| molecular subtyping of treponema pallidum subsp. pallidum in lisbon, portugal. | the objectives of this study were to evaluate the reproducibility of a molecular method for the subtyping of treponema pallidum subsp. pallidum and to discriminate strains of this microorganism from strains from patients with syphilis. we studied 212 specimens from a total of 82 patients with different stages of syphilis (14 primary, 7 secondary and 61 latent syphilis). the specimens were distributed as follows: genital ulcers (n = 9), skin and mucosal lesions (n = 7), blood (n = 82), plasma (n ... | 2009 | 19494073 |
| molecular typing of treponema pallidum clinical strains from lisbon, portugal. | a molecular system was used to subtype portuguese treponema pallidum clinical strains isolated from both skin lesions and blood. the study with this system constitutes the first typing study in a european country. three t. pallidum subtypes were found: subtypes 14a (50%), 14d (45.2%), and 14f (4.8%). further studies are needed to better characterize the isolates involved in syphilis outbreaks. | 2008 | 18753355 |
| association of trichomonas vaginalis with sociodemographic factors and other stds among female inmates in lisbon. | a 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 s ... | 2004 | 15339370 |
