Abstract

<jats:p>Current information on the domestic yak (<jats:italic>Poephagus grunniens</jats:italic> or <jats:italic>Bos grunniens</jats:italic>) in the Himalayan agroecological zone in Nepal is limited. Despite their isolation, yak may contact other domestic livestock particularly during the winter when they are at lower altitudes and as such they may be exposed to infectious disease. Faeces from 50 adult yak from a herd of 123 adults and 27 calves in the Kaski region of the Nepali Himalaya were analysed for the presence of gastrointestinal parasites using standard flotation and sedimentation methods. In this herd, 18 per cent (95% CI 9% to 31%) of the samples showed evidence of nematode infection, with trichostrongyle and <jats:italic>Nematodirus</jats:italic>/<jats:italic>Marshallagia</jats:italic> species eggs being detected. No trematode eggs were detected in any samples, and no <jats:italic>Galba</jats:italic> species or other snails were found in the environment. The herd appeared healthy with low intestinal parasitic burdens. Our findings may indicate <jats:italic>Nematodirus</jats:italic>/<jats:italic>Marshallagia</jats:italic> species infection to be exclusive to yak in this region.</jats:p>
