Abstract
Raccoons (P. lotor) typical of animals released by private hunting clubs in the Appalachian Mountains were examined for helminth parasites to evaluate the influence raccoon translocation might have on parasitic diseases. Results were compared with data from resident raccoons from characteristic release areas. Translocated raccoons harbored 19 helminth species that were exotic to resident animals. Most of these exotic parasites were trematodes (74%). An additional 19 spp. were found in translocated and resident raccoons and another 5 spp. were present only in residents. Three of the 19 exotic helminth parasites and 10 of the 19 enzootic species found in translocated raccoons are known to have some degree of pathogenicity to raccoons, other wildlife, domestic animals or man. At present, disease risks associated with the helminth parasites of these translocated raccoons were not considered alarmingly high; potential problems that could not be discounted were artificial intensification of undesirable enzootic parasites on release sites or expression of pathogenicity by exotic parasites presently considered nonsignificant. [Helminth species discussed belong to Cestoda, Trematoda, Nematoda and Acanthocephala.].
