Summary Objective To determine the prevalence of Trichomonas vaginalis infection during the first trimester of pregnancy in pregnant women in a Maternity Institute.

Methods We contacted and recruited a total of 105 women with up to 3 months gestation who attended the outpatient. All of them filled out a consent form and were collected a sample of vaginal secretion, which was analysed for direct observation and inoculated into the culture medium InPouch TV (Biomed Diagnostics, White City, Oregon, USA) and incubated for up 72 h at 37°C. The samples were observed under the microscope for the presence of mobile parasites. Besides demographic data were collected.

Results The prevalence of infection with T vaginalis was 5.71% and 3.8% by culture and direct observation, respectively. The growing use of laboratory performance improvement in the report of the prevalence of T vaginalis. Close supervision of this parasite during pregnancy using more sensitive laboratory methods see Abstract P1-S1.26 Figure 1.
