Abstract
|
|

|
Birds were found to be rescrvoir of Japanese encephalitis virus (JEV) by isolation of the virus from birds by studies of Buescher and Scherer et al. It has been thought that birds might have relationship with overwintering mechanisms of JEV and Reeves et al succeeded in inducing artificial latent infection of Western equine encephalitis virus in hirds by inoculation of the virus, There is another hypothesis to explain the every-summer endemicity of Japanese encephalitis in the endemic area of temperate zone, that migrating birds of tropical areas carry the virus to the endemic area every spring or early summer but it was not proved. This experiment was carried out to isolate Japanese encephalitis virus and also to examine the frequencies of JE virus infection in migratory birds. It was found that about 7% of migratory birds collected in springs of Korea contained neutralizing antibodies to JEV but virus isolation was unsuccessful.
