Vampirebats are susceptible to artificial inoculation with the virus of rabies. The disease thus produced may be of the furious or the paralytic type, or there may be no clinical symptoms. Vampirebats caught in natural conditions, may be found to be unduly exited and "furious", or may appear healthy without evidence of disease. They may, however, in both cases be infected with rabies. Vampirebats may become carriers of rabies after "recovery" from the furious form of the disease. In this state they may remain capable of spreading infection by their bites for prolonged periods.
