Trichuris nematodes in wild ruminants
Páclík, David ; Langrová, Iva (advisor) ; Nechybová, Stanislava (referee)
The parasite Trichuris species is widespread in wild ruminants in the country. In ruminants there are several species of parasite. In ruminants were species Trichuris discolor, Trichuris capreoli, Trichuris globulosa, Trichuris ovis, Trichuris skrjabini. Parasites of the genus can infect wild ruminants and economically ruminants. These are endoparasites which parasitizes in the gut. The body of the parasite Trichuris is divided into two parts. The thinner end of the head portion is inserted into the intestinal epithelial where obtains nutrients. Fat tail end is free in the intestine. The body is inarticulate. For this parasite is pronounced sexual dimorphism. Males have sexual spicules at the caudal end of the body. Females have a vulva, usually located at the transition from the thin head part to a stronger tail part of the body. Development cycle is no intermediate host. Animals become infected by ingestion of food containing egg with infective larvae. Development takes place through five larval stages. The generic name Trichuris is basically flawed and inaccurate, since it is based on the idea that the wire-thin body is part of the tail and thicker body part is the head (thrix = hair, ura = tail). Correct it later formed generic names Trichocephalus (Kefalo = head), which is also used in the literature as another name parasitic species Trichuris. However, it is still considered correct generic name Trichuris and disease caused by this parasite is therefore called trichuriosa.
