title: Binding, ingestion, and multiplication of Chlamydia trachomatis (L2 serovar) in human leukocyte cell lines.
abstract: We examined the ability of lymphoblastoid-myeloid cell lines to bind, ingest, and permit multiplication of Chlamydia trachomatis (L2 serovar). Four types of chlamydia-cell line interactions were observed: minimal bacterial binding; bacterial binding, followed by ingestion and high-level multiplication; bacterial binding, followed by ingestion but minimal multiplication; and bacterial binding, but minimal ingestion or replication. Our data demonstrate that at 37 degrees C in vitro the L2 serovar can both bind avidly to a cell without entering it and enter nonphagocytic cells but not grow.
