Influence of anthelmintic baits on the occurrence of causative agents of helminthozoonoses in red foxes (Vulpes vulpes)
2006
Red fox (Vulpes vulpes) presents major wildlife reservoir of parasitozoonoses, transmissible to humans and domestic animals. The study was aimed to find out the effect of anthelmintic baits on the occurrence of Echinococcus multilocularis and other intestinal helminths in red foxes. In two bait areas (B1 and B2) 20 baits per km2 were distributed monthly between August 2004 and April 2005. Fox fecal samples were collected in both bait areas and two control areas (C1 and C2) between August 2004 and August 2005. In bait area B1 the decrease of parasite species number, decrease of their prevalence and prevalence of E. multilocularis was observed. No significant decline was observed in bait area B2, probably due to consumption of baits by wild boars. Bait distribution represents the possibility of reduction of environmental contamination with parasites and their propagation stages. Especially on the periphery of towns and villages and in recreational areas it seems to be suitable way of human health protection.
