Abstract

RESUMO Foram colhidas amostras de placenta, ampola do ducto deferente e glândulas vesiculares de 80 ovinos abatidos no matadouro público de Patos, Estado da Paraíba, região Nordeste do Brasil para isolamento de Leptospira spp., bem como amostras de sangue para a pesquisa de anticorpos anti-Leptospira spp. O meio de Ellinghausen-McCullough-Johnson-Harris (EMJH) modificado com a adição de 10% de soro de coelho foi usado para o isolamento do agente e a técnica de soroaglutinação microscópica para a pesquisa sorológica. Os cultivos foram observados semanalmente por microscopia de campo escuro durante 16 semanas. Seis animais (7,5%) foram soropositivos na SAM, sendo o sorovar Autumnalis o mais frequente, com cinco soros reagentes, seguido pelo sorovar Icterohaemorragiae, com um soro reagente. Foi isolado micro-organismo morfologicamente similar a Leptospira spp. de uma amostra de ampola do ducto deferente e outra de placenta.ABSTRACT Placenta, ampulla of the deferent duct, and seminal vesicle samples were collected from 80 sheep slaughtered in the public slaughterhouse of Patos, Paraíba state, Northeastern region of Brazil, for isolation of Leptospira spp., and blood samples were taken from the same animals to check for the presence of anti-Leptospira spp. antibodies. Ellinghausen-McCullough-Johnson-Harris (EMJH) medium modified with the addition of 10% rabbit serum was used for the leptospira isolation, while the microscopic agglutination test (MAT) was used to check for the presence of antibodies. The cultures were observed weekly by dark field microscopy for 16 weeks. Six animals (7.5%) were seropositive by MAT, the serovar Autumnalis being the most frequent, with 5 reactant sera, followed by the serovar Icterohaemorragiae, with 1 reactant serum. A microorganism morphologically similar to Leptospira spp. was isolated from 1 ampulla of the deferent duct sample and 1 placenta sample.
