title: Evidence of peste des petits ruminants virus (PPRV) infection in Sindh Ibex (Capra aegagrus blythi) in Pakistan as confirmed by detection of antigen and antibody.
abstract: An outbreak resulting in mortality in Sindh Ibex (Capra aegagrus blythi) was investigated. There was a history of about 36 deaths (both young and adult) during the period of 1 month. Disease appeared in a generalized form, affecting the respiratory and digestive systems. Major lesions were respiratory distress, pustules on and in the mouth, ocular-nasal discharges, and severe diarrhea. The most significant lesion was the oculonasal discharges and diarrhea. Deaths were mainly due to blindness, anorexia, diarrhea, and respiratory arrest. Both adult (mortality = 21) and young (mortality = 15) animals were affected with the disease. Peste des petits ruminants virus (PPRV) antigen was detected in the spleen, lung, lymph node, and swab samples by immunocapture enzyme-linked immunosorbent assay. Spleen and lung samples were also tested and found positive for the presence of F-gene of PPRV by polymerase chain reaction. Thirteen of 20 serum samples from nearby sheep and goats were found positive for antibodies to PPRV. The disease threatened the huge population of ibex in the wild life park, which was spread over a large area, but vaccination of the domestic population of sheep and goats in the surrounding villages appeared to control the disease.
