This Bachelor thesis "Oribatida as intermediates host of tapeworms" is focused on the presence of tapeworm and other helminths occurring mainly in sheep and goats, monitoring prevalence and intensity of parasitic infection as well as significance of these endoparasites livestock for humans. These parasites pose a problem for people worldwide, mainly an economic terms. There are described the most common family of Anoplocephalidae tapeworm that are the most common parasites of reptiles, birds and mammals. Adult tapeworms are found only in the small intestine of the definitive host. This family of parasites is a species-rich group with cosmopolitan occurrence. These tapeworms are still a significant group for veterinary parasitology, because they cause many health problems for their hosts. The best known of this family is a sheep tapeworm (Moniezia expansa). The only tapeworm family Anoplocephalidae occurring humans are two kinds: Bertiella studeri and Bertiella mucronata, each with a different geographic distribution. Bertiella mucronata is found in South America and Cuba, Bertiella studeri occurs in Africa and Asia.
Tapeworms have allways two hosts: one intermediate host and a final host. As intermediate hosts there are mites of order oribatida (Oribatida) but bark lice (Psocoptera) or springtails (Collembola) can not be excluded aswell. The infection occurs by ingesting intermediate host infected by cysticercoidy. In order to reduce the prevalence of these parasites is necessary to conduct regular worming by using anthelmintics or plant extracts and regular removaling of excrements which are a source of eggs for the infectious intermediate host, in this case oribatid. In oribatida arises cystycercoid, which is infective for the definitive host (sheep). To eliminate tapeworms genus Moniezia of sheep (goat), it is necessary to eliminate these intermediate hosts. Which is a big problem.
