Figure 4From: Comparisons of infant Escherichia coli isolates link genomic profiles with adaptation to the ecological nicheGene content enrichment comparing main clades 1 and 2. Enrichment analysis was carried out using criteria I (Table 2). Both enrichments were highly significant (p > 0.001). The distribution of possible strain group permutations is presented in Additional file 1: Figure S2.Back to article page
