Avaliação genética das vacinas contra a brucelose bovina comercializadas no Brasil

Abstract: A prevenção contra infecções causadas por Brucella abortus em bovinos é realizada por meio da administração das amostras vacinais B19 e RB51. Existem relatos de que estas vacinas podem causar aborto em fêmeas vacinadas. Portanto, toda a ocorrência de aborto em animais vacinados merece um estudo aprofundado sobre a causa. No Brasil, não há registro sobre a origem das amostras B19 e RB51 utilizadas na produção das vacinas comerciais. Assim, um estudo para verificar possíveis mutações em relação às amostras refer… Show more

“…However, they showed considerable seropositivity, which was justified by the expectation of the 80% protection that the vaccine gives to herds. The RB51 vaccine sample has been alternatively used in several countries in animals aged over 8 months old or as a booster of B19, demonstrating greater resistance to infection and reducing abortion rates (YAZDI et al, 2009;BASTOS et al, 2012). However, it is still not used in the state.…”
