Dendrogram and PFGE patterns of NheI-digested chromosomal DNA of Neisseria meningitidis isolates and their association with serogroup, assigned PFGE code, ST code, and clonal group/complex. The dendrogram was constructed using BioNumerics software, with 2% optimization and 0.8% position tolerance, using the UPGMA algorithm and the Dice similarity coefficients. Dark circle (●) indicates a clonal group/complex. The sizes of the DNA bands from the marker strain (M413) are indicated in kb. Asterisk (*) indicates the ST sequence identified for the first time in this study.
