    Abstract:
    Vulvovaginitis accounts for 20 to 30% of gynecological diseases and it is observed in women from 20 to 30 years of age. It has a higher frequency in women using oral contraceptives and during the third trimester of pregnancy. The aim of this research was to assess the prevalence of Candida spp and Trichomonas vaginalis in patients with the diagnosis of vulvovaginitis from the Gynecology Service in Hospital Universitario "Ruiz y Páez" in Ciudad Bolívar and Hospital "Raúl Leoni" in San Félix (Bolívar State, Venezuela). Two hundred women with symptoms of vulvovaginitis were examined, and samples were taken from the uterocervical cul-de-sac. Each patient was asked to fill a questionnaire. The following studies were made in each sample: a) fresh wet mount examination, b) orange acridine and Giemsa stains for Trichomonas and c) culture for the identification of yeasts. The latter were identified by means of the germinal tube assay, resistance to actidione and the presence of clamidospores in rice-cream agar and sugar utilization test, using the commercial kit ID32C (BioMérieux). Only in 57 women of 200 patients with vulvovaginitis the causative agent was demonstrated; Candida spp was present in 84.2% (n = 48) and Trichomonas vaginalis in 14% (n = 8). A single case of Zygosaccharomyces spp (1.8%) was detected. The age group mainly affected was that of 25-35 years old, the 38.6% of the studied population. Candida species detected were: C. albicans in 87% of cases (n = 42), C. glabrata, in 10.42% (n = 5), and C. guillermondii, in 2.08 (n = 1). Vaginal flux, vulvar pruritus and leucorrhoea were observed in significant number of patients with vulvovaginal candidiasis. The use of antibiotics was considered predisposing factor for Trichomonas vaginalis infection. The relationship between age and the etiological agent was not statistically significant. Due to the low specificity of clinical manifestations of infections caused by Candida spp and Trichomonas vaginalis, we conclude that performing the etiologic diagnosis of vulvovaginitis is necessary in order to take the appropriate therapeutic and preventive measures, specially in those patients with a recurrent disease.
