Abstract

In order to investigate the prevalence and detection of etiological agents of pyelonephritis in Shahrekord
abattoir, 404 kidneys of slaughtered cattle (207 female and 197 male) were inspected. Kidney samples, which
had gross changes were obtained for histological examination. Urine and renal tissue samples were also
collected aseptically for microbiological examination. In histological examination pyelonephritis were
observed in 3 cases (0.74%), one of which occurred in a 7-year-old cow and the others in bulls less than 2-
year-old. In microbiological examination E. coli was isolated from urine and renal tissues in 2 cases and
Staphylococcus aureus isolated only from renal tissue in the other case.
