Abdul-Rahman LK, Salah Hussein Z., Lesions and bacteria isolated from livers of 3069 apparently normal sheep at slaughter, Onl J Vet Res., 22 (10):974-985, 2018. Authors report incidence of liver lesions detected in 3069 apparently healthy sheep over 8 months at abbatoirs in Iraq. We found abscesses in 1.35%, multi-necrotic foci in 0.94%, hydatid cysts in 0.71%, congestion in 0.13% and fatty change in 0.1%. Abscesses were more frequent (P < 0.01) than fatty change. Lesions were subjected to bacterial isolation and identification tests (Quinn et al. (2004). Bacteria (n=156) isolated were Staphylococcus aureus in 23.1%, E.coli 13.46%, Pseudomonas auroginosa 10.3%, Burkholderia cepacia 6.4%, Klebsiella pneumonia and Listeria grayi ~4.5%, Proteus vulgaris, Salmonella paratyphi and Staphylococcus klosii ~3.8%, Streptococcus pyogenes, Pseudomonas putrida and Enterobacter cloacae ~3.2%, Enterococcus fecalis, Proteus pennri, Aeromonos enchelia and Streptococcus pneumonia ~2.6%, Staphylococcus gallinarium and Corynebacterium pseudotuberclosis ~1.9%, Pseudomonas fluorescens ~1.3%, Shigella flexneri and Stenotrophomonas multiphilia ~0.64%. We isolated Staphylococcus aureus from 67% abscesses and 25% of necrotic foci, and E. coli, from 80.9% of hydatid cysts. Condemned livers were 1.35%, but incidence of abnormalities was low, probably due to the grazing nature of sheep in Iraq.
