Cumulative data from microarray-based CGH surveys of C. jejuni. (A) Divergent genes observed in data sets I, II, and III analyzed in this survey (see text). Of the 542 divergent genes observed in the collective data set, 209 are variable in two or more data sets (gray shading). The remaining 333 genes were variable in only one of the data sets. (B) Prevalence of genes divergent in a single strain (singletons) in three different C. jejuni CGH data sets. Whether analyzed separately or in various combinations (1, data set I; 2, data set II; 3, data set III; 4, data sets I and II; 5, data sets I and III; 6, data sets II and III; 7, data sets I, II, and III), a significant number of divergent singletons (striped bars) were obtained in the various data sets.
