The study includes isolation and identification of Corynebacterium renale from urine of cow apparently suffering from urinary tract infection.

C.

renale represent highest isolate 49.

99% followed by Corynebacterium pyogenes 24.24% from the total number of Corynebacterium 74.23%.

on the other hand Staphylococcus saprophyticus also isolated from urine samples 25.75%.

Since C.

renale was isolated at highest rate we studied its pathogenesis via inoculation of isolate intraperitoneally into white Swiss mice.

Results showed that C.

renale type I has ability to produce kidney damage after 48 hr.

post inoculation revealed embolic glomeruler nephritis with less number of C.

renale, also there is infiltration of polymorphnuclear inflammatory cell and nephrosis, in addition to vacular degeneration, coagulative necrosis with blood vessel congestion in liver tissue.
