Cowdry bodies

Cowdry bodies are eosinophilic or basophilic^[1] nuclear inclusions composed of nucleic acid and protein seen in cells infected with Herpes simplex virus, Varicella-zoster virus, and Cytomegalovirus. They are named after Edmund Cowdry.

There are two types of intranuclear Cowdry bodies:

Type A (as seen in herpes simplex and VZV) ^[2]
Type B (as seen in infection with poliovirus and CMV), though it may seem that this is an antiquated and perhaps illusory type.^[3]

Light microscopy is used for detection of Cowdry bodies.
