 Burmese pythons generally show signs of central nervous system disease without manifestation of other clinical signs and regurgitation is seen only in boas.These are symptoms similar to those seen in specimens infected by "Chlamydia"–specifically "Chlamydophila psittaci", the so-called parrot's disease.Several snakes have been seen with proliferative pneumonia, while inclusions are commonly seen in the liver, kidney, and pancreas.
