Introduction: The characteristics of cervicovaginal infections diagnosed by vaginal exudate are unknown, especially in middle-aged Cuban women. At other stages of the female life cycle, these studies have been done. Due to the importance of this information, to carry out health promotion actions, this research was carried out. Objective: To determine the characteristics of the most frequent cervicovaginal infections diagnosed by vaginal exudate. Method: A cross-sectional study was conducted in 1118 women. Age (grouped into 20-44 years and 45 and over), the results of positive vaginal discharge, the perception of presence or not of vaginal discharge (asymptomatic) and the microorganisms identified in the discharge were collected. Results: 49.9% of vaginal exudates were positive for bacterial vaginosis, Candidas albicans, Trichomonas vaginalis and imbalance in vaginal ecology. 45% of the patients had no vaginal discharge, that is, they were asymptomatic. Conclusion: Cervicovaginal infections were characterized by being of high frequency, usually asymptomatic, with prevalence of bacterial vaginosis, candidiasis and trichomoniasis.

OBJETIVO: El microorganismo Mycoplasma genitalium se ha relacionado con la uretritis no gonocócica (UNG). La técnica de PCR se ha convertido en el principal método de detección de este patógeno. En consecuencia, debe aplicarse un método de diagnóstico mediante la amplificación de fragmentos de ADN por la técnica PCR. MATERIAL Y MÉTODOS: Se seleccionaron los cebadores MGF-MGR y MgPaF-MgPaR, complementarios de los genes de ARNr 16S y MgPa de M. genitalium, respectivamente. Se efectuaron ensayos de especificidad y sensibilidad y se estudiaron muestras clínicas. RESULTADOS: La PCR con cada grupo de cebadores utilizado fue específica sólo para M. genitalium y la sensibilidad fue mayor con el grupo de cebadores MGF-MGR. En el estudio de 34 muestras clínicas, 18.5% fue positivo a M. genitalium y se encontró un mayor número de muestras positivas al utilizar los cebadores MgPaF-MgPaR. CONCLUSIONES: Debe aplicarse en la práctica clínica el diagnóstico de M. genitalium mediante la amplificación del ADN por PCR en los pacientes con UNG.OBJECTIVE: Mycoplasma genitalium has been associated with nongonococcal urethritis (NGU). Diagnosis by PCR has become the primary detection method for this organism. Thus, diagnosis by DNA amplification using the PCR technique should be utilized. MATERIAL AND METHODS: GMF/GMR and MgpF/MgpR primer pairs, complementary to the M. genitalium 16S rRNA and MgPa genes, respectively, were selected. Specificity and sensibility assays were conducted and clinical samples were studied. RESULTS: The PCR with each primer pair was specific only for M. genitalium, and the sensibility was higher with the GMF/GMR primers. In the study of 34 clinical samples, 18,5% were positive for M. genitalium, with more positive samples when the MgpF/MgpR primers were used. CONCLUSIONS: DNA amplification by PCR should be applied in clinical practice to the diagnosis of M. genitalium in patients with NGU should using.
