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.
2012 - 2013年，在意大利布雷西亚地区对18岁及以上在校学生的连续分离株进行了沙眼衣原体基因组群的ompA基因分型和多位点序列分型（MLST）。在40个样本中，鉴定出4种ompA基因变种和18种序列型。基因变种E占主导（70%），包括源自ST59的5种序列型（占所有分离株的29%）。这项结合了沙眼衣原体在校青少年ompA基因分型和MLST分型的研究表明，该人群中的混合感染和性传播有限。
