Physaloptera sibirica in foxes and badgers from the Western Alps (Italy).
We investigated the presence of Physaloptera sibirica and its distribution as well as the association among the parasite, host (i.e. mange due to Sarcoptes scabiei) and environmental factors (i.e. altitudes) in foxes (Vulpes vulpes) and badgers (Meles meles) from the North-West of Italy. From 1996 to 2008 a total of 608 foxes, culled by hunters or road killed, and 39 road killed badgers were examined in order to investigate the presence of nematodes in the stomach. P. sibirica was found in 16 foxes (2.63%) and one badger (2.56%). As regards foxes' habitat type, prevalence was significantly higher (chi(2) = 16.36, p < or = 0.05) in mountain foxes (6.43%; 95%CI 3.25-11.22%) than those from hills (2.22%; 95%CI 0.46-6.36%) or irrigated plains (0.34%; 95%CI 0.01-1.90%). There were no significant differences between sex, age, months and years of the sampling. P. sibirica presence is significantly (chi(2) = 241.63, p > 0.000001) higher (73.33%; 95%CI 44.83-91.09%) in foxes with sarcoptic mange than foxes without mange (0.84%; 95%CI 0.21-1.84%). According to previous studies, in Southern Europe this parasite is associated with mountain areas, probably due to its intermediate hosts which require cold climate. Further studies are needed to evaluate the pathogenic role of P. sibirica in wildlife and its effects on host life history.
