FIG 1.

A. baumannii is susceptible to hBD-2 and hBD-3. Two strains of A. baumannii, AB0057 and ATCC 17978 (10,000 CFU/100 μl), were incubated with different concentrations of hBD-2 and -3, as described in Materials and Methods. hBD-3 was more effective at killing both strains. It eradicated both strains of A. baumannii at a 0.0625 μM concentration. hBD-2 was less potent than hBD-3 in killing A. baumannii. hBD-2 effectively killed both strains of A. baumannii at a 0.5 μM concentration. The results are the means of three independent experiments ± SDs.
