Kasokero virus: a new human pathogen from bats (Rousettus aegyptiacus) in Uganda.

Two virus strains were isolated by mouse inoculation from blood of Rousettus aegyptiacus fruit-eating bats collected from Kasokero Cave in Uganda. Shortly after these strains were introduced in the laboratory, four additional strains were recovered from laboratory workers who had developed mild to severe illnesses presumably as a result of laboratory infection. Serological studies established that these six isolates are strains of the same virus. Serological tests showed also that this virus is related to Yogue, an unclassified virus.
