The first occurrence of anthelmintic resistance in strongylid nematodes of sheep and horses in Czech Republic

Endoparasitoses of fallow deer (Dama dama) in game-park in South Moravia (Czech Republic)

“…According to the knowledge recorded in literature, parasitoses under our conditions can have intensive impact on health status and class of ungulate game and thereby on the results of hunting management (Chroust & Vitula, 2005). Venison, as well as domesticated ruminants, has various endo-and ectoparasites.…”

“…On the contrary to wild ungulate game, animals kept in game-parks are more susceptible to parasite infection as a result of huge density of animals living in restricted area and the intensive breeding practices (Barth & Matzke, 1984;Rehbein & Bionschek, 1995;Rehbein et al, 2001). In former times, according to Chroust (2001), parasitoses were the main cause of losses in ungulate game. This experience was confirmed by the results of highly detailed and wide dissections and coprologic exams that were carried out in the beginning of the 80's.…”

“…Keepers usually took broad care of animals. They even considered the parasitic aspect, because especially parasitoses can be limiting factor of game class and through that even of economical results of management ....... (Chroust, 2001). Deer in common, and fallow deer as well, can suffer from several tens of endoparasite species (GIN and LW) (Kotrlá et al, 1984;Balicka-Ramisz et al, 2005;Vengušt & Bidovec, 2003), with different prevalence and intensity of invasion (Ambrosi et al, 1993;Santin-Duran et al, 2004;Drozdz et al, 1997).…”

“…Values of prevalence and intensity themselves, however, don't have to predicate the health status of animals (Horning, 1975). Furthermore, this aspect may be influenced by presence of other deer species in the area (Santin-Duran et al, 2004;Horning, 1975), subclinical infection of hosts (Gunn & Irvine, 2003;Langrová et al, 2008) and of course breeding management and eventual drug treatment (Chroust, 2001;Chroust & Vitula, 2005). Aim of this work was to detect fluctuation of prevalence and intensity of parasitocenoses in fallow deer during period of joint efforts of breeder and parasitologist in order to help the animals regain health.…”

Detection of benzimidazole resistance in gastrointestinal nematode parasites of sheep in the Czech Republic

“…This issue appears to be relevant all over the world: there are studies that confirm the rapid evolution and spread of resistant parasites (Besier and Love, 2003;Kaminsky, 2003;Ancheta et al, 2004). Helminths resistant to commonly used anthelmintics have been identified in the Czech Republic (Chroust et al, 1998;Chroust, 2000). Studies conducted in Slovakia, meanwhile, demonstrated that also in this country there are sheep farms with the occurrence of gastrointestinal nematodes resistant to benzimidazoles drugs (Praslicka et al, 1994).…”
