FIG. 3.

Effects of energy-depleting agents on the infection-induced increase in fluorescence (A and B) and φ13 adsorption (C). Experiments were performed at room temperature in LB medium. LM2509 (A and C) or HB10Y (B) cells were incubated with drugs for 5 min and then infected with R18-labeled φ13 (A) and φ6 (B) or unlabeled φ13 (C) particles at an MOI of 10 (A and B) or 0.1 (C). (A and B) 100% indicates the level of fluorescence 12 min p.i. in the absence of drugs. The final drug concentrations were 20 mM (A and B) or as indicated (C).
