Screening of Volunteer Students in Yaounde (Cameroon, Central Africa) for Chlamydia trachomatisInfection and Genotyping of Isolated C. trachomatisStrains

ABSTRACTThe prevalence of Chlamydia trachomatisinfection was 3.78% out of 1,277 volunteer students screened by direct fluorescence assay and Cobas Amplicor PCR. The infection was associated with the nonuse or inconsistent use of condoms in women (P= 0.026) and a previous sexually transmitted infection in men (P= 0.023). The most frequent genotypes determined by sequencing the omp1genes of 25 clinical isolates were E (44%) and F (20%), and some strains harbored mutations, but E genotype strains did not.
