TABLE 1.

The effect of a slyA mutation on FimB inversion in rich-defined glycerol medium at 37° C from OFF-to-ON per cell per generation

Cells were grown for approximately 22 generations as described by Gally et al. (15). The mean, together with minimum and maximum values obtained for replicate cultures, are shown. The strains used are listed in supplemental materials.

Genotype	Inversion frequency (× 10−4)
Wild type	7.23 (1.1–29.2; AAEC370A)
slyA	0.58 (0.0–1.1; KCEC1360)
