Interpretive Summary: Use of goats for packing gear into wilderness areas is gaining popularity with hikers. Because of their increased use, there is concern regarding potential transmission of disease agents from pack goats to wild ruminants, especially bighorn sheep. Our objectives were to identify and classify Pasteurella spp isolated from the pharynx of pack goats and to determine whether vaccination with a commercial vaccine would affect the ability to isolate the organisms. Multiple strains of the organism were isolated. Vaccination did not decrease the proportion of isolations.

Technical Abstract: Use of goats for packing gear into wilderness areas is gaining popularity with hikers. Because of their increased use, there is concern regarding potential transmission of disease agents from pack goats to wild ruminants, especially bighorn sheep. Our objectives were to identify and classify Pasteurella spp isolated from the pharynx of pack goats and to determine whether vaccination with a commercial vaccine would affect the ability to isolate the organisms. Pharyngeal swab specimens were collected from 45 domestic pack goats on day 0, before vaccination with a commercial Mannheimia haemolytica serotype A1 bacterin. Specimens were collected again on days 21 and 35 from 17 of the goats. Multiple strains of Pasteurella spp were isolated and assigned to 30 non-hemolytic and to 14 hemolytic biovariant groups. The most common isolate, from 41 goats, was non-hemolytic P. trehalosi belonging to group 2. Non-hemolytic P. haemolytica strains were isolated from 31 goats, hemolytic strains from 35 goats, and hemolytic strains of P. trehalosi were isolated from 8 goats. Vaccination did not decrease the proportion of isolations.
