title: Frequent detection of HIV-1 RNA but low rates of HIV-1 isolation in cervicovaginal secretions from infected women.
abstract: Information regarding the presence of HIV-1 in the female genital tract is necessary to gain insight into the mechanism of HIV-1 heterosexual transmission. Herein, we present the results of a study on virus isolation and HIV-1 RNA detection from cervicovaginal lavage (CVL) samples from 25 HIV-1 seropositive women. Despite detectable levels of HIV-1 RNA in 88% of CVL samples, HIV-1 was isolated in only four (19%) samples. Although HIV-1 shedding in cervicovaginal secretions is a common event at all disease stages, the recovery of infectious virus in cell cultures appears to be rare; this renders viral isolation in studies aimed to evaluate the infectivity of cervicovaginal secretions relatively useless.
