Journal of Parasitology 39(5): 538-546
Of 292 Alaskan ptarmigan, Lagopus spp., examined, 37% were found to be infected with helminths, viz., five species of nematodes, two species of trematodes and four species of cestodes. Trichostrongylus tenuis from the North American ptarmigan, Leucochloridium variae, Brachylaima fuscata, Aploparaksis galli and Davainea proglottina from the willow ptarmigan and Rhabdometra nullicollis from the rock ptarmigan are recorded for the first time.
