Dendrogram showing the genetic relationship of 69 invasive isolates of Group B streptococci established from PFGE patterns obtained after SmaI digestion. Dendrogram and PFGE patterns of SmaI-digested chromosomal DNA of Group B streptococci and association with capsular polysaccharide types, susceptibility to macrolides, macrolide resistance phenotypes, and the number of isolates belonging to these genotypes. The dendrogram was constructed with BioNumerics software, with 1.5% position tolerance, by using the UPGMA algorithm and Dice similarity coefficients. The clusters (clusters A, B, C, D, E, and F) contained isolates with similarity coefficients greater than 80% (indicated by the vertical line). Full-length gels are presented in Supplementary Data—Figures S4, S5, S6.
