Extrusions prolong survival of Chlamydia bacteria in dendritic cells. C57BL/6 BMDCs were exposed to C. trachomatis LGV L2 extrusions or dose-matched free bacteria. At the indicated hours postexposure, DCs were lysed by sonication and used to infect McCoy cell monolayers for quantification of IFUs. Data are means ± SEM of results of three independent experiments. *, P < 0.05; **, P < 0.01; ***, P < 0.001; ****, P < 0.0001.
