Detection of Lymphogranuloma Venereum- associated Chlamydia trachomatis L2 Serovars in Remnant Rectal Specimens Collected from Seven United States Public Health Laboratories.

ABSTRACT The frequency of lymphogranuloma venereum (LGV) or invasive Chlamydia trachomatis (CT) infection with serovar L1, L2 or L3 is unknown in the United States. While no diagnostic test is commercially available, we used a laboratory-developed test and detected LGV-associated serovar L2 in 14% of 132 remnant CT-positive rectal swabs.
