Multietiological abortion induced by Brucella melitensis and Chlamydophila abortus in a sheep fetus

Abstract

In this case, multietiological abortion due to Brucella melitensis (B. melitensis) and Chlamydophila abortus (C. abortus) agents was defined in a sheep abortion. An aborted sheep fetus submitted to Konya Veterinary Control Institute (KVCI) from a sheep farm in Nigde province in Brucella spp. presence was determined by bacterial isolation method and confirmed by slide agglutination test with monospecific A and M sera. C. abortus was detected by real time PCR and immunohistochemistry (IHC) methods. In histopathological examinations, in the lung; hyperemia, hemorrhage and bronchopneumonia, In the heart; in the placenta with degeneration and necrosis of heart muscle cells; hyperemia, hemorrhage, edema, necrosis and mononuclear cell infiltrations were observed. In this study, it was emphasized that in the fight against sheep abortions, multi-etiological abortions involving more than one factor should be taken into consideration, as well as an etiological agent, and it would be appropriate to use multidisciplinary diagnostic methods to determine the abortion factors, thus contributing to the prevention of abortions, which is still an important problem in sheep breeding.
