Tissue from a gull (Larus sp) from Wisconsin. (A) Diffusely the pericardium (star) is greatly expanded by fibrin, edema and necrotic debris (H&E). (B) Lymphoplasmacytic myositis (arrows) creating linear lesions along fascial planes of the pectoral skeletal muscle (H&E).

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.

Gross photographs from a Cooper’s hawk (Accipiter cooperii). (A) Air sac overlying the lung and liver have multiple yellow to green, irregular nodules (arrows). (B) Liver (asterisk) has multiple 1 mm, round to irregular, tan nodules in addition to innumerable miliary foci.

(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.
