Frequency of gastrointestinal and pulmonary helminth infections in wild deer from western Romania

A survey was carried out to assess the prevalence and the intensity of helminth infections in the roe deer (Capreolus capreolus L.), red deer (Cervus elaphus L.) and fallow deer (Dama dama L.) from 16 hunting areas in western Romania. Overall, 122 deer shot during the hunting season 2013–2015 were examined. Haemonchus contortus, Nematodirus filicollis, Oesophagostomum venulosum and Dictyocalus spp. were found in all the deer species. Trichuris spp. and Dicrocoelium dendriticum were found in the roe deer and red deer and Moniezia expansa in roe deer, only. Overall, the prevalences (< 35%) and the mean intensities (< 20) were quite low in the abomasums and intestine, but H. contortus in fallow deer (> 50%). No > 2 or 3 helminth species were found in the abomasum, small and large intestine. Lung helminthes in the roe deer and follow deer accounted for 57.1% and 71.4%, respectively. The only specie with a prevalence > 50% was in the red deer. D. dendriticum was found in the liver of roe deer and fallow deer.
