Dj. Kellock et Cp. Omahony, SEXUALLY ACQUIRED METRONIDAZOLE-RESISTANT TRICHOMONIASIS IN A LESBIANCOUPLE, Genitourinary medicine, 72(1), 1996, pp. 60-61
A lesbian couple in a monogamous relationship each presented with vagi
nal discharge demonstrable on culture to contain Trichomonas vaginalis
. Their symptoms had failed to respond to standard regimens of metroni
dazole, and subsequent microbiological sensitivities confirmed resista
nce of the trichomonads to metronidazole (minimum inhibitory concentra
tions in aerobic conditions > 8 mcg/ml). In addition, the couple denie
d use of penetrative sex toys or recent male partners, supporting the
concept of transmission through mutual masturbation.
