Lesions and bacteria isolated from livers of 3096clinically normal sheep at slaughter.

摘要

In Iraq, inthe recent past, due to constant military conflict and to avoid statutorycondemnations butchers themselves slaughtered sheep. Authors report incidence ofliver lesions detected in 3069 apparently healthy sheep over 8 months at abattoirs inIraq. We found abscesses in 1.35%, multi-necrotic foci in 0.94%, hydatid cysts in0.71%, 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 andidentification tests (Quinn et al. (2004). Bacteria (n=156) isolated wereStaphylococcus aureus in 23.1%, E.coli 13.46%, Pseudomonas auroginosa 10.3%,Burkholderia cepacia 6.4%, Klebsiella pneumonia and Listeria grayi ~4.5%, Proteusvulgaris, Salmonella paratyphi and Staphylococcus klosii ~3.8%, Streptococcuspyogenes, Pseudomonas putrida and Enterobacter cloacae ~3.2%, Enterococcusfecalis, 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 in 67% abscesses and 25% necrotic foci,and E. coli from 80.9% of hydatid cysts. Condemned livers accounted for 1.35%, butincidence of abnormalities was low probably due to the grazing nature of sheep inIraq.
