| Abstract: | In this study, pathological, serological and virological examinations were performed on 15 sheep from a flock of 250 sheep
and lambs that suffer from simultaneous naturally occurring BTV, PPRV and SPV outbreaks. SPV was diagnosed macroscopically
and histopathologically, BTV was diagnosed by ELISA, and PPRV was diagnosed pathologically and by ELISA. Clinically fever,
diarrhea, depression, polypnea, conjunctivitis, lacrimation, rhinitis, erosive stomatitis, edema of eyelids, photophobia,
cutaneous eruption with erythematous areas especially noticeable in wool-free parts of the body and axilla lesions evolving
into papules were observed. At necropsy, the most effected organs were lungs and gut. Subepicardial hemorrhages were also
commonly seen. While typical pox lesions were observed in some lambs, usually fibrinous pleuropneumonia was more prominent
lung lesion. SPV and PPRV lesions were seen at the histopathological examination of the lesioned tissues, BT lesions were
mild than SPV and PPRV microscopically. Serum and leukocyte samples of 15 animals were examined for PPRV and BTV by ELISA;
5 samples were positive for PPRV and 6 BTV, 4 were positive for both PPRV and BTV simultaneously. One hundred animals died,
most were lambs. Mortality rates were 100% in lambs and 80% in the herd. |
