Pneumonyssoides caninum, the canine nasal mite, reported for the first time in a fox (Vulpes vulpes)

This is the first report describing the finding of the canine nasal mite, Pneumonyssoides caninum, in a silver fox (Vulpes vulpes). It is also the first time P. caninum has been found in a species other than the dog (Canis familiaris). A severely debilitated 10-month-old, male silver fox was euthanised due to suspected renal failure. During autopsy, a female mite matching the description of P. caninum was found in the nasal cavity of the fox. The finding of P. caninum in the fox suggests the existence of a new host, or at the very least a transient host. The fox's role in maintaining and/or propagating canine nasal mite infection needs to be explored.
