FIG. 1.
Dissipation of S. aureus membrane potential measured by flow cytometry with DiOC2(3). Cell populations exhibiting depolarization appear toward the left on the x axis. (A) Fully polarized (untreated) and depolarized (nisin, 8 μg/ml) cells; (B) depolarization of S. aureus by telavancin (TLV). The cultures were incubated for 15, 45, and 90 min in the presence of 8 μg/ml telavancin.
