1. Dendrogram constructed on the basis of RiboPrint pattern types obtained for 13 complement-sensitive and 2 complement-resistant strains of M. catarrhalis (235).
Dendrogram constructed on the basis of RiboPrint pattern types obtained for 13 complement-sensitive and 2 complement-resistant strains of M. catarrhalis (235). Selected were those RiboPrint patterns that are representative of the diverse genogroups that could be identified. The resistant strains appear to be a more homogeneous group (only 2 closely related types encountered among 47 strains) than are the complement-sensitive strains. The tree was constructed in the BioNumerics program developed by Applied Maths (Kortrijk, Belgium). On the basis of Pearson coefficients and unweighted pair group method using arithmetic averages (UPGMA), patterns were normalized using molecular size markers coanalyzed during pattern creation. The 40 to 100 scale above the dendrogram indicates the percent identity between fingerprints compared. The fully automated RiboPrinter has been developed and marketed by Qualicon, a Dupont subsidiary (Warwick, United Kingdom).
