Abstract
Three species of trichostrongylid nematodes were removed from the gizzards of 25 lesser snow geese, Chen caerulescens caerulescens, collected at Winisk, Ont. A 100% prevalence of infection was noted in the sampled population with each bird harboring two or more of the following species: Epomidiostomum crami (prevalence, 92%; mean intensity, 18.7 ± 13.3), Amidostomum anseris (prevalence, 84%; mean intensity, 9.6 ± 9.8), and Amidostomum spatulatum (prevalence, 84%; mean intensity, 11.2 ± 9.8). When large burdens (>30) of both A. anseris and A. spatulatum were present in the mucosal lining of the gizzard, progressive degeneration of the epithilium and koilin linings was noted in 16% of the geese examined. Severe necrotic granulomata observed in the gizzard muscle of 36% of the geese were associated with sizable burdens (>25) of E. crami which were found burrowed in the gizzard muscle.
