In North Dakota, during April 1998, a ranched female bison (Bison
bison) was found dead. At gross
necropsy, there was profound hair loss and consolidated lung lobes.
Intracytoplasmic neuronal inclusions suggestive of Negri bodies were
observed in the brain stem and hippocampus, and a diagnosis of rabies was
confirmed by the fluorescent antibody test.
Antigenic typing demonstrated the occurrence of a rabies virus variant
associated with skunks from the upper midwestern USA.
This case of a rabid bison was one of only four such instances recorded
from the USA over the past 40 years and is the first case reported of rabies in
a bison that reports clinical, pathological, and antigenic findings.
Although rabies in bison is rare, veterinarians and wildlife managers
that work closely with such non-traditional species are reminded of the dangers
that zoonoses such as rabies present.
Key words: American bison, Bison bison, case report, rabies, zoonoses.
