Purpose:
Breeding of wild boars is a significant part of the hunting economy; however, hogs are associated with zoonotic infection. This study assessed the prevalence and degree of parasitic infections that exist in wild boars from two hunting grounds in the Autonomous Province of Vojvodina, Republic of Serbia.
Methods:
Parasitological examinations were conducted from 2016 to 2019. In total 220 fecal samples and 13 lungs were collected from wild boars in two hunting grounds (an open and a closed habitat) on the territory of Vojvodina (Serbia). Assessment of the prevalence and degree of the detected endoparasitosis involved a semi-quantitative fecal egg count method.
Results:
The presence of protozoa-Eimeria spp./Isospora spp. (76.38%; 32.26%) and Balantidium coli (7.08%), nematodes-Ascaris suum (29.03%), Trichuris suis (31.49%; 19.35%), Hyostrongylus rubidus/Oesophagostomum spp. (55.12%; 48.39%), Metastrongylus pudendotectus (66.14%; 21.51%), Gnathostoma hispidum (3.94%; 2.15%) and Macracanthorhynchus hirudinaceus (9.45%; 7.53%) and trematodes-Fasciola hepatica (5.51%; 4.30%) and Dicrocoelium dendriticum (0.78%; 2.30%) were detected as single or mixed infections, via qualitative coprological examination. The total prevalence of the endoparasitosis was 92.91% in hunting ground I (closed habitat) and 73.12% in hunting ground II (open habitat). The most prevalent infection in hunting ground I was coccidiosis (76.38%), and hyostrongylosis/oesophagostomosis (48.39%) in hunting ground II. Adult forms of M. pudendotectus were identified in the lungs of 13 wild hogs with mild to severe bronchopneumonia from hunting ground II.
Conclusions:
The semi-quantitative fecal egg count method demonstrated clinical and parasitological significance and revealed the risks associated with zoonotic infections in this game species population. Therefore, monitoring the etiology and epizootiology of parasitic infections in wild boars is essential for creating health care programs in hunting ground areas and planning control strategies that protect both the hunting economy and public health.
