snake inclusion body disease

thought due to a virus; observed in many boid snakes; characterized by heavy mortality after signs of CNS disease; inclusion bodies in most tissues, especially brain.

type A inclusion body

found in chromatically disrupted nuclei with margination of the chromatin fragments and the inclusion body is amorphous or granular and acid-staining; characteristic of cells infected with, for example, herpesvirus and adenovirus.

type B inclusion body

the nucleus is still well organized, there is no margination of chromatin and the inclusion bodies are well defined; seen in cells infected with, for example, distemper virus.
