Raccoons infected in the laboratory allowed a previously unidentified cystacanth from woodroaches, Parcoblatta pennsylvanica, and various colubrid and viperid snakes in Louisiana to be identified as Macracanthorhynchus ingens. The epizootiology of M. ingens in Louisiana was studied by feeding trials devised to illustrate development and possible pathways of transmission. The woodroach was documented as a naturally-occurring, first intermediate host. Cystacanths of M. ingens from woodroaches were capable of establishing viscerally in snakes or developing to adulthood in raccoon intestines. Those from snakes were capable of subsequently maturing in the gut of raccoons. Possible transmission pathways have been established from woodroach to raccoon and from woodroach to snake to raccoon. Investigation of feeding habits and habitat preference of the animals involved suggests that both pathways function in nature.
