Abstract:

Game animals can be the hosts of several parasitic agents including some which can pose a potential threat to public health, too. These are the so-called parasitozoonoses in which wild animals can act as reservoirs in maintaining and transmitting pathogens. In the last few years/decades studies have been made in several countries in the region to explore parasites, including neighbouring countries such as Serbia, Croatia, Romania and Ukraine. In Hungary the most frequently monitored area is the hunting area of Gemenc forest. Not only can our game animals play a role in human diseases but they can also infect pastures and be possible sources of our domestic animals’ infestations. Hunting dogs can also get infected during hunting.

The Szekszárd region is a hilly area in Southern Hungary located in Tolna County as part of the Transdanubian Hills. Its height is around 200 meters above sea level. The hunting area of the Szekszárd-Szálka hunting company is located in this territory and it is near the Gemenc hunting area. The size of the hunting territory is about 4,750 hectares. Wild animals that can be hunted are red deer (Cervus elaphus), fallow deer (Dama dama), roe deer (Capreolus capreolus) and boar (Sus scrofa). Since these two hunting areas are so close to each other we were curious about the similarities and differences regarding their parasitic fauna. One of our main interests was flukes so the examination of liver samples was of paramount importance.

During our research we collected samples between March 2016 and August 2018. In the course of the hunting season we had the opportunity to examine visceral samples, but outside of the season we could only evaluate faecal samples from the ground. Altogether we examined 48 liver samples and 63 faecal samples, and some lung- and rumen samples as well. Based on our findings we could make some conclusions in general about the parasitic infestation of the area. The following parasitic agents were detected: Trichostrongylida spp. (Cooperia sp., Nematodirus sp., Marshallagia sp.), Protostrongylida spp., Monezia benedeni, Elaphostrongylus cervi, Metastrongylus sp., Trichuris sp., Bunostomum sp., Dicrocoelium dendriticum, Fascioloides magna and it is likely that Fasciola hepatica is present as well. None of these parasites caused an infection with remarkably large intensity or extensity among the examined animals.
