Clinical investigations and treatment outcome in a European wildcat (Felis silvestris silvestris) infected by cardio-pulmonary nematodes.

Recently, feline cardio-pulmonary nematodes have attracted high scientific interest, as they are increasingly reported from various areas. Most of these parasites have similar transmission patterns and/or host reservoirs, thus they may affect domestic and wild felids living in sympatry. In the present study, a case of multiple cardio-pulmonary parasitism in co-infection with other parasites in a European wildcat is presented. The animal, found exhausted, was hospitalised for recovery and parasitological, haematological, clinical and imaging examinations were performed. The parasitological examinations revealed 4 cardio-pulmonary nematodes, i.e. Aelurostrongylus abstrusus, Troglostrongylus brevior, Eucoleus aerophilus, Angiostrongylus chabaudi, 3 intestinal parasites, i.e. Toxocara cati, ancylostomatids, Cystoisospora felis, 2 haemoparasites, i.e. Hepatozoon felis and elements morphologically compatible with small Babesia/Cytauxzoon spp., and Ixodes ricinus and Haemaphysalis erinacei ticks. Treatment with a spot-on formulation containing imidacloprid 10% and moxidectin 1% (Advocate® spot-on solution for cats, Bayer) was decided and follow-up faecal examinations were performed until the release of the animal. By the end of the hospitalisation, all metazoan endoparasites were no longer detectable in faecal examinations, with the exception of a low number of A. abstrusus larvae. Thus, the animal was released after a second treatment with the same product. This is the first description of an apparently successful treatment of multiple cardio-respiratory parasitosis in a naturally infected wildcat showing compatible clinical signs. The evidence that Advocate® may be effective against A. chabaudi could be useful for treating infected, hospitalised, wildcats and it is promising in the case A. chabaudi infection will spread to domestic cats in a near future.
