Résumé

Mycoplasmaspp. and Ureaplasmaspp. belong tohumans'genitourinary microbiota and sometimesare associated with infections of the genitourinarytract. The aim of this study was to evaluate the occurrence of Mycoplasmaspp. and Ureaplasmaspp. in genital specimens from patients of the 15thRegional de Saúde of ParanáState, Brazil, and to correlate the results with clinical and laboratory data.A retrospective cross-sectional study was conducted,based on the analysis of results of vaginal, endocervical, urine andurethral culture for mycoplasmas from patients attended in areference laboratory, from January 2009 to December 2016. We evaluated 2,475 results of culture for mycoplasmas. A total of 50.8% patients were positive for mycoplasmas. Of these, 76.8%had positive culture exclusively for Ureaplasmaspp. and 4.7% for Mycoplasmahominis. Both microorganisms were isolated in the microbiology culture of 18.5% of patients. Among the positive culture, 81.4% had significant concentrations.Bacterialvaginosis was the most common alteration observed in association with mycoplasmas.Thehigh positivity of cultures for mycoplasmas, especially Ureaplasmaspp. found in our study, highlightthe presence of these microorganisms in many of the genital tract disorders that can be sexually transmitted and, consequently, should not be neglected.

Résumé

Genitourinary myiasis, associated with ulcerating lesions and poor hygiene of the local site, has been infrequently reported. We report a case of 45 year-old urinary incontinent female suffering from carcinoma cervix, who presented with genitourinary myiasis. The larva was identified as of Chrysomyia bezziana Villeneuve (C. bezziana).

Résumé

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 molecules and/or releasing enzymes are the aspects concerning trichomonal virulence which are here briefly reviewed and discussed.
