“…The Collaborating Center for Animal Health of the Faculty of Veterinary Medicine and Animal Science at the University of São Paulo was instructed to standardize methodology and perform cross-sectional studies in all Federal Units in order to choose the most appropriate strategies and perform management processes (POESTER et al, 2009). Initial studies have been conducted in 18 Federative Units, representing 85% of the actual Brazilian cattle population.…”

The study was conducted to verify the efficacy of the bovine brucellosis vaccination program implemented by the state of Mato Grosso, using prevalence as an indicator. The state was divided into four regions: Pantanal, Milk, Fattening, and Breeding. For each region, a predetermined number of properties were selected and blood samples were taken from randomly chosen female animals, aged 24 months or greater. Sera from the animals were initially screened with a buffered acidified plate antigen, and confirmed using complement fixation. In each property, a questionnaire was used in order to identify the risk factors associated with the disease. In the state, the prevalence rate of infected herds was 24.0% [21.3; 26.8] and the prevalence rate of infected animals was 5.1% [3.5; 7.2]. The prevalence rates of infected herds and animals in each region were as follows: 21.2% and 6.4% in the Pantanal region, 17.2% and 3.7% in the Milk region, 34.0% and 7.2% in the Fattening region, and 24.3% and 4.4% in the Breeding region. Bovine brucellosis in the state is associated with the introduction of breeding, herd size, pasture sharing, and farms used for mixed and beef purposes. Therefore, in order to improve control of bovine brucellosis, it is proposed that the state of Mato Grosso intensify its prophylactic program, primarily its vaccination strategy. There has been a reduction in the prevalence of infected herds since 2002; however, there remains a high prevalence of infected herds and animals throughout the state. Additionally, the use of non-inducing antibodies vaccine should be encouraged, especially in the Pantanal region where the management of the animals is complicated by the flood and ebb cycle. The state should make greater efforts to educate producers on how to assess the breeding animals for brucellosis before introducing them into their properties as well as avoid shared grazing among herds of unknown health conditions. ResumoO estudo foi realizado para se verificar a eficácia do programa de vacinação contra brucelose bovina implementado pelo estado de Mato Grosso, utilizando-se a prevalência como indicador. O Estado foi dividido em quatro regiões: Pantanal, Leite, Engorda e Cria. Para cada região, um número preestabelecido de propriedades foi selecionado e em cada uma delas foram colhidas amostras de sangue de fêmeas com idade igual ou superior a 24 meses, aleatoriamente escolhidas. Os soros dos animais foram submetidos a um protocolo de testes em série, com triagem pelo teste com Antígeno Acidificado Tamponado e confirmação pela Fixação do Complemento. Em cada propriedade foi aplicado um questionário para individualizar os fatores de riscos associados à doença. No estado, a prevalência de focos foi 24,0% [21,3; 26,8] e a de animais 5,1% [3,5; 7,2]. As prevalências de focos e de animais nas regiões foram 21,2% e 6,4% no Pantanal, 17,2% e 3,7% na região Leite, 34,0% e 7,2% na região de Engorda e 24,3% e 4,4% na região de Cria.

“…Bovine brucellosis, a zoonotic disease causing economic losses, hinders the development of the beef production chain, and can result in barriers to international trade in animals and animal products (PAULIN; FERREIRA NETO, 2002NETO, , 2003. These are measures in line with the recommendations of the OIE (World Organisation for Animal Health), and are sufficiently flexible as to allow implementation of the program in heterogeneous regions of Brazil (LAGE et al, 2006;POESTER et al, 2009). …”

This study aimed to evaluate the effectiveness of a bovine brucellosis vaccination program in Rio Grande do Sul, with prevalence as the indicator, and to identify risk factors for the disease. The state was divided into seven regions. For each region, a predetermined number of properties were randomly sampled, in which a pre-established number of randomly selected females aged over 24 months were tested. The serodiagnosis protocol consisted of a screening test using buffered acidified antigen, followed by a confirmatory test using 2-mercaptoethanol. An epidemiological questionnaire was utilized to identify possible risk factors associated with bovine brucellosis. In the state of Rio Grande do Sul, the prevalence of infected herds was found to be 3.54% [2.49-4.88], and the prevalence of infected animals was 0.98% [0.57-1.57]. In assessments of specific regions, the infected herd prevalence ranged from 0.66% to 3.09%, and among the animals, from 0.06% to 2.03%. In herds comprising 15 or more cows, beef type and pasture sharing emerged as risk factors for bovine brucellosis in the state. The epidemiological status of bovine brucellosis in Rio Grande do Sul has remained unchanged since 2004, even though adequate vaccination coverage has been recorded since 2009. Thus, the state should continue its vaccination program, with emphasis on the quality of the process and on encouraging the use of nonantibody inducing vaccines. In addition, the state must make a greater effort to educate producers on the importance of testing for brucellosis in breeding animals before introducing them onto their properties, and on the importance of avoiding shared grazing among herds whose health conditions are unknown. preestabelecido de propriedades nas quais foi testado um número também preestabelecido de fêmeas com idade igual ou superior a 24 meses, aleatoriamente selecionadas. O protocolo do sorodiagnóstico foi composto de triagem com o teste do antígeno acidificado tamponado, seguido de teste confirmatório dos positivos com o teste 2-Mercaptoetanol. Nas propriedades foi aplicado um questionário epidemiológico sobre possíveis fatores de riscos associados à brucelose bovina. No estado do Rio Grande do Sul, a prevalência de focos foi de 3.54% [2.49 -4.88] e a de animais 0.98% [0.57 -1.57]. Nas regiões, as prevalências de focos variaram de 0.66% a 9.03% e a de animais de 0.06% a 2.03%. Rebanhos com 15 ou mais vacas, tipologia corte e compartilhamento de pastagens emergiram como fatores de risco para brucelose bovina no estado. A situação epidemiológica da brucelose bovina no Rio Grande do Sul manteve-se estável desde 2004, a despeito de boas coberturas vacinais terem sido registradas a partir de 2009. Assim, o estado deve continuar seu programa de vacinação, dando ênfase para a qualidade do processo e estimulando a utilização da vacina não indutora de anticorpos. Adicionalmente, o estado deve realizar um grande esforço de educação para que os produtores testem os animais de reprodução para brucelose antes de introduzi-los em sua...

“…It was found that most qualified professionals supervised (62.98%) adopt the model of official certificates of vaccination and prescriptions for the purchase of vaccines (Table 3). This fact is important, since studies on the prevalence of bovine brucellosis in the PNCEBT demonstrated that well-structured and administered programs reach good levels of control, with significant reduction in prevalence (Poester et al, 2009). For this structure, it is essential that professionals maintain considerable level of organization and standardization of procedures.…”

The inspection of qualified professionals is an important action of the National Programme for Control and Eradication of Animal Brucellosis and Tuberculosis (PNCEBT). The data for this study were obtained by compiling reports of 63 inspections in loco of qualified private veterinarians between 2008 and 2011 in the state of Espírito Santo, Brazil. Through the findings of this study, it was observed that all inspected professionals are regularly registered in the CRMV-ES, nevertheless it was found pending issues regarding the registration to conduct vaccinations against brucellosis. It was observed that most professionals keep the infrastructure and equipment for conducting tuberculosis and brucellosis tests. The majority adopts the official models of certification, however there is a significant delay in sending reports of actions, and many professionals reported a lack of demand for certification of properties.
