Eighty five faecal samples of the Svalbard reindeer inhabiting the coastal terrace of the northern side of Hornsund were collected in July 2005 and analyzed coprologically. The standard flotation method revealed a 97.6% prevalence of infection at an average intensity of 20 eggs in a single subsample. The quantitative, modified McMaster method helped to estimate the mean number of eggs in a gram of faeces (EPG) at 134.7. In the studied sampleseggs of nematodes representing two species, i.e. Ostertagia gruehneri (97.6%, on average 20 eggs in a sample) and Marshallagia marshalli (2.3%, single eggs), were identified.
