| General Description |
- Localized inflammatory condition of the vent and cloaca seen mainly in
female birds and much less commonly in males. Has been recognized for many years in laying
hens, also in ducks.
- Feathers below the vent appear wet and bedraggled, being contaminated
with urates and inflammatory exudate. There is a characteristic unpleasant odour.
Initially swelling and reddening of the mucosa is seen, progressing to ulceration
affecting the vent and continuing a short distance into the cloaca; this may be covered
with a yellow diptheritic membrane.
(B11.4.w17, B13.19.w12, B34, B109) |
| Further Information |
- Usually affects only a small number of birds at one time.
- Risk of myiasis in summer.
- Scarring may result with associated reduction in the elasticity and
diameter of the cloaca, which may lead to problems with egg laying and even, in extreme
cases, defecation.
- Treatment: cleaning and local application of antibiotic - this is
not always effective (see: Topical
Medication of Birds).
- N.B. The condition has been recognized for many years
but the exact cause is unknown. In waterfowl, may be associated with lack of access to
water in which to defecate while swimming (see: Accommodation
Design for Birds - Temporary / Hospital Accommodation).
