FIG 1.
(A) Surface-associated motility assays of A. baumannii ATCC 17978 (WT) and 10 rifampin-resistant mutant derivatives (Rifr1 to Rifr10). (B) RpoB amino acid substitutions in the rifampin-resistant mutant strains and effects on motility (+, presence of motility; −, absence of motility). Mutants used in subsequent experiments are shaded.
