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.
从一名患有直肠结肠炎的患者身上分离出一种沙眼衣原体L2血清型，该血清型不含常见的沙眼衣原体7.5 kb质粒。此分离株在体外进行传代培养，结果表明该质粒并非沙眼衣原体生长所必需。
