The nematode Ashworthius sidemi is a typical parasite of Asiatic deer, particularly sika deer (Cervus nippon). It was probably first carried into Poland by migrating red deer. The aim of the present study was to determine the prevalence and intensity of A. sidemi infection in roe deer and red deer in the Lower Silesian Wilderness in the winter season 2015/2016. Parasitological necropsy of 34 abomasa of red deer from Forest District Ruszów was performed. The prevalence of A. sidemi infection was found to be 91.1%, and the intensity to range from 10 to 2680 nematodes, with a mean intensity of 394 parasites. This prevalence of ashworthiosis and maximum intensity of infection were respectively 17.2% and 38% higher than observed in the previous season (2013/2014). The mean intensity was also slightly higher than reported previously.
