- Association of Trichomonas vaginalis with sociodemographic factors and other STDs among female inmates in LisbonPublication . Garcia, A; Exposto, F; Prieto, E; Lopes, M; Duarte, A; da Silva, RCA study on STDs was conducted among 211 female inmates in a prison in Lisbon, Portugal, in order to establish possible associations between Trichomonas vaginalis infection, sociodemographic factors and other STDs. T. vaginalis was found in 31.2% of the women, from whom only 65.1% presented symptoms. It was more frequently isolated in the 20-40 year age group. On univariate analysis there was an association, although not statistically significant, between the existence of T. vaginalis, multiple sexual partners, drug addiction and no condom use. A statistically significant association was found between trichomoniasis, prostitution and other STDs. These were found in 87% of all women. T. vaginalis was detected alone in 23.8% (15/63) of all women with trichomoniasis, while 76.2% (48/63) of them had multiple infections with trichomonas and other STDs. A statistically significant association was present between trichomoniasis and Mycoplasma hominis and infection with Treponema pallidum. This study showed that the prevalence of T. vaginalis is as high as that of multiple infections with other STDs. Therefore, our findings seem to confirm that trichomoniasis serves as a marker for other STDs. Screening for STDs should then be offered to Portuguese inmates, or, at least, these women should be screened for T. vaginalis, as a marker for the other STDs.
- Genital mycoplasmas in women attending a family planning clinic in Guine-Bissau and their susceptibility to antimicrobial agentsPublication . Domingues, D; Tavira, LT; Duarte, A; Sanca, A; Prieto, E; Exposto, FA study on the prevalence of genital mycoplasmas and their susceptibility to the most common antimicrobial agents used for treating the infection was conducted on 94 women attending a family planning clinic in Guine-Bissau. Fifty-four women (57.4%) were positive for Mycoplasma hominis and/or Ureaplasma urealyticum. M. hominis and U. urealyticum separately isolated from infected women yielded frequencies of 31.5 and 27.8%, respectively, the remainder were infected with both species. No strain was found to be resistant to all three commonly employed antibiotics for the management of these infections (erythromycin, tetracycline and ofloxacin), although multiple resistance to two antibiotics was frequent, especially when both genital mycoplasmas were present. Some 90.7 and 24.1% of all isolates were resistant to erythromycin and tetracycline, respectively. No resistance was observed to ofloxacin, although 50% of the strains had intermediate resistance. The high prevalence of genital mycoplasmas in women attending a family planning clinic in Guine-Bissau, as demonstrated in this study, appears to be associated with trichomonosis and bacterial vaginosis. These infections were also found to be highly resistant to erythromycin and tetracycline and to have intermediate resistance to ofloxacin. However, further studies are necessary to establish the burden of infection due to antibiotic resistant genital mycoplasmas. (C) 2003 Elsevier Science B.V. All rights reserved.
