Rabbit Moist Dermatitis Study Guide
Overview and Clinical Importance
Moist dermatitis (also known as wet dewlap, slobbers, or chin scald) is a common bacterial skin condition in rabbits caused by chronic exposure of skin to moisture. This condition most frequently affects the dewlap, chin, and ventral neck region but can also occur perianally with urine scald. Understanding moist dermatitis is essential for the NAVLE as it represents a multisystem disorder involving dermatology, dentistry, husbandry, and infectious disease principles.
Pathophysiology
Moist dermatitis develops when rabbit skin is chronically exposed to moisture, leading to maceration of the skin and disruption of the normal protective barrier. The pathophysiologic sequence involves:
- Chronic moisture exposure causes skin softening and breakdown
- Compromised skin barrier allows bacterial colonization
- Bacterial proliferation leads to inflammation and infection
- Progressive tissue damage results in ulceration
- Severe cases may progress to cellulitis or abscess formation
Common Bacterial Pathogens
The most frequently isolated bacteria include:
