Abstract:
The study was conducted to elucidate the pathological findings of inflammatory conditions i.e. pericarditis, myocarditis and endocarditis related to heart of sheep (Ovis aries). Cardiovascular system was examined with total 587 samples, irrespective of age, breed and sex. Out of these, suspected 147 specimens of heart with pathological abnormalities were processed for histopathological examination. Inflammatory conditions i.e. myocarditis, endocarditis and pericarditis were recorded in 11 cases with occurrence of 7.48 per cent. In cases of pericarditis macroscopically heart showed discoloration and congested blood vessels. On microscopic examination the pericardium showed infiltration of polymorphonuclear and mononuclear cells. In cases of myocarditis, macroscopically red discoloured areas on the ventricles were seen. Microscopically, severe infiltration of polymorphonuclear and mononuclear cells was seen in myocardium. In cases of endocarditis macroscopically haemorrhagic areas were seen on endocardial layer of ventricles. On microscopic examination, infiltration of mononuclear and polymorphonuclear cells was seen in endocardium.
