| Abstract | ||||
| study was conducted on 100 aged female buffaloes (average 7 years) slaughtered in the slaughter houses in Assiut Governorate, to clarify the parasitic and bacterial etiologic agents causing hepatic affections as well as their histopathological picture. Preslaughtering fecal samples by sedimentation technique revealed that 9 cases (9%) were infected with Fasciola gigantica and 2 cases (2%) with Fasciola hepatica. Mixed infection with two species were detecting in 9 cases (9%). Seventy six (76%) of the investigated animals showed gross hepatic lesion, where 20 cases (26.32%) were infected with adult Fasciola worm, 40 cases (52.63%) showed chronic hepatitis (26.32% multilobular cirrhosis; 19.73% biliary cirrhosis and 6.58% Glissonian cirrhosis). The last 16 cases (21.05%) revealed necrotic hepatic lesions. Bacteriological examination of these affected liver samples showed that 52 (68.4%) revealed positive bacterial growth on culture media either in the mixed form (83.17%) or in single form (16.83%). All fasciola infected livers showed positive bacterial isolation. Multilobular cirrhosis was the most form of chronic hepatitis showing bacterial isolation (35.64%) followed by biliary cirrhosis (13.86%). Staphylococcus spp. represented the most prevalent bacterial isolation (43.56%) followed by E. coli (21.78%) and Actinomyces pyogenes (15,84%). Streptococcus pyogenes and Enterobacter aerogenes were also recovered in proportion of 9.90 and 5.94%, respectively. It was concluded that livers of slaughtered aged female buffaloes showed a very high proportion of gross and histopathological lesions rather than they were considered as hazardous source of mixed different bacterial especially they showed positive Fasciola infection. | ||||
