| |
− | *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

| |
− | **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
