Trichomoniasis and associated co-infections of the genital tract among pregnant women presenting at two hospitals in Ghana

BACKGROUND Trichomonas vaginalis (TV) infection is the most prevalent non-viral sexually transmitted pathogen worldwide. Among pregnant women, the infection may cause adverse birth outcomes such as premature rupture of membranes and premature labour. In view of the paucity of information relating to TV among Ghanaian pregnant women, this study investigated its prevalence and associated co-infections among pregnant women. METHODS High vaginal swabs were obtained from 99 pregnant women using sterile cotton swab sticks. Wet preparation, Grams staining, culturing, coagulase and sensitivity testing were carried out to determine the presence of TV and associated microorganisms. RESULTS The prevalence of TV among the pregnant women was found to be 20.2% (n = 20). Concurring with Trichomoniasis, 75% (n = 15) of participants had other infections such as Candida with prevalence of 53% (n = 8), Proteus infection - 20% (n = 3), Streptococcus infection - 13% (n = 2) and other GNRs and Gonococci having 7% each (n = 1). Moreover, there was 86.9% (n = 86) prevalence of Staphylococcus spp. among study participants. There was statistically significant correlation between TV and Gonococci infection at a correlation co-efficient of 0.107 (P < 0.05) as well as significant correlation between TV and Proteus spp. at a correlation co-efficient of 0.189 (P < 0.05). TV infection was high (60%) among the most sexually active age group (19 to 29 yrs). CONCLUSION There was 20.2% prevalence of TV among the pregnant women presenting at the hospitals, with Gonococci and Proteus infections being statistically significant associated infections.
