Heinclová, Pavla ; Langrová, Iva (advisor) ; Vynikalová, Lucie (referee)
This study is focused on the occurrence of gastrointestinal nematodes in cervids in the Czech Republic. The aim of the study was to determine the species composition of gastrointestinal nematodes of roe deer (Capreolus capreolus) and fallow deer (Dama dama) . Research on presence of parasites in the digestive tract of roe deer and falow deer was done by using autopsy which was performed in the laboratory of the Department of Zoology and Fisheries FAPPZ CULS Prague according to K. I. Skrjabin.
Autopsy material was extracted from small intestine of the captured pieces during the years 2009 - 2014. Research was done on 15 deer coming from Central Bohemia, Ústí and Liberec region. For determination were used microscope and determination key. Among determination characteristics determined in females include overall length of the body width, shape and size of the vulva, the presence of flaps, vulva distance from the anus, the shape of the end of the body. Males observed features: overall length, size and shape of spicules, gubernaculum.
Among the common features observed included the formation of the pharynx and oral capsule. Each of the nematode was measured and incorporated into species and genera. Result shows nematodes: Trichostrongylus capricola, Nematodirus fillicolis venulosum and Oesophagostomum, Cooperia pectinata and subsequently evaluated prevalence.
From the results of the autopsy of the small intestine shows that the highest prevalence rate among deer and fallow deer reaches Trichostrongylus capricola (60 %) and Nematodirus filicollis (20 %). The lowest prevalence consistently achieve Oesophagostomum venulosum and Cooperia pectinata (6.7 %). The prevalence was consistent with studies carried out in other European countries. In comparison with studies in the Czech Republic with Trichostrongylus capricola was compared to another research from 2008 to decrease prevalence.
