A COMPARATIVE STUDY ON THE SENSITIVITY OF TWO DIFFERENT DIAGNOSTIC WAYS OF DIAMOND CULTURE AND WET MOUNT IN TRICHOMONAS VAGINALIS DIAGNOSIS AND CORRELATION BETWEEN INFECTION AND CLINICAL FINDINGS

Background & Aim : Trichomonas vaginalis is a flagellate protozoa which can be found in urinary canal, cervix and vagina of contaminated persons. The disease affected by this parasite is called trichomoniasis. The common way to diagnose the disease is applying wet mount method with 60% sensitivity; this study tries to compare two different ways of wet mount and Diamond culture to diagnose Trichomonas Vaginalis. Materials & Methods : In this study, vaginal discharges of 420 women referred to Health Care Center No 15 of Urmia Medical Sciences University were collected and examinated by two different methods; wet mount and Diamond Culture. Finally they were compared. Results : From all of cases, 11 (2.6%) of them had parasite in their sample, but the results of parasite culture showed contamination in 10 cases (2.4%). In this study, sensivity of two methods ( wet mount and Diamond Culture) were 100% and 90.9% . Statistical data showed that there is a significant relationship between rate of contamination and clinical findings (p<0.05). Discussion : As Diamond culture has got a high sensitivity comparing to the other methods, the difference between different ways of wet mount and Diamond culture can be explained by the factor that in transmitting the test tubes, most probably the parasites are lysed. It can be justified by inappropriate parasites culture conditions, too.
