ABSTRACT
In July 1997, a strain (GB30) of virus was isolated from 60 samples of brain tissues of Murina aurata (Chiroptera Vespertilionidae) co llec ted in Gengma county, Yunnan province, China. Isolation of virus was negative fr om 4 samples of brain tissues of Rousettus leschenaulti (Chiroptera Pteropo did ae) collected in Gengma. GB30 virus strain could regularly cause illness and dea th in suckling mice, produced evident CPE in BHK21 cells. It agglutinated red b lood cells of dove at pH5.75~7.4. This virus has been identified serologically by hemagglutination inhibition and immunofluorescent tests using Japanese enceph alitis (JE), dengue (DEN) type 1,2,3,4, and chikungunya (CHIK) viruses monoclona l antibodies, and JE and sindbis (SIN) viruses immune sera. It showed specific r eaction to JE virus only and no reaction with DEN 1~4, CHIK and SIN viruses. Th erefore it can be identified as JE virus. This is the first report on the isolat ion of JE virus from Murina aurata. The results showed that bats are conside red as the reservoir and amplifier host of JE virus transmission in nature.
