“…Dos equinos testados neste estudo, nenhum foi positivo nos testes. Santos et al, (2016), encontraram uma baixa frequência (0,26%) de equinos positivos dentre 767 animais do Paraná, Santa Catarina e Rio Grande do Sul. Em Minas Gerais, foi encontrada prevalência de brucelose em equinos de 1,37% para animais e 4,28% para rebanhos (Junqueira, et al, 2015).…”

“…Na Paraíba, 0,8% dentre 123 cavalos de trabalho testados foram positivos (Antunes, et al, 2013). É possível inferir, que em regiões em que a brucelose bovina é endêmica, pode haver resposta sorológica em equinos, devido ao compartilhamento de pastagens, fontes e água e contato direto (Junqueira, et al, 2015;Santos et al, 2016).…”

“…Apesar da dificuldade de estabelecer a transmissão da doença na espécie, não se pode desprezar o potencial de transmissão da infecção para outros animais e para humanos, o que caracteriza um papel importante também na saúde pública (Corbel, 2006). Além disso, em estados como Santa Catarina, cuja prevalência da doença em bovinos é baixa, esse potencial deve ser cuidadosamente controlado para que não interfira na erradicação da doença (Santos, et al, 2016).…”

A brucelose é uma das mais importantes e negligenciadas doenças zoonóticas. Objetivou-se com o estudo conhecer a epidemiologia, as perdas econômicas e os fatores de risco da brucelose em bovinos, equinos, cães e humanos no município de Flor do Sertão – Santa Catarina. Examinou-se para Brucella abortus, entre 2017 e 2018, 2.750 bovinos, de 131 propriedades; 20 equinos e 29 cães. Os testes sorológicos de triagem seguidos de confirmatório realizados foram o AAT e 2 ME/SAT. Para casos de brucelose humana, a secretaria de saúde do município concedeu 206 resultados sorológicos referentes ao mesmo período de estudo dos bovinos. Foram calculadas prevalências da doença para as populações e utilizado o teste da árvore de decisão, pelo programa estatístico Weka®, para estabelecer associação entre fatores de risco e a positividade de rebanhos. O teste de Spearman (GraphPad Prism®) foi utilizado para estabelecer correlação entre casos humanos e bovinos. 45,5% da população de bovinos do município foi testada, demonstrando prevalência de brucelose de 0,29%. As perdas econômicas anuais foram de R$ 14.747,92. Foram positivos 5,33% dos humanos testados. Os fatores associados com a positividade para a doença baseiam-se no consumo produtos lácteos sem tratamento térmico, e prevalência de brucelose acima de zero. Observou-se que em Flor do Sertão – SC, a prevalência de brucelose em bovinos é baixa, porém, elevada para focos. No entanto, a prevalência da doença em humanos foi elevada, sendo superior a prevalência animal, possivelmente decorrente dos fatores de risco associados a positividade da doença, como o consumo de lácteos crus.

“…In Rio Grande do Sul there were also high seropositivity of 27.3% (6/22) in slaughterhouse capybaras [37], 38.75% in bovines (527/1360) [14] and 90.36% (553/612) in equines [35]. Dogs in the rural area of the municipality of Pelotas showed seropositivity (with a cut off 1:50) at even lower frequency than in this study, of 2.66% (13/489) [16].…”

Frequency of anti-Leptospira spp. antibodies in dogs and wild small mammals from rural properties and conservation units in southern Brazil

Leptospirosis is a disease of worldwide distribution that affects man and several animal species. Domestic and wild animals can behave as reservoirs of the agent. The aim of this study was to evaluate the frequency of anti-Leptospira spp. antibodies in dogs and wild small mammals from rural properties and conservation units of three municipalities of Rio Grande do Sul State, Brazil. Sera were collected from 192 domestic dogs and 132 small mammals, namely rodents of the Cricetidae and Caviidae families and marsupials of the Didelphidae family. The study used Microscopic Agglutination Test (MAT) against 23 serovars of Leptospira spp. Overall, 9.90% (19/192) dogs, and 1.51% (2/132) small mammals were seropositive. Leptospira interrogans serovar Australis was the most frequent serovar in dogs and antibodies against L. interrogans serovar Pomona were detected in a dog and a small mammal belonging to the same municipality. We conclude that in the regions studied the frequency of seropositivity in dogs is low, and leptospires do not seem to be circulating in small mammals, yet, further research is necessary to assess the real role that these animals may have for leptospirosis in the studied areas. This is the first serological survey in small mammals, including wild rodents, in the area that encompasses conservation units of great importance to Rio Grande do Sul state.

“…According to the National Center for Zoonotic Diseases (NCZD), five of the most prevalent zoonotic diseases in Mongolia include tickborne rickettsiosis, anthrax, rabies, tick-borne encephalitis, and brucellosis. Worldwide, horses have been found to be carriers for all five of these diseases (Rushton et al 2013, Turner et al 1999, Merini et al 2010, Moraes Filho et al 2009, Santos et al 2016, Tahamtan et al 2010) and have been found specifically to carry rabies, anthrax, and brucellosis in Mongolia (Odontsetseg et al 2009, Zolzaya et al 2014, Odontsetseg et al 2007. A similar study rating the risks of zoonotic disease in Mongolia to humans and livestock found brucellosis, rabies, and anthrax to be three of the top four most important diseases, with the fourth being echinococcosis (McFadden et al 2016).…”

Potential risk factors for zoonotic disease transmission among Mongolian herder households caring for horses and camels

Mongolia has more than ten times as many livestock as people. Herders are dependent on their livestock for their livelihood, and seasonal movement is driven by the livestock's grazing needs. The daily, seasonal interactions between Mongolian herders and their livestock put herders at risk for several zoonotic diseases. The goals of this pilot study were to describe potential risk factors for zoonotic disease transmission and note how they differed for herder families between provinces (aimags). As part of a larger study, a household survey was administered to 131 households in Arkhangai, Uvurkhangai, and Umnugobi provinces aimags during 2016 and 2017. The study was limited due to its self-reported survey data and its convenience sample design. We did not capture specific disease data. All households cared for either or both horses (Equus ferus caballus) and Bactrian camels (Camelus bactrianus). All households had a cell phone and access to a power source, primarily solar panels (93.1%). Families reported spending on average 3.9 h a day with their horses or camels. As all five of the most prevalent zoonotic pathogens in Mongolia have horses as reservoirs, and three of the five may also reservoir in Bactrian camels, herder families with horses or camels potentially experience daily risks from zoonotic diseases. Our pilot study data demonstrated that zoonotic disease transmission could occur through a number of ways, such as directly from contact with livestock or manure or from contaminated food, milk, or water. Sixty-four percent of herder households reported using dried manure for fuel. Unprocessed river water was often the primary source (52.7%) of drinking water, which is potentially contaminated with manure-borne pathogens. Fuel and water sources varied by herder household location. A unifying finding was the ubiquity of cellphones in all surveyed herder households, providing a potentially efficient method for public health communication.
