The bacterium Pasteuria penetrans is a parasite of root-knot nematodes (Meloidogyne spp.). Endospores of P. penetrans attach to the cuticle of second-stage juveniles (J2) and subsequently sterilize infected females. When encumbered by large numbers of spo... see more

Diagnóstico y prevalencia de las infecciones vaginales en el Hospital General de Huambo, Angola Diagnóstico y prevalencia de las infecciones vaginales en el Hospital General de Huambo, AngolaObjetivo: determinar la prevalencia de infecciones vaginales en mujeres con o sin síntomas ginecológicos queasistieron a la Consulta de Ginecología del Hospital General de Huambo.Método: estudio transversal descriptivo realizado desde noviembre de 2011 hasta mayo de 2012 en 493 exudadosvaginales obtenidos de 172 mujeres embarazadas sin síntomas y 321 no embarazadas, con síntomas ginecológicos.A todas se les tomó muestra de la secreción vaginal para la realización de examen microscópico directo con soluciónsalina, coloración de Gram y cultivo en agar Sabouraud. Con los métodos aplicados se midió pH, se realizó test deamina, observación de “células guía”, presencia de Trichomonas vaginalis, levaduras e hifas.Resultados: dentro del total de muestras procesadas (493), hubo 354 positivas (67,2 %) y 139 negativas (32,8%). En ambos grupos, predominó el diagnóstico de vaginosis bacteriana (79,8 %), seguida de las infecciones por T.vaginalis, diagnosticada en 110 mujeres (34,2%) y Candida spp. en 35 (20,3%).Conclusiones: este trabajo muestra una prevalencia de infección vaginal en mujeres embarazadas sintomáticas.Se demuestra la importancia de la confirmación diagnóstica mediante métodos sencillos de laboratorio.Palabras clave: infecciones vaginales; prevalencia; Gardnerella vaginalis; Candida albicans;Trichomonas vaginalis.ABSTRACTObjective: to determine the prevalence of vaginal infections in women with or without gynecological symptoms who attended the Gynecology Consultation of the General Hospital of Huambo.Method: cross-sectional descriptive study conducted from November 2011 to May 2012 on 493 vaginal exudatesobtained from 172 pregnant women without symptoms and 321 non-pregnant women, with gynecological symptoms. All were sampled for vaginal secretion for direct microscopic examination with saline solution, Gram stain and culture on Sabouraud agar. With the applied methods pH was measured, amine test, observation of “guide cells”, presence of Trichomonas vaginalis, yeast and hyphae were performed.Results: within the total of processed samples (493), there were 354 positive (67.2%) and 139 negative (32.8%). In both groups, the diagnosis of bacterial vaginosis (79.8%) predominated, followed by infections by T. vaginalis, diagnosed in 110 women (34.2%) and Candida spp. in 35 (20.3%).Conclusions: this work shows a prevalence of vaginal infection in symptomatic pregnant women. The importanceof diagnostic confirmation through simple laboratory methods is demonstrated.
