|Abstract: ||Objective: To investigate the possible involvement of human trichomonads (Pentatrichomonas hominis and
Trichomonas tenax) other than Trichomonas vaginalis in the aetiology of vaginal trichomoniasis.
Methods: Vaginal swabs taken from women attending antenatal clinics were tested for Trichomonas vaginalis
by traditional assays (wet-mount microscopy and InPouch culture) and nucleic acid amplification (polymerase
chain reaction). These swabs were also tested for the presence of P hominis and T tenax by nucleic acid
amplification. Oral and rectal swabs from these women were tested for T tenax and P hominis respectively.
Data on sociodemographic characteristics, sexual and anogenital hygiene practices likely to seed P hominis
and T tenax into the vagina were collected by a questionnaire.
Results: 93% (161) of the 173 samples in which T vaginalis was detected by wet preparation or culture was
evaluable by PCR. Of this, T vaginalis was detected in 94% (152) by T vaginalis-specific PCR. Neither P
hominis nor T tenax was detected in any of the vaginal swab samples. These included nine samples for which
T vaginalis had been detected by wet preparation or culture, but were negative by T vaginalis nucleic acid
amplification. P hominis and T tenax were not detected in any of the rectal and oral swabs, respectively.
Conclusion: In this group of women, there was no evidence for the involvement of trichomonads other than T
vaginalis in the aetiology of vaginal trichomoniasis.|
