ABSTRACT
Trichomoniasis is a protozoan infection in lower urinary reproductive tract in males and females. It usually takes place in the fertility period in women and is transmitted through sexual inter course. To do this experiment, many females, referring to Taamin Ejtemayi hospital in Hamedan in 2005, were sampled among females for yearly cancer -test and smear, and then educated people under the supervision of the researchers examined the samples. In this study 400 females were selected in an improbable way and through simple sampling in the second half of 2005, and were examined by wet mount and culture procedure. Meanwhile, a questionnaire including questions pertaining to personal, social and hygienical status was administered and analyzed, using Epi 2000 statistical software. On prevalence rates, using wet mount and culture procedure were 2% and 3% respectively, and it was found that the highest percent of infection belonged to people aged 26-35, furthermore, rural areas were more infected than urban areas, however, it was not significant statistically. Among the women in the childbearing age, there was no statistically significant difference in terms of education and profession. It was also found that the number of pregnancies had no effect of on the rate of infection but using intravaginal contraceptive devices can increase the rate of infection. In this study, it was found that the prevalence rate in culture procedure is 1% more than direct procedure and that this procedure is more sensitive than direct procedure. Since proper diagnosis is the basis for correct treatment, it is recommended to use a culture procedure in cases, which a direct procedure turns out to be negative
