          Abstract

          Se realizó un estudio con 105 muestras de biopelícula dental supragingival, procedentes de igual número de estudiantes de la Unidad Educativa Estadal Bolivariana “Blanca Sosa de Vargas” de Ciudad Bolívar, con el objetivo de determinar la prevalencia de Entamoeba gingivalis y Trichomonas tenax. Las muestras fueron analizadas mediante las técnicas de examen directo, examen del sedimento y coloración tricrómica. Entamoeba gingivalis fue el único protozoario diagnosticado en 32 de las muestras. No hubo diferencia en cuanto al género y la edad de los estudiantes infectados (p>0,05). El protozoario se diagnosticó en niños con y sin caries por lo que no hubo diferencias estadísticamente significativas. En conclusión, se determinó una prevalencia de E. gingivalis de 30,5% en muestras de biopelícula dental de la población estudiada

          A study of 105 supragingival dental biofilm samples taken from the same number of students of the “Blanca Sosa de Vargas” Bolivarian State Educational Unit of Ciudad Bolivar was done with the purpose of determining the prevalence of Entamoeba gingivalis and Trichomonas tenax. The samples were analyzed through direct examination, sediment examination and trichrome staining techniques. Entamoeba gingivalis was the only protozoa diagnosed in 32 of the samples. There was no difference in relation to gender and age of the infected students (p>0.05). The protozoa were diagnosed in children with and without caries and there were no statistically significant differences. In conclusion, a 30.5% prevalence of E. gingivalis was determined in dental biofilm samples from the population studied

          Pulmonary trichomoniasis and Trichomonas tenax.

          S Hersh (1985)
          Pulmonary trichomoniasis is usually caused by aspirated Trichomonas tenax. Adult men with chronic purulent or necrotic pulmonary disease are usually affected. Sixty-eight patients were previously described. A Russian study demonstrated pulmonary trichomoniasis in 19 of 112 patients (17%), mostly in patients with lung cancer, lung abscess, or bronchiectasis. Rarely, pulmonary trichomoniasis may be caused by an intra-abdominal (T. hominis) or genitourinary (T. vaginalis) infection. T. tenax is usually regarded as a harmless commensal of the human mouth. Its prevalence ranges from 4% to 53% and may exceed that of vaginal infection with T. vaginalis in adult females. It is frequently found in patients with poor oral hygiene. Cultural identification is superior to microscopic examination of wet-smear, gram-stained and Papanicolaou-stained preparations. Aspirated pulmonary trichomoniasis is an opportunistic infection. Until the question of possible pathogenicity is resolved, metronidazole should be given. The underlying pulmonary disease should be vigorously treated.

              Empyema Caused by Trichomonas

              Empyema is one of the potential complications of lower respiratory tract infections. Very rarely, in predisposed individuals, empyema can be caused by Trichomonas species, of which Trichomonas tenax appears to be the most common cause. Here, we present a case of trichomonal empyema in a 56-year-old man and review the available literature of this rare occurrence.
