Figure 2From: Serogroup C meningococci in Italy in the era of conjugate menC vaccination Dendrogram of similarity obtained with Dice coefficients and arithmetic averages (UPGMA) clustering method using BioNumerics software (version 3.5) showing the relatedness of representative Pulsed Field Gel Electrophoresis patterns of Nhe I-digested DNAs of 147 C:2a and C:2b meningococci. Patterns that were <85% similar (see scale in the upper left corner) were considered different.Back to article page
