| isolation of pasteurella spp. from free-ranging american bison (bison bison). | from november 1991 through march 1992, nasal and pharyngeal swab samples were collected from 45 bison (bison bison) from yellowstone national park, montana (usa) and cultured for pasteurella spp. thirteen isolates of pasteurella spp. were recovered from 10 (22%) of the animals. ten isolates were from pharyngeal samples in contrast to three isolates from nasal samples. pasteurella haemolytica (six biotype t, two biotype a, and two biotype 3) was the predominant pasteurella species. five biotype t ... | 1996 | 8722271 |
| seasonal incidence and antibiotic susceptibility patterns of pasteurellaceae isolated from american bison (bison bison). | ninety pharyngeal tonsils were collected from 2-year-old american bison (bison bison) bulls and sampled for members of the pasteurellaceae family. particular attention was paid to seasonal incidence and antimicrobial resistance in serotypes and biovariants. multiple strains of pasteurella haemolytica (39%), p. trehalosi (68%), p. multocida (34%) and haemophilus somnus (13%) were cultured from 86 out of the 90 (96%) tonsil samples. pasteurella trehalosi was the most common and evenly distributed ... | 2001 | 11227200 |
| histophilosis as a natural disease. | histophilus somni is responsible for sporadic disease worldwide in cattle and, to a lesser extent, in small ruminants, bighorn sheep (ovis canadensis), and north american bison (bison bison). the importance of h. somni diseases can be attributed to improved clinical and laboratory recognition, combined with the growth in intensive management practices for cattle. although outbreaks of bovine histophilosis can occur year-round, in northern and southern hemispheres, it is most frequent in late fal ... | 2016 | 26847357 |
