RESUMEN
Background: Many infectious and noninfectious triggers lead to inflammation of the vagina. Aim: We investigated the prevalence of causative vaginitis microorganisms in 516 pregnant and nonpregnant female volunteers. Vaginal samples were examined microscopically, cultured and tested for different pathogens. Results: Of the participants, 310 (60.1%) were pregnant, whereas 206 (39.9%) were nonpregnant. Using Amsel's criteria and Nugent's scores, bacterial vaginosis (BV) was diagnosed in 59.1%, and the prevalence of vulvovaginal candidiasis (VVC) was 50.2% in the population. Candida infections were significantly higher in nonpregnant females (p value ≤ 0.01), and 24% of females had mixed infections. The most common mixed infection was BV and Candida spp., detected in 21% of the cases. Conclusions: Bacterial vaginosis is the most common cause of vaginitis. We observed that 24% of females experienced mixed infections, and Candida albicans was the most common fungal species causing VVC. Trichomonas vaginalis prevalence was underestimated using wet mounts.
