Antibiotic susceptibilities of 1-month anaerobic B. pseudomallei cultures. One-month anaerobic cultures were treated for 6 h (open bars) or 24 h (shaded bars) at final concentrations of 64 μg/ml ceftazidime (CAZ), 256 μg/ml chloramphenicol (CHL), 256 μg/ml trimethoprim-sulfamethoxazole (SXT), 32 μg/ml metronidazole (MTZ), and 12 μg/ml tinidazole (TNZ). EtOH, ethyl alcohol. Error bars represent standard deviations for three independent cultures for each treatment per time point presented.
