Comparison of sequenced K. pneumoniae cps loci. For each cps cluster, a two-way comparison with the clusters immediately above and/or below is presented. The K-type of each compared cluster is shown in red, followed by the strain/isolate identification and its NCBI accession number in parentheses. The blue segments connecting each cluster represent variably conserved (60–100% identity) regions among them (from a BLASTN comparison with e-value ≤ 10-4). Predicted glycosyltransferases are colored in orange, wzy and gnd homologs in yellow and purple, respectively. N.T., new K-type; N.D., K-type not determined.
