Phenotypic characteristics of <i>E. coli</i> isolates showing an impaired growth.

aFirst number corresponds to the ID patient. The first isolate is the normal growth control. bThe experiments were repeated 3 times. The data are presented as the mean +/− standard deviation in brackets. cIn all cases, comparisons are made between isolates of the same patient. For the Biolog GN2, the total number of used carbon sources is indicated. See Table S4 for the complete list of carbon sources. For motility and H2O2 sensitivity, only two categories were considered: + corresponds to increased motility and H2O2 sensitivity as compared to −. dND, not determined because of the absence of growth. eSee material and methods for the categorization.
