  • C. renale, C. pilosum, C. cystitidis
  • Found in the vulva, vagina and prepuce of normal cattle
  • Bovine pyelonephritis
    • Stress of parturition and short urethra predisposes cows to urinary tract infection
    • Cystitis especially with C. cystitidis
    • Ascending infection from bladder through ureters causes pyelonephritis
    • Fever, anoexia, decreased milk production
    • Restlessness; kicking of abdomen indicate renal pain
    • Dysuria, arched back, bloody urine
    • Chronic infection causes extensive renal damage
    • Enlarged ureters and kidneys palpated per rectum
    • Culture from urine; protein and red blood cells in urine
    • Antibiotics e.g. penicillin for at least three weeks
  • Ulcerative balanoposthitis (pizzle rot):
    • 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
