High-Resolution Typing Reveals Distinct Chlamydia trachomatis Strains in an At-Risk Population in Nanjing, China

In Brief We investigated Chlamydia trachomatis strains from Nanjing, China, and whether these strains differed from Amsterdam, the Netherlands. C. trachomatis type was determined with multilocus sequence typing. Most strains were specific to Nanjing, but some clustered with strains from Amsterdam. This demonstrates a geographical variation in C. trachomatis previously left undetected. High-resolution typing revealed distinct Chlamydia trachomatis strains in China. This demonstrates the existence of a geographical variation in C. trachomatis strains previously left undetected when only using ompA genovar typing.
