A total of 288 rabies-virus samples from 17 Latin American and Caribbean countries were reacted with an array of monoclonal antibodies. Identification of eight distinct antigenic variants among these samples permitted epidemiologic studies of the geographic distribution of different concentrations of rabies in the region and of the animal species serving as maintenance sources for rabies within a concentrated area. Two variants were broadly distributed and associated with enzootic disease in dogs and vampire bats. All isolates from cases of human rabies contained one of these two variants. Two variants had a limited distribution: an outbreak in Brazil, primarily affecting dogs and believed to be maintained by dog-to-dog transmission, and nine cases of rabies in cattle in Venezuela, animal reservoir unknown. A reservoir of rabies in insectivorous bats was identified and the associated variant was found in a rabid domestic cat. The remaining three rabies variants were found in single isolates only, but due to inference from antigenic-typing data from North American samples, were believed to be maintained by reservoirs of rabies in hoary bats, foxes, and skunks.
