Intrahepatic larval nematode infection in the northern spring peeper, Pseudacris crucifer crucifer (Anura: Hylidae), in West Virginia.
Larval stages of an unknown nematode were observed encapsulated in the livers of spring peepers, Pseudacris crucifer crucifer (Weid-Neuweid), collected from a marsh in western West Virginia (USA) during the spring breeding seasons of 1993 and 1994. Prevalence and mean intensity of infection were 37% (30 of 82 animals) and 2.03 parasites per infected host, respectively. Capsules with white or darkly pigmented walls were observed in infected livers; the former containing viable larvae, and the latter enveloping larvae in various stages of degeneration.
