Ninety two piglet carcasses showing respiratory lesion presented to the Department of Veterinary Pathology, College of Veterinary and Animal Sciences, Mannuthy, Thrissur for necropsy were selected for detailed pathological and bacteriological studies. Five lung samples were found to be positive for Salmonella choleraesuis infection based on culture, morphology, biochemical tests and fliC gene based PCR. Gross lesions of Salmonella infected piglets revealed severe congestion, oedema, areas of consolidation, extensive haemorrhage and emphysema in lungs, frothy exudates in tracheal lumen and enlargement and congestion of the bronchial lymph nodes. Microscopically oedema fluid, infiltration of inflammatory cells in the interstitium and haemorrhages were the prominent changes in lungs characteristic of interstitial pneumonia were noticed. Bronchial lymph nodes showed lymphoid depletion and haemorrhages. This study established the prevalence, pathology, molecular detection S. choleraesuis in respiratory infection in the pig population in Thrissur.
