[Seroepidemiologic study of sexually transmitted diseases caused by Chlamydia trachomatis in Casablanca (Morocco)].
Screening 579 sera specimens obtained in Casablanca (Morocco) we have performed a retrospective seroepidemiological survey with regard to the prevalence of Chlamydia trachomatis involved in genital tract infections. The surveyed populations are divided into 3 groups: 177 patients affected with sexually transmitted diseases (STD), 319 reference patients, 83 maghrebian patients affected with STD but living in France. The study was performed by the indirect microimmunofluorescence technique. The prevalence of Chlamydia trachomatis ranging from 50% in the moroccan reference groupe to about 70% among patients with STD both in Morocco and Bordeaux indicates that Chlamydia trachomatis takes a significant part in STD observed in moroccan populations.
