Abstract
Peste des petits ruminants (PPR) affected goat kids showed clinical signs of pyrexia, congested mucous membrane, profuse
diarrhea, bilateral mucopurulent nasal discharge, erosive stomatitis and glossitis with halitosis. On necropsy, erosions to ulcer on
the nasal openings, frothy exudate in the tracheal lumen with severe consolidation and red hepatisation of cranial and diaphragmatic
lobes were observed. Histopathologically, hyperkeratosis with irregular breakage in the nasal epithelium of nasal opening
and tracheitis with deciliation, infiltration of lamina propria by mononuclear cells and submucosal hemorrhages and congestion
were recorded. Lungs showed severe acute bronchointerstitial pneumonia with severe neutrophilic infiltration,collapsed bronchi
and bronchiolar lumen filled with debris of desquamated bronchial epithelial cells, degenerated and non-degenerated neutrophils,
syncytial formation with multinucleated cells containing intranuclear and intracytoplasmic eosinophilic inclusion bodies. Reverse
transcriptase PCR and sequence analyses of partial N gene confirmed the etiological agent as PPR virus lineage IV.
