Nemabiome metabarcoding of wild conservation bison herds and co-grazing cattle reveals different species compositions and low-level benzimidazole resistance.

ABSTRACT: Gastrointestinal nematodes (GIN) live in complex communities within American plains bison (Bison bison), a keystone ungulate species of North American prairie ecosystems. These trichostrongylid nematode species vary in their level of pathogenicity and can cause disease ranging from subclinical to clinical. However, the GIN species diversity and distribution of North American bison are understudied, especially in conservation herds in the United States. Fecal samples from conservation bison were collected from six herds in 2022, with five of those herds resampled in 2023 across six states (Colorado, Iowa, Nebraska, North Dakota, South Dakota, Oklahoma). Fecal samples from a herd of longhorn cattle that co-graze with a bison herd from Oklahoma were also collected in both years. Follow
