Detection of Trichomonas vaginalis by different methods in women from Dohok province, Iraq

This study compared 4 different diagnostic methods for the detection of Trichomonas vaginalis in vaginal swab specimens from women attending a hospital in Dohuk in Iraq. A total of 425 vaginal swabs were obtained from women complaining of vaginal discharge associated with vaginitis, cervicitis and pelvic inflammatory disease. The results showed that 10 (2.4%) swabs were positive for T. vaginalis by wet smear preparation, 15 (3.5%) by haematoxylin–eosin stained smear, 17 (4.0%) by Papanicolaou stain and 23 (5.4%) using Diamond modified culture. The rate varied significantly by age and was highest in young women aged 20–25 years (7.6%) and lowest in the age group 36–40 years (2.2%). The highest rate of infection with T. vaginalis was detected by Diamond modified culture.
