title: The 7.5-kb plasmid present in Chlamydia trachomatis is not essential for the growth of this microorganism.
abstract: An L2 serovar of Chlamydia trachomatis, isolated from a patient with proctocolitis, has been identified that does not contain the common C. trachomatis 7.5-kb plasmid. This isolate was propagated in vitro showing that this plasmid is not required for the growth of C. trachomatis.
