Author(s):
Pavan CK, Ramesh PT, Sundar NS and Veere Gowda BM
Abstract:
Sheep that died due to respiratory illness were subjected to postmortem examination(n=61) and lung specimens were collected for isolation, PCR work and histopathology A total of 21 lung samples which were found positive for Manneheimia haemolytica through PCR were also subjected to study of gross pathology and histopatholgy. Observed necropsy lesions were viz., consolidation of cranial apical lobe, pleural adhesions, sero sanguinous fluid in thoracic cavity, fibrinous pneumonia, cut section showing muco- purulent exudates and froth in the trachea with congestion.
Lung histopathology revealed edema, haemorrhages, congestion and infiltration of PMN cells in alveoli. Also observed deposition of fibrin strands and haemosiderin pigment in interstitial tissue.
