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.
