Emergence and spread of Chlamydia trachomatis variant, Sweden

Emerg Infect Dis. 2008 Sep;14(9):1462-5. doi: 10.3201/eid1409.080153.


A variant of Chlamydia trachomatis that had escaped detection by commonly used systems was discovered in Sweden in 2006. In a nationwide study, we found that it is now prevalent across Sweden, irrespective of the detection system used. Genetic analysis by multilocus sequence typing identified a predominant variant, suggesting recent emergence.
