Parasitic helminths of black bear cubs (Ursus americanus) from Florida

Twenty-two Florida black bear (Ursus americanus floridanus) cubs (< or = 12 mo old) from Florida were examined for endoparasites between 1998 and 2003. Eleven species of helminths were found (8 nematodes, 2 trematodes, and 1 acanthocephalan). The most prevalent helminths were Ancylostoma caninum (64%), Macracanthorhynchus ingens (36%), Strongyloides sp. (27%), Baylisascaris transfuga (23%), and A. tubaeforme (14%). New host records include A. tubaeforme and Brachylaima virginianum. This is the first report of B. transfuga in black bears from Florida.
