First case of sexually transmitted asymptomatic female genital tuberculosis from spousal epididymal tuberculosis diagnosed by active screening

Tuberculosis screening was performed for a healthy asymptomatic woman to determine whether she had been infected with active genital tuberculosis via sexual intercourse with her husband who had epididymal tuberculosis. Vaginal swab culture yielded Mycobacterium tuberculosis. Furthermore, whole genome sequencing revealed that the two causative isolates were genetically identical. This appears to be the first report on the sexual transmission of genital tuberculosis from a man to an asymptomatic woman, detected by active screening for genital tuberculosis and molecular analysis, including whole genome sequencing. Active screening for genital tuberculosis in the female partner should be considered soon after diagnosis of male genital tuberculosis, even when the female partner is asymptomatic.
