The study was aimed at evaluating the extent of gastrointestinal and pulmonary helminth infections in the fallow deer in Northwest Poland. Infection prevalence and intensity as well as the species composition of helminth fauna were determined. During about 2-year period, since March 2000 until February 2002, a total number of 52 animals and 98 faecal samples were examined. The fallow deer were shot during routine culls in 9 forest districts. We have found 12 gastrointestinal and 2 lung nematode species in fallow deer in NW Poland. The most common gastrointestinal species were Oesophagostomum venulosum, Spiculopteragia boehmi, Haemonchus contortus and Nematodirus spp. Other species were determined in a lower intensity. Two lung nematode species Elaphostrongylus cervi and Varestrongylus sagittatus were found, with their prevalence 59.6% and 46.1%, respectively.
Coproscopic examinations of mouflons Ovis aries musimon from four forest districts of Lower Silesia performed in spring and autumn from 2012 to 2014 demonstrated the presence of pulmonary nematodes and intestinal parasites, including coccidia of the genus Eimeria. Prevalence of pulmonary nematodes (mainly Muellerius capillaris) amounted to 69.78%, intestinal nematodes – 56.11% and coccidia of the genus Eimeria – 44.6%. The number of oocysts, eggs of intestinal helminths and larvae of pulmonary nematodes was low. Most frequently the parasites occurred in mouflons from the Jugów forest district, which is related to contact with sheep grazed in the area.
