*MLST, multilocus sequence typing; hctB, histone H1–like protein; pbpB, penicillin-binding protein; ompA, outer membrane protein A. Values are arbitrary designations referring to allele variants in our Chlamydia trachomatis MLST database (http://mlstdb.bmc.uu.se/). All MLST variants differ within regions with <5 point mutations unless otherwise indicated.
†Denmark (n = 7), France (n = 15), Germany (n = 1), the Netherlands (n = 9), Norway (n = 2), Spain (n = 6), and Sweden (n = 9).
‡ompA variant 28 is identical to the reference strain L2b/UCH-1/proctitis (AM884177.1).
§Spain.
¶ompA variant 39 contains a single point mutation compared with L2b/UCH-1/proctitis and has been deposited in GenBank under accession no. GQ413955.
#Baltimore, Maryland–Washington, DC.
**San Francisco, California.
††hctB variant 44 contains a novel 108-nt deletion and is unique in the MLST database.
‡‡ompA variant 40 contains 9 point mutations compared with reference strain L1/440 (DQ064294.1) and has been deposited in GenBank under accession no. GQ413956.
§§ompA variant 22 is identical to reference strain L2/434/Bu (AM884176.1).
