Fig. 1From: Genotypic diversity and phenotypic traits of Streptococcus mutans isolates and their relation to severity of early childhood cariesDendrogram with genetic similarity indices (AP-PCR method, primer OPA-02) verified among S. mutans strains sampled from biofilm of CF, ECC and S-ECC children. Individual bands were analyzed by matrices generated by UPGMA analysis using coefficient SSM (simple matching). Tonalities of gray in the dendrogram illustrate identical or highly related isolates (SSM ≥ 0.819 ± 0.161)Back to article page
