【Abstract】 In 1993, two strains of virus (HB49、HB97) were isolated from two Rousettus leschenauli sera captured in Hekou county, Yunnan province. Cross-HI、IFAT showed that HB49、HB97 could cross react with JE poly Ab、JE MAb. The isolates were 45 nm and in the brain tissue of the infected mice under the electron microscope. The brain tissues of the infected mice showed the pathological changes. TCID 50 of HB49 and HB97 were 5.33、4.50 respectively. LD 50 of HB49、HB97 were 3.5、3.67 respectively. HB49 and HB97 agglutinated RBC of dove at pH 5.75-6.8.更多还原
