“…Resultados de alguns estudos soroepidemiológicos realizados em ovinos e bovinos no país estão apresentados na Tabela 6. Todavia, uma comparação entre os dados obtidos é difícil por causa da população, da amostragem e de reações inespecíficas no AAT em decorrência da presença de outras bactérias gram-negativas, o que resulta em falso-positivos no diagnóstico desta enfermidade nos animais (Tenório et al, 2008) A aproximação das taxas de prevalência para B. abortus em bovinos e ovinos deve-se, provavelmente, ao fato de que a ovinocultura não é tratada como atividade principal nas propriedades avaliadas. Em consequência disso, ocorre a exploração extensiva com a proximidade de outros animais como os bovinos, o manejo sanitário é inadequado e a assistência técnica é apenas periódica ou inexistente, o que contribui para a ocorrência da doença (Clementino et al, 2007).…”

A brucelose é uma enfermidade infecciosa, causada por bactérias do gênero Brucella spp. responsáveis por desordens reprodutivas nos animais, especialmente nos ruminantes. Este trabalho objetivou determinar a presença de anticorpos anti-Brucella ovis e anti-Brucella abortus em ovinos de 14 propriedades cadastradas na Associação de Ovinocultores do município de Colinas, Tocantins, Brasil. Para isso, amostras de soro de 450 ovinos foram analisadas por meio da aglutinação rápida em placa com Antígeno Acidificado e Tamponado (AAT) e, quando reagentes, foram realizados os testes de Aglutinação Lenta em Tubos (SAT) e 2-Mercaptoetanol (2-ME) para pesquisar cepas lisas (B. abortus). Para a pesquisa de cepas rugosas (B. ovis), foi realizada a Imunodifusão em Gel de Ágar (IDGA) e, quando reagente, foi realizada a Fixação de Complemento (FC). Das amostras analisadas, 142 (31,6%) reagiram ao teste de IDGA, dentre estas, apenas 4 (2,8%) foram confirmadas na FC. Ante o AAT, apenas 20 (4,4%) se mostraram positivas, das quais 14 (70%) foram confirmadas no SAT/2-ME. Os resultados obtidos nos testes de FC e SAT/2-ME e analisados pelo Teste de Fisher e OR demonstraram significância estatística entre a positividade e a faixa etária, sendo maior a chance de um animal em reprodução ser positivo para brucelose.

“…Questionnaires with information on age, sex and habits were applied prior to collection, in which all 213 participants agreed to answer a brief questionnaire applied before blood collection. The variables used in the elaboration of the questionnaire were based on the study by Tenório et al (2008). In addition, all participants signed the Free and Informed Consent Form (ICF).…”

The present study aimed to evaluate the seroprevalence of anti - Brucella abortus antibodies in Veterinary Medicine students at the Federal University of Mato Grosso (UFMT) - Sinop campus and Veterinary Physicians in the mid-north region of Mato Grosso, as well as the risk factors associated with its transmission. Blood samples were collected from the participants to assess the frequency of anti-Brucella abortus antibodies and sent to the Infectious Diseases Laboratory at UFMT Campus Sinop, where the samples were processed. The blood samples collected from indirect diagnostic methods, based on the detection of antibodies. This is an observational, cross-sectional, retrospective study, in which the results were evaluated through the analysis of the chi-square association by Fisher's exact test and for the identification of factors associated with the reagents for anti-Brucella abortus, it was carried out crude analysis using Poisson regression. Of the 213 volunteers, seven were tested for the Buffered Acidified Antigen (42.9%) and with a predominant range of age from 18 to 25 years (42.9%) %). The variable “Frequent Laboratory that diagnoses Brucellosis” (p = 0.028) was the only variable that remained significant after regression. It was concluded the lack of preparation and responsibility of some professionals when exercising the profession, not fulfilling the basics: protecting themselves and helping others to do the same, putting their health at risk and that of the population in general.

“…The prevalence of brucellosis in humans is directly linked to the number of infected animals, especially bovine species (Empresa Brasileira de Pesquisa Agropecuária {EMBRAPA], 2014). Professionals who work directly and frequently with animals or their carcasses are at risk of contracting the disease (Tenório et al, 2008;Langoni et al, 2009).…”

Brucellosis is a infectious zoonosis with important health and economic impacts, both for animal production and public health. We aimed to determine the prevalence of brucellosis in beef cattle in the microregions of Araguaína and Bico do Papagaio in northern Tocantins and to verify whether there are post-mortem changes suggestive of brucellosis in the carcasses. A total of 2,871 serum samples (2,203 males and 668 females) were collected in the municipality of Araguaína between October and November 2019, from 76 beef cattle herds in 25 municipalities in the north of Tocantins. The screening for buffered acidified plate antigen test (BAPA) and confirmation test for 2-mercaptoethanol (2-ME) were conducted as recommended by the Brazilian Ministry of Agriculture, Livestock, and Supply (MAPA). Of the samples, 37.31% were reactive in the BAPA test, and of these, 26.24% were confirmed for 2-ME. Thus, 9.79% (281) of the total evaluated samples tested positive for the presence of brucellosis. The prevalence in males and females was 6.45% (142) and 20.81% (139), respectively. Among the herds evaluated, 77.6% (59) had at least one individual test positive for brucellosis, and at least one herd tested positive in each of the 25 municipalities sampled. As this study evaluated animals in a slaughterhouse, the higher prevalence of positive females may have been related to the disposal of animals with reproductive problems. There was no significant difference in the prevalence of brucellosis in slaughter cattle between the microregions evaluated (p > 0.05). No animals were reagent for brucellosis in ante-mortem documentation, and no anatomopathological changes suggestive of brucellosis were observed during post-mortem inspection. The most frequent post-mortem findings were contamination (43.91%), blood aspiration (17.36%), and pulmonary emphysema (15.98%). Considering the official results of the monitoring programs of the state of Tocantins and previous studies, post-mortem macroscopic inspection of carcasses may not be enough to detect animals with this zoonosis, and it may be necessary to take measures to promote animal and public health.
