Abstract

Summary and conclusion

1. Twenty days after 44 English sparrows were each inoculated with 140 chick LD₅₀ amount of WEE virus, the collected nasal mites were devoid of virus using Chamberlain's “wet” chick method of isolation. 2. Nasal mites of the English sparrow are probably not important vectors or reservoirs of Western encephalitis virus.
