| Meliae cortex (Melia azedarach Linne. var. japonica Makino, M. toosendan Siebold & Zucc) is one of the herbs used in oriental medicine for the treatment of various types of vaginitis. The present study was performed to examine the effects of Meliae cortex extracts on the growth and fine structure of Trichomonas vaginalis (T. vaginalis). Meliae cortex dose-dependently reduced the viability of T. vaginalis. In the electron microscopy study, we also observed the ultrastructural changes of T. vaginalis following the treatment with Meliae cortex. One to two hours after the addition of the extract of Meliae cortex, the movement of flagella and axostyle decreased, but the cell death did not occur. The fine structure of the cytoplasm was changed 30 min to 2... |

| El diagnóstico de laboratorio del parásito Trichomonas vaginalis, sigue siendo objeto de nuevos estudios. Así, Mendez y col., sugieren la utilización de un fijador-colorante con azul de metileno para el diagnóstico directo de este flagelado. En el presente trabajo se efectuó la validación de la mencionada propuesta frente al examen en fresco. Se analizaron cien flujos vaginales, obtenidos de fondo de saco, de pacientes a las cuales se les había solicitado examen microbiológico de flujo vaginal. Las muestras fueron recolectadas y procesadas siguiendo la técnica de fijador-colorante con azul de metileno, efectuándose, además, un examen en fresco del material obtenido, sin coloración, entre porta y cubreobjetos, antes de transcurrida la hora de la obtención.... |

| La coloración de Papanicolaou, además de la detección temprana del carcinoma de cuello uterino, brinda información sobre el estado hormonal y es orientativa al diagnóstico de infecciones cervicovaginales. La importancia de su detección y tratamiento radica en que pueden evitarse complicaciones posteriores, como enfermedad pélvica inflamatoria, ruptura prematura de membranas, abortos, sepsis del recién nacido, esterilidad. Se procesaron 251 muestras. Se estudió la correlación entre la información brindada por la coloración de Papanicolaou y el examen microbiológico (observación en fresco y coloración de Gram), con el fin de verificar la utilidad que puede brindar la coloración de Papanicolaou como alerta de las infecciones cervicovaginales. Para clasificar... |

| The interaction between each one of Trichomonas vaginalis and Tritrichomonas foetus with their hosts is a complex process in which components associated to the cell surfaces of both parasites and host epithelial cells, and also to soluble components found in vaginal/urethral secretions, are involved. Either cytoadhesion or the cytotoxicity exerted by parasites to host cells can be dictated by virulence factors such as adhesins, cysteine proteinases, laminin-binding proteins, integrins, integrin-like molecules, a cell detachment factor, a pore-forming protein, and glycosidases among others. How trichomonads manipulate informations from the extracellular medium, transduce such informations, and respond to them by stimulating the activities of some surface... |

| OBJECTIVES: Our goal was to determine the prevalence of Trichomonas vaginalis and its associated factors among women living with HIV attending an AIDS clinic in Manaus, Amazonas, Brazil. METHODS: Cross-sectional study among women attending an AIDS clinic in Manaus between March and December 2010 for gynecological examination were invited to participate. Enrolled patients answered a face-to-face interview including demographic, behavioral and clinical data. They also underwent a gynecological evaluation and cervical scrape samples were collected for wet mount, Gram stain, culture and cytological analysis. A blood sample was obtained to determine TCD4+ lymphocytes and viral load. RESULTS: A total of 341 (91.2%) women participated in the study. The prevalence... |

| Trichomonas vaginalis and Leishmania spp. are protozoal species responsible for millions of cases of parasitic diseases worldwide. Considering the potential of natural products and the need for more effective and less toxic alternatives to treat trichomoniasis and leishmaniasis, this study aimed to evaluate the effect of two series of triterpenes derivatives with different modifications at C-3 and C-28 positions of the ursolic acid (UA) and betulinic acid (BA) against trophozoites of Trichomonas vaginalis and promastigotes forms of Leishmania (L.) amazonensis. The compounds modified just at C-3 were the most active. The 3β-acetyl betulinic acid (1b) reduced the trophozoites viability of T. vaginalis at 74%, followed by the 3-oxo ursolic acid and 3-oxo... |
