the controls showed agglutination.Conclusion: Active TB patients may have some seroreactivity with Brucella antigens, and Brucella IgG ELISA may give a false positive in these patients. Clinicians should consider false positive brucellosis seroreactivity in patients with active TB.Keywords: false positive serology, ELISA, diagnosis

    2014-06-01

    Full Text Available Background and Objective: In our country, the Wright test routinely is used for diagnosing brucellosis. Because of its low sensitivity, the range of false-negative results is high. Therefore, we aimed at comparing Wright and ELISA in the people suspected brucellosis. Material and Methods: The results of Wright, 2ME, Coombs Wright tests were compared with Anti-Brucella IgG, Anti-Brucella IgM. Of 1183 subjects referred for Wright test, 148 of them were investigated for Coombs Wright and 228 for 2ME Wright. In addition to Wright test for 32 cases, Brucella IgG and IgM classes were also experimented. Results: Wright test was negative in 95.4% of cases. Of these negative results, 2.3% were positive for Coombs Wright. Eight-point-five percent of the cases were positive for Coombs Wright test and 4.7% for 2ME Wright test. Sixteen cases were negative for both Wright and ELISA. In 8 cases of Wright-negative, ELISA IgM class was positive and IgG class was negative, and in 4 cases of Wright-negative, ELISA IgM was negative and IgG was positive. About 4 cases of Wright-positive, IgM and IgG antibody classes were positive. Conclusion: Due to the mismatch between the results of Wright agglutination test and ELISA method and with regard to availability, high sensitivity and determining the type of antibody classes in ELISA, it is focused on ELISA method for brucellosis diagnosis.

    Bacteria of the genus Brucella cause brucellosis, the most common bacterial zoonosis worldwide. The diagnosis of Brucella abortus and Brucella melitensis ruminant brucellosis is based on bacteriological and immunological tests, the latter being routinely used in control and eradication and surveillance programs. Infections by smooth and rough Brucella spp., the use of smooth and rough vaccines, and the false-positive serological reactions caused by Yersinia enterocolitica O:9 and other cross-reacting bacteria represent the immunological contexts in which those tests are used. This complex context explains the large number of brucellosis tests that have been developed, and that vary in antigen type, antigen presentation, antibody and conditions for the reaction, the response detected and the sample required. This wealth of information and an imperfect understanding of Brucella antigens and of the peculiarities of the immunoresponse to Brucella has created confusion and led to several misconceptions on the usefulness and limitations of the brucellosis diagnostic tests. In this review, Brucella antigens are examined focusing on cellular topology, supramolecular properties, epitopic structure and lipopolysaccharide and protein cross-reactivity in the various contexts of the immune response in ruminants. Then, the significance of these features in diagnostic tests that use whole bacteria is discussed with respect to the activities of ruminant immunoglobulins, and the effect of pH on unspecific agglutinations, non-agglutinating and blocking antibodies, pseudo-prozones and complement activation. Similarly, the bacterial surface lipopolysaccharides and cognate polysaccharides are discussed with regards to topological effects, epitope exposure, ionic strength and antibody avidity in immunoprecipitation, immunosorbent and fluorescence polarization assays. Finally, the search for immunodominant protein antigens and their use in immunological tests is reviewed. Critical review

  9. The Value of Serologic Tests for Diagnosis and Follow up of Patients having Brucellosis

    Full Text Available Though diagnosis of human brucellosis is accurate when the causal agent is isolated, this procedure is not always successful and the most of patients are diagnosed on the basis of rising titres of antibodies in serum. The classical tests used for detection of antibodies to S-Brucella sp., include Rose Bengal (RBT, buffered plate antigen (BPAT, serum agglutination (SAT, 2-mercapto-ethanol (2MET and complement fixation (CFT. The modern methods are based on primary binding assays of which a competitive enzyme immunoassay (CELISA and fluorescence polarization (FPA are the best developed. For antibodies to R-Brucella sp. a rapid slide agglutination (RSAT as screening and an indirect ELISA (IELISA as confirmatory tests have been reported. We have selected 23 cases of human brucellosis that were followed up over a long period, to assess which test was most effective in detecting different stages of the disease. The patients were divided into five groups: “chronic” cases; relapses; infection acquired in a laboratory; patients presumptively infected with B. canis and cases with a long history of brucellosis. The results suggest that BPAT is a practical test that reduces non specific reactions and is more sensitive than RBT. SAT detects the acute form but cross reacts with other antibodies and the diagnostic end-point titre has not been satisfactorily established; 2MET should be discontinued because of its toxicity and the scant information it can add; CFT fails to detect the acute form and is technically complicated. CELISA correlate well with the clinical course and is useful to detect acute as well as “chronic” cases and FPA do not work in serum with high lipid content. RSAT and IELISA are useful tests for brucellosis caused by B. canis. A unique protocol for serologic diagnosis that uses robust tests would be of value to the surveillance and control the disease.

    2014-02-01

    Full Text Available Brucellosis screening was conducted between 2005 and 2010 at the National Livestock Research Institute headquarters, Mpwapwa, Tanzania, following an abortion storm in cattle. The initial screening targeted breeding herds; 483 cattle were screened using the Rose Bengal Plate Test (RBPT followed by the Competitive Enzyme-linked Immunosorbent Assay (c-ELISA as a confirmatory test. The seropositivity on c-ELISA was 28.95% in 2005; it subsequently declined to 6.72%, 1.17%, 0.16% and 0.00% in 2006, 2007, 2009 and 2010, respectively. Brucella seropositivity was not detected in goats. Seropositivity declined following institution of stringent control measures that included: gradual culling of seropositive animals through slaughter; isolation and confinement of pregnant cows close to calving; proper disposal of placentas and aborted foetuses; the use of the S19 vaccine; and restricted introduction of new animals. It was thought that the source of this outbreak was likely to have been from the introduction of infected animals from another farm. Furthermore, humans were found with brucellosis antibodies. Out of 120 people screened, 12 (10% were confirmed seropositive to brucella antigen exposure by c-ELISA analysis. The majority of the seropositive individuals (80% were milkers and animal handlers from the farm. Nine individuals had clinical signs suggestive of brucellosis. All cases received medical attention from the district hospital. This achievement in livestock and human health showed that it is possible to control brucellosis in dairy farms, compared to pastoral and agro-pastoral farms, thus providing evidence to adopt these strategies in dairy farms thought to be at risk.

    We studied the possible interaction between rifampin and doxycycline in 20 patients with brucellosis treated randomly with either doxycycline and streptomycin or doxycycline and rifampin. The doxycycline levels in the plasma of patients in the group treated with rifampin were significantly lower than those in the plasma of patients treated with doxycycline and streptomycin. Furthermore, clearance in patients treated with rifampin was significantly higher than that in patients treated with dox...

    Interpretation & conclusions: The present study showed an overall isolation rate of 17.64 per cent for B. melitensis. There is a need to establish facilities for isolation and characterization of Brucella species for effective clinical management of the disease among patients as well as surveillance and control of infection in domestic animals. Further studies are needed from different geographical areas of the country with different level of endemicity to plan and execute control strategies against human brucellosis.

    Full Text Available Abstract Background The optimal treatment regimen and duration of the therapy is still controversial in spinal brucellosis. The aim of this study is to compare the efficacy, adverse drug reactions, complications and cost of ciprofloxacin plus rifampicin versus doxycycline plus streptomycin in the treatment of spinal brucellosis. Methods The patients diagnosed as spinal brucellosis between January 2002 to December 2004 were enrolled into the study. Patients were enrolled into the two antimicrobial therapy groups (doxycycline plus streptomycin vs. ciprofloxacin plus rifampicin consecutively. For the cost analysis of the two regimens, only the cost of antibiotic therapy was analysed for each patient. Results During the study period, 31 patients with spinal brucellosis were enrolled into the two antimicrobial therapy groups. Fifteen patients were included in doxycycline plus streptomycin group and 16 patients were included in ciprofloxacin plus rifampicin group. Forty-two levels of spinal column were involved in 31 patients. The most common affected site was lumbar spine (n = 32, 76% and involvement level was not different in two groups. Despite the disadvantages (older age, more prevalent operation and abscess formation before the therapy of the patients in the ciprofloxacin plus rifampicin group, the duration of the therapy (median 12 weeks in both groups and clinical response were not different from the doxycycline plus streptomycin. The cost of ciprofloxacin plus rifampicin therapy was 1.2 fold higher than the cost of doxycycline plus streptomycin therapy. Conclusion Classical regimen (doxycycline plus streptomycin, with the appropriate duration (at least 12 weeks, is still the first line antibiotics and alternative therapies should be considered when adverse drug reactions were observed.

    International audience - Brucellosis control and eradication requires serological tests and vaccines. Effective classical vaccines (S19 in cattle and Rev 1 in small ruminants), however, induce antibodies to the O-polysaccharide of the lipopolysaccharide which may be difficult to distinguish from those resulting from infection and may thus complicate diagnosis. Rough attenuated mutants lack the O-polysaccharide and would solve this problem if eliciting protective immunity; the empirically o...

    Following the recent discovery of new Brucella strains from different animal species and from the environment, ten Brucella species are nowadays included in the genus Brucella. Although the intracellular trafficking of Brucella is well described, the strategies developed by Brucella to survive and multiply in phagocytic and non-phagocytic cells, particularly to access nutriments during its intracellular journey, are still largely unknown. Metabolism and virulence of Brucella are now considered to be two sides of the same coin. Mechanisms presiding to the colonization of the pregnant uterus in different animal species are not known. Vaccination is the cornerstone of control programs in livestock and although the S19, RB51 (both in cattle) and Rev 1 (in sheep and goats) vaccines have been successfully used worldwide, they have drawbacks and thus the ideal brucellosis vaccine is still very much awaited. There is no vaccine available for pigs and wildlife. Animal brucellosis control strategies differ in the developed and the developing world. Most emphasis is put on eradication and on risk analysis to avoid the re-introduction of Brucella in the developed world. Information related to the prevalence of brucellosis is still scarce in the developing world and control programs are rarely implemented. Since there is no vaccine available for humans, prevention of human brucellosis relies on its control in the animal reservoir. Brucella is also considered to be an agent to be used in bio- and agroterrorism attacks. At the animal/ecosystem/human interface it is critical to reduce opportunities for Brucella to jump host species as already seen in livestock, wildlife and humans. This task is a challenge for the future in terms of veterinary public health, as for wildlife and ecosystem managers and will need a "One Health" approach to be successful. PMID:21571380

  5. The Rose Bengal Test in human brucellosis: a neglected test for the diagnosis of a neglected disease.

    Directory of Open Access Journals (Sweden)

    Ramón Díaz

    Full Text Available Brucellosis is a highly contagious zoonosis affecting livestock and human beings. The human disease lacks pathognomonic symptoms and laboratory tests are essential for its diagnosis. However, most tests are difficult to implement in the areas and countries were brucellosis is endemic. Here, we compared the simple and cheap Rose Bengal Test (RBT with serum agglutination, Coombs, competitive ELISA, Brucellacapt, lateral flow immunochromatography for IgM and IgG detection and immunoprecipitation with Brucella proteins. We tested 208 sera from patients with brucellosis proved by bacteriological isolation, 20 contacts with no brucellosis, and 1559 sera of persons with no recent contact or brucellosis symptoms. RBT was highly sensitive in acute and long evolution brucellosis cases and this related to its ability to detect IgM, IgG and IgA, to the absence of prozones, and to the agglutinating activity of blocking IgA at the pH of the test. RBT was also highly specific in the sera of persons with no contact with Brucella. No test in this study outperformed RBT, and none was fully satisfactory in distinguishing contacts from infected patients. When modified to test serum dilutions, a diagnostic titer >4 in RBT resulted in 87.4% sensitivity (infected patients and 100% specificity (contacts. We discuss the limitations of serological tests in the diagnosis of human brucellosis, particularly in the more chronic forms, and conclude that simplicity and affordability of RBT make it close to the ideal test for small and understaffed hospitals and laboratories.

    Brucellosis is one of the most common and widely spread zoonotic diseases in the world. Control of the disease in humans is dependent upon limiting the infection in animals through surveillance and vaccination. Given the dramatic economic and political changes that have taken place in the former Soviet Union, which have limited control, evaluating the status of human brucellosis in former Soviet states is crucial. We assessed annual spatial and temporal trends in the epidemiology of human brucellosis in Azerbaijan, 1983-2009, in conjunction with data from a livestock surveillance and control programme (2002-2009). To analyse trends, we used a combination of segmented regression and spatial analysis. From 1983 to 2009, a total of 11 233 cases of human brucellosis were reported. Up to the mid-1990s, the incidence of human brucellosis showed a pattern of re-emergence, increasing by 25% annually, on average. Following Soviet governance, the incidence rates peaked, increasing by 1.8% annually, on average, and subsequently decreasing by 5% annually, on average, during the period 2002-2009. Despite recent national declines in human incidence, we identified geographic changes in the case distribution characterized by a geographic expansion and an increasing incidence among districts clustered in the south-east, compared to a decrease of elsewhere in the country. Males were consistently, disproportionately afflicted (71%) and incidence was highest in the 15 to 19 age group (18.1 cases/100 000). During the period 2002-2009, >10 million small ruminants were vaccinated with Rev1. Our findings highlight the improving prospects for human brucellosis control following livestock vaccination; however, the disease appears to be re-emerging in south-eastern Azerbaijan. Sustained one health measures are needed to address changing patterns of brucellosis in Azerbaijan and elsewhere in the former Soviet Union. PMID:26403990

Materials and Methods: Total 1000 serum samples comprising of 485 from sheep and 515 from goat tested for detection of antibodies against the Brucella species by three different serological tests viz., Rose bengal plate test (RBPT, Standard tube agglutination test (STAT, and Indirect Enzyme-linked immunosorbent assay (I-ELISA. Results: The seroprevalence of brucellosis in small ruminants was 11.30%, 11.10%, and 8.80% by RBPT, STAT, and I-ELISA, respectively. The seroprevalence of brucellosis was found to be higher in sheep than goats. The sensitivity of RBPT was found slight more than STAT, but the specificity of both tests was same. In this study, the overall agreement of RBPT and STAT with I-ELISA was found 92.50% and 92.30% in small ruminants, respectively. Conclusion: I-ELISA was a better serological test as compared to RBPT and STAT in the sense of sensitivity, specificity, and rapidity and it could be advocated for screening of brucellosis in sheep and goats.

    Full Text Available A survey to estimate the seroprevalence of ovine and caprine brucellosis was conducted in the region of Trás-os-Montes e Alto Douro, Northeast of Portugal. In total, 278,097 small ruminants and 5,466 flocks from 13 Livestock Farmers Organizations (OPP's were analysed. Four hundred and eighty seven (8.9% flocks had one or more serologically positive animals with values ranging between 8.2% and 9.7%. The individual seroprevalence was 0.44% (CI 95% 0.40-0.48%. There were significant differences in seroprevalence rates among herd sizes, species, constitution of herd, production's type and OPP. Based on the results of this survey, a small percentage of animals and a high percentage of flocks in the Northeast of Portugal were serologically positive. Considering the paucity of epidemiological reports on brucellosis in the Northeast of Portugal the information on seroprevalence provided in this study is necessary to define control measures for brucellosis in the area.

    Between 2005 and 2006, a cross-sectional survey was carried out in domestic ruminants in agropastoral communities of Serengeti district, Tanzania to determine the seroprevalence of brucellosis in domestic-wildlife interface villages. Both the Rose Bengal Plate Test (RBPT) and Competitive Enzyme Linked-immunosorbent Assay (c-ELISA) were used to analyse 82 human and 413 livestock sera from four randomly selected villages located along game reserve areas of Serengeti National Park. Although both cattle (288) and small ruminants (125) were screened, seropositivity was detected only in cattle. The overall seroprevalence based on c-ELISA as a confirmatory test was 5.6%. In cattle both age and sex were not statistically associated with brucellosis seropositivity (P = 0.63; 95% CI = 0.03, 0.8 and 0.33; 95% CI = 0.6, 3.7, respectively). Overall herd level seropositivity was 46.7% (n = 7), ranging from 25% to 66.7% (n = 4-10). Each village had at least one brucellosis seropositive herd. None of the 82 humans tested with both RBPT and c-ELISA were seropositive. Detecting Brucella infection in cattle in such areas warrants further investigation to establish the circulating strains for eventual appropriate control interventions in domestic animals.

    To date, detection of antibodies against the lipopolysaccharide portion is the backbone of most serodiagnostic methods for brucellosis screening. However this pose a risk for false positive reactions related to other pathogens especially that of Yersinia enterocolitica O:9 which has the most prominent cross reactivity with Brucella spp. In this study, cloning and expression of Brucella abortus bacterioferritin (Bfr) was accomplished by PCR amplification into an expression vector system, and purification of a recombinant B. abortus Bfr (rBfr). The immunogenicity of rBfr was confirmed by Western blot with Brucella-positive bovine serum. To determine whether rBfr has a potential benefit for use in the serodiagnosis of bovine brucellosis, rBfr-based ELISA was performed. Interestingly, rBfr was able to detect anti-Brucella antibodies in positive sera in a dependent manner of TAT values but did not show an immunoreaction with negative samples. Particularly, average OD492 values at the lowest, medium and highest TAT titer levels were 1.4, 2.2 and 2.6-fold increase compared with the cutoff value, respectively. The accuracy, specificity and sensitivity of rBfr showed 89.09%, 93.6% and 85.33%, respectively. These findings suggest that rBfr might be a good candidate for serological diagnosis development of bovine brucellosis. PMID:27012915

    2013-05-01

    Brucellosis, a frequent bacterial zoonosis, can produce debilitating chronic disease with involvement of multiple organs in human patients. Whereas acute brucellosis is well studied using the murine animal model, long-term complications of host-pathogen interaction remain largely elusive. Human brucellosis frequently results in persistent, chronic osteoarticular system involvement, with complications such as arthritis, spondylitis and sacroiliitis. Here, we focused on identifying infectious sites in the mouse that parallel Brucella melitensis foci observed in patients. In vivo imaging showed rapid bacterial dispersal to multiple sites of the murine axial skeleton. In agreement with these findings, immunohistochemistry revealed the presence of bacteria in bones and limbs, and in the lower spine vertebrae of the axial skeleton where they were preferentially located in the bone marrow. Surprisingly, some animals developed arthritis in paws and spine after infection, but without obvious bacteria in these sites. The identification of Brucella in the bones of mice corroborates the findings in humans that these osteoarticular sites are important niches for the persistence of Brucella in the host, but the mechanisms that mediate pathological manifestations in these sites remain unclear. Future studies addressing the immune responses within osteoarticular tissue foci could elucidate important tissue injury mediators and Brucella survival strategies.

    The incidence of Brucella canis infection in humans is unknown in Turkey. In this study, we investigated the prevalence of B. canis infection in human sera obtained from six regions in Turkey and comparatively evaluated the results obtained by agglutination-based techniques using standardized antigens made from B. canis. The patients (n = 1,746) presented with clinical symptoms that were similar to those of brucellosis. All patients who tested negative in the Rose Bengal test for the smooth Brucella strains (abortus, melitensis, and suis) were screened for evidence of B. canis infection using the rapid slide agglutination test (RSAT), the microagglutination test (MAT), and the 2-mercaptoethanol RSAT test (2ME-RSAT). Of the samples tested, 157 (8.9%), 68 (3.8%), and 66 (3.7%) were positive for B. canis, as determined by RSAT, MAT, and 2ME-RSAT, respectively. The diagnostic sensitivity, specificity, positive predictive value, and negative predictive value of RSAT were 100%, 94.6%, 42%, and 100%, respectively, and of MAT were 100%, 99.9%, 97%, and 100%, respectively. We recommend the routine use of MAT and 2ME-RSAT to check the sera of all patients with symptoms of brucellosis who are negative for brucellosis using a smooth Brucella antigen. PMID:22116333

Ninety six samples of blood were collected from aborted ewes at different stages of gestation,suspected to be infected with toxoplasmosis and /or brucellosis from different regions in Nineveh governorate. The percentageof toxoplasma and brucella infection depending on Latex Agglutination Test (LAT and Rose Bengal Test were 21.88% and23.96% respectively. The results of biochemical analysis showed that infection with toxoplasma caused significant elevation ofserum activities of aspartate aminotransferase (AST, alanine aminotransferase (ALT and lactate dehydrogenase (LDH. Aswell as the concentrations of glucose, total protein and copper. Where as the activity of alkaline phosphatase (ALP and theconcentration of calcium and zinc were reduced. Infection with brucellosis caused a significant increased in serum AST, ALTand LDH, ALP and creatin phosphokinase (CPK activities, and glucose, zinc and cholesterol concentrations. While serumcalcium and total protein concentration were decreased. Association of toxoplasma and brucella infection induced significantelevation of serum AST, ALT and LDH and CPK activities and the concentrations of glucose and copper with significant reduction in serum ALP activity and both calcium and zinc concentrations. It was concluded from this study that infection ofewes with toxoplasma and/or brucella caused changes in some biochemical parameters in the serum.

    Brucellosis is a worldwide zoonotic disease. Generally, humans can be infected by either the consumption of raw milk and fresh cheeses made from unpasteurised milk or by contact with infected animals, mainly in endemic regions. In this study, we investigated a brucellosis outbreak in State of Guanajuato, an endemic region of Mexico. Microbiological culture of human blood, raw milk from cows and goats, and fresh cheeses was performed to isolate Brucella. Identification of the bacteria was done by bacteriological procedures and by multiplex Bruce-ladder polymerase chain reaction (PCR). Brucella melitensis was isolated from patients, infected goats, and fresh goat cheeses; while Brucella abortus was isolated from cows. All patients had eaten fresh cheese, but no occupational exposure to animals was reported. The results of molecular typing did not show any Brucella vaccine strains. The isolation, identification, and molecular characterisation of Brucella spp. in both human brucellosis cases and infected animals are very important to identify the source of infection and to take control measures in endemic regions.

    We evaluated livestock owners' knowledge, attitudes, and practices regarding brucellosis in Jordan. A questionnaire was administered and biological samples were examined to verify the serological status of animals. Seroprevalence estimates indicated that 18.1% (95% CI: 11-25.3) of cattle herds and 34.3% (95% CI: 28.4-40.4) of small ruminant flocks were seropositive. The results showed that 100% of the interviewed livestock keepers were aware of brucellosis: 87% indicated a high risk of infection if unpasteurized milk is consumed and 75% indicated a high risk if unpasteurized dairy products are consumed. Awareness of the risk of infection through direct contact with fetal membranes or via physical contact with infected livestock is considerably lower, 19% and 13%, respectively. These knowledge gaps manifest in a high frequency of high-risk practices such as assisting in animal parturition (62%), disposing aborted fetuses without protective gloves (71.2%) or masks (65%), and not boiling milk before preparation of dairy products (60%). When brucellosis is suspected, basic hygiene practices are often disregarded and suspect animals are freely traded. Public health education should be enhanced as the disease is likely to remain endemic in the ruminant reservoir as long as a suitable compensation program is not established and trust on available vaccines is regained.

    Full Text Available ABSTRACT: Introduction & Objective: Brucellosis is a zoonotic disease that may have a major public health and economic impact in most countries. The disease appears as a Malt fever in humans and abortion in animals. This study was designed to determine the serologic titer of Brucella in high risk and non high risk people in Boyerahmad. Materials & Methods: A retrospective seroepidemiological study was performed on samples collected from 604 high risk and non high risk people using Rose Bengol test, tube standard test as a rapid test and 2 mercaptoethanol (2ME and comb's wright as a confirmatory test. The data collected were analyzed by X2 test via SPSS. Results: Seroprevalence of Brucellosis in high risk people appeared to be high in the Rose Bengal and tube standard test (TST 6.62 at titer ≥1/40 whereas for non high risk it was 0%. Confirmation test in high risk people was shown with 2ME in four people. Conclusion: Brucellosis is a major cause of disease in high risk people which can be due to direct or indirect contact with diary products of the related animals.

    Full Text Available During September-December, 1990 to 1994, serum samples from a total of 5792 semi-domesticated reindeer (Rangifer tarandm tarandm from Finnmark county, northern Norway, were screened for brucellosis on an indirect ELISA. There were no serologically positive animals. Twenty six of the animals had levels of antibodies detectable on the ELISA and were classed as suspicious, but the ELISA optical density readings were low compared to the readings for reindeer that were both culture positive and seropositive for Brucella suis biovar 4. When assayed on the standard tube agglutination test (STAT, all the 26 animals were seronegative. When absorbed with cells of Yersinia enterocolitica 0-9, the antibody detectable on the ELISA could be removed to a great extent from most of the sera, indicating previous or ongoing exposure to bacteria serologically cross-reacting with Brucella in these animals. We concluded that brucellosis was not present among reindeer in Finnmark during this study. This is supported by the absence of any reports of brucellosis among reindeer in Norway.

    Full Text Available Between 2005 and 2006, a cross-sectional survey was carried out in domestic ruminants in agropastoral communities of Serengeti district, Tanzania to determine the seroprevalence of brucellosis in domestic–wildlife interface villages. Both the Rose Bengal Plate Test (RBPT and Competitive Enzyme Linked-immunosorbent Assay (c-ELISA were used to analyse 82 human and 413 livestock sera from four randomly selected villages located along game reserve areas of Serengeti National Park. Although both cattle (288 and small ruminants (125 were screened, seropositivity was detected only in cattle. The overall seroprevalence based on c-ELISA as a confirmatory test was 5.6%. In cattle both age and sex were not statistically associated with brucellosis seropositivity (P = 0.63; 95% CI = 0.03, 0.8 and 0.33; 95% CI = 0.6, 3.7, respectively. Overall herd level seropositivity was 46.7% (n = 7, ranging from 25% to 66.7% (n = 4–10. Each village had at least one brucellosis seropositive herd. None of the 82 humans tested with both RBPT and c-ELISA were seropositive. Detecting Brucella infection in cattle in such areas warrants further investigation to establish the circulating strains for eventual appropriate control interventions in domestic animals.

  20. Evaluation of an indirect elisa for the diagnosis of bovine brucellosis in Patagonia, Argentina

    International Nuclear Information System (INIS)

    Control and eradication of bovine brucellosis is usually based on the serological detection of antibodies. In Argentina, the Rose Bengal test (RB) and the Buffered Plate antigen test (BPA) are the two screening test officially recognized, while the 2-mercaptoethanol test (2ME) and the Tube Agglutination test (SAT) are the confirmatory assays currently in use. In order to improve the serological diagnosis of bovine brucellosis in Patagonia, Argentina, an indirect ELISA kit produced by the Joint FAO/IAEA Division was evaluated. Sera from negative non-vaccinated, negative but vaccinated and positive animals were tested by all the above techniques. The specificity of the I-ELISA (99.6% and 99.7%) was similar to that of the BPA, RB, 2ME and Complement Fixation test (CF) when used to test sera from non-vaccinated, negative and vaccinated, negative animals, respectively. The sensitivity of the I-ELISA (98%) was higher than the BPA test (96%) and the CF test (95,2%). The I-ELISA kit evaluated in this study was thought to be a valuable tool for the diagnosis of bovine brucellosis in Patagonia region where little epidemiological information is available about this disease and where large numbers of sera should be tested to obtain such information.

    Full Text Available AbstractBackground and objective: Brucellosis is a zoonosis transmittable to humans poses a significant public health problem in many developing countries and requires rapid and accurate diagnostic methods. Here, our aim was to develop a diagnostic polymerase chain reaction (PCR assay in artificially contaminated serum samples as a model for rapid and accurate laboratory confirmation of human brucellosis. Material and methods: In this study, initially the standard Brucella abortus strain (2308 were cultured on Brucella agar medium and then colonies were inactivated by formalin 10 %. Genomic DNA was extracted from inactivated bacterial colonies. Serial dilutions of bacterial-DNA were prepared in fetal bovine serum (FBS and water and subsequently DNA extraction were repeated on these artificially contaminated samples. The two pairs of primers amplified two different fragments included in: a gene encoding an outer membrane protein (omp-2 (primers JPF/JPR and a sequence 16S rRNA of B. abortus (primers F4/R2. Results: The two primers assayed showed a difference in sensitivity for detecting Brucella DNA, ranging between 5 pg and 50 pg for artificially contaminated serum samples and 50Fg and 5 pg for contaminated control samples. Therefore, the sensitivity of PCR using F4/R2 primers was greater than the PCR using JPF/JPR primers.Conclusion: Although the sensitivity of PCR using these primers was affected by serum inhibitors, they are still the most sensitive and they could provide a useful tool for the diagnosis of human brucellosis.

    Background Although brucellosis (Brucella spp.) and Q Fever (Coxiella burnetii) are zoonoses of global importance, very little high quality data are available from West Africa. Methods/Principal Findings A serosurvey was conducted in Togo’s main livestock-raising zone in 2011 in 25 randomly selected villages, including 683 people, 596 cattle, 465 sheep and 221 goats. Additionally, 464 transhumant cattle from Burkina Faso were sampled in 2012. The serological analyses performed were the Rose Bengal Test and ELISA for brucellosis and ELISA and the immunofluorescence assay (IFA) for Q Fever Brucellosis did not appear to pose a major human health problem in the study zone, with only 7 seropositive participants. B. abortus was isolated from 3 bovine hygroma samples, and is likely to be the predominant circulating strain. This may explain the observed seropositivity amongst village cattle (9.2%, 95%CI:4.3–18.6%) and transhumant cattle (7.3%, 95%CI:3.5–14.7%), with an absence of seropositive small ruminants. Exposure of livestock and people to C. burnetii was common, potentially influenced by cultural factors. People of Fulani ethnicity had greater livestock contact and a significantly higher seroprevalence than other ethnic groups (Fulani: 45.5%, 95%CI:37.7–53.6%; non-Fulani: 27.1%, 95%CI:20.6–34.7%). Appropriate diagnostic test cut-off values in endemic settings requires further investigation. Both brucellosis and Q Fever appeared to impact on livestock production. Seropositive cows were more likely to have aborted a foetus during the previous year than seronegative cows, when adjusted for age. This odds was 3.8 times higher (95%CI: 1.2–12.1) for brucellosis and 6.7 times higher (95%CI: 1.3–34.8) for Q Fever. Conclusions This is the first epidemiological study of zoonoses in Togo in linked human and animal populations, providing much needed data for West Africa. Exposure to Brucella and C. burnetii is common but further research is needed into the clinical

    Full Text Available Human brucellosis has reemerged as a serious public health threat to the Bedouin population of southern Israel in recent years. Little is known about its economic implications derived from elevated healthcare utilization (HCU. Our objective was to estimate the HCU costs associated with human brucellosis from the insurer perspective. A case-control retrospective study was conducted among Clalit Health Services (CHS enrollees. Brucellosis cases were defined as individuals that were diagnosed with brucellosis at the Clinical Microbiology Laboratory of Soroka University Medical Center in the 2010-2012 period (n = 470. Control subjects were randomly selected and matched 1:3 by age, sex, clinic, and primary physician (n = 1,410. HCU data, demographic characteristics and comorbidities were obtained from CHS computerized database. Mean±SD age of the brucellosis cases was 26.6±17.6 years. 63% were male and 85% were Bedouins. No significant difference in Charlson comorbidity index was found between brucellosis cases and controls (0.41 vs. 0.45, respectively, P = 0.391. Before diagnosis (baseline, the average total annual HCU cost of brucellosis cases was slightly yet significantly higher than that of the control group ($439 vs. $382, P<0.05, however, no significant differences were found at baseline in the predominant components of HCU, i.e. hospitalizations, diagnostic procedures, and medications. At the year following diagnosis, the average total annual HCU costs of brucellosis cases was significantly higher than that of controls ($1,327 vs. $380, respectively, P<0.001. Most of the difference stems from 7.9 times higher hospitalization costs (p<0.001. Additional elevated costs were 3.6 times higher laboratory tests (P<0.001, 2.8 times higher emergency room visits (P<0.001, 1.8 times higher medication (P<0.001 and 1.3 times higher diagnostic procedures (P<0.001. We conclude that human brucellosis is associated with elevated HCU costs. Considering these

  5. Development of a new live rough vaccine against bovine brucellosis

    International Nuclear Information System (INIS)

    Full text: Brucella abortus S-19 is the most commonly used attenuated live vaccine to prevent bovine brucellosis. The vaccine induces good levels of protection in cattle, preventing premature abortion. Although B. abortus S-19 is the most used vaccine in eradication campaigns worldwide, it has two major problems: (i) it produces abortion when administered to pregnant cattle and is fully virulent for humans and (ii), the presence of smooth lipopolysaccharide interferes with the discrimination between infected and vaccinated animals during immunescreening procedures. In our laboratory we have previously cloned, sequenced and disrupted the gene coding for the enzyme phosphoglucomutase (pgm), responsible for the interconversion of glucose-6P to glucose-1P. The mutant does not synthesize the sugar nucleotide UDP-glucose and/or ADP-glucose and thus is unable to form any polysaccharide containing glucose, galactose or any other sugars whose synthesis proceeds through a glucose-nucleotide intermediate. The mutant has a rough phenotype, is avirulent in mice but retains the ability to multiply inside HeLa cells, although it shows a delay of the exponential intracellular replication. These characteristics prompt us to evaluate the potential use of this strain as a new live rough vaccine. We generated an unmarked deletion mutant of pgm. Western blot analysis of purified lipopolysaccharide from Δpgm indicated that it is devoid of O-antigen, however Δpgm whole cell extracts contained detectable amounts of O-antigen with a MW of 45 kDa, indicating that mutant strain is able to synthesize O-antigen but incapable to assemble a complete LPS probably due to the presence of an altered core structure. When administered intraperitoneally in Balb/C mice, the number of viable Δpgm recovered from spleens were, at all tested times, significantly lower than those inoculated with the parental virulent strain S2308 and was completely cleared at 8 weeks p.i., thus indicating a severe

    Full Text Available In endemic area the most challenging problem for brucellosis is to find a reliable diagnostic method. In this case-control study, we investigated the accuracy of ELISA test for diagnosis of human brucellosis and determined the optimal cut-off value for ELISA results in Iran. The laboratory diagnosis of brucellosis was performed by blood isolation of Brucella organism with a BACTEC 9240 system and/or detection of Brucella antibodies by standard agglutination test (titer ≥ 1:160. Serum level of ELISA IgG and ELISA IgM from 56 confirmed cases of brucellosis and 126 controls were compared with each other by Box plot graph and Receiver Operating Characteristic (ROC curve. Box plot graphs showed the high degree of dispersion for IgG and IgM data in patients compared with all controls. We observed partially overlapping for IgM data (not for IgG between cases and controls in graphs. The area under ROC curve for distinguishing between cases and controls was larger for IgG compared to IgM. Based on results of this study, ELISA IgG test was more reliable than ELISA IgM test in diagnosis of human brucellosis in Iran. Using a cut-off of 10 IU/ml and 50 IU/ml had most sensitivity (92.9% and most specificity (100% for ELISA IgG test, respectively.

    Zoonotic diseases can be occupational hazards to people who work in close contact with animals or their carcasses. In this cross-sectional study, 190 sera were collected from butchers and slaughterhouse workers in different regions of the Sistan va Baluchestan province, in Iran in 2011. A questionnaire was filled for each participant to document personal and behavioural information. The sera were tested for detection of specific IgG antibodies against brucellosis, leptospirosis, and Q fever (phase I and II) using commercial enzyme-linked immunosorbent assays (ELISA). The seroprevalence of brucellosis was 7.9%, leptospirosis 23.4%, and phase I and II of Q fever were 18.1% and 14.4%, respectively. The seroprevalence of Q fever and leptospirosis, but not brucellosis, varied among regions within the province (p = 0.01). Additionally, a significant relationship was found between seropositivity of Q fever and camel slaughtering (p = 0.04). Reduced seropositivity rate of brucellosis was associated with use of personal protective equipment (PPE) (p = 0.004). This study shows that brucellosis, leptospirosis and Q fever occur among butchers and slaughterhouse workers in this area. PMID:26731333

  10. Ruminant brucellosis in the Kafr El Sheikh Governorate of the Nile Delta, Egypt: prevalence of a neglected zoonosis.

    Directory of Open Access Journals (Sweden)

    Yamen M Hegazy

    Full Text Available BACKGROUND: Brucellosis is a neglected tropical zoonosis allegedly reemerging in Middle Eastern countries. Infected ruminants are the primary source of human infection; consequently, estimates of the frequency of ruminant brucellosis are useful elements for building effective control strategies. Unfortunately, these estimates are lacking in most Middle East countries including Egypt. Our objectives are to estimate the frequency of ruminant brucellosis and to describe its spatial distribution in Kafr El Sheikh Governorate, Nile Delta, Egypt. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a cross-sectional study in which 791 sheep, 383 goats, 188 cattle milk tanks and 173 buffalo milk tanks were randomly selected in 40 villages and tested for the presence of antibodies against Brucella spp. The seroprevalence among different species was estimated and visualized using choropleth maps. A spatial scanning method was used to identify areas with significantly higher proportions of seropositive flocks and milk tanks. We estimated that 12.2% of sheep and 11.3% of goats in the study area were seropositive against Brucella spp. and that 12.2% and 12% of cattle and buffalo milk tanks had antibodies against Brucella spp. The southern part of the governorate had the highest seroprevalence with significant spatial clustering of seropositive flocks in the proximity of its capital and around the main animal markets. CONCLUSIONS/ SIGNIFICANCE: Our study revealed that brucellosis is endemic at high levels in all ruminant species in the study area and questions the efficacy of the control measures in place. The high intensity of infection transmission among ruminants combined with high livestock and human density and widespread marketing of unpasteurized milk and dairy products may explain why Egypt has one of the highest rates of human brucellosis worldwide. An effective integrated human-animal brucellosis control strategy is urgently needed. If resources are not

    Full Text Available Introduction: Brucellosis is a zoonotic infection. Metabolism of trace elements such as zinc and copper can influence the response of immunity system and can activate host 's immunochemical mechanisms against the organism. Therefore, this study aimed to determine changes in serum levels of Zn and Cu in patients with brucellosis in pre and post treatment compared with healthy persons. Methods: In this individual matched case-control study, 26 patients participated who were admitted to infectious unit of Farshchian Hospital with brucellosis. Moreover, 26 healthy individuals were included in the control group. 5mL of venous blood was taken from all cases in pre-treatment as well post-treatment. Then, the serum samples were diluted with deionized water, and Cu and Zn levels were measured by using Atomic Absorption Spectrophotometer. Results: In this study, 26 patients with brucellosis were enrolled, who were 13 men (50% and 13 women (50%. No significant difference was observed between the patients and the control group in regard with their age and sex. Serum level of Cu in patients with brucellosis was found to be 100.31µg/dl and 92.81µg/dl, respectively before and after the treatment (P=0.495. Serum level of Cu in healthy individuals was reported to be 97.96µg/dl. In addition, serum level of Zn in the patients and controls was 93 µg/dl and 96.38 µg/dl, respectively (P= 0.625. Patients' Zn Serum level was found to be 90.27µg/dl after the treatment. Conclusion: In this study, no significant changes were observed in serum levels of copper and zinc in the patients with brucellosis in comparison with the control group. Besides, no significant changes were reported in serum levels of these elements in the patients in the end of treatment.

    Full Text Available Background: Different serological tests are used in serologic diagnosis of brucellosis. The most widely used of these are Standard Tube Agglutination and Coombs anti-brucella tests. Whereas ELISA Ig M and Ig G tests have been in use for a long time, immuncapture agglutination test has been recently introduced and used in serological diagnosis. The aim of this study was to compare diagnostic values of ELISA Ig M and Ig G and immuncapture agglutination tests with Coombs anti-brucella test.Methods: Sera from 200 patients with presumptive diagnosis of brucellosis were included into the study. Coombs anti-brucella test, ELISA Ig M and Ig G tests and Immuncapture test were investigated in these sera. Then, sensitivity, specificity, negative predictive and positive predictive values were calculated.Results: Sensitivity, specificity, negative predictive and positive predictive values were found to be 90,6 %, 76,3 %, 94,2 %, and 65,9 % respectively for the Immuncapture test, whereas they were found to be 73,7 %, 58,9 %, 84,2 %, and 42,8 % for Ig G and 72,2 %, 67,8 %, 85,2 %, and 48,7 % for Ig M. The Immuncapture test was found to be compatible with ELISA Ig M and Ig G tests but it was statistically incompatible with Coombs anti-brucella test.Conclusions: Immuncapture agglutination test yields similar results to those of Coombs anti-brucella test. This test is a useful test by virtue of the fact that it determines blocking antibodies in the diagnosis and follow-up of brucellosis.

    Introduction: Brucellosis is a zoonotic infectious disease that remains endemic in developing countries. The purpose of this study is to emphasize the need for considering brucellosis as a diagnosis, since this disease has a high risk of complications among young patients when not treated appropriately. Methodology: A total of 88 brucellosis cases with blood cultures that were positive for the pathogen were evaluated retrospectively in this study. Results: The patients included 33 males (37.5%) and 55 females (62.5%) with a median age of 8.9 years (range: 5-14 years). A total of 43.1% (n=38) of the cases included occupational exposure to animals as a possible infection source. The consumption of raw milk products, especially cheese, was present in 52.2% (n=46) of the cases. Clinically, 55 of the cases were acute (62.5%), 23 of the cases were subacute (26.2%) and 10 of the cases were chronic (11.3%). The distribution of the joint pain complaints was as follows: 62.5% (n=55) of patients reported hip pain, 22.7% (n=20) of patients reported knee pain, 11.4% (n=10) of patients reported lumbar-back pain and 3.4% (n=3) of patients reported pain in other joints. A total of 59.1% (n=52) of the cases had been examined by another doctor at least once and mistreated. Conclusion: Complication rates and the rate of chronic infection increase with delayed diagnosis, and clinical doubt is the most important criterion for diagnosis, particularly in endemic regions.

    Full Text Available A retrospective serosurvey was carried out between 2009 and 2012 to detect antibodies to Brucella spp. in free-ranging African wildlife ungulates from five selected game parks in Zimbabwe. Samples were drawn from wildlife-livestock interface and non-interface areas in Zimbabwe. A total of 270 serum samples from four different species, namely African buffalo (Syncerus caffer (n=106, impala (Aepyceros melampus (n = 72, black rhinoceros (Diceros bicornis (n= 45 and white rhinoceros (Ceratotherium simum (n = 47, were tested. The percentage of positive samples was 17.0% in buffalo (18/106; 95% CI: 9.72% – 24.1% and 1.4% in impala (1/72; 95% CI: 0% – 4.2%. No antibodies to Brucella spp. were detected in the two rhinoceros species. The difference in the percentage of seropositive cases between buffalo and impala was significant (p< 0.05. Seropositivity to Brucella spp. was higher (19.1% in adult buffalo compared with juveniles and sub-adults younger than six years (5.9%. Further, seropositivity was marginally higher (20.4% in animals from wildlife-livestock interface areas than in those from non-interface areas (13.45%; OR = 1.45 although the difference was not statistically significant. The study showed that brucellosis could be more widespread in buffalo and may circulate in this species independently in the absence of contact with cattle, whilst rhinoceros may be considered less susceptible to brucellosis. The role of the wildlife-livestock interface in the epidemiology of brucellosis in wildlife and livestock is probably overstated but needs to be explored further.

    Full Text Available Aim: Brucellosis is an endemic and zoonotic disease in livestock farming areas. Patients may exhibit relapses, reinfections and multi-system complications. Therefore, early diagnosis, appropriate treatment as well as serological follow-up are extremely important in the management of this disease. Methods: We aimed to investigate the demographic characteristics, clinical and laboratory findings and risk factors in 50 brucellosis cases (14 males, 36 females who were treated in Hakkari State Hospital. All patients were evaluated for post-treatment serological results. Results: The mean age of the patients was 35 years. The main clinical symptoms were arthralgia, fatigue, sweating, back pain, and headache. Fever, hepatomegaly, splenomegaly and arthritis were the most common signs. Anemia, high level of AST and ALT, leukopenia, thrombocytopenia, high sedimentation rate, and leukocytosis were found in laboratory tests. The Wright agglutination test was positive at titers of 1/160 in 18 cases, 1/320 in 22 cases, 1/640 in 3 cases, and 1/1280 in 7 cases. Twelve patients had relapse. One patient, who was a veterinarian, was infected via splashing live brucella vaccine into the eyes. Two women transmitted the disease to their babies through breast milk. At the end of the treatment, Wright agglutination test results were negative in all patients. Conclusion: The average duration of symptoms before the diagnosis was 4 months in our study. Therefore, brucellosis should be considered in all individuals who present with fever and arthralgia in endemic areas (The Medical Bulletin of Haseki 2015; 53:139-42

    Full Text Available In order to get a reliable estimate of brucellosis prevalence in Eritrean dairy cattle, a cross-sectional study was carried out in 2009. The survey considered the sub-population of dairy cattle reared in modern small- and medium-sized farms. Samples were screened with the Rose Bengal test (RBT and positive cases were confirmed with the complement fixation test (CFT. A total of 2.77%(417/15 049; Credibility Interval CI: 2.52% – 3.05% of the animals tested in this study were positive for antibodies to Brucellaspecies, with a variable and generally low distribution of positive animals at regional level. The highest seroprevalence was found in the Maekel region (5.15%; CI: 4.58% – 5.80%, followed by the Debub (1.99%; CI: 1.59% – 2.50% and Gash-Barka (1.71%; CI: 1.34% – 2.20% regions. Seroprevalence at sub-regional levels was also generally low, except for two sub-regions of Debub and the sub-region Haicota from the Gash-Barka region. Seroprevalence was high and more uniformly distributed in the Maekel region, namely in the Asmara, Berik and Serejeka sub-regions. Considering the overall low brucellosis prevalence in the country, as identified by the present study, a brucellosis eradication programme for dairy farms using a test-and-slaughter policy would be possible. However, to encourage the voluntary participation of farmers to the programme and to raise their awareness of the risks related to the disease for animals and humans, an extensive public awareness campaign should be carefully considered, as well as strict and mandatory dairy movement control.

  17. Probable causes of increasing brucellosis in free-ranging elk of the Greater Yellowstone Ecosystem

    While many wildlife species are threatened, some populations have recovered from previous overexploitation, and data linking these population increases with disease dynamics are limited. We present data suggesting that free-ranging elk (Cervus elaphus) are a maintenance host for Brucella abortus in new areas of the Greater Yellowstone Ecosystem (GYE). Brucellosis seroprevalence in free-ranging elk increased from 0-7% in 1991-1992 to 8-20% in 2006-2007 in four of six herd units around the GYE. These levels of brucellosis are comparable to some herd units where elk are artificially aggregated on supplemental feeding grounds. There are several possible mechanisms for this increase that we evaluated using statistical and population modeling approaches. Simulations of an age-structured population model suggest that the observed levels of seroprevalence are unlikely to be sustained by dispersal from supplemental feeding areas with relatively high seroprevalence or an older age structure. Increases in brucellosis seroprevalence and the total elk population size in areas with feeding grounds have not been statistically detectable. Meanwhile, the rate of seroprevalence increase outside the feeding grounds was related to the population size and density of each herd unit. Therefore, the data suggest that enhanced elk-to-elk transmission in free-ranging populations may be occurring due to larger winter elk aggregations. Elk populations inside and outside of the GYE that traditionally did not maintain brucellosis may now be at risk due to recent population increases. In particular, some neighboring populations of Montana elk were 5-9 times larger in 2007 than in the 1970s, with some aggregations comparable to the Wyoming feeding-ground populations. Addressing the unintended consequences of these increasing populations is complicated by limited hunter access to private lands, which places many ungulate populations out of administrative control.

    Since 1998, there has been a steady decline in herd restrictions and de-populations in Ireland due to bovine brucellosis. There is concern that the interpretation of laboratory results may become increasingly problematic, as brucellosis prevalence falls in Ireland. Therefore, the purpose of the current study was to evaluate the infection status of Irish herds and animals with inconclusive serological evidence of bovine brucellosis. During 12 months from September 1, 2004, laboratory and observational epidemiological data were collected from all Irish herds where animal testing identified at least one animal with a complement fixation test (CFT) reading greater than zero and/or a positive result to the indirect enzyme-linked immunosorbent assay (iELISA). Due to the observational nature of the study, we have robust estimates of the relative, but not the absolute, performance of the CFT, iELISA and brucellin skin test (BST). Herds were divided into three categories (Group A, B or C) on the basis of test results at initial assessment. A total of 639 herds were enrolled into the study, and observed for at least two years following enrolment. A rising CFT titre, with a CFT reading of 111 International CFT Units (IU) or greater at the subsequent blood test, was generally associated with herds where other evidence of infection was also available. Knowledge of the CFT reading at the initial and a subsequent blood test proved useful in distinguishing false-positive and true-positive brucellosis results. There was poor correlation between the CFT and iELISA results, and between the CFT and BST results. As a result of this study, national policy has been modified to include re-sampling of all animals with CFT readings of 20 IU or greater. This project has also led to a reduction in the number of herds restricted, as well as restriction duration. It has also contributed to a reduction in the number of herds listed for contiguous tests, and therefore the potential for contiguity

    Brucella abortus strain RB51 vaccine, is an attenuated live bacterial vaccine that was licensed conditionally by the Center for Veterinary Biologics, Veterinary Services, Animal and Plant Health Inspection Service, USDA, on 23 February 1996, for vaccination of cattle in the United States. Accidental human inoculations can occur during vaccination of cattle, and previous live Brucella vaccines designed for cattle have been known to cause brucellosis in humans. The Centers for Disease Control and Prevention (CDC) established passive surveillance for accidental inoculation with the RB51 vaccine in the United States to determine if this veterinary vaccine is associated with human disease, to describe the circumstances of accidental inoculation, to evaluate the potential efficacy of post-exposure chemoprophylaxis, and to develop recommendations for post-exposure management following exposure to RB51. Reports were received from 26 individuals. Accidental exposure to RB51 occurred by needle stick injury in 21 people (81%), conjunctival spray exposure in four (15%), and spray exposure of an open wound in one (4%) individual. At least one systemic symptom was reported in 19 (73%) people, including three (12%) who reported persistent local reactions with systemic involvement. One case required surgery, and B. abortus strain RB51 was isolated from the wound of that individual. Seven cases reported no adverse event associated with accidental exposure. Nine cases reported previous exposure to Brucella vaccines, including one case who also reported a previous diagnosis of brucellosis following exposure to S19 vaccine. Accidental needle stick injuries and conjunctival or open wound exposures of humans with the RB51 vaccine are associated with both local and systemic adverse events in the United States that are consistent with brucellosis; however, it remains undetermined if strain RB51 vaccine can cause systemic brucellosis in humans. Early culture attempts on those exposed and

    This paper investigates private responses to policies that have been proposed to confront a human-wildlife conflict that likely emerged as a result of a management regime designed to address an earlier human-wildlife conflict. The artificial elk feeding which is intended to conserve wildlife and reduce elk predation on cattle forage, now led to the emergence of brucellosis in elk and has allowed it to become endemic, in turn imposing great risk to the livestock. We propose a joint model of wi...

    A systematic review of studies providing frequency estimates of brucellosis in humans and ruminants and risk factors for Brucella spp. seropositivity in humans in the Middle East was conducted to collate current knowledge of brucellosis in this region. Eight databases were searched for peer-reviewed original Arabic, English, French and Persian journal articles; the search was conducted on June 2014. Two reviewers evaluated articles for inclusion based on pre-defined criteria. Of 451 research articles, only 87 articles passed the screening process and provided bacteriological and serological evidence for brucellosis in all Middle Eastern countries. Brucella melitensis and B. abortus have been identified in most countries in the Middle East, supporting the notion of widespread presence of Brucella spp. especially B. melitensis across the region. Of the 87 articles, 49 were used to provide evidence of the presence of Brucella spp. but only 11 provided new knowledge on the frequency of brucellosis in humans and ruminants or on human risk factors for seropositivity and were deemed of sufficient quality. Small ruminant populations in the region show seroprevalence values that are among the highest worldwide. Human cases are likely to arise from subpopulations occupationally exposed to ruminants or from the consumption of unpasteurized dairy products. The Middle East is in need of well-designed observational studies that could generate reliable frequency estimates needed to assess the burden of disease and to inform disease control policies.

    Brucella abortus is a bacterium of brucellosis causing abortion in cattle. The diagnosis of bovine brucellosis mainly relies on serologic tests using smooth lipopolysaccharide (S-LPS) from B. abortus. However, the usefulness of this method is limited by false-positive reactions due to cross-reaction with other Gram-negative bacteria. In the present study, the eryC gene encoding B. abortus d-erythrulose 1-phosphate dehydrogenase, which is involved in the erythritol metabolism in virulent B. abortus strain but is absent from a B. abortus vaccine strain (S19), was cloned. Recombinant EryC was expressed and purified for the evaluation as a diagnostic reagent for bovine brucellosis. Other B. abortus proteins, Omp16, PP26, and CP39 were also purified and their seroreactivities were compared. Recombinant EryC, Omp16, PP26, and PP39 were all reactive to B. abortus-positive serum. The specificity of recombinant Omp16, PP26, CP39, and EryC, were shown to be approximately 98%, whereas that of B. abortus whole cell lysates was shown to be 95%. The sensitivity of Omp16, PP26, CP39, and EryC were 10%, 51%, 64%, and 43%, respectively, whereas that of B. abortus whole cell lysates was 53%. These results suggested that B. abortus EryC would be a potential reagent for diagnosis for bovine brucellosis as a single protein antigen. PMID:20622221

    The present study was carried out to explore the seroprevalence of brucellosis in yaks of North-Eastern hilly yak tracts of Arunachal Pradesh, India. Of 374 animals tested, 23.79, 21.11 and 18.98% were found positive for brucellosis using avidin-biotin ELISA (AB-ELISA), Rose-Bengal plate test (RBPT) and standard tube-agglutination test (STAT), respectively. The relative sensitivity and specificity for STAT were 79.77 and 100%, respectively and the same for RBPT were 88.76 and 100%, respectively in comparison to AB-ELISA. The alarming prevalence as recorded was highest among the yak cows (31.42%) followed by heifers (23.85%) and bulls (8.88%). The immune response in yaks following standard dose of calfhood vaccination with Brucella abortus strain 19 vaccine showed that protective antibody level persisted up to 210 days. This is the first report from India on prevalence of brucellosis and immunization with B abortus strain 19 vaccine in yaks. The present investigation would be a valuable guideline for future control measure and eradication programme of brucellosis in yaks. PMID:18763048

    Full Text Available Introduction: Brucellosis, a serious zoonosis, is a widespread disease in many countries, especially the developing ones, with an annual report of 500,000 new cases to the World Health Organization (WHO. Although successful results have been achieved by the combination therapies recommended by the WHO, their relapse rates have been high, and therefore, the most effective agents with least side-effects are still undetermined. Materials and Methods: An observational study has been prospectively carried out from 2007 to 2010 in the Infectious Clinics of Hashemi-nejad and Imam Reza Hospitals, Mashhad, Iran. In this study, among the patients of brucellosis, whose diseases were recently diagnosed, 50 patients, receiving one of the two common authentic regimens of doxycycline plus rifampin for eight weeks or ciprofloxacin plus rifampin for six weeks, were selected. The diagnosis was based on the presence of signs and symptoms compatible with brucellosis, including a positive Wright and 2ME tests, with titers equal to or more than 1/160 and 1/40 respectively. Results: The cure rate was the same for the groups (P=0.55. However, the relapse rate was much more for the latter (P= 0.02. Conclusion: Doxycycline plus rifampin was considered better than ciprofloxacin plus rifampin for the treatment of acute brucellosis.

    Full Text Available The causal agent of swine brucellosis is Brucella suis. Within the scope of the kinds of Brucella suis, there are five biotypes, but only biotypes 1, 2 and 3 lead to swine infections. Human infections with Brucella suis biotype 2 are rarely registered. Swine brucellosis is widespread all over the world. It has been noted that the incidence of swine population infected with Brucella suis in Western Europe has been increasing during the recent years. The goal of this project was to isolate, identify and typify the causal agent from epididymal puncture performed on a boar with conditions suspicious of brucellosis, using standard microbiological methods. The results of the research show that Brucella suis biotype 2 can be successfully isolated and identified from a sample obtained by means of epididymal puncture of live animals. Therefore, epididymal puncture gives us a certain, reliable and important sample derived from a live animal for a direct diagnostic of boar brucellosis. The above mentioned first isolate of Brucella suis biotype 2 epididymal puncture, has been marked as K-1.

    Full Text Available Background and Objective: One of the proteins shared in all strains of Brucella is 31 kDa surface protein (BCPS31 that could be an appropriate target for immunization and serological diagnosis. Material and Methods: In the present study, BCSP31 produced as a recombinant protein in pET28a (+ expression system was utilized, using ELISA, to detect trace specific antibody (IgG in brucellosis patients' serum that was confirmed by culture. We also evaluated cytokine response of peripheral blood lymphocytes to this protein in the cell culture. Results: The results indicated a significant amount of surface protein antibodies (IgG in the serum of patients with brucellosis. Evaluation of lymphocyte responses to rBCSP31 also showed a significant IL-12 and IFN-γ production in patients’ lymphocyte cultures. Conclusion: These results suggest that BCSP31 can elicit specific humoral and cellular responses during host infection and it can be used in designing immunization and serologic diagnosis systems

    We herein report on a 62-year-old man who presented with symptoms of intermittent fever that persisted after returning from a trip to France. During his trip, he had eaten natural cheese. Although no bacteria could be isolated from blood culture, the serum agglutination test showed a positive antibody titer of 1 : 160 for Brucella canis. The patient responded well to combination antibiotic therapy consisting of gentamicin, rifampicin, and doxycycline, and his symptoms improved. He became antibody-negative after antibiotic therapy. Although the present case may have been a case of B. canis infection, considering the epidemiology of brucellosis in France, serological cross-reactivity with Brucella melitensis infection is also a possibility. Concerns regarding the reemergence of brucellosis have recently been reported in France, and most cases are caused by B. melitensis. Clinicians should be aware of the fact that blood cultures must be incubated for ≥ 21 days for isolation of Brucella and that in Japan, antibody measurement of B. melitensis cannot be performed on a commercial basis.

The most common symptoms and signs were fever (65 percent, sweating (61 percent, arthritis (30.09 percent, sacroilitis (21.5 percent, orchitis (8.2 percent, spondylitis (2-3 percent and endocarditis (1.18. In this survery blood culture for Brucella melitensis became positive in 48.5 percent and bone marrow in 61 percent. Standard tube agglutination was positive in 96 percent (?1.80. Doxycyclin plus Rifampin was the most common regimen we used (37.8 percent. 4 patients died, but just one of those was directly because of Brucella Endocarditis. In this article we have discussed about some interesting cases as well.

  20. Epidemiological study of brucellosis in eight Greek villages using a Computerised Mapping Programme

    International Nuclear Information System (INIS)

    A Computerised Mapping Programme (CMP) was created step by step to cover all the needs of a cross sectional population survey conducted in eight villages of Fokida, a rural area of central Greece. The maps of Greece (boundary) and the topographical maps of the eight villages were created using the CMP. A volunteer sample of 1121 out of 2607 inhabitants of the study area participated in the population survey. The participants were tested for brucellosis using serological tests (ELISA and Rose Bengal) and the intradermal reaction test. A questionnaire was used to obtain information concerning the risk factors for brucellosis. The risk factors found through statistical analysis were occupation (RR: 5.81, p < 0.00001), consumption of raw milk (RR: 1.98, p < 0.001) and unpasteurized fresh cheese (RR: 2.13, p < 0.01). The same factors were indicated by the CMP. The CMP also indicated manure-contaminated playgrounds in residential yards as a potential risk factor for children. The origin and dissemination were delineated using time-space association display. The CMP proved to be a useful tool in this epidemiological study

  1. Comparison of different serological assays for the differential diagnosis of brucellosis

    International Nuclear Information System (INIS)

    Two indirect and two competitive Enzyme-linked immunosorbent assays (I-ELISA102, I-ELISA103, C-ELISA1 and C-ELISA2 respectively) have been evaluated in comparison with traditional test such as Radial Immunodiffusion (RID), Complement Fixation (CF), Rose Bengal Agglutination (RB) and Rivanol agglutination (RV). The sera analysed included 1018 sera obtained from non-vaccinated bovines, 848 sera from brucellosis free herds calf vaccinated with Strain-19, 295 sera obtained from brucellosis free herds adult vaccinated with Strain-19 and 665 sera from Brucella abortus biotype 1 (field strain) infected herds. Cut-off of values calculated by ROC analysis were established for each ELISA. Although all ELISAs fulfilled the requirements for sensitivity and specificity, in our hands C-ELISA2 performed slightly better than the other assays for differentiating infected from vaccinated bovines. The specificity of this test was similar to that of RID assay which is known to have high specificity for differentiating adult vaccinated from infected bovines. The kappa value among the different tests was good and within the limits of reproducibility and performance expected for the different assays. From the different immunoenzymatic assays, the C-ELISA2, which uses LPS as antigen and a monoclonal antibody against the C/Y epitope as competing reagent, seems to be the most promising of the ELISAs and therefore can be recommended for screening a large number of serum samples on a laboratory basis.

    Full Text Available Brucellosis is a disease of animals caused by Brucella species and is transmissible to humans. This study was undertaken to determine the sero-prevalence of the disease in livestock including sheep and goats and camels, in different regions of Abu Dhabi emirate and to identify factors associated with the epidemiology of the disease. A serological study using 6126 blood samples from livestock were obtained from 267 farms (Izaba during the period from January 2009 to December 2010. The Rose Bengal Plate Test and competitive ELISA were used as screening and confirmatory tests, respectively. The overall sero-prevalence of Brucella antibodies was 8.00% and 7.00% detected by the RBPT by c-ELISA respectively. Brucella prevalence was 8.3, 5.9 and 4.7% in Alain, Abu Dhabi and Western region. The prevalence of the disease was higher (8.4% in sheep and goats than (4.4% in camels respectively. The result showed that, the prevalence of brucellosis was significantly higher in females than male (p<0.04 Out of the 267 farms sampled in the study, 147 (55.1% were infected with Brucella There was strong correlation between herd size and prevalence of the disease, very large herds had significantly higher prevalence when compared with small ones. The study revealed light of a size able prevalence among livestock in Abu Dhabi Emirate and the results reflect the necessity of a control program of the disease is needed to be adopted.

    Full Text Available Background: Brucellosis is a major bacterial zoonosis of global importance with the causative organisms of Gram-negative facultative intracellular pathogens. The aims of this study were to standardize two immunoelectrophoretic techniques, rocket and cross immunoelectrophoresis, and compare their results with other conventional serodiagnostic tests.Methods: Sera from 15 sheep, without any history of brucellosis vaccination, infected with Brucella melitensis M16 sub-cutaneously, were employed in a comparison of culture, precipitating, and immunoelectrophoretic tests. A 125 days serologic follow-up was performed after the infection was started. As a reference, these tests also done in the five healthy sheep.Results: The results obtained with the rocket immunoelectrophoresis test correlated very well with those of the cross immunoelectrophoresis, whereas results of other tests such as culture, Rose Bengal, standard tube agglutination and 2-mercaptoethanol seruagglutination tests were inferior.Conclusion: As agglutination test shows cross reaction and a prozone phenomenon, and in blood culture, the bacte-ria is not always detectable, so they are time consuming rocket and cross immunoelectrophoresis are recommended because their results can be obtained in a shorter time.

    Full Text Available OBJECTIVE: The aim of this study is to describe the risk factors associated with the presentation of brucellosis on the spine, and determine the strength of association between these factors. METHODS: The medical records of patients with brucellosis on the spine were analyzed and a spreadsheet was created to compile the following data: age, sex, place of origin and residence, risk factors (exposure at work, consumption of unpasteurized products and comorbidities, clinical presentation (lumbar pain, anorexia, headache, myalgia, fatigue, paresthesia, dysesthesia, muscle weakness, weight loss, fever, affected spine level, presence of abscesses, disease duration (acute, subacute, chronic, laboratory studies (erythrocyte sedimentation rate, C-reactive protein, serology, blood culture, Rose Bengal test, histopathological reports, imaging studies (x-rays, MRI, bone gammagraphy, established treatment (medical and/or surgical, therapeutic failure and sequelae. RESULTS: A total of 17 patients, 10 women (58.8% and seven men (41.2%, were reviewed from January 2007 to January 2011. The group had a mean age of 57.8 years with a standard deviation of +13.91 and age range between 16-74 years. CONCLUSIONS: There is no significant difference between the groups compared with respect to age and sex, however, improvement of the neurological deficit was observed in eight patients who underwent surgical procedure.

  5. Use of non-conventional tests for the diagnosis of brucellosis

    International Nuclear Information System (INIS)

    A number of non-conventional tests to complement traditional diagnostic methods for Brucellosis were established and assessed in order to verify whether the adoption of a panel of methods combined to alternative sampling strategies would increase the possibility of detecting low levels of Brucella spp. antibodies or microorganisms. The diagnostic performance of each test was established by means of reference standards and compared with conventional screening and confirmatory tests under field conditions. Non-conventional tests assessed for detecting Brucella organisms included: an agglutination method using a monoclonal antibody for an early and specific detection of Brucella spp. from colonies, polymerase chain reaction (PCR) for detection of Brucella spp in raw milk. Methods for detecting Brucella spp. antibodies included an ELISA test applied to cow milk, evaluation of milk-ELISA test through repeated sampling and ELISA in milk for the diagnosis of ovine brucellosis. The adopted strategy of repeated milk testing in dairy cows using ELISA increased the chance of identification of positive animals. (author)

    Elemental mercury (Hg) is the only metal which evaporates in room temperature and its inhalation may cause toxicity. Hg poisoning may occur by mishandling the metal, particularly in children who play with it. Wide-spectrum of the clinical presentations of chronic Hg poisoning may cause misdiagnosis, particularly when history of exposure is unknown. We report two cases of accidental Hg poisoning, which initially had been diagnosed and treated for brucellosis. The patients were two brothers (7 and 14 years old) who presented with pain in their lower extremities, sweating, salivation, weight loss, anorexia and mood changes on admission. Meticulous history taking revealed that they had played with a ball of Hg since 3 months before admission. The level of urinary Hg was 125.9 and 54.2 9 g/L in the younger and older brother, respectively (normal ≤25 g/L). The patients were successfully treated by dimercaprol and discharged in good condition 24 days after admission. These cases are being reported to emphasize the importance of acrodynia as a differential diagnosis for brucellosis in endemic areas. PMID:21803782

    Full Text Available Milk production using local cattle breed-types is an age-old practice in Malawi. Although dairy farming is becoming more common as a result of the increasing population and demand for milk and milk products, there is limited knowledge of the farmers’ awareness of zoonotic disease risks, their preventative practices and the disease burden in animals. This study determined dairy farmers’ general knowledge of zoonoses, assessed their risks for infection with zoonotic bovine tuberculosis (bTB and brucellosis, and evaluated farm practices to prevent disease transmission. A questionnaire was drawn up and administered by the authors. It was used to collect information about the knowledge and preventive practices of 140 out of 684 registered dairy farmers at Mzuzu Agricultural Development Division, northern Malawi. During a second visit to 60 out of the 140 farms, a total of 156 and 95 cattle were tested for brucellosis and tuberculosis, respectively. Most farmers (77.1% knew or had heard of zoonotic diseases, whilst 75.0% correctly named at least one zoonotic disease. More survey participants named tuberculosis as a zoonotic disease compared to brucellosis (74.3% versus 2.9%. The most commonly named means of transmission were milk (67.0% and meat (56.0%. Almost all survey participants (96.4% practised at least one farm activity that could lead to potential transmission of brucellosis or bTB, including sale (67.0% and consumption (34.0% of unpasteurised milk. Antibodies against brucellosis were found in 12 cattle (7.7%, whilst one animal (1.1% reacted to the tuberculin skin test. General knowledge about possible transmission of diseases between humans and animals was high, although most farmers practised risk behaviours that could potentially expose the public to milk-borne zoonotic diseases such as brucellosis and bTB. Furthermore, some animals had positive results for brucellosis and tuberculosis tests. Therefore, improvement of zoonotic disease

    Full Text Available Background: Brucellosis is a world-wide disease, which has a diverse clinical manifestation, and its diagnosis has to be proven by laboratory data. Serum agglutination test (SAT is the most-widely used test for diagnosing brucellosis. The enzyme linked immunosorbent assay (ELISA can also determine specific antibody classes against brucella. It is a sensitive, simple and rapid test, which could be an acceptable alternative to SAT with fewer limitations, however, like any other new test it should be further evaluated and standardized for various populations. This study was planned to determine an optimal cut-off point, for ELISA which would offer maximum sensitivity and specificity for the test when compared to SAT.Methods: Four hundred and seven patients with fever and other compatible symptoms of brucellosis were enrolled in the study. Serum agglutination test, 2-Mercaptoethanol test, and ELISA were performed on their sera. Results: The cut-off point of 53 IU/ml of ELISA-IgG yielded the maximal sensitivity and specificity comparing to the other levels of ELISA-IgG, and was considered the best cut off-point of ELISA-IgG to diagnose acute brucellosis. At this cut-off, the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio were 84.09%, 85.38%, 62.20, 94.90, 5.75, 0.18, respectively.Conclusion: The best cut-off point of ELISA-IgG is 53 IU/ml, which yields the maximal sensitivity and specificity to diagnose acute brucellosis.

    Full Text Available Abstract Background This study was carried out to investigate the status of brucellosis in cattle under various management systems in Adamawa, Kaduna and Kano states, northern Nigeria. Using multi-stage sampling, serum samples of 4,745 cattle from 271 herds were tested using the Rose-Bengal plate-agglutination test (RBPT and positives were confirmed using a competitive enzyme-linked immunosorbent assay (c-ELISA. Results Prevalence estimates were calculated by adjusting for sampling weights and where possible for test sensitivity and specificity. Thirty-seven percent of all animals were RBPT positive, and after confirmation with c-ELISA the overall animal-level prevalence, adjusted for sampling weights, was 26.3% (95% CI, 22.1%-31.0%. Of the herds sampled, 210 (77.5%; 95% CI, 68.6%-84.5% had at least one animal positive to both tests; this did not differ significantly between states (P = 0.538. Mean within-herd seroprevalence in positive herds was 30.2% (95% CI, 25.3%-35.1% and ranged from 3.1% to 85.7%.

    Out of a total of 2,368 sheep and 3,156 goats tested against brucellosis by the Brewer's card test in the 5 Mohafadhas of the northern region of Iraq, 0.93% and 4.4% respectively were recorded as positive reactors. The highest incidence (1.36%) among sheep was found in the Kirkuk region while the lowest (0.78%) was in the Mosul (Nineveh) region. Among goats the highest incidence (11.55%) was revealed in the Dukho region while the lowest (1.47%) was in the Sulaimaniya region. The need for more detailed work on the incidence and on the isolation of the local strains, as well as the need for a control programme, is also discussed. PMID:505594

    The article presents the results of urological examination (spermograms and data of ultrasound examination) of 22 patients with chronic brucellosis and diseases of the scrotum (6 patients with orchitis, 16 with orchiepididymitis) before and after conventional therapy (10 patients) and combined treatment with the inclusion of cycloferon (2 courses of 5 intramuscular injection [0.25 g] with an interval of 10 days)--12 patients. It is shown that the administration of cycloferon leads to more effective relief of intoxication symptoms and inflammation in the testes and appendages (reduction of scrotal wall thickness, size of testes and/or adjuncts, and the incidence and severity of hydrocele), and has a positive effect on spermatogenesis (reduction of semen viscosity, the number of white blood cells in semen, sperm agglutination associated with the formation of sperm antibodies in most patients after treatment), as well as reduces the number of exacerbations of chronic orchitis/orchiepididymitis by 2.4 times.

    Among 82 patients with brucellosis, physical and/or biochemical abnormalities suggesting liver disease were found in 40 cases. A soft and tender liver enlargement was present in 65% of them, and the spleen was palpable in 52%. The most frequent biochemical abnormalities were a slight increase of serum transaminases and alkaline phosphatase. Liver biopsy showed a non-specific reactive hepatitis in 90% of patients, and minimal changes in the remaining 10%. Non-caseating granulomas were present in 28 patients, always associated with reactive hepatitis. No differences were found when comparing clinical and biochemical features in patients with and without granulomas. However, statistically significant differences were obtained when the duration of the process was related to the type of alteration found in the liver biopsy; the finding of granulomas was practically constant when the duration of the disease before liver biopsy was under 100 days, but was infrequent after this time.

    Full Text Available The most reliable diagnosis of an infectuous disease is confirmed by isolation of its pathogen. When it comes to brucellosis, it is important to know that brucella isolation is rarely successful; it is not only very complicated but is as well hazardous for laboratory workers. Due to the above mentioned reasons, it is reasonable to use serological tests for routine diagnosis of this zoonose. This paper deals with examination of bovine sera samples with the aim to detect the titer of specific antibodies against brucellosis. In order to choose and evaluate properly the best test in terms of applicability, speed of performance, and provision of correct results, five serological tests were assayed: rapid serum plate agglutination (Rose Bengal test, Brucella abortus bovis test (RB, BAB test; serum agglutination test (titration - by Wright, as micro method (mSAT; reaction of complement fixation, and also as micro method (mCF; indirect imunoenzyime test (iELISA and competitive imunoenzyme test (cELISA. This paper includes 630 samples of bovine blood sera, as well as positive and negative international antibrucella serum as the mandatory control. The presence of specific antibodies against brucella was determined in 125 samples of bovine blood sera. Based on the analysis of the results obtained, evaluation of sensitivity and specificity of these tests was conducted. iELISA and RB test proved to be the most sensitive, while the highest specificity was determined in mCF, and less specific were mSAT and iELISA. RB test had the lowest specificity.

    2011-01-01

    Brucella abortus, the causative agent of bovine brucellosis, infects wildlife, cattle, and humans worldwide, but management of the disease is often hindered by the logistics of controlling its prevalence in wildlife reservoirs. We used an individually based epidemiological model to assess the relative efficacies of three management interventions (sterilization, vaccination, and test-and-remove). The model was parameterized with demographic and epidemiological data from bison in Yellowstone National Park, USA. Sterilization and test-and-remove were most successful at reducing seroprevalence when they were targeted at young seropositive animals, which are the most likely age and sex category to be infectious. However, these approaches also required the most effort to implement. Vaccination was less effective (even with a perfect vaccine) but also required less effort to implement. For the treatment efforts we explored (50–100 individuals per year or 2.5–5% of the female population), sterilization had little impact upon the bison population growth rate when selectively applied. The population growth rate usually increased by year 25 due to the reduced number of Brucella-induced abortions. Initial declines in seroprevalence followed by rapid increases (>15% increase in 5 years) occurred in 3–13% of simulations with sterilization and test-and-remove, but not vaccination. We believe this is due to the interaction of superspreading events and the loss of herd immunity in the later stages of control efforts as disease prevalence declines. Sterilization provided a mechanism for achieving large disease reductions while simultaneously limiting population growth, which may be advantageous in some management scenarios. However, the field effort required to find the small segment of the population that is infectious rather than susceptible or recovered will likely limit the utility of this approach in many free-ranging wildlife populations. Nevertheless, we encourage

  19. Brucellosis in a high risk occupational group: sero prevalence and analysis of risk factors

    International Nuclear Information System (INIS)

    Objectives: To estimate Brucella sero positivity among slaughterhouse workers of Lahore district and to elucidate risk factors associated with sero positivity to Brucella. Method: During the year 2008, a cross-sectional study was conducted in four slaughterhouses of Lahore district. A sample of 360 workers was selected from these slaughterhouses through stratified random sampling on proportional basis. Workers were interviewed using a structured questionnaire to obtain risk factor information and their blood samples were collected to be screened for the presence of anti-Brucella IgG using Enzyme Linked Immunosorbent Assay (ELISA) technique. Data management and analysis were performed using SPSS (statistical package for social sciences) version 16. Risk factors associated with sero positivity to anti-Brucella IgG were identified by constructing a logistic regression model. Results: Of the 360 serum samples tested, 21.7% (95% CI 17.44% - 25.96%) were positive by ELISA test. The logistic regression model identified age (OR 0.96, 95% CI 0.94-0.99), assistance in parturition of animal (OR 0.47, 95% CI 0.23-0.96), consuming raw milk (OR 2.25, 95% CI 1.04-4.87) and handling sheep (OR 0.30, 95% CI 0.09- 0.92) as risk factors for Brucella sero positivity among slaughterhouse workers of Lahore district. Conclusion: To reduce the burden of brucellosis, a national brucellosis control programme should be initiated with special emphasis on the high risk population of slaughterhouse workers. (author)

    KUJTIM MERSINAJ

    2014-06-01

    Full Text Available The current brucellosis control program in small ruminants consists in two major components the first is an intervention strategy through modification of host resistance by vaccinating the entire small ruminant’s population using live attenuated Rev-1 strain of B. melitensis. The second is a post vaccination monitoring and surveillance system (MOSS to monitor the efficacy of the mass vaccination. The MOSS is based on sampling vaccinated animals between 20 to 40 days post-vaccination and testing through Rose Bengal Plate Test in order to detect antibody presence and evaluate the vaccination sero-conversion and coverage. Rose Bengal test is recommended for screening of samples to determine flock prevalence and like other serological tests it cannot discriminate between natural infection and vaccination antibodies. The methodology used in the post vaccination MOSS during the mass vaccination campaigns of 2012 and 2013 demonstrated much strength upon which future MOSS should be built. However, the current system has also shown gaps in terms of missed opportunities to analyse information generated from other sources. Trends of disease in accidental hosts like humans have not been integrated within post vaccination MOSS. Given that the infection level cannot be estimated in small ruminants, data generated by public health surveillance system can be able to give an independent overview of the impact of the vaccination campaign. This paper will address in depth this issue by showcasing the value of integrated surveillance data in monitoring the success of brucellosis control measures in small ruminants as a one health approach in practise.

    Full Text Available Abstract. The aim of this study was to compare the efficiency of different methods applied for the diagnostics of brucellosis. Huddlson and Wright reactions, RoseBengal test, ELISA-based test system (IgG determination, and a test for antigen-binding lymphocytes (ABL were used. There was shown that the specificity of tests was identical for either reactions based on detection of antibodies with commercial immune reagents and ELISA IgG. The sensitivity of ABL test is, however, superior to all the reactions based on antibody determination. The ABL test has advantages when compared with antibody detection techniques. This method permits early monitoring of brucellosis treatment/its efficiency since early terms, as well as differentiation between positive and false positive results of antibody determination in pregnant womеn.

    Full Text Available Bovine brucellosis, caused by Brucella abortus, is recognized as a chronical evolution disease with zoonotic potential what causes great loss in cattle herd due to abortion, impaired births, early animal discarding, reduction on milk and meat production as well as restriction within animal product international trade which is of high importance for national agribusiness. In bulls the disease is restricted to genital tract, characterized by seminal vesiculite and inflamation of accessory glands of the male reproductive system. Unlike cows, in bulls infection by B. abortus induces low levels or absence of serum antibodies what makes it difficult serodiagnosis by conventional methods. This paper reviewed the main aspects of brucellosis in bulls in Brazil, emphasizing diagnosis methodology and its importance to agribusiness.

    Introduction In Nigeria, there is limited information on brucellosis particularly in dogs, despite its public health implications. We undertook a sero-epidemiological survey of brucellosis in dogs to determine the prevalence of the disease and associated risk factors for its occurrence in Nigeria. Methods A cross-sectional study was conducted to screen dogs in south-western Nigeria for antibodies to Brucella sp using the rapid slide agglutination test (RSA) and Rose Bengal test (RBT), with positive samples confirmed respectively by serum agglutination test (SAT) and competitive enzyme linked immunosorbent assay (cELISA). Data were analyzed with STATA-12. Results From the 739 dog sera tested, 81 (10.96%) were positive by RSA and 94 (12.72%) by RBT; these were corroborated with SAT (4/81; 4.94%) and cELISA (1/94; 1.06%), respectively. Logistic regression identified location (OR=0.04; 95% CI: 0.02-0.09), breed (OR=1.71; 95% CI: 1.34-2.19), age (OR=0.10; 95% CI: 0.04-0.30) and management system (OR=8.51; 95% CI: 1.07-68.05) as risk factors for Brucella infection by RSA. However, location (OR=10.83; 95% CI: 5.48-21.39) and history of infertility (OR=2.62; 95% CI: 1.41-4.84) were identified as risk factors using RBT. Conclusion Given the 10.96% to 12.72% seroprevalence of brucellosis recorded in this study, we advocate control of the disease in dogs, and public health education for those at risk of infection. Again, further studies are required to elucidate the role of dogs in the epidemiology of brucellosis in Nigeria considering the conducive human-animal interface and ecological factors responsible for the transmission of the disease.

    Brucellosis is the zoonosis of world wide distribution and common cause of economic loss and ill health among animals and human populations. Patients with pyrexia of unknown origin (PUO) who were predisposed to brucellosis through rearing of animals and consumption of different animal products were tested for presence of Brucella abortus antibodies using Rose Bengal and serum agglutination antigens. Twenty six (5.2%) of the 500 patients had B. abortus antibody. The high titres of 320, 640 and 1280 obtained in the sera of patients in this study are suggestive of the endemicity of the disease in this environment. No significant difference in age and sex distribution of brucella antibody prevalence was observed. Similarly, spatial distribution of brucella antibody in different locations was not statistically significant. Although higher serological prevalence was noted in children and students than in other populations examined, the difference in prevalence between the various occupational groups was not significant. Animal handling activities including rearing are not important factors in the prevalence of brucellosis. However, among the rearers, the highest prevalence (20%) was observed among cattle handlers followed in decreasing order of prevalence by goat rearers (10%), mixed sheep and cattle rearers (9%), mixed sheep and goat rearers (8%), and 4% among each of sheep rearers and non rearers of animals. In addition, consumers of yoghurt and fresh goat milk had higher prevalence (20%) than consumers of other milk products. However, brucella antibody prevalence between consumers and non-consumers of animal products was not significantly different. The high economic loss and public health implications of brucellosis necessitates the need for effective surveillance as well as appropriate preventive and control measure among human and animal populations.

    The molecular tag vaccine against Brucella abortus and serological testing are the main methods of prevention of brucellosis used currently. They can discriminate vaccinated animals and humans from those naturally infected. In this study, we constructed a gene deletion mutant strain, B. abortus S19 virB5 with a molecular tag. Recombinant VirB5 was expressed and purified for evaluation as a diagnostic reagent for bovine brucellosis. In total, 400 sera samples were tested using a VirB5 antigen-based enzyme-linked immunosorbent assay (ELISA) and the results were compared with those of the standard tube agglutination test (SAT). This showed that the sensitivity was 88.2%, specificity was 97.8% and accuracy was 94.8%. Recombinant VirB5 could also be used to discriminate B. abortus-infected mice from mice infected with the B. abortus S19 virB5 mutant strain. It was concluded that recombinant VirB5 could be used as a potential antigen and serological marker for the diagnosis of bovine brucellosis. PMID:22662340

    Swine brucellosis caused by Brucella suis biovar 2 is an emerging disease in continental Europe. Without effective vaccines being available, the European Food Safety Authority (EFSA) recommends the full depopulation of infected herds as the only strategy to eradicate B. suis outbreaks. Using data collected from 8 herds suffering natural swine brucellosis outbreaks, we assessed the efficacy of four control strategies: (i) oxytetracycline treatment only, as a default scenario, (ii) oxytetracycline treatment combined with skin testing and removal of positive animals, (iii) oxytetracycline treatment combined with serological testing (Rose Bengal test-RBT-and indirect ELISA -iELISA-) and removal of seropositive animals and (iv) oxytetracycline treatment combined with both serological (RBT/iELISA) and skin testing and removal of positive animals. A Susceptible-Infectious-Removal model was used to estimate the reproduction ratio (R) for each strategy. According to this model, the oxytetracycline treatment alone was not effective enough to eradicate the infection. However, this antibiotic treatment combined with diagnostic testing at 4-monthly intervals plus immediate removal of positive animals showed to be effective to eradicate brucellosis independent of the diagnostic test strategy used in an acceptable time interval (1-2 years), depending on the initial number of infected animals.

    Full Text Available Abstract Background Human brucellosis has been found to be prevalent in the urban areas of Kampala, the capital city of Uganda. A cross-sectional study was designed to generate precise information on the prevalence of brucellosis in cattle and risk factors for the disease in its urban and peri-urban dairy farming systems. Results The adjusted herd prevalence of brucellosis was 6.5% (11/177, 95% CI: 3.6%-10.0% and the adjusted individual animal prevalence was 5.0% (21/423, 95% CI: 2.7% - 9.3% based on diagnosis using commercial kits of the competitive enzyme-linked immunosorbent assay (CELISA for Brucella abortus antibodies. Mean within-herd prevalence was found to be 25.9% (95% CI: 9.7% - 53.1% and brucellosis prevalence in an infected herd ranged from 9.1% to 50%. A risk factor could not be identified at the animal level but two risk factors were identified at the herd level: large herd size and history of abortion. The mean number of milking cows in a free-grazing herd (5.0 was significantly larger than a herd with a movement restricted (1.7, p Conclusions Vaccination should be targeted at commercial large-scale farms with free-grazing farming to control brucellosis in cattle in and around Kampala city.

    A cross-sectional study was conducted on the seroprevalence of horse brucellosis using the Rose Bengal Plate Test (RBPT) and Serum Agglutination Test (SAT) on the Mambilla plateau of Taraba state, Nigeria where horses are reared under a free range management system on cattle farms. The objectives of the study were to determine the prevalence of brucella antibodies in horses as well as the distribution of the infection according to sex and age. A total of 100 horses were sampled, 25 each from four locations where horses were concentrated on the plateau: Gembu, Nguroje, Dorofi, and Mayo Ndaga. Sixty-two of the horses were males, and 38 were females. Eighty of the horses were adults, while 20 were young. All horses were reared under a free range management system together with cattle. The overall seroprevalence rate was 16 (16%) according to the RBPT and 6 (6%) according to the SAT. The seroprevalence rates were 19.40% (12/62) according to the RBPT and 6.50% (4/62) according to the SAT in the males and 10.50% (4/38) according to the RBPT and 5.30% (2/38) according to the SAT in the females. The prevalence was highest in Nguroje (8/25, 32%) followed by Gembu (5/25, 20%), Dorofi (3/25, 12%) and Mayo Ndaga (0%). Adult horses showed a seroprevalence of 18.8% (n=15) according to the RBPT and 7.5% (n=1) according to the SAT. Young horses had a seroprevalence rate of only 5% (n=1) according to the RBPT and 0% (n=0) according to the SAT. There was no statistically significance association with location, sex, and age (P>0.05). From this result, it can be concluded that brucellosis in horses on the Mambilla plateau of Taraba state, Nigeria was essentially a disease of adult horses and more prevalent in male horses than female horses. Further studies need to be conducted to determine the disease status in lowland areas of the state where horses are reared on zero grazing or are tethered and also to determine the involvement of other species and humans.

  15. The role of the ELISA test in the control of bovine brucellosis in developing countries

    International Nuclear Information System (INIS)

    An FAO/IAEA enzyme immunoassay (EIA) kit for the diagnosis of bovine brucellosis was compared in Argentina with two screening tests, the rose bengal (RB) and buffered plate antigen (BPA) agglutination tests, and two confirmatory tests, the 2-mercaptoethanol (2-ME) agglutination tests and the complement fixation (CF) test. In the testing of Brucella abortus strain 19 (S19) vaccinated cattle from Brucella free dairy herds, the diagnostic specificity estimate of the EIA test was shown to be comparable to those of the RB, 2-ME and CF tests and greater than that of the BPA test. In the testing of S19 vaccinated cattle from infected herds, the sensitivity estimates of the BPA test relative to CF, 2-ME and EIA test positive reactors were comparable and high. The relative sensitivity estimates of the RB test in the same comparison were disparate and lower. The EIA test demonstrated the highest relative sensitivity estimates in a three way comparison between EIA, CF and 2-ME test reactors from these herds. Relative to BPA test reactors from the same infected herds, the sensitivity estimate of the EIA test was comparable to that of the 2-ME test and higher than that of the CF test. These results would suggest that the overall diagnostic specificity and sensitivity of the EIA test are comparable, if not superior, to those of the tests used to confirm BPA test reactor status.

    International Nuclear Information System (INIS)

    Present study was undertaken to determine the seroprevalence of brucellosis in cattle of Pabna and Mymensingh districts in Bangladesh. A total of 260 cattle sera samples were collected from Pahna and Mymensingh districts. The epidemiological data were collected by structured questionnaire. RBT and SAT were used as screening tests and further confirmed by 1-ELISA. The seroprevalence of Bruce/Ia ill cattle was estimated to be 4.23%, 3.07% and 2.31% by RBT, SAT and 1-ELISA, respectively. The comparison of the serological tests result revealed the highest prevalence in RBT than SAT and 1-EL ISA. The prevalence of Brucella was 2.5% in Pabna and 2.14% in Mymensingh. It was observed that, a higher prevalence of Bruce/la was found in female (2.67%) than in male (1.82%), natural breeding (2.67%) than artificial breeding (1.81%), in aged animals (3.33%) than young (1.25 degree percent). But these differences were not statistically significant. There exists significant difference between prevalence of Bruce/II in cattle with history of abortion than without history of abortion (P value=0.013). (author)

    Full Text Available European Union (EU Directive 97/12/EC allows the trade of cattle within the EU of animals originating from an 'officially brucellosis-free herd'. To qualify for this status, a number of different programmes must be implemented. Each EU Member Country is free to decide which procedure to use to qualify herds. The authors conducted a study to compare the merits and costs of testing programmes given in the Directive and of some alternative testing strategies. The effectiveness of testing programmes was evaluated by a Monte Carlo simulation model. Programmes listed in the Directive do not appear to have identical sensitivity and specificity. Simulations of the programmes showed that milk testing may be more effective and efficient than blood testing to identify infected herds. Results indicated that it could be advisable that legislation, rather than defining very detailed procedures both for laboratory tests and testing programmes, should establish minimal requirements in terms of efficacy of testing procedures (i.e. the probability of detecting an infected herd.

Glycoproteins generated by engineering bacterial glycosylation machineries have been proposed to be a viable alternative to traditional conjugation methods. Results In this work we expressed the C. jejuni oligosaccharyltansferase (OTase PglB, responsible for N-linked protein glycosylation together with a suitable acceptor protein (AcrA in Yersinia enterocolitica O9 cells. MS analysis of the acceptor protein demonstrated the transfer of a polymer of N-formylperosamine to AcrA in vivo. Because Y. enterocolitica O9 and Brucella abortus share an identical O polysaccharide structure, we explored the application of the resulting glycoprotein in vaccinology and diagnostics of brucellosis, one of the most common zoonotic diseases with over half a million new cases annually. Injection of the glycoprotein into mice generated an IgG response that recognized the O antigen of Brucella, although this response was not protective against a challenge with a virulent B. abortus strain. The recombinant glycoprotein coated onto magnetic beads was efficient in differentiating between naïve and infected bovine sera. Conclusion Bacterial engineered glycoproteins show promising applications for the development on an array of diagnostics and immunoprotective opportunities in the future.

    Full Text Available A seroprevalence study was carried out among trade cattle slaughtered at Bodija Municipal Abattoir, Ibadan (southwestern Nigeria over a period of 3 consecutive years from 2004 to 2006 with a view to determining the breed, sex and age distribution in the seropositivity of bovine brucellosis. In total, 1642 animals were examined for antibodies to Brucella abortus using the Rose Bengal test. Seroprevalences of 6.00 %, 6.17 % and 5.31 % were obtained in the years 2004, 2005 and 2006, respectively but a decrease in 2006 shows no significant difference (P>0.05. The role of the breed (P>0.05, sex (P>0.05 and age (P>0.05 in the occurrence of the infection was not statistically significant at 5 %, although higher rates were obtained for females and older animals. The trend in the disease over the 3-year period showed that it is endemic in trade cattle slaughtered in Ibadan and the public health implications of this are discussed.

    Full Text Available Brucellosis is a highly infectious zoonotic disease and an economically important infection of humans and livestock with a worldwide distribution. The main mode of transmission of this disease to humans is through the consumption of infected milk, milk products, and uncooked or raw meat. The present study was designed to prepare few native antigens, that is, sonicated antigen (SA, cell envelope (CE antigen, and freeze and thaw (FT antigen from Brucella abortus S99 culture and to test them in a highly sensitive and specific indirect enzyme-linked immunosorbent assay (I-ELISA in both a microtiter plate and a dot-blot format for the development of field-based diagnosis. All 50 suspected bovine samples were tested by plate as well as in dot ELISA formats for all the three antigens prepared. The CE antigen was found to be more suitable as it had the maximum agreement with the Rose Bengal plate agglutination test results followed by the SA and the least agreement was found with that of the FT antigen. This detection system in microtiter plates and a dot-blot format will be useful for the rapid screening of samples for the disease surveillance and routine diagnosis.

    This paper reports a first-time study performed in El Salvador on the presence or absence of antibodies to three important animal diseases in small ruminants. The work was conducted in the west and central departments of the country, selecting 42 and 43 cantons with an existing sheep and goat population, respectively. Serum samples were collected from 396 sheep and 335 goats and tested for seropositivity to Brucella (B.) spp. The specimens from goats were also tested for antibodies to caprine arthritis-encephalitis (CAE) virus. Four (1 %) sheep and none of the goats were seropositive by Rose Bengal test. All animals were negative by indirect ELISA (iELISA) for B. abortus. All animals were negative by iELISA for CAE. A total of 383 sheep and 330 goats underwent the single intradermal cervical tuberculin (SICT) test for tuberculosis. Seventy (18 %) sheep and 43 (13 %) goats reacted to the SICT test. Those reactors were subjected to the single intradermal comparative cervical tuberculin (SICCT) test, and one (0.3 %) goat was deemed to be a positive reactor. No mycobacteria were diagnosed in concluding analyses, and further studies are considered necessary to determine the prevalence of the investigated diseases. Additionally, it is recommended that small ruminants should be included in the national eradication program on bovine brucellosis and tuberculosis to prevent potential reservoirs. PMID:26992736

    Full Text Available Aim: A study on surveillance of bovine brucellosis in dairy herds of peri-urban areas under intensive system of production was carried out by milk-ELISA. Various risk factors were identified having significant association with occurrence of bovine brucellosis in dairy herds of peri-urban areas. Materials and Methods: Five randomly selected peri-uban areas of six cities of Gujarat were included in the present study. Five randomly selected dairy herds under intensive system of production from each selected peri-urban area were included for further investigation. In total, 199 bulk and 582 individual milk samples were screened by milk-ELISA. Forty three different risk factors were identified and grouped into four major categories as general characteristics of farms, introduction of infection to farms, management systems of farms and exposure of disease. Further, their distribution and association with prevalence of bovine brucellosis was studied. Results: The overall herd and animal prevalence in peri-urban areas was 33.70 and 11.90%, respectively. Out of 11 risk factors on general characteristics of dairy farms, only five (herd size, type of animals, type of breed, age of owner and knowledge gained by owners showed significant (p<0.05 association with occurrence of bovine brucellosis. None of risk factors on introduction of infection to farms (n=6 and management systems of farms (n=11 was found significantly associated with occurrence of brucellosis. Among risk factors on exposure of disease (n=15, history of abortion, retention of placenta, still birth and metritis/endometritis showed significant (p<0.05 association with prevalence of bovine brucellosis. Conclusion: It was concluded that prevalence of bovine brucellosis in dairy herds under intensive system of production in peri-urban areas of Gujarat was comparatively higher than reported overall prevalence of brucellosis.

    Limited data are available on the risk factors responsible for the occurrence of brucellosis amongst different cattle production systems in Nigeria despite its significant impact on livestock production. Consequently, a cross-sectional study was conducted to determine the prevalence of bovine brucellosis in three cattle production systems in Yewa Division of Ogun State, south-western Nigeria. A total of 279 blood samples (sedentary = 88; transhumance = 64; trade = 127) were examined for antibodies to Brucella sp. using the Rose Bengal test (RBT) and competitive enzyme-linked immunosorbent assay (cELISA). Overall, 24 (8.6%) and 16 (5.7%) of the animals tested seropositive for Brucella using RBT and cELISA, respectively. The herd seroprevalences based on RBT and cELISA were 31.6% and 15.8%, respectively. The results using cELISA reveal higher seroprevalence in the trade cattle (7.9%; confidence intervals [CI] = 3.2% - 12.6%) and those in a sedentary system (5.7%; CI = 0.9% - 10.5%) than in cattle kept under a transhumant management system (1.6%; CI = 1.5% - 4.7%). Age (> 3 years; p = 0.043) and breed (Djali; p = 0.038) were statistically significant for seropositivity to brucellosis based on cELISA, but sex (female, p = 0.234), production system (trade and sedentary; p = 0.208) or herd size (> 120; p = 0.359) was not. Since breeding stock is mostly sourced from trade and sedentary cattle, it is important that routine serological screening should be conducted before introducing any animal into an existing herd.

    Brucellosis is one of the most prevalent zoonotic diseases of worldwide distribution caused by the infection of genus Brucella. Live attenuated vaccines such as B. abortus S19, B. abortus RB51 and B. melitensis Rev1 are found most effective against brucellosis infection in animals, contriving a number of serious side effects and having chances to revert back into their active pathogenic form. In order to engineer a safe and effective vaccine candidate to be used in both animals and human, a recombinant subunit vaccine molecule comprising the truncated region of glucokinase (r-glk) gene from B. abortus S19 was cloned and expressed in Escherichia coli BL21DE3 host. Female BALB/c mice immunized with purified recombinant protein developed specific antibody titer of 1:64,000. The predominant IgG2a and IgG2b isotypes signified development of Th1 directed immune responses. In vitro cell cytotoxicity assay using anti-r-glk antibodies incubated with HeLa cells showed 81.20% and 78.5% cell viability against lethal challenge of B. abortus 544 and B. melitensis 16M, respectively. The lymphocyte proliferative assay indicated a higher splenic lymphocyte responses at 25μg/ml concentration of protein which implies the elevated development of memory immune responses. In contrast to control, the immunized group of mice intra-peritoneal (I.P.) challenged with B. abortus 544 were significantly protected with no signs of necrosis and vacuolization in their liver and spleen tissue. The elevated B-cell response associated with Th1 adopted immunity, significant in vitro cell viability as well as protection afforded in experimental animals after challenge, supplemented with histopathological analysis are suggestive of r-glk protein as a prospective candidate vaccine molecule against brucellosis.

  9. Comparison of a flow assay for brucellosis antibodies with the reference cELISA test in West African Bos indicus.

    Full Text Available Brucellosis is considered by the Food and Agricultural Organisation and the World Health Organisation as one of the most widespread zoonoses in the world. It is a major veterinary public health challenge as animals are almost exclusively the source of infection for people. It is often undiagnosed in both human patients and the animal sources and it is widely acknowledged that the epidemiology of brucellosis in humans and animals is poorly understood, particularly in sub-Saharan Africa. It is therefore important to develop better diagnostic tools in order to improve our understanding of the epidemiology and also for use in the field for disease control and eradication. As with any new diagnostic test, it is essential that it is validated in as many populations as possible in order to characterise its performance and improve the interpretation of its results. This paper describes a comparison between a new lateral flow assasy (LFA for bovine brucellosis and the widely used cELISA in a no gold standard analysis to estimate test performance in this West African cattle population. A Bayesian formulation of the Hui-Walter latent class model incorporated previous studies' data on sensitivity and specificity of the cELISA. The results indicate that the new LFA is very sensitive (approximately 87% and highly specific (approximately 97%. The analysis also suggests that the current cut-off of the cELSIA may not be optimal for this cattle population but alternative cut-offs did not significantly change the estimates of the LFA. This study demonstrates the potential usefulness of this simple to use test in field based surveillance and control which could be easily adopted for use in developing countries with only basic laboratory facilities.

    Brucellosis is one of the important zoonotic diseases among livestock. This study was carried out to estimate the prevalence of brucellosis and isolate Brucella spp. in sheep in Kassala State in the east of Sudan. Two thousand and five serum samples were randomly collected from nine different localities. All serum samples were examined by the Rose Bengal plate test (RBPT) and the modified RBPT (mRBPT). Forty-three (2.15%, 95% confidence interval [CI]: 1.6,3.0) and 68 (3.4%, 95% CI: 2.6, 4.2) samples were positive with the RBPT and the mRBPT, respectively. According to a known diagnostic sensitivity of 86.6% and a known diagnostic specificity of 97.6% for the mRBPT, the true prevalence was estimated to be 1.2% (95% CI: 0.3, 2.2). Different tissue samples were collected from 41 mRBPT seropositive animals. Brucella abortus biovar 6 was isolated from a pyometra of a seropositive ewe. It is important to note that B. abortus biovar 6 cannot be differentiated from Brucella melitensis biovar 2 by routine bacteriology. Only phage typing performed in reference laboratories will allow accurate identification of the strain. The fact that B. abortus biovar 6 does not require CO2 for growth, combined with the fact that it has been isolated from a small ruminant in this study, could easily have led to misidentification (as B. melitensis biovar 2), to wrong epidemiological inferences and to the implementation of inappropriate control measures. The results presented here suggest that sheep are spillover hosts, as previously described for camels, and that the actual reservoir of B. abortus biovar 6 is cattle in Kassala State, Eastern Sudan. This study highlights the importance of isolating and identifying Brucella spp. in different livestock species in order to accurately decipher brucellosis epidemiology in sub-Saharan Africa.

  13. Brucellosis vaccines: assessment of Brucella melitensis lipopolysaccharide rough mutants defective in core and O-polysaccharide synthesis and export.

    Directory of Open Access Journals (Sweden)

    David González

    Full Text Available BACKGROUND: The brucellae are facultative intracellular bacteria that cause brucellosis, one of the major neglected zoonoses. In endemic areas, vaccination is the only effective way to control this disease. Brucella melitensis Rev 1 is a vaccine effective against the brucellosis of sheep and goat caused by B. melitensis, the commonest source of human infection. However, Rev 1 carries a smooth lipopolysaccharide with an O-polysaccharide that elicits antibodies interfering in serodiagnosis, a major problem in eradication campaigns. Because of this, rough Brucella mutants lacking the O-polysaccharide have been proposed as vaccines. METHODOLOGY/PRINCIPAL FINDINGS: To examine the possibilities of rough vaccines, we screened B. melitensis for lipopolysaccharide genes and obtained mutants representing all main rough phenotypes with regard to core oligosaccharide and O-polysaccharide synthesis and export. Using the mouse model, mutants were classified into four attenuation patterns according to their multiplication and persistence in spleens at different doses. In macrophages, mutants belonging to three of these attenuation patterns reached the Brucella characteristic intracellular niche and multiplied intracellularly, suggesting that they could be suitable vaccine candidates. Virulence patterns, intracellular behavior and lipopolysaccharide defects roughly correlated with the degree of protection afforded by the mutants upon intraperitoneal vaccination of mice. However, when vaccination was applied by the subcutaneous route, only two mutants matched the protection obtained with Rev 1 albeit at doses one thousand fold higher than this reference vaccine. These mutants, which were blocked in O-polysaccharide export and accumulated internal O-polysaccharides, stimulated weak anti-smooth lipopolysaccharide antibodies. CONCLUSIONS/SIGNIFICANCE: The results demonstrate that no rough mutant is equal to Rev 1 in laboratory models and question the notion that

    Brucellosis is a zoonotic infectious disease that can be transmitted to humans through infected milk and dairy products. There are limited cases with Brucella infection acquired via breastfeeding in infants in the literature. Also, Coombs-positive autoimmune hemolytic anemia as a result of the disease is comparatively rare when considering the other frequent hematologic complications. We report a mother who acquired the infection as a result of consuming infected milk and dairy products after delivery and of her 5-month-old baby, who had acquired the disease via breastfeeding and presented with Coombs-positive autoimmune hemolytic anemia.

    Molecular approaches have been investigated to overcome difficulties in identification and differentiation of Brucella spp. using conventional phenotypic methods. In this study, high-resolution melt (HRM) analysis was used for rapid identification and differentiation of members of Brucella genus. A total of 41 Brucella spp. isolates from human brucellosis were subjected to HRM analysis using 4 sets of primers, which identified 40 isolates as Brucella melitensis and 1 as Brucella canis. The technique utilized low DNA concentration and was highly reproducible. The assay is shown to be a useful diagnostic tool, which can rapidly differentiate Brucella up to species level.

    Full Text Available I metodi ufficiali previsti dal Piano nazionale di eradicazione della brucellosi bovina ed ovi-caprina sono la sieroagglutinazione rapida (SAR con l’antigene acidificato al Rosa Bengala e la fissazione del complemento (FDC. Nella attuale fase del piano di eradicazione non è infrequente imbattersi in risultati di difficile interpretazione ottenuti con i test ufficiali, pertanto è necessario poter disporre di test aggiuntivi che presentino livelli di specificità e di sensibilità più elevati. A questo scopo sono stati validati due metodi ELISA, indiretto (i-ELISA CL e competitivo (c-ELISA CL, mediante l’utilizzo di un substrato chemiluminescente per la determinazione di anticorpi anti-Brucella in siero bovino ed ovino. I metodi si basano sulla rivelazione degli anticorpi anti-Brucella, contenuti nel siero, mediante la catalisi di un substrato enzimatico chemiluminescente (sistema luminolo/H2O2/ enhancer, da parte della perossidasi coniugata ad anticorpi secondari anti-IgG, nella i-ELISA CL, o al monoclonale anti-LPS, nella c-ELISA CL. Sulla base dei risultati ottenuti, per l'i-ELISA CL è stato stabilito un valore di cut-off, espresso come percentuale di positività (PP, del 60% per i sieri bovini e del 37,5% per quelli ovini; con questo valore di cut-off si ottiene una sensibilità ed una specificità del test del 100% per i sieri bovini, e una sensibilità del 100% e una specificità del 99,8% per quelli ovini. Per la c-ELISA CL è stato scelto un cut-off, espresso come percentuale di inibizione (PI, del 30% per i sieri bovini e del 40% per quelli ovini, che assicura valori di sensibilità e specificità del 100% in entrambi i casi.

Following confirmation of bovine T lymphocyte cell lines derived from Brucella abortus Strain 19 vaccinated steers as antigen-specific in proliferation studies using various antigens, we adapted an apoptosis assay for evaluation of cytotoxicity by these bovine T cells against autologous monocyte-derived macrophages (MDM Phi) as target cells. Various B. abortus antigen preparations were tested including whole gamma-irradiated B. abortus bacteria (gamma BA), a soluble cytosolic protein fraction and a membrane-associated protein fraction. Both polyclonal and cloned T lymphocyte cell lines exhibited cytotoxicity against MDM Phi targets in an antigen-specific fashion. Polyclonal and cloned T lymphocyte cell lines demonstrated cytotoxic responses to varying degrees against B. abortus antigens regardless of whether the antigen used was whole nonviable bacteria, a soluble protein extract or a membrane-associated fraction of extracted bacteria. To further develop correlation of these responses to an in vivo host defense mechanism, cytotoxicity was evaluated using target cells that had been infected with live B. abortus S19 or B. abortus Strain 2308. Cytotoxic responses were also demonstrated consistently against infected targets with either strain of B. abortus although in most cases, cytotoxicity was higher against target cells sensitized with gamma BA compared to those infected with live bacteria. Cloned T lymphocyte cell lines were all CD4+, CD8(-) cells indicating that the observed cytotoxic responses were most likely due to an inflammatory Th1 response and may represent an important host defense mechanism induced by vaccination with live attenuated strains of B. abortus in cattle.

    Epidemiological data are often fragmented, partial, and/or ambiguous and unable to yield the desired level of understanding of infectious disease dynamics to adequately inform control measures. Here, we show how the information contained in widely available serology data can be enhanced by integration with less common type-specific data, to improve the understanding of the transmission dynamics of complex multi-species pathogens and host communities. Using brucellosis in northern Tanzania as a case study, we developed a latent process model based on serology data obtained from the field, to reconstruct Brucella transmission dynamics. We were able to identify sheep and goats as a more likely source of human and animal infection than cattle; however, the highly cross-reactive nature of Brucella spp. meant that it was not possible to determine which Brucella species (B. abortus or B. melitensis) is responsible for human infection. We extended our model to integrate simulated serology and typing data, and show that although serology alone can identify the host source of human infection under certain restrictive conditions, the integration of even small amounts (5%) of typing data can improve understanding of complex epidemiological dynamics. We show that data integration will often be essential when more than one pathogen is present and when the distinction between exposed and infectious individuals is not clear from serology data. With increasing epidemiological complexity, serology data become less informative. However, we show how this weakness can be mitigated by integrating such data with typing data, thereby enhancing the inference from these data and improving understanding of the underlying dynamics.

  9. Use of enzyme linked immunosorbent assay (ELISA) for the diagnosis of brucellosis in cattle in Yucatan, Mexico

    International Nuclear Information System (INIS)

    Sera (247) from non-vaccinated brucellosis negative herds, 328 negative sera from Brucella abortus strain 19 vaccinated herds (brucellosis free), and 95 sera positive to the Rose Bengal test (RBT) and Complement Fixation test (CFT) from Brucella abortus-infected herds, were used to determine the relative sensitivity and specificity of a FAO/IAEA I-ELISA kit and the Rivanol Agglutination Test (RAT), using the CFT as a 'gold standard'. A threshold value for the I-ELISA was determined to be 37 PP using the mean plus 3 standard deviations of the negative sera from vaccinated animals. The I-ELISA showed a high relative sensitivity (100%) and a good relative specificity (92.5%), using the threshold determined for local conditions. The RAT gave a lower sensitivity value than the CFT (97.8%) and good specificity (99.3%). The I-ELISA could be used as a screening test under Yucatan conditions or as a confirmatory test in places where vaccination is not carried out. The RAT lacks sensitivity and is therefore not recommended for use in final stages of eradication programs but could be used in control programmes or early stages of eradication campaigns as a confirmatory test.

    A proof of concept investigation was performed to demonstrate that two independent infectious diseases of cattle result in different patterns of volatile organic compounds (VOC) in the headspace of serum samples detectable using an electronic nose (e-nose). A total of 117 sera from cattle naturally infected with Mycobacterium avium subsp. paratuberculosis (paraTB, n = 43) or Brucella sp. (n = 26) and sera from corresponding control animals (n = 48) were randomly and analysed blind to infection status using a ST214 e-nose (Scensive Ltd, Leeds, UK). Samples were collected under non-standardised conditions on different farms from the UK (brucellosis) and Germany (paraTB). The e-nose could differentiate the sera from brucellosis infected, paraTB infected and healthy animals at the population level, but the technology used was not suitable for determination of the disease status of individual animals. Nevertheless, the data indicate that there are differences in the sensor responses depending on the disease status, and therefore, it shows the potential of VOC analysis from serum headspace samples for disease detection.

    A cross sectional study was conducted to investigate seroprevalence and associated risk factors of bovine brucellosis in Fulani nomadic herds in the 3 agro-ecological zones of Niger State, North-central Nigeria between January and August 2013. A total of 672 cattle in 113 herds were screened for Brucella antibodies using Rose Bengal Plate Test (RBPT) and confirmed by Lateral flow Assay (LFA). Data on herd characteristics and zoonotic factors were collected using structured questionnaire administered on Fulani herd owners. Factors associated with Brucella infection were tested using Chi-square test and multivariable logistic model. The overall cattle-level seroprevalence was 1.9% (95% CI: 1.1-3.2) with highest in agro-zone C (3.2%). Herd-level seroprevalence was 9.7% (95% CI: 5.23-16.29) and highest in agro-zone C (13.5%). Sex and agro-ecological zones were significantly (Ppractices were significantly associated with brucellosis occurrence. Inhalation of droplets from milk of infected cows, and drinking raw milk were less likely [OR 0.27; 95% CI: 0.09-0.82 and OR 0.27; 95% CI: 0.08-0.99, respectively] not to predisposed to brucellosis in humans. Eating infected raw meat, and contact with infected placenta were more likely [OR 7.49; 95% CI: 2.06-28.32 and OR 5.74; 95% CI: 1.78-18.47, respectively] to be risks for the disease in humans. These results highlighted the important risk factors for bovine brucellosis in Fulani herds. Thus, brucellosis control programs which take these factors into consideration will be beneficial.

    Full Text Available Brucellosis is a zoonotic disease of veterinary, public health, and economic significance in most developing countries, yet there are few studies that show integrated human and veterinary health care intervention focusing on integration at both activity and actors levels. The aim of our study, therefore, was to explore community perceptions on integration of animal vaccination and health education by veterinary and public health workers in the management of brucellosis in Uganda.This study used a qualitative design where six Focus Group Discussions (FGDs that were homogenous in nature were conducted, two from each sub-county, one with the local leaders, and another with pastoralists and farmers. Five Key Informant Interviews (KIIs with two public health workers and three veterinary extension workers from three sub-counties in Kiruhura district, Uganda were conducted. All FGDs were conducted in the local language and tape recorded with consent from the participants. KIIs were in English and later transcribed and analyzed using latent content data analysis method.All the groups mentioned that they lacked awareness on brucellosis commonly known as Brucella and its vaccination in animals. Respondents perceived improvement in human resources in terms of training and recruiting more health personnel, facilitation of the necessary activities such as sensitization of the communities about brucellosis, and provision of vaccines and diagnostic tests as very important in the integration process in the communities. The FGD participants also believed that community participation was crucial for sustainability and ownership of the integration process.The respondents reported limited knowledge of brucellosis and its vaccination in animals. The community members believed that mass animal vaccination in combination with health education about the disease is important and possible if it involves government and all other stakeholders such as wildlife authorities

Methods Retrospective analysis on 12 cases of Brucellosis from January 2010 to December 2011 were performed. Results Brucellosis could take place anytime during the whole year, especially in spring, summer and autumn. The transmission route was complicated. It often happened in special population. It was easy to be misdiagnosed in the early course of disease because its clinical symptoms were not typical. Rifampin and doxycycline were used together to treat Brucellosis, and quin-olone was added when the disease aggravated. Conclusion Better understanding of the clinical characteristics of Brucellosis can increase the diagnosis rate and optimize the treatment.

    Background The culture has always been the gold standard test for diagnosis of human brucellosis but the conventional Brucella diagnostic tests viz. serology and culture are often beset with poor specificity & sensitivity respectively. The culture positivity rates for Brucella vary from 92% for bone marrow to 10% for non-blood samples and also dependent on the type of sample. The primary immune-determinant for Brucella species is the cell wall surface lipopolysaccharide, which is antigenically similar to other gram-negative rods. Hence, Brucella serological tests cross react with Escherichia coli 0116 and 0157, Salmonella urbana, Yersinia enterocolitica 0:9, Vibrio cholerae, Xanthomonas maltophilia and Afipia clevellandensis infections, which are common in developing countries also having higher incidence of brucellosis. Aim The aim of the study was evaluation of conventional serological techniques and PCR for diagnosis of human brucellosis in and around north Karnataka which is endemic for brucellosis and patients often present with elevated base line antibody titers and confounding clinical manifestations. Materials and Methods Blood/serum samples of 400 patients suffering from acute undifferentiated fever (AUF) were subjected to culture, Brucella slide agglutination test (SAT), standard tube agglutination test (STAT coupled with 2 ME) and PCR. Results Of the 400 AUF patients, anti-Brucella antibodies were detected by SAT and STAT in serum of 35 and 34 patients respectively. IS711 gene for Brucella was identified in 32 patients by PCR. Twenty samples yielded Brucella in culture on biphasic medium with average incubation period of 9 days. All patients having titer of ≥ 160IU / ml in STAT were found positive by PCR also. Conclusion Brucella STAT corroborated well with PCR results in all those cases where antibodies were present at least one dilution above cut-off value of 80 IU/ml. We probably need to raise cut-off titers to ≥160 IU/ml because of endemic region

    A competitive ELISA (Brucella-Ab c-ELISA) was standardized and validated for the detection of Brucella antibodies in cattle, sheep and goat sera using a monoclonal antibody (MAb 4B5A) produced against Brucella melitensis biotype 2. The specificity and sensitivity of the assay were 100% to a 67.5% cut-off point (B/Bo%). When compared with an indirect ELISA, the Brucella-Ab c-ELISA did not demonstrate cross-reactions when testing positive sera for antibodies to some Enterobacteriaceae. A comparison was made between the Brucella-Ab c-ELISA and the complement fixation and Rose Bengal tests. Results demonstrated that the Brucella-Ab c-ELISA is a valuable tool for the serological diagnosis of bovine and ovine/caprine brucellosis. PMID:17123429

    Bovine brucellosis is one of the most important zoonotie diseases worldwide, and is widely spread in developing countries. The disease, which results in serious economic losses due to late term abortion, stillborn and weakly calves, is caused by Gram negative coccobacilli bacteria of the genus Brucella. Lesions consist of necrotic placentitis and interstitial mastitis in pregnant cows, and fibrinous pleurifis with interstitial pneumonia in aborted fetuses and newborn calves. The pathogenesis of Brucella abortus and the ability of the pathogen to invade phagocytic and nonphagocytic host cells, resist the acidified intraphagosomal environment, and inhibit phagosome - lysosome fusion were expounded.Significant aspects of innate and adaptive immunity against brucellosis were also discussed.%牛布鲁氏菌病是一种非常重要的世界流行的动物传染病.在发展中国家流行范围广,经济损失严重.该病的病原是一种革兰氏阴性球杆菌,能够引起怀孕母牛胎盘坏死及间质性乳腺炎,新生小牛多患有纤维素性肺炎.就流产布鲁氏菌的致病性、时吞噬细胞和非吞噬细胞的侵袭力、在胞内的生存机制及阻碍吞噬细小体-溶酶体的粘附进行综述,尤其对获得性免疫反应如何抵抗布鲁氏菌感染作了重要的阐述.

  4. The use of gene-based technology to determine the prevalence of dairy and beef cattle with a natural resistance to bovine brucellosis in South Africa

    International Nuclear Information System (INIS)

    Full text: Bovine brucellosis is a highly contagious disease caused by Brucella abortus. The principal manifestations of brucellosis are reproductive failure including mid- to late-term abortions or birth of unthrifty calves, infertility in cows and orchitis and epididymitis with frequent sterility in the male. The disease has a high prevalence in southern Africa, especially in intensively farmed areas, and is the most important bacterial cause of abortion on the subcontinent. Although cattle diseases can be partially controlled by the use of antimicrobials, pesticides, vaccines, isolation-and-quarantine, and test-and-slaughter policies, sustained losses due to infectious diseases continue to impede the livestock industry. For the past decade, the use of antimicrobials has been increasingly criticized because of the development of antimicrobial resistant pathogens and the dangers of residues in animal products used as food for human consumption. A balanced strategy in which drug use is minimized and the emphasis is placed on breeding disease resistant livestock must be considered. An area of recurrent interest in this regard is to increase the overall level of resistance in a herd by using selective breeding programs based on gene bases technologies. 'Natural disease resistance' refers to the inherent capacity of an animal to resist disease when exposed to pathogens, without prior exposure or immunization, of which the major component is heritable and, therefore, stably passed from parent to offspring. Because antibiotics cannot effectively cure bovine brucellosis, only three approaches are currently available to control the disease viz. a combination of vaccination, hygiene, and/or 'test and slaughter'. It was therefore decided to concentrate on the exploitation of natural resistance as a fourth important tool to control and eradicate the disease in South Africa. It has been shown that natural resistance to brucellosis can be dramatically increased by selection

    The rapid, indirect enzyme-labeled antibody (ELA) microplate test has been developed as a diagnostic and surveillance tool to aid in the control of animal disease. Data are presented, which illustrate the application of the test to viral (hog cholera), parasitic (trichinosis), and bacterial (brucellosis) diseases of animals. A greater than 95 percent correlation was observed between the hog cholera ELA test and the hog cholera serum neutralization test performed on over 2000 mixed hog cholera positive and negative field samples obtained during the 1976 New Jersey epizootic. Of 56 swine naturally infected with Trichinella spiralis at a level considered dangerous to man, all were ELA positive, while only one of 360 T. spiralis negative packing house sera was ELA positive. Preliminary experiments with bovine brucellosis (Brucella abortus) indicate that the ELA test is more sensitive than other test methods currently in use. ELA procedures should soon become tests of choice for the detection of antibodies to animal disease agents.

    Bovine brucellosis is an economically important disease which seriously affects dairy farming by causing colossal losses. It can be controlled by practicing vaccination of animals with Brucella abortus S19 vaccine (S19 vaccine). In the present study, adult bovines were vaccinated on seven dairy farms with a reduced dose of S19 vaccine to control brucellosis. Serological screening of adult animals (N = 1,082) by Rose Bengal test (RBT) and ELISA prior to vaccination revealed the presence and absence of brucellosis on five and two farms, respectively. The positive animals (N = 171) were segregated and those which tested negative (N = 911) were vaccinated by conjunctival route with a booster after 4 months. The conjunctival vaccination induced weak antibody response in animals, which vanished within a period of 9 to 12 weeks. Abortion in 12 animals at various stages of pregnancy and post-vaccination was recorded, but none was attributed to S19 vaccine. However, virulent B. abortus was incriminated in six heifers, and the cause of abortion could not be established in six animals. The six aborted heifers perhaps acquired infection through in utero transmission or from the environment which remained undetected until abortion. These findings suggested that vaccination of adult animals with a reduced dose of S19 vaccine by conjunctival route did not produce adverse effects like abortion in pregnant animals and persistent vaccinal antibody titers, which are the major disadvantages of subcutaneous vaccination of adult animals.

    Full Text Available Background and Objectives: Brucellosis is among the most common zoonotic diseases. Educational programs can be effective in the prevention of this disease in humans. The present study was conducted to assess the effectiveness of an educational intervention based on the Health Belief Model (HBM in the empowerment of stockbreeders against high risk behaviors associated with brucellosis in Charuymaq county, East Azerbaijan. Materials and Methods: The present quasi-experimental study was conducted in 2014 in Charuymaq county. A total of 200 people selected through stratified random sampling participated in the study. Data were collected using a researcher-designed questionnaire including items on participants' demographic information, knowledge and the HBM constructs. Training sessions were then designed and held for the intervention group. Three months after the intervention was held, data were collected from both groups and then analyzed using descriptive statistics including the Mann-Whitney U test and the Wilcoxon test. Results: The mean scores obtained for knowledge, HBM constructs (perceived susceptibility, severity, barriers and benefits and self-efficacy and brucellosis preventive behaviors showed no significant differences between the two groups before the intervention however, after the educational intervention, significant differences were observed between the mean scores obtained by the intervention group and the control group (P<0.05. Conclusion: The cooperation of charismatic individuals with intervention programs and the use of education theories can be more effective in modifying high-risk behaviors these programs should therefore be widely implemented across the country.

Methods The epidemic data of brucellosis in Baoding from 2007 to 2012 were analyzed epidemiologically, according to Disease Surveillance Information Reporting System. Results Human brucellosis was distributed in 24 counties out of 25 of the whole city. And the incidence was 1.36 to 2.38 hundred thousandth. From 3-month-olds to 83-year-olds, the patients were mostly the young and adults. The ratio of male and female patients was 2.59: 1. Brucellosis cases, which occurred more frequently from April to August, were apparently seasonal. Occupationally, stock breeding farm workers, butchers and fur processors were at high risk of infection. Conclusion The incidence of human brucellosis in the city of Baoding has been high since 2007. Public awareness had improved, since surveillance and health intervention has been continuously carried out by health department. Meanwhile, the separation of knowledge and behavior still exists.

    Understanding the seasonal timing of disease transmission can lead to more effective control strategies, but the seasonality of transmission is often unknown for pathogens transmitted directly. We inserted vaginal implant transmitters (VITs) in 575 elk (Cervus elaphus canadensis) from 2006 to 2014 to assess when reproductive failures (i.e., abortions or still births) occur, which is the primary transmission route of Brucella abortus, the causative agent of brucellosis in the Greater Yellowstone Ecosystem. Using a survival analysis framework, we developed a Bayesian hierarchical model that simultaneously estimated the total baseline hazard of a reproductive event as well as its 2 mutually exclusive parts (abortions or live births). Approximately, 16% (95% CI = 0.10, 0.23) of the pregnant seropositive elk had reproductive failures, whereas 2% (95% CI = 0.01, 0.04) of the seronegative elk had probable abortions. Reproductive failures could have occurred as early as 13 February and as late as 10 July, peaking from March through May. Model results suggest that less than 5% of likely abortions occurred after 6 June each year and abortions were approximately 5 times more likely in March, April, or May compared to February or June. In western Wyoming, supplemental feeding of elk begins in December and ends during the peak of elk abortions and brucellosis transmission (i.e., Mar and Apr). Years with more snow may enhance elk-to-elk transmission on supplemental feeding areas because elk are artificially aggregated for the majority of the transmission season. Elk-to-cattle transmission will depend on the transmission period relative to the end of the supplemental feeding season, elk seroprevalence, population size, and the amount of commingling. Our statistical approach allowed us to estimate the probability density function of different event types over time, which may be applicable to other cause-specific survival analyses. It is often challenging to assess the

    International Nuclear Information System (INIS)

    The results of an indirect ELISA (I-ELISA) and a competitive ELISA (C-ELISA) for detection of antibody to Brucella abortus in cattle were compared with those of conventional serological tests. The sensitivity of I-Elisa using 230 sera from infected animals was 98.6% and the specificity in 720 sera from brucellosis-free animals was 98.2%. The C-ELISA when tested in 94 positive sera and 91 negative sera was 100% sensitive and specific. The relative sensitivity and specificity of I-ELISA compared to C-ELISA in 582 sera from groups of animals vaccinated with S19 by different routes and doses was respectively 64% and 100%. When comparing five serological tests on sera from vaccinated animals, the specificity was 94% for C-ELISA, 93% for 2-mercaptoethanol (2ME), 88% for Rose Bengal Plate test (RBPT), 84% for Slow Tube Agglutination test (SAT) and 34% for I-ELISA. It can be concluded from this study that the RBPT gave less false positive results than the I-ELISA in vaccinated animals and the C-ELISA is a good confirmatory test with the advantage of distinguishing the antibody response due to vaccination from that resulting from infection with Brucella abortus.

    An adult male muskox ( Ovibos moschatus ), harvested on 26 August 2014 on Victoria Island, Nunavut, in the Canadian Arctic, had proliferative dermatitis on the muzzle and fetlocks suggestive of contagious ecthyma or orf (Parapoxvirus). Histopathologic features of the lesions were consistent with this diagnosis. Orf virus DNA, phylogenetically similar to an isolate from a captive muskox of the Minnesota Zoo, US, was detected in the lesions by PCR using Parapoxvirus primers. Additionally, there was a metaphyseal abscess with a cortical fistula in the right metacarpus from which Brucella suis biovar 4 was isolated and identification supported by PCR. Brucella spp. antibodies were detected in serum. Finally, 212 nodules were dissected from the lungs. Fecal analysis and lung examination demonstrated co-infection with the lungworms Umingmakstrongylus pallikuukensis and Varestrongylus eleguneniensis. The zoonotic potential of orf and rangiferine brucellosis adds an important public health dimension to this case, particularly given that muskoxen are a valuable source of food for Arctic residents. Careful examination of these pathogens at a population level is needed as they may contribute to muskox population decline and potentially constitute a driver of food insecurity for local communities. This case underscores the importance of wildlife health surveillance as a management tool to conserve wildlife populations and maintain food security in subsistence-oriented communities.

    Full Text Available In this study, milk and blood samples collected simultaneously from 532 trade cows to be slaughtered at Bodija abattoir, Ibadan (southwestern, Nigeria were examined for antibodies to Brucella using the milk ring test (MRT and the rose bengal test (RBT. Overall, 18.61%of the milk samples were positive according to the MRT, while 9.77 % of the serum samples were positive according to the RBT. The difference was highly significant (Chi-square value 16.33; P<0.05; only 32 (6.02 % of the samples were positive for both tests. The Red Bororo breed of cattle and the White Fulani had the highest positive rates, namely 20.93 % and 11.69%for the MRT and RBT respectively.No conclusion can be drawn about sensitivity because we do not know the true status of the animals tested. It is, however, obvious that although the MRT and RBT are 1st-line screening tests for brucellosis in cows in some countries, their lack of specificity is of concern. Therefore, the requirement for other confirmatory tests that are more specific should be considered for control and eradication of the disease, especially in Nigeria.

    Full Text Available The comparative efficacy of Rose Bengal Plate Test (RBPT and Milk Ring test (MRT was calculated in terms of sensitivity and specificity for the diagnosis of bovine brucellosis in cows (Group A and buffaloes (Group B from Lahore and Okara districts of Punjab, Pakistan. Using bacterial growth as a gold standard RBPT showed high sensitivity values of 100% in both groups. While its specificity was 96.29% (Group A and 90.62% (Group B. On the other hands MRT showed low sensitivity (80.0% in Group A; 86.6% in Group B while its specificity was 100% in all the animals of both groups. The calculated positive predictive and negative predictive values of both groups were in correspondence with their specificity and sensitivity values respectively. High sensitivity and low specificity of RBPT as compare to high specificity and low sensitivity of MRT in all groups suggested the poor efficacy of both tests used individually as compare to bacterial growth. In the continuation of this study polymerase chain reaction (PCR was evaluated for its diagnostic efficacy of quick Brucella abortus isolation from same samples. PCR conducted on serum samples gave more positive results than on milk samples. Therefore, the combination of both conventional tests alongwith serum PCR can be recommended. [Vet.

    Full Text Available Human brucellosis is most commonly diagnosed by serology based on agglutination of fixed Brucella abortus as antigen. Nucleic acid amplification techniques have not proven capable of reproducibly and sensitively demonstrating the presence of Brucella DNA in clinical specimens. We sought to optimize a monoclonal antibody-based assay to detect Brucella melitensis lipopolysaccharide in blood by conjugating B. melitensis LPS to keyhole limpet hemocyanin, an immunogenic protein carrier to maximize IgG affinity of monoclonal antibodies. A panel of specific of monoclonal antibodies was obtained that recognized both B. melitensis and B. abortus lipopolysaccharide epitopes. An antigen capture assay was developed that detected B. melitensis in the blood of experimentally infected mice and, in a pilot study, in naturally infected Peruvian subjects. As a proof of principle, a majority (7/10 of the patients with positive blood cultures had B. melitensis lipopolysaccharide detected in the initial blood specimen obtained. One of 10 patients with relapsed brucellosis and negative blood culture had a positive serum antigen test. No seronegative/blood culture negative patients had a positive serum antigen test. Analysis of the pair of monoclonal antibodies (2D1, 2E8 used in the capture ELISA for potential cross-reactivity in the detection of lipopolysaccharides of E. coli O157:H7 and Yersinia enterocolitica O9 showed specificity for Brucella lipopolysaccharide. This new approach to develop antigen-detection monoclonal antibodies against a T cell-independent polysaccharide antigen based on immunogenic protein conjugation may lead to the production of improved rapid point-of-care-deployable assays for the diagnosis of brucellosis and other infectious diseases.

    Brucellosis is a crucial zoonosis caused by Brucella, which has some traits of wide hosts, great infectivity, serious damage and difficulty in cure. In recent years, brucellosis rebounds worldwidely, and it is especially serious in China. It causes great losses to farming and people's health. Vaccination is one of the most effective measures used to control the disease, and the application of appropriate vaccine decides the brucellosis controlling effect. Up to now, therer are several attenuated vaccines used in domestic and abroad, in which the most widely used vaccines were B. abortus strain 19 (S19), B. melitensis Rev.l (Rev.1), B. suis strain 2 (S2), and rough strain B. abortus 51 (RB51), and each vaccine has its advantages and disadvantages. Scientists are now trying to develop more effective vaccines to deal with increasingly serious brucellosis epidemic situation. They are now constructing recombinant and molecular marker strains, DNA vaccines and subunit vaccines. Some conventional and new-style vaccines were reviewed in this paper.%布鲁氏菌病(布病)是由布鲁氏菌引起的一种重要的人兽共患病,近几年在世界范围内呈反弹趋势,我国尤其严重,该病对畜牧业和人类健康均构成严重威胁.疫苗免疫是预防和控制布病的重要措施之一,选择和使用有效的布病疫苗关系到布病防控的成效.迄今国内外已有多个弱毒活疫苗在使用,其中使用最为广泛的有光滑型牛种S19株、羊种Rev.1株、猪种S2株,以及粗糙型牛种RB51株.不同疫苗各有其优缺点,科学家们正试图研发更理想的布病疫苗.目前人们正通过基因工程技术构建重组弱毒疫苗、分子标记疫苗、DNA疫苗以及亚单位疫苗.对布病疫苗的应用及新型疫苗的研究现状作一综述.

    We report the evolution of an outbreak of bovine brucellosis (Brucella abortus) in the region of Extremadura (Spain) involving more than 1000 herds and nearly 40,000 animals. S19 vaccination of young cattle combined with a test and slaughter strategy did not result in a rapid decrease in herd prevalence and animal incidence; these parameters showed a constant decreasing trend only when a combination of restriction of cattle movements, increased test frequency, S19 vaccination and mass RB51 vaccination (with yearly revaccinations) were applied to all susceptible populations. These measures were applied for 5 years; abortions following RB51 vaccination of pregnant cows were limited to the first inoculation and the involvement of the vaccine strain could only be demonstrated in 78 out of 897 abortions. Our results demonstrate the usefulness - and lack of significant side effects - of RB51 mass vaccination as a complementary tool to control bovine brucellosis outbreaks in areas where the disease cannot be contained using more conservative approaches.

    Brucellosis was one of the important zoonosis caused by different kinds of Brucella spp. The most common clinical manifestations of the infected animals were abortion,placentitis,epididymitis and orchitis. In human being,brucellosis was a debilitating and chronic disease,which could injure a variety of organs. Although etiology identification was a conventional and effective diagnosis method,but it was strict with personal safety and requirements of laboratory. The process of isolating pathogen from infected animal was time-consuming and hazardous,so it was difficult to be popularized in the clinical diagnosis of brucellosis. The serological diagnosis method showed good specificity and sensibility,but it was hard to identify various wild strains and the infection of vaccine strain. In view of the above factors,it was necessary to in-depth develop new diagnosis method of brucellosis with better specificity, sensibility and stability in the veterinary clinical practice. The diagnosis methods of brucellosis were reviewed from the bacteriological,serological and molecular biology aspects, so as to provide references for the related studies.%布鲁菌病是一类由各型布鲁菌感染而引起的重要的人畜共患病之一。被感染的动物最常见的临床表现为流产、胎盘炎、附睾炎、睾丸炎等。人感染布鲁菌病后,多呈慢性经过,可损害人体多种器官。虽然病原学鉴定是一种常规有效的诊断布鲁菌病的方法之一,但由于其对操作人员安全以及实验室级别的要求非常严格,加之从患病动物体内分离病原体的过程既耗时又具有危险性,在布鲁菌病临床诊断实践中推广应用困难。布鲁菌病血清学诊断方法显示出较高的特异性和敏感性,但难以鉴别布鲁菌各型野毒株以及疫苗株感染。鉴于上述问题,深入开发和研制更高特异性、敏感性和稳定性的新型布鲁菌病诊断方法在兽医临床实践中势在必

    Full Text Available O uso do leite "in natura" por certos consumidores, tem se constituído num sério problema de Saúde Pública. Desta forma, foi efetuado um levantamento da situação dos rebanhos bovinos na região de Ribeirão Preto, SP (Brasil para se verificar a prevalência de brucelose. A partir da detecção de um rebanho leiteiro brucélico foram investigados os consumidores humanos do leite suspeito, segundo algumas características, tais como: sexo, cor, idade, ocupação, estado civil, tempo de residência na área, tempo de uso do leite suspeito, tipo de leite ingerido, quantidade de ingestão diária do leite, condições de saúde, uso de medicamentos e morbidades referidas na época do estudo. Foram feitas provas sorológicas para diagnóstico de brucelose no rebanho leiteiro e na população humana consumidora do leite. Observou-se que cerca de 8% das vacas em lactação na época do levantamento foram consideradas brucélicas. Entre os consumidores não se observou casos de sorologia positiva para brucelose. Concluiu-se que: apesar da importância da brucelose como zoonose, ela continua endêmica no nosso meio criatório; a fervura do leite é uma medida eficaz e deve ser preconizada nas regiões onde o leite é consumido "in natura", como medida de escolha em saúde pública.The use of "in natura" milk by some communities became a serious problem in Public Health.

    Full Text Available Test evaluation in the absence of a gold standard test was conducted for the diagnosis and screening of bovine brucellosis using three commercially available tests including RBPT, CFT, and I-ELISA in National Animal Health Diagnostic and Investigation Center (NAHDIC Ethiopia. A total of 278 sera samples from five dairy herds were collected and tested. Each serum sample was subjected to the three tests and the results obtained were recorded and the test outcomes were cross-classified to estimate the sensitivity and specificity of the tests using Bayesian model. Prior information generated on the sensitivity and specificity of bovine brucellosis from published data was used in the model. The three test-one population Bayesian model was modified and applied using WinBug software with the assumption that the dairy herds have similar management system and unknown disease status. The Bayesian posterior estimate for sensitivity was 89.6 (95% PI: 79.9–95.8, 96.8 (95% PI: 92.3–99.1, and 94 (95% PI: 87.8–97.5 and for specificity was 84.5 (95% PI: 68–94.98, 96.3 (95% PI: 91.7–98.8, and 88.5 (95% PI: 81–93.8 for RBT, I-ELISA, and CFT, respectively.

    Background:In recent years,the incidenc of spinal brucellosis presents a rising trend. It is very difficult to clari-fy a diagnosis for spinal brucellosis because it lacks specific diagnostic criteria. Objective:To retrospectively analyze clini-cal data of 16 cases of spinal brucellosis and to summarize diagnostic rule, treatment tactic and prognosis of the disease. Methods:From January 1999 to July 2015, 16 patients with spinal brucellosis were treated in our hospital. Their medical re-cords were collected. Complaints, clinical manifestations, serological and bacteriological results, imaging changes, clinical treatment and prognosis were analyzed. Results:There were 8 males and 8 females with a mean age of 49.25 years. They complained mainly for severe back pain or hip pain, and all had a history of exposure to cattles. The average of history was 3 months. Laboratory examination:ESR became faster in 14 patients (87.5%). The amount or percentage of monocytes in-creased in 15 patients (93.75%). In all 16 patients, CRP increased while white blood cell count kept normal. Blood cultures were negative, and the positive rate of bacterial culture was 50%. Lesions mainly involved lumbar vertebrae (13 cases, 81.25%). Imaging:X-ray and CT showed a parrot's beak appearance in 7 cases (63.6%);hypointense on T1-weighted imag-es, equal signal intensity on T2-weighted and hyperintense on FLAIR sequences of the intervertebral disc in MRI were found in 10 cases (71.4%). Nine patients underwent surgery and seven patients were treated by oral medicine. The mean du-ration of follow-up was 20.22 months (range, 2.5-197.0 months). Good prognosis was achieved in all patients. Conclusions:Once people have the following characteristics, spinal brucellosis should be highly suspected: severe low back pain, in-creased monocytes or mononuclear cell percentage, a history of exposure to cattle, a parrot's beak appearance in X-ray and CT, hypointense on T1-weighted images of the intervertebral

    In order to provide a reference for choosing an appropriate serological test method for bovine brucellosis in clinical detection,4 serological tests for bovine brucellosis detection were compared and analyzed. 294 bovine serum samples were tested by Rose Bengal Plate Agglutination Test(RBT),Serum Agglutination Test(SAT),Enzyme-Linked Immunosorbent Assay(ELISA)and Complement Fixation Test(CFT),respectively. The coincidence rate and Kappa were compared between RBT and ELISA,SAT and CFT,respectively. The sensitivity and specificity of the 4 tests were compared using CFT as a standard. The coincidence rate of RBT and ELISA,SAT and CFT was over 95% as well as the Kappa values > 0.75. Taking CFT as a standard,the sensitivity of RBT and ELISA was better,but it exised a certain false positive. The specificity of SAT was better,but it existed a certain false negative. ELISA had better sensitivity and speci-ficity than RBT and SAT. RBT and ELISA were suitable for screening,and CFT was suitable for definite diagnosing in clinical detection. It was better to choose more than two tests for diagnosis of bovine brucellosis.%[目的]为在布鲁氏菌病临床检疫中选择可靠的血清学检测方法提供参考。[方法]对采集的294份牛血清样品用虎红平板凝集试验(RBT)、试管凝集试验(SAT)、酶联免疫吸附试验(ELISA)和补体结合试验(CFT)进行布鲁氏菌病抗体检测,比较RBT与ELISA,SAT与CFT的符合率及Kappa值,以CFT作为判定标准,比较四种检测方法的敏感性和特异性。[结果] RBT与ELISA、SAT与CFT检测方法的符合率高达到95%以上,且Kappa值均大于0.75。以CFT作为判定标准,RBT和ELISA的敏感性较好,但有假阳性;SAT的特异性较好,但有假阴性。综合比较认为ELISA的敏感性和特异性都比较理想。[结论]临床工作中使用RBT或ELISA对布鲁氏菌病进行初筛,用CFT进行复核确诊,通过两种或两种以上的血清学检

    Objective To analyze epidemic characteristics and factors of brucellosis in Anyang city so as to provide scientific basis for prevention and control. Methods The data of epidemic situation and monitoring of brucellosis in Anyang city from 2004 to 2011 has been statically analyzed. Results The incidence rate has increased year by year and epidemic area has enlarged continuously in Anyang city. 36. 30% of townships including towns and offices had reported the cases of incidence; Farmers gave priority to other people on the infection; the incidence rate of male was more than that of female,middle and aged old patients with brucellosis were majority and the tendency of this disease was aging, which were consistent with the result of serologic test. There were cases throughout the whole year,having incidence peak in late spring and early summer,which was not obviously, 32. 99 % of these cases happened on April and May. All of the cases were sporadic. The types of infection of brucellosis were diverse, which were mainly contact infection. Patients'clinical symptoms were typical, but the definite diagnosis was not in time. It cost more than 30 days from falling ill to definite diagnosis for 55. 15 % of the cases, which resulted in more misdiagnosis and mistreatment. Not meet the requirements of quarantine and immune of foreign brutish, short of personal health consciousness and lack of protective measures were the main factors which caused brucellosis. Conclusion Government leadership, departments coordination and supervision should be strengthen. Quarantine and immune measures between livestock should be carried out, as well as strengthen propaganda and training on brucellosis so as to dispose well the disease livestock and personal protection, induce and control the outbreak of brucellosis through taking all of above measures.%目的 分析安阳市布鲁杆菌病(布病)的疫情特征及其流行因素,为制定防控措施提供科学依据.方法 对安阳市2004

    Disease caused by Brucella spp. represents the most common bacterial zoonotic infection worldwide. The distribution and public health impact of these infections in Nepal's mountain regions are poorly characterized. This cross sectional study assesses the burden of brucellosis on transhumant pastoralists and their yak in and around Shey Phoksundo National Park, Nepal. Objectives were to: (1) estimate individual animal prevalence of Brucella-seropositive yak, (2) identify herd- and individual-level risk factors associated with Brucella seropositivity in individual yak, and (3) identify herd-level risk factors associated with reported human brucellosis-like symptoms in a household. A case of household symptoms was defined as the reported occurrence within the previous year of at least one of three acute symptoms (chills, fever, night chills) and one of two chronic symptoms (joint pain, swollen joint(s)) in one or both of two individuals interviewed in a household. Two-hundred-ninety-seven yak from 61 herds were sampled, and 61 household questionnaires were completed. Estimated true prevalence was 0.22 (95% CI: 0.17; 0.28). Poisson regression with generalized estimating equations was used to account for repeated measures within a cluster (herd). Yak in herds reporting abortion occurrence within the previous year were 2.3 times more likely to be seropositive than those in herds not reporting abortion (95% CI: 1.2; 4.2, p = 0.01). For every 10 animal increase in herd number, individual animal seropositivity risk increased by 30% (95% CI: 10%; 50%, p = 0.001). Male yak were 0.7 times as likely to be seropositive as female yak (95% CI: 0.5; 0.9, p = 0.01). Three to five year old yak were 2 times more likely to be seropositive than yak 5 years old were 4.9 times more likely to be seropositive than yak 1 reactor, and was 3.6 (95% CI: 1.4; 9.2, p = 0.008) times greater for households reporting the practice of raw milk consumption. These results indicate that yak

  18. Solution structure of an arsenate reductase-related protein, YffB, from Brucella melitensis, the etiological agent responsible for brucellosis

    International Nuclear Information System (INIS)

    B. melitensis is a NIAID Category B microorganism that is responsible for brucellosis and is a potential agent for biological warfare. Here, the solution structure of the 116-residue arsenate reductase-related protein Bm-YffB (BR0369) from this organism is reported. Brucella melitensis is the etiological agent responsible for brucellosis. Present in the B. melitensis genome is a 116-residue protein related to arsenate reductases (Bm-YffB; BR0369). Arsenate reductases (ArsC) convert arsenate ion (H2AsO4−), a compound that is toxic to bacteria, to arsenite ion (AsO2−), a product that may be efficiently exported out of the cell. Consequently, Bm-YffB is a potential drug target because if arsenate reduction is the protein’s major biological function then disabling the cell’s ability to reduce arsenate would make these cells more sensitive to the deleterious effects of arsenate. Size-exclusion chromatography and NMR spectroscopy indicate that Bm-YffB is a monomer in solution. The solution structure of Bm-YffB shows that the protein consists of two domains: a four-stranded mixed β-sheet flanked by two α-helices on one side and an α-helical bundle. The α/β domain is characteristic of the fold of thioredoxin-like proteins and the overall structure is generally similar to those of known arsenate reductases despite the marginal sequence similarity. Chemical shift perturbation studies with 15N-labeled Bm-YffB show that the protein binds reduced glutathione at a site adjacent to a region similar to the HX3CX3R catalytic sequence motif that is important for arsenic detoxification activity in the classical arsenate-reductase family of proteins. The latter observation supports the hypothesis that the ArsC-YffB family of proteins may function as glutathione-dependent thiol reductases. However, comparison of the structure of Bm-YffB with the structures of proteins from the classical ArsC family suggest that the mechanism and possibly the function of Bm-YffB and other

    Full Text Available The official methods specified in the national bovine and ovine/caprine brucellosis eradication plan are the Rose Bengal and complement fixation tests. In the current phase of the eradication plan, it is often difficult to interpret the results obtained with the official tests. Consequently, additional tests that offer greater sensitivity and specificity are thus required. For this reason, two methods, the indirect chemiluminescence enzyme-linked immunosorbent assay (i-ELISA CL and the competitive chemiluminescence ELISA (c-ELISA CL that use a chemiluminescent substrate to determine anti-Brucella antibodies in bovine and ovine serum were validated. The methods are based on the detection of anti-Brucella antibodies in serum by catalysis of a chemiluminescent enzyme substrate (luminol/ H2O2/enhancer system by peroxidase conjugated to secondary anti IgG antibodies in i-ELISA CL and to monoclonal anti-lipopolysaccharide (LPS antibodies in c-ELISA CL. From the results obtained, a cut-off of 60% for bovine serum and 37.5% for ovine serum, expressed as positivity rate (PR, were established Using these cut-off values, for the i-ELISA CL, 100% sensitivity and specificity was obtained for bovine serum and 100% sensitivity and 99.8% specificity for ovine serum. Cut-off values of 30% for bovine serum and 40% for ovine serum, expressed as inhibition rate, were selected for c-ELISA CL, which ensured 100% sensitivity and specificity in both cases.
