Chlamydia trachomatis l serovars and dominance of novel L2b ompA variants, USA

摘要

Chlamydia tracbomatis serovars LI, L2, L3 cause lymphogranuloma venereum (LGV). An epidemic of proctitis due to L serovar infections (mostly L2b) has emerged primarily among men who have sex with men (MSM) in Europe.1 In the USA, limited availability of diagnostic testing for LGV hinders diagnosis and reporting to public health agencies. We hypothesised that LGV may be underdiag-nosed in the USA.
