Cat infected by a variant of bat rabies virus in a 29-year disease-free urban area of southern Brazil

Introduction: After 29 years, rabies was detected in a cat in Curitiba, southern Brazil. Methods: The fluorescent antibody test (FAT) and mouse inoculation test (MIT) were performed on central nervous system (CNS) samples. Results: Direct immunofluorescence was negative, but the biological test was positive and rabies virus was characterized as variant 4 (from Tadarida brasiliensis). Conclusions: Reappearance of rabies in domestic animals warns of sylvatic-aerial risk of infection and the necessity of monitoring bats in historically rabies-free areas.
