Figure 2. The bactericidal activity of silver acetate against exponentially growing Acinetobacter baumannii is concentration and time dependent.

Batch cultures of A. baumannii were grown at 37 °C with shaking to early exponential phase when silver acetate was added at final concentrations of 0, 0.98, 1.95, 3.91, 7.81 or 15.60 mg L⁻¹ (t = 0 h). Cultures were incubated for a further 24 h with viability determined at two-hour intervals to 8 h post-exposure (t = 2–8 h) and at 24 h. N = 3 ± SEM.
