**Common in Merino sheep and Angora goats
  −
**Ulceration around prepucial orifice with brown crust, and occasionally on vulva of ewes

**Bacteria hydrolyse urea to ammonia which causes mucosal irritation and ulceration

**High urine urea level, from high protein intake may predispose to condition

**High oestrogen levels in pastures also predisposes
  −
**Castration and heavy wool around the prepuce are risk factors

''Corynebacterium renale'' is a species of the ''[[Corynebacterium species - Overview|Corynebacterium]]'' genus. The species was previously classified as types I, II and III, but is now classified as ''C. renale'', ''C. pilosum'' and ''C. cystitidis''. 
 +
 
 +
It is found in the vulva, vagina and prepuce of normal cattle and can cause Bovine [[Lymphoreticular - bacterial diseases|pyelonephritis]], resulting in fever, anoexia, decreased milk production and enlarged ureters and kidneys palpated per rectum. It also causes [[Ulcerative balanoposthitis]] in ewes and [[Cystitis]].
 +
 
 +
''C. renale'' produces small, non-haemolytic colonies after 24 hours. Pigment is also produced after 48 hours.
