“…This study is extremely important since previous studies are restricted to the farm level (Lucas 2006) or are completely outdated (Brasil 1971). These data are highly relevant for establishing public policies for control and eradication programs.…”

“…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.…”

“…0.15% of infected cows and heifers); (vii) increase in the rate of replacement corresponding to 15% of the infected cows and heifers (the cost was calculated based on the difference of the value received by a slaughtered cow under sanitary conditions and the cost of a replacement cow); and (viii) replacement costs of infected bulls, considering roughly half of the seroprevalence of heifers and cows (as observed in the study by Minervino et al 2011), an average bull/ cow ratio of 1/25, and same approach for calculating replacement costs as calculated for females (item vi). Costs associated with veterinary assistance were calculated based on a previous study performed under field conditions in Brazil (Lucas 2006). Importantly, since this study is aimed to estimate losses, but not total cost of bovine brucellosis, in spite of its social importance, costs associated with human health were not considered as well as the costs of the Brazilian National Program for Control and Eradication of Brucellosis and Tuberculosis.…”

“…Importantly, since this study is aimed to estimate losses, but not total cost of bovine brucellosis, in spite of its social importance, costs associated with human health were not considered as well as the costs of the Brazilian National Program for Control and Eradication of Brucellosis and Tuberculosis. Except when stated otherwise, all estimated costs for dairy cattle were based on values previously reported by Lucas (2006), whereas estimated costs for beef cattle were based on Jorge Jr et al (2006). Reference values were updated based on current market values of milk and meat for dairy and beef cattle, respectively, which were based on values reported by the Centro de Estudos Avançados em Economia Aplicada (CEPEA/ESALQ 2013) for the month of January 2013.…”

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.

“…As informações obtidas com a aplicação do questionário epidemiológico permitiram caracterizar a pecuária leiteira na Regional de Pedreiras com predominância da raça Girolando, criação tipo semiconfinamento, o que pode favorecer a ocorrên-cia e a disseminação da doença em razão da proximidade entre animais portadores e suscetíveis, conforme também atestaram Nicoletti (1980) e Crawford et al (1990). A ordenhada é manual, uma vez ao dia, com bezerro ao pé, podendo estar associada com a transmissão da brucelose, pois o micro-organismo é eliminado pelo leite, e terneiros que se alimentam de vacas brucélicas podem contaminar o ambiente pela eliminação do agente com as fezes, uma vez que algumas bactérias não são destruídas pelas enzimas digestivas (Lucas, 2006).…”

RESUMO: Objetivou-se com este estudo estimar a frequência da brucelose em bovinos e em ordenhadores na região central do Maranhão. Foram escolhidas, no período de maio a outubro de 2013, de forma aleatória, 35 propriedades cadastradas na Agência Estadual de Defesa Agropecuária do Maranhão (AGED-MA) e analisados sorologicamente 525 bovinos com aptidão leiteira, hemossoros de 60 ordenhadores, além de ter sido aplicado questionário epidemiológico para investigar os fatores de risco associados à infecção. O protocolo de diagnóstico utilizado foi o teste de triagem com antígeno acidificado tamponado (AAT), e a confirmação dos reagentes ocorreu mediante os testes 2-mercaptoetanol (2-ME) e polarização fluorescente (TPF). A frequência de animais sororreagentes foi de 26/525 (4,95%) no teste AAT e 17/525 (3,23%) e 13/525 (2,47%) nos testes de 2-ME e TPF, respectivamente. A frequência de rebanhos foco, com pelo menos um animal soropositivo, foi de 9/35 (25,71%) e 8/3 (22,85%), nessa ordem. Referente aos ordenhadores, 1/60 (1,66%) foi reagente nos testes confirmatórios de 2-ME, TPF e fixação de complemento. O fator de risco associado à ocorrência da brucelose, na análise multivariada, foi presença de ovinos (odds ratio - OR=6,66; intervalo de confiança de 95% - IC95% 1,26-35,03). O estudo demonstrou que a brucelose está disseminada no rebanho leiteiro investigado, indicando a necessidade de melhorias nas ações de controle e erradicação da brucelose na região estudada.

In order to support the implementation of PNCEBT in Tocantins State, a study was conducted to characterize the epidemiological situation of the disease from February 2002 to august 2003. The State was divided into six areas with a homogeneous productive system (production circuits). For each area, a simple random sample was calculated, to estimate the prevalence both in farms and cows over two years old. To achieve this, 10 15 adult cows (over two years old) were sampled. A total of 20,908 sera from 1,842 farms were obtained. For the whole State of Tocantins, the prevalence of positive farms (or farms with at least one positive animal) was 21.22% [19.33;23.11]. When the production circuits were considered, the positive farms prevalences from the circuits 1, 2, 3 and 5 were significantly higher than the other circuits: 16.
