Aims: Aelurostrongylus abstrusus (Railliet, 1898) and Angiostrongylus chabaudi (Biocca, 1957) are important cardiopulmonary metastrongyloids in felids. This case report describes, for the first time, a natural and patent mixed infection caused by A. abstrusus and A. chabaudi in a European wildcat (Felis silvestris silvestris) from Bosnia and Herzegovina. Most important, this is a rare report of fatal parasitism in wildlife, involving a severe verminous bronchopneumonia and gastrointestinal nematode and cestode infection with Toxocara cati, Taenia taeniaeformis, Aonchotheca putorii, and Ancylostoma spp.
Results: Emphasis is set to detailed description of granulomatous, interstitial verminous bronchopneumonia, morphological description of A. abstrusus and A. chabaudi, and molecular confirmation of diagnosis by triplex PCR.
Conclusion: The data provided in this study contribute to the knowledge on the epizootiology and pathological effect of these neglected metastrongyloids in European wildcat.
