Figure 1

Clusters of orthologous groups (COG) analysis of all genes and all proteins which were detected at least once in the E. coli isolates (A) and in the K. pneumoniae isolates (B). X-axis: The major functional COG families. Y-axis: The proportion of genes and proteins that were detected in both species compared to the COG database. Genes are represented by solid bars and proteins are represented by interrupted bars.
