Species distribution and susceptibility to azoles of vaginal yeasts isolated prostitutes.

Objective: We investigated the use of miconazole among female prostitutes in Costa Rica as well as the distribution of vaginal yeasts and the susceptibility pattern to azoles of strains obtained from this population. Our intention was to relate a frequent use of miconazole to occurrence of vaginal yeasts resistant to azoles.

Methods: Vaginal samples were taken from 277 patients that have previously used azoles.

Trypanosoma lewisi-induced immunosuppression: the effects on alveolar macrophage activities against Cryptococcus neoformans.

The immunosuppressive effect of Trypanosoma lewisi infection on alveolar macrophage (AM) activities against Cryptococcus neoformans was studied in an animal model. Two groups of rats were treated with T. lewisi and killed after 4 (4d-rats) and 7 days (7d-rats), respectively.
