Pseudorabies in captive coyotes.

Pseudorabies (Aujeszky's disease) was diagnosed in three adult captive coyotes (Canis latrans) from southern Indiana (USA). The coyotes died in their outdoor enclosure within a 48 hr period. Histopathology revealed multifocal, nonsuppurative meningioencephalitis and eosinophilic intranuclear inclusion bodies within neurons. Samples of brain were positive for pseudorabies virus by fluorescent antibody testing and virus isolation. Source of infection was the probable consumption of pseudorabies virus-infected pig carcasses.
