Bacteriological and biochemical examination of liver lesions of slaughtered goats (Capra hircus) in and around Guwahati, Assam

Abstract

The present investigation was conducted to study the bacteriological and biochemical examination of the pathological lesions found in the livers of goats in and around Guwahati. Liver samples were collected from goats slaughtered for human consumption from different slaughter places and meat shops. For this purpose, 1,031 livers of slaughtered goats were examined. A total of 167 (16.19 per cent) goat livers were found to be affected with various pathological conditions on gross and histopathological examination. Out of these livers, thirty seven (37) liver samples were found with the presence of abscess and necrotic lesions which were then subjected to bacterial isolation. Bacterial identification was done on the basis of colony morphology, cultural characteristics and biochemical tests. The bacteria isolated from hepatic abscess and necrosis were Staphylococcus aureus, Streptococcus spp., E. coli, Salmonella spp. and mixed culture of Staphylococcus, Streptococcus, E. coli and E. coli, Salmonella spp., Staphylococcus aureus. Gram positive cocci were found to be dominant among the isolates. Serum enzymes like ALT, LDH and GGT were estimated and statistically compared between goats with liver lesions and without liver lesions. These Serum enzymes were found to be significantly higher in goats with liver lesions.
