“…The frequency of BB in the Rio Branco microregion (10.6%) was well above the prevalence rate in the country (3.4%), but similar to the one reported in Pará (10.9%) (MINERVINO et al, 2011). The rates for the other northern states were 4.1, 4.4 and 6.2% in Roraima, Tocantins and Rondônia, respectively (OGATA et al, 2009;VILLAR et al, 2009;SOUZA et al, 2012).…”

Bovine brucellosis (BB) is a compulsory notifiable bacterial disease caused by Brucella abortus, which is responsible for severe reproductive disorders in cattle, considerable damages to trade and public health damage. The objectives of this study were to identify the frequency of BB and to analyze the risk factors in the dairy herds of the Rio Branco microregion, in the state of Acre, Brazil. Thus, 527-bovine-serological samples were submitted to the buffered acidified antigen test and to 2-mercaptoethanol. Risk factors were characterized by the administration of epidemiological questionnaires. The logistic regression test was used to evaluate the existence of a significant association between the variables. The frequency of BB in the Rio Branco microregion was 10.6% (56/527). The inappropriate destination of the aborted fetus and placental remnants (odds ratio — OR = 13.6), the slaughter of cattle within the property (OR = 3.4) and the age range above 4 years old (OR = 2.9) were the most significant risk factors identified by the logistic regression model. According to the results of this study, it is recommended to intensify BB control and prophylaxis measures in the microregion of Rio Branco, especially those related to sanitary and reproductive management in the livestock breeding.

“…Additional parameters for dimensioning the economic impact of bovine brucellosis in Brazil is the fact the total losses of about 892.7 million Reais is roughly equivalent to a little more than one billion liters of milk or more than 500 thousand fattened steers for slaughter. A comprehensive model was developed in this study, which was based on reliable epidemiological data (Alves et al 2009, Azevedo et al 2009, Rocha et al 2009, Chate et al 2009, Negreiros et al 2009, Klein-Gunnewiek et al 2009, Villar et al 2009, Marvulo et al 2009, Sikusawa et al 2009, Ogata et al 2009, Minervino et al 2011, on sound clinical parameters (Bernués et al 1997), and on scientifically determined economic variables appropriate for dairy (Lucas 2006) or beef cattle (Jorge Jr et al 2006). This model has an intermediate level of stringency.…”

Pesq. Vet. Bras. 33(6):759-764, junho 2013 759 RESUMO.-[Perdas econômicas devidas à brucelose bovina no Brasil.] A brucelose é uma zoonose de importân-cia mundial. Recentes dados epidemiológicos dessa doença foram obtidos por meio de estudos que abrangeram em torno de 90% do rebanho bovino do Brasil. Observa--se escassez de informações sobre o impacto econômico causado pela brucelose bovina, portanto, o objetivo do presente estudo foi estimar as perdas econômicas na pecuária brasileira. Gastos relacionados com as ocorrências de abortos, natimortos, subfertilidade, descartes involuntários, mortalidade, intervenções veterinárias, diminuição da produção de leite e de carne, foram considerados nos cálculos. As perdas devidas à brucelose bovina no Brasil foram estimadas em R$ 420,12 ou R$ 226,47 para cada fêmea infectada acima de 24 meses de idade em rebanhos de leite 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.

A study was conducted to verify that the State of Santa Catarina has maintained a low prevalence of bovine brucellosis, which would allow the state to move forward with implementing strategies for disease eradication. The state was divided into five regions. In each region, a predetermined number of randomly selected properties was sampled. In each property, blood samples were collected from randomly selected cows with ages equal to or greater than 24 months. Sera from the animals were submitted to a serial testing protocol, with screening by the buffered acidified antigen test and confirmation by the 2-mercaptoethanol test. In each property, a questionnaire was used to identify the risk factors associated with the disease. In the state, the prevalence rate of infected herds was 0.912% [0.297 -2.11] and infected animals was 1.21% [0.09 -4.97]. Relative to the earlier study in 2002, there was no difference. The risk factors associated with the condition of a herd infected with brucellosis were as follows: herd size ≥ 12 cows (OR = 7.47 [2.14 -34.34]) and the presence of flooded areas ). In view of the low prevalence, it is recommended that the state proceed with the implementation of eradication strategies that are based on a surveillance system structured to detect and eliminate infected herds, and supported by an effective compensation fund for the replacement of seropositive animals. Additionally, the State should make a significant effort to educate and supervise producers to ensure the testing of breeding animals for brucellosis before introducing them into their properties. Key words: Brucellosis. Prevalence. Risk factors. Surveillance System. Santa Catarina. Brazil. ResumoFoi realizado um estudo para verificar se Santa Catarina continua com baixas prevalências de brucelose bovina, permitindo ao estado avançar de forma segura no seu projeto de implementação de estratégias de erradicação da doença. O estado foi divido em cinco regiões e em cada uma delas foi amostrado um número preestabelecido de propriedades, aleatoriamente selecionadas. Em cada propriedade foram colhidas amostras de sangue de fêmeas com idade igual ou superior a 24 meses, também selecionadas aleatoriamente. Os soros dos animais foram submetidos a um protocolo de testes em série, com triagem (OR = 7,47 [2,34]) e a presença de áreas alagadiças (OR = 5,68 [1,13]). Tendo em vista a baixa prevalência, recomenda-se que estado deve dar seguimento à implementação de estratégias de erradicação, baseadas na estruturação de sistema de vigilância para detecção e saneamento de focos, apoiado por eficiente fundo de indenização para a reposição de animais positivos aos testes sorológicos. Adicionalmente, o estado deveria realizar um grande esforço de educação e de fiscalização, para que os produtores testem os animais de reprodução para brucelose antes de introduzi-los em suas propriedades.
