The present study describes pathological findings in 25 cases of Peste des Petits Ruminants (PPR) infection. Out of 462 goats carcass examination, in which 262 cases were from slaughtered animals and 200 cases were from fallen animals. On post mortem examination, pathological findings included erosive ulcerative stomatitis, severe haemorrhagic enteritis along with enlarged mesenteric lymph node. The large intestine of affected animals showed pathognomonic haemorrhages like zebra striping (zebra marking) and ecchymotic haemorrhages in abomasum. Histopathological lesions were characterized by syncytial cell formation, infiltration of mononuclear cells with eosinophilic intranuclear inclusions in alveolar macrophages of lungs section. Gross and histopathological lesions were suggestive for PPR infection, which was further confirmed from the specialized PPR laboratory in Mukteshwar (Uttarakhand) Regional Station of ICAR, IVRI using s-ELISA.
