First record of the avian acanthocephalan Polymorphus minutus (Polymorphidae, Acanthocephala) parasitizing a raccoon (Procyon lotor L.)

AbstractThe adult forms of Polymorphus minutus are the rather common helminths which are noted quite often in many water bird species, whereas the larvae are found in scuds, which are the intermediate host. The wide host spectrum of this acanthocephalan encompasses birds recruited from many different families and orders, which allows the species to be described as an unspecialized parasite (generalist). Cases in which the hosts for this parasite are not birds are very rare and relate only to Arctic foxes (Alopex lagopex) from Alaska. During this study on parasites of raccoons from the Czech Republic, 33 individuals were examined. In the intestines of two raccoons, 46 cystacanths were noted and identified as Polymorphus minutus. The research area from where the host material had been gathered can be described as bushy meadows placed on the outskirts of the river supplying the water complex of the fishponds. As this is a habitat for many wetland birds, the conditions are suitable for the existence and growth of this parasite. Examples of host barriers being overcome on the class level are rather rare for the parasites and all the identified acanthocephalan individuals are in the larval stage. Considering the context in which they were found, it seems that this record could be accidental. Since about thirteen species of acanthocephalan were noted in the raccoons, this first European record expands the list of the potential parasites for this host.
