Serologic Evidence of Lyssavirus Infections among Bats, the Philippines

摘要

Active surveillance for lyssaviruses was conducted among populations of bats in the Philippines. The pres-ence of past or current Lyssavirus infection was determined by use of direct fluorescent antibody assayson bat brains and virus neutralization assays on bat sera. Although no bats were found to have activeinfection with a Lyssavirus, 22 had evidence of neutralizing antibody against the Australian bat lyssavirus(ABLV). Seropositivity was statistically associated with one species of bat, Miniopterus schreibersi.Results from the virus neutralization assays are consistent with the presence in the Philippines of a natu-rally occurring Lyssavirus related to ABLV
