Photomicrographs of the plagiopatagium from a Little Brown Bat (Myotis lucifugus) captured live in Wyoming, U.S.A. (A) Adult nematodes (asterisks) are present in the dermis. They are filled with larval nematodes (arrowhead). The overlying epidermis is hyperplastic (arrow). H&E stain.

(A) Soft palate of a Cooper’s hawk (Accipiter cooperii). The submucosa is expanded by a myriad of epithelioid macrophages (arrow) surrounding multinucleated giant cells centered on a necrotic center (asterisk). H&E stain. Insert: Intrahistiocytic and extracellular acid-fast bacilli.
