Chlamydia trachomatis genotypes in school adolescents, Italy.
Chlamydia trachomatis genogroups using ompA and multilocus sequence typing (MLST) were determined in consecutive isolates from school students aged 18 or older in the district of Brescia, Italy, 2012-2013. Among 40 samples, 4 ompA genovars and 18 STs were identified. Genovar E predominated (70 %) including five STs derived from ST59 (29 % of all isolates). This study, combining ompA and MLST typing of C. trachomatis school teenagers, suggests limited mixing and sexual interchange in this population.
