Ectoparasite infestations of red foxes (Vulpes vulpes) in Hungary.

A survey was carried out to investigate the ectoparasite infestations of 100 red foxes (Vulpes vulpes) in Hungary. The overall prevalence of flea and tick infestation was high (62 and 86% with the dominance of the anthropophil Pulex irritans and Ixodes ricinus), but the number of parasites was low to moderate. Felicola vulpis was not found in the present study, and the prevalence of Otodectes cynotis was only 2%. Based on prevalence (21%), mange lesion scores, and the negative correlation between lesion scores and condition of foxes, Sarcoptes infestation should be considered as the most important parasitosis of foxes in Hungary. Besides the ecological significance of these parasites, the high overall prevalence of mange and anthropophil flea and tick infestations of foxes and the appearance of these animals in the synanthropic environment as a result of the increasing population size, may result in the increasing incidence of flea, tick and accidental mite infestation of man and domestic animals, and may enhance the transmission rate of some vector-borne diseases.
