Filarial dermatitis in a striped skunk.

A striped skunk (Mephitis mephitis) from Kansas (USA) with severe diffuse dermatitis characterized by extensive alopecic areas, thickened skin, and multiple, scattered cutaneous abscesses on the dorsal aspect of the head, neck, and trunk was submitted for diagnostic evaluation. More than 50 nematodes identified as Filaria taxideae were found in the dorsal subcutaneous tissue. Histologic examination of the skin revealed multifocal pyogranulomatous inflammation with intralesional larvated nematode eggs, moderate orthokeratotic hyperkeratosis, and mild acanthosis. The lesions resemble those reported from badgers (Taxidea taxus) and a lesser panda (Ailurus fulgens) with dermatitis caused by Filaria taxideae. Although F. taxideae has been previously collected from skunks, this is the first report of filarid dermatitis caused by this nematode in a striped skunk.
