Four strains of Japanese encephalitis virus and 3 strains of group A arbovirus were isolated from mosquitoes of Aedes vexans nipponii caught in Nagasaki area during epidemic season from 1965 to 1968. The latter strains isolated were closely related to the strain MM 2021, Getah virus, a group A arbovirus. One of the isolates, MP 1805 strain, was found to be able to form plaques in primary chick embryo cell cultures with the plaque size of 2 or 3mm in diameter after 2 days incubation. By the method of plaque reduction, neutralizing antibodies against MP 1805 strain were detected in the sera of 4 of 47 cases which were acute febrile illness confirmed serologically as non-Japanese encephalitis and occurred during the period of epidemic season from 1964 to 1967. One of these 4 cases was found to have significant antibody rise in converescent serum.
