Abstract

The aim of this work was to evaluate the prevalence and intensity of the endoparasitic infection in the wild boars in the mountains of Pohronský Inovec. A wild boar (Sus scrofa L.) is a very adaptable animal, but its over preservation can often lead to the increased occurrence of the infectious and parasitic diseases. Wild boars are omnivores that live in groups, look for the wet and muddy places where good conditions can be found for development of various parasites. The young wild boars are particularly susceptible to many diseases. The experiment was carried out in the years 2014 and 2015. A total of 10 faecal samples were collected from the rectum and stored in the refrigerator. The laboratory diagnosis was performed within a day from the sample collection. The coprological examination was performed by the flotation method. The eggs of parasites were observed at the magnification of 40 x10. The prevalence of different types of parasites in the wild boars was as follows: Metastrongylus spp. 10 %, Hyostrongylus rubidus 10 %, Trichuris suis 40 %, Physocephalus spp 10 %, Ascaris suum 50 %, Strongyloides ransomi 10 % and Eimeria spp. 90 %. The intensity of infection was assessed on the basis of the number of parasite eggs in the samples. It can be stated that the intensity of infection was weak in most cases. Only in the case of Eimeria spp. there was determined the increased number of oocysts. The young individuals weighing up to 30 kg were the ones that were mostly infected.
