Respiratory Infections in Reptiles

2 min read



Pneumonia and most other respiratory infections in reptiles are caused by bacteria. In some cases, however, viruses, fungal infections, or parasites may be to blame. Treatment varies depending on the microorganism involved, so take your pet to an experienced reptile veterinarian for diagnosis if it begins to exhibit signs of a respiratory infection.


Symptoms and Types


Typical symptoms of a respiratory infection include:


  • Difficulty breathing
  • Mouth held open while breathing
  • Unusual wheezes, crackles, or other sounds while breathing
  • Discharge from the mouth and/or nose
  • Lethargy
  • Loss of appetite
  • Weight loss


In severe or untreated cases, bacteria can enter the bloodstream and cause a potentially fatal condition called septicemia.




Respiratory infections are very common when reptiles are kept in dirty environments or do not have access to proper temperature gradients and/or humidity levels. Poor diet, parasitism, illness, and in turtles, a lack of vitamin A in the diet, can also play a role.




A veterinarian will tentatively diagnose a respiratory infection based on an animal’s history, clinical signs, and physical exam. Determining the severity of a pet’s condition, which types of microorganisms are involved, and the appropriate treatment regimen may require blood work, X-rays, fecal exams, and bacterial sample taken from the reptile's respiratory tract.
