Figure 2.
The fold-change between viable bacteria (CFU) of the indicated strains, calculated as the number of CFU in capillaries containing chemoattractant (2% methanol) divided by the number in control capillaries containing only CB (chemotaxis buffer). Error bars represent the standard deviation (SD) of the means. *P < 0.05 in a comparison with the A. baumannii parental strain (ATCC 17978) and based on at least nine independent experiments.
