Angiostrongylus vasorum in golden jackals (Canis aureus) and red foxes (Vulpes vulpes) from Northern Bosnia and Herzegovina.

Abstract

In this study, we conducted post-mortem examinations of golden jackals (Canis aureus) and red foxes (Vulpes vulpes) from the northern region of the Republic of Srpska (Bosnia and Herzegovina) to detect the presence of Angiostrongylus vasorum. An epidemiological survey was conducted in the densest golden jackal population in the country. Over two time intervals, we examined a total of 30 jackals and 16 foxes. The presence of A. vasorum was confirmed in two jackals (6.6%) and one fox (6.25%). These findings strongly suggest that the spread of A. vasorum can be facilitated by the active expansion and migration of golden jackals in Southeastern Europe. The morphological and molecular detection of A. vasorum in jackals and foxes confirmed its presence and active circulation in wildlife, while the phylogenetic analysis of the ITS-2 gene indicated a low sequence distance from European isolates.
