Keywords:Kidney, sheep, bacteria, pathological
This study was carried out to determine the prevalence and type of renal lesions in sheep that were slaughtered at Fallujah abattoir. A total number of 100 clinically normal sheep of different sex and age randomly selected, renal samples were taken for , bacteriological, macro and micro study. One hundred swabs were taken from cortex and medulla were cultured on blood, nutrient, and MacConkey agars, then biochemical tests were done for identification of these bacteria. Bacteriological examination of kidney revealed that (65%) of samples show positive results in bacterial isolation including (15%) Bacillus, (10%) Escherichia coli, (11%) Klebsiella, (18%) Staphylococcus, (8%) streptococcus, (3%) Corynebacterium spp., (3%) pseudomonas aeruginosa, (1%) Salmonella and (1%) Proteus. Pathological study showed that 24 (24%) and 38 (38%) gave positive results in macroscopic and microscopic lesions respectively, the results of gross pathology were renal hemorrhage 8%, pale kidneys 4%, enlarged kidneys 4% white spotted kidneys 3%, renal fibrosis 2% , pigmented kidney 2% and renal cyst 1%. Meanwhile the microscopic lesion were nephritis 24 % (interstitial nephritis 9%, glomerulonephritis 6%, tubular nephritis 5%, and pyelonephritis 4%) nephrosis 5%, kidney fibrosis 3%, infarcted kidneys (2%), amyloidosis 2% hemosiderosis 2%. From the presented study, it was concluded that most kidneys are infected with many gram negative and gram positive bacteria and many kidney problems such as renal hemorrhage and interstitial nephritis are the most common renal lesions in sheep.
