Changing Pattern of Chlamydia trachomatis 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.
