Comparison of infection by Brucella spp. in free-ranging and captive wild animals from São Paulo State, Brazil J. Venom. Anim. Toxins incl. Trop. Dis.
Antunes,JMAP; Machado,GP; Costa,LF; Fornazari,F; Cipriano,JRB; Appolinário,CM; Allendorf,SD; Bagagli,E; Teixeira,CR; Megid,J.
The aim of the current study was to evaluate the infection rate by Brucella spp. in wild and in captive animals. Serum samples from 121 animals (94 free-ranging and 27 captive) of different mammal species were evaluated. Sera were submitted to rose Bengal test (RBT) for screening and serum agglutination tests (SAT) and 2-mercaptoethanol test (2-ME) for confirmatory results. Nine animals (five free-ranging and four captive) tested positive in RBT, but negative in the confirmatory tests. Several domestic animal diseases that have control programs are not focused on wild reservoirs, such as brucellosis in Brazil. The study of new reservoirs in wildlife is essential to prevent emerging diseases.

Disease and Behavioral Dynamics for Brucellosis Control in Elk and Cattle in the Greater Yellowstone Area AgEcon
Xie, Fang; Horan, Richard D..
This paper investigates private responses and ecological impacts of policies proposed to confront the problem of brucellosis being spread from elk to cattle in Wyoming. The policies consist of combinations of changes in elk feeding and population levels. Farmers' responses to these dynamics are modeled along with the associated impacts to livestock population dynamics. Our findings suggest that feedbacks between jointly determined disease dynamics and decentralized economic behavior matter, and the elk feedgrounds do not actually generate economic harm to the individual farmers.

Optimal Control of Brucellosis in Bison in the Yellowstone National Park Area AgEcon
Xie, Fang; Horan, Richard D..
Brucellosis is a highly infectious bacterial disease that causes infected females to abort their calves. It has caused devastating losses to U.S. farmers over the last century. The only known focus of Brucellosis left in the nation is wildlife such as bison and elk in the Greater Yellowstone Area. Vaccination and test-and-slaughter have been applied to brucellosis management in bison, and there has been discussion that a combination of both could potentially eradicate the disease in the Yellowstone National Park. However, there is no study on how to allocate resources between the two actions. This paper investigates the optimal allocation of these two selective management options, in a bioeconomic framework, when there are both existence and recreational...

Serological survey of Mycobacterium bovis, Brucella abortus and Borrelia burgdorferi in water buffaloes in the northern region of Brazil Rev Salud Anim.
Barbosa da Silva,Jenevaldo; da Fonseca,Adivaldo Henrique; Barbosa,José Diomedes.
The largest buffalo herds are in the northern region of Brazil, so few studies have been conducted to assess the prevalence of selected parasitic diseases in buffalo herds. The present study was therefore conducted to research the epidemiology of Borrelia burgdorferi, Mycobacterium bovis and Brucella abortus in water buffaloes in the north region of Brazil. A total of 4796 buffalo blood samples were randomly collected from five provinces and simultaneously analyzed by ELISA, tuberculin test, CFT and 2ME. The occurrence of B. burgdorferi in buffalo was 75% by ELISA. The tuberculin testing prevalence of M. bovis was 4.6%. The overall prevalence of B. abortus was 4.8% and 4.6% by CFT and 2ME, respectively. Thus, it is concluded that all agents studied were...

Falcão,M.V.D.; Santana,V.L.A.; Corrêa,F.N.; Tenório,J.A. B.; Mota,R.A..
ABSTRACT Brucellosis is an infectious disease caused by bacteria of the genus Brucella spp. with diagnosis based on use of serological techniques. The present study aimed to develop and standardize a western blotting (WB) test for detection of antibodies against B. abortus. Samples from two groups of cattle were analyzed: group I: 60 serum samples from true positive and true negative vaccinated animals (30 positive samples from infected animals according to rose bengal test (RBT), 2-mercaptoethanol, serum agglutination test (SAT) and complement fixation test (CFT) and 30 RBT negatives samples); group II: 383 field samples (90 positive and 293 CFT negative sera). The most reactive band in the western blotting, which properly identified and separated...

Brucella spp. in equines slaughtered in the south region of Brazil Arq. Bras. Med. Vet. Zootec.
Santos,R.F.; Silva,G.C.P.; Assis,N.A.; Mathias,L.A..
ABSTRACT Bacteria of the genus Brucella are widespread in many countries. These microorganisms can infect humans and many wild and domestic animal species. These bacteria have zoonotic potential, and can cause economic and public health problems since they can be transmitted by direct contact with sick animals, through consumption of contaminated milk, raw meat and its derivatives (Soares et al., 2015). Brucellosis is considered a chronic evolving disease, unusual in horses, predominantly caused by Brucella abortus. However, it is not characterized by reproductive disorders in horses, but primarily by abscess in the cervical region, bursa, tendons, and joints. Transmission is likely to occur via ingestion of contaminated water and pastures, especially in...

Indirect ELISA for diagnosis of Brucella ovis infection in rams Arq. Bras. Med. Vet. Zootec.
França,S.A.; Mol,J.P.S.; Costa,E.A.; Silva,A.P.C.; Xavier,M.N.; Tsolis,R.M.; Reis,J.K.P.; Paixão,T.A.; Santos,R.L..
Brucella ovis is a major cause of epididymitis in sexually mature rams, resulting in subfertility, infertility, and economic losses for the sheep industry worldwide. The aim of this study was to develop an indirect ELISA (iELISA) using recombinant proteins, namely rBoP59 and rBP26, as antigens for serological diagnosis of B. ovisinfection. The BoP59 and BP26 recombinant proteins were expressed in E. coli and purified by affinity chromatography. Antigenicity was tested by Western blot and iELISA. Standardization of iELISA was performed with 500ng and 1µg BoP59 and rBP26 per well, testing serum from uninfected and experimentally infected rams. rBP26 was effective in distinguishing positive from negative rams. The rBP26 iELISA developed in this study is the...

Polymorphisms of the coding region of Slc11a1 (Nramp1) gene associated to natural resistance against bovine brucellosis Arq. Bras. Med. Vet. Zootec.
Paixão,T.A.; Martinez,R.; Santos,R.L..
Brucelose bovina causada por Brucella abortus é uma importante doença zoonótica, caracterizada pela ocorrência de aborto durante o último trimestre da gestação, o que resulta em diminuição da fertilidade da produção de leite em vacas. A identificação de genes associados à resistência natural contra brucelose tem sido investigada com o objetivo de selecionar animais resistentes à doença. Em bovinos, é controversa a resistência natural contra B. abortus associada ao polimorfismo da região 3' UTR do gene Slc11A1 (Nramp1). Polimorfismos localizados na sequência codificadora de Slc11A1 têm sido identificados em bovinos, contudo a influência sobre a resistência natural contra brucelose não é conhecida. No presente estudo, três novos polimorfismos do gene Slc11A1...

Cost-benefit analysis of sheep and goat brucellosis vaccination with Rev.1 in the north of Portugal from 2000 to 2005 Arq. Bras. Med. Vet. Zootec.
Coelho,A.M; Pinto,M.L; Coelho,A.C.
In the North of Portugal, a mass vaccination programme of small ruminants was conducted from 2001 to 2004. A study of cost-benefit was carried out for the 2000/2005 period to ascertain the economic benefits of this strategy. In order to estimate the cost of the zoonosis, the compensation costs paid to farmers for culled animals in the Brucellosis Eradication Campaign, data from vaccine Rev. 1 costs, and costs of people internment due to brucellosis were studied. An increase in the cost was observed from 2000 to 2001 (aproximately US$ 110,000), essentially due to compensation for culled animals, but also from vaccination and human internment costs. However, a progressive decrease was observed from 2001 to 2004 (from more than US$1,200,000 in 2001 to...

Contribuição ao conhecimento da incidência da brucelose no Estado do Paraná (Brasil) BABT
Palmquist,Oscar K..
O rebanho bovino paranaense apresenta um índice de brucelose relativamente alto, particularmente no Norte e Leste do Estado. O gado leiteiro revelou um índice de 7,90%, com um foco grave no Município de Castro (29,92%). Bovinos criados em regime extensivo de pastagens naturais se apresentam com menor grau de infecção, pois a maior incidência foi encontrada no Norte do Estado, onde, regra geral, os campos são constituídos de pastos artificiais.

Leite,Ricardo de Miranda Henriques; Thompson,James Alan; Gonçalves,Vítor Salvador Picão; Leite,Rômulo Cerqueira; Bandeira,Dimas A.; Lage,Andrey Pereira.
A serosurvey was conducted to estimate the prevalence of bovine brucellosis in the State of Paraíba, Brazil. A random sample of six municipalities was selected from each of three ecoregions of the State: the Agreste/Litoral region (1), the Cariri/Curimatau region (2) and the Sertão region (3). These 18 municipalities were divided in quadrants and one herd was selected at random from each quadrant. The sampling scheme included herds with more than 50 bovines, which excludes small-holder subsistence livestock production. At least 32 animals were sampled within each herd, stratified in four age categories, as follows: (1) at least 8 animals under 6 months of age, (2) at least 8 animals of 7 to 18 months of age, (3) at least 8 animals of 19 to 30 months of age...

DAFFNER,José; ABALOS,Pedro; PINOCHET,Lautaro; SCORTTI,Mariela; URCELAY,Santiago.
Three soluble antigens were compared by radial immunodiffusion (RID) and agar gel immunodiffusion (AGID) tests: a native haptene (NH) from Brucella melitensis 16M, and a polysaccharide (PS) from B. abortus 1119-3, both obtained by non-hydrolytic methods, and the (O-Chain) polysaccharide extracted also from B. abortus 1119-3 but using an hydrolytic method. Three groups of bovine sera were tested: a) Naturally infected (n = 76); b) Non-infected (n = 130) and c) S-19 vaccinated (n = 61); the sensitivity (Se), the specificity (Sp) and the ability to differentiate vaccinated (ADV) were determined in each group a, b and c respectively. The highest Se in the RID test (84.3%) was achieved by NH; while the three antigens gave 100% Sp. The O-Chain showed 100% ADV in...

LANGONI,Helio; ICHIHARA,Sílvio Massaru; SILVA,Aristeu Vieira da; PARDO,Renata Bonini; TONIN,Flávia Bechelli; MENDONÇA,Lia Jeanne Pereira; MACHADO,José Aparecido Dorta.
Brucellosis is a chronic zoonosis that plays an important role in Public Health. Considering the lack of data in Brazil regarding its presence in raw milk and non-pasteurized dairy products, we determined the presence of brucellae in milk from brucellosis positive animals. The slide agglutination test (SAT), tube agglutination test (TAT) and TAT treated with 2-mercaptoethanol were used to identify positive animals in studied herds. For 3 days, 300 ml milk samples/cow (75 ml/teat) were collected from all productive quarters of the positive animals. These were mixed and centrifuged. Part of the pellet and of the supernatant were inoculated in Farrel and Brodie-Sinton (BS) media supplemented with antimicrobial agents. The inoculated plates and tubes were...

Unrecognized pediatric and adult family members of children with acute brucellosis BJID
Çiftdoğan,Dilek Yılmaz; Aslan,Selda.
Abstract Background and aim Brucellosis is an infectious, contagious and zoonotic disease that occurs worldwide. The family members of an index case of brucellosis may be especially susceptible, due to sharing the same source of infection and similar risk factors for brucellosis. In this study, we propose to screen pediatric and adult family members of brucellosis index cases for detecting additional unrecognized infected family members. Materials and methods 114 family members of 41 pediatric patients with brucellosis were evaluated. All family members completed a brief questionnaire and were tested by a standard tube agglutination test (STA). Results The majority of family members (n = 96, 84.2%) were children. Among the 114 family members, 42 (36.8%)...
