title: Visceral lesions in racoons naturally infected with Heterobilharzia americana.
abstract: Three free-ranging raccoons caught in southeastern Florida were found to be infected by Heterobilharzia americana. The livers were firm with rough surfaces and stellate patterns of periportal fibrosis. The portal tracts had excessive mature fibrous connective tissue and occasional ovum and necrotic fluke granulomas. There were also ovum granulomas with concomitant lesions in small and large intestine, pancreas, and lung. Numerous other parasites were seen.
