HETEROSEXUAL TRANSMISSION OF A MURINE AIDS VIRUS

Heterosexual transmission of a murine leukemia virus mixture named LP- BM5 MuLV, which is known as the murine AIDS virus,,vas investigated. O ur results indicated that the heterosexual transmission of LP-BM5 MuLV occurs in both directions with high frequency and that the frequencie s of virus transmission in the cervix and penis are higher than those in other genital organs. The results suggested that infection by LP-BM 5 MuLV via heterosexual transmission may initially take place at parti cular retrovirus-sensitive sites (cells) in the genital organs.
