Photomicrographs from Wild Turkeys (Meleagris gallopavo) found dead in Wisconsin, USA.  (A) In the liver, hepatocytes were replaced by macrophages, lymphocytes, and plasma cells (lower left) with occasional multinucleated giant cells (arrows). H&E stain.  (B) The cecum contains a fibrinonecrotic membrane effacing the mucosa (arrow). H&E stain. (C) Within the necrotic debris in the cecum, there are extracellular and intracellular protozoal trophozoites (histomonads) surrounded by a clear space (arrows). A few multinucleated giant cells are present (arrowhead). H&E stain.
