FIG 3.

ST-669 inhibits growth of Coxiella burnetii and Chlamydia spp. in a host-specific manner. qPCR analyses of ST-669- and DMSO-treated Coxiella burnetii (A; 72 h postinfection), C. muridarum (B; 20 h postinfection), C. trachomatis L2 (C; 40 h postinfection), and C. caviae GPIC (D; 40 h postinfection) inside McCoy (black) or Vero (gray) cells. All experiments were conducted at an MOI of 1. Genome copies/ml are plotted on the y axis. The asterisk indicates statistically significant differences (P < 0.0001).
