Infectious Stomatitis

Sometimes referred to as mouth rot, infectious stomatitis is a very common disorder that can affect pet lizards, snakes, and turtles. When a reptile is under stress, its immune system becomes weak and unable to keep the bacteria that are normally present in the mouth in check. The resulting infection leads to mouth rot.

Symptoms and Types

Signs of mouth rot can include:

• Loss of appetite
• Reddened oral tissues
• Thick pus and/or dead tissue within the mouth
• Drainage from the mouth and nose

If left untreated, infection can spread from the mouth into the rest of the digestive tract or into the lungs, causing pneumonia.

Causes

Improper temperature gradients or humidity levels within the terrarium can lead to a poorly functioning immune system and mouth rot. In some cases, an improper diet, or oral injuries that result from a reptile attempting to restrain live prey, rubbing against cage walls, or chewing on bedding material can also play a role.

Diagnosis

Mouth rot is generally diagnosed by observing the reptile's clinical symptoms, conducting a thorough physical exam on the animal, and reading over its medical history.
