Characteristics of bat rabies in Alberta.
Rabies in bats was monitored in Alberta from 1971 to 1978 Big brown bats replaced silver-haired bats as the species most frequently reported rabid during these years. Rabies infection was comparatively high among little brown bats in central Alberta in 1973 and has subsequently declined. Only one rabid little brown bat was discovered in southern Alberta which is populated by a different subspecies. Outbreaks of rabies in little brown and big brown bat colonies tended to be brief events. Observations of free-ranging bats with probable furious rabies suggested that bats do not generally identify humans as targets for attack. Independent trends in infection rates suggested that spread of rabies is primarily intraspecific but there is evidence that migratory bats play a role in introduction and maintenance of rabies in northern temperate bat communities. The dynamics of bat rabies in Alberta are discussed.
