High-resolution typing reveals distinct Chlamydia trachomatis strains in an at-risk population in Nanjing, China

Sex Transm Dis. 2013 Aug;40(8):647-9. doi: 10.1097/01.OLQ.0000431355.73217.df.


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.
