Abstract: Growths of 6 strains of Japanese encephalitis (JE) virus were studied in mosquito (C6/36) and baby hamster kidney (BHK21) cell cultures at 4 different temperatures. At 28℃, 3 strains (Nakayama, Beijing-1, JaOArS982) grew slower than other 3 strains (JaGAr01, JaOH0566, ML17) in C6/36 cells although their infectivity increased from 1 day after infection. On the other hand, infectivity of all strains increased from 2 days after infection in BHK21 cells. At 33 and 37℃, growth of JaOArS982 strain in C6/36 cells was shut-off 2 and 1 day after infection, respectively, while growths of all strains in BHK21 cells were shut-off 2 days after infection. At 39℃, growths of all strains were shut-off 1 day after infection in both cell lines, and infectivity of Nakayama strain showed little increase in C6/36 cells. The results indicated some host cell factor(s) regulating replication of JE virus, especially in C6/36.
