Transmission of Chlamydia trachomatis and Neisseria gonorrhoeae among infected men and their female sex partners was examined using a design enhancing the likelihood that spread was directed from men to women.
Chlamydia culture-negative specimens were examined using DNA amplification tests.
Infection rates in women exposed to male sex partners with Chlamydia only were 65% (20/31) and with gonorrhea only were 73% (33/45).
Infection of women by either agent was not influenced by the number of sexual exposures to or coinfection in men.
There was a 98% (40/41) concordance of N. gonorrhoeae isolates among partners by auxotype and serovar.
Chlamydia isolates were serotyped using ELISA and immunofluorescence testing and confirmed by nested polymerase chain reaction : 50% (6/12) of men and 57% (8114) of women yielded mixed serovars.
Sixty-four percent of pairs (9114) were infected with identical serovars and an additional 28% shared at least one serovar.
Multiple serovars of C. trachomatis, but not of N. gonorrhoeae, were common in sex partners and exchanged frequently.
