Screening of Volunteer Students in Yaounde (Cameroon, Central Africa) for<i>Chlamydia trachomatis</i>Infection and Genotyping of Isolated<i>C. trachomatis</i>Strains

Abstract

The prevalence of Chlamydia trachomatis infection 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 omp1 genes of 25 clinical isolates were E (44%) and F (20%), and some strains harbored mutations, but E genotype strains did not.
