FIG 1.

C. muridarum is inhibited in RAW macrophages infected at a high MOI. (A) Macrophages were infected with C. muridarum at MOIs from 0.5 to 100. IFU assays were performed at 24 h p.i. (B to G) Light microscopy of macrophages either mock infected (B) or infected with C. muridarum at various MOIs (0.5 [C], 3 [D], 5 [E], 10 [F], or 100 [G]) at 18 h p.i. (H) Numbers of inclusions counted per cell in macrophages infected at different MOIs at 2 h p.i. The error bars represent standard deviations (SD).
