The purpose of this study was to examine the prevailing spectrum of nematodes, the infection intensity and the course of infection in ruminants, equines and pigs from a wildlife park in Lower Austria. From December 2014 to April 2015, 45 samples were collected in three enclosures for parasitological examination. All samples were examined by flotation method, the samples from ruminants and equines also by sedimentation method and Baermann technique. A quantitative evaluation by McMaster counting was performed in those samples where parasitic stages were detected. Overall, the prevalence was similar in all three samplings with 87.5 % in December, 78.57% in March and 80.0 % in April. Gastrointestinal strogyles were the dominant group of nematodes with a prevalence of 87.5 % in December, 78.57 % in March and 80 % in April. The faecal egg count was generally very low and increased only slightly until the third examination. Strongyloides was detected in all animal species except of pigs, but was only present in one of the samplings each. Capillaria was detected in sheep, goats and Wallachian sheep. Trichuris was detected in sheep and goats as well as the domestic pigs. One sample from cattle contained larvae of Dictyocaulus. Protostrongylids were detected in sheep, goats and Wallachian sheep once each. No nematodes were detected in pot-bellied pigs. In all animal species, except the pot-bellied pigs, multiple nematodes could be detected; however the faecal egg counts were very low and often entirely below the detection limit. Due to the small number of samples and sampling during the cold season there may have been an under-representation of some nematodes, making it difficult to estimate the actual prevalence and faecal egg counts. In summary, the results give a first overview of the nematodes of cattle, small ruminants, equines and pigs occurring in the wildlife park.
