Changing Pattern of<i>Chlamydia trachomatis</i>Strains in Lymphogranuloma Venereum Outbreak, France, 2010–2015

Abstract

We describe a change in the molecular epidemiology of Chlamydia trachomatis strains involved in an outbreak of rectal lymphogranuloma venereum in France during January 2010-April 2015. Until 2012, the C. trachomatis L2b strain predominated; however, starting in 2013, most cases involved the L2 strain. We also identified 4 genetic L2b ompA variants.
