Scale rot (necrotic dermatitis) in reptiles

Overview

Scale rot, or necrotic dermatitis, is a common skin condition affecting reptiles such as lizards, snakes, and turtles. It occurs when bacteria infect the skin, leading to lesions and potential systemic infection if untreated.

Causes

Scale rot is primarily caused by poor husbandry conditions, including unsanitary living environments, high humidity, and inadequate temperature control. These conditions facilitate bacterial growth, leading to infection.
