ftsI phylogram. UPGMA phylogram of ftsI DNA sequences (transpeptidase domain, nucleotides 1010–1719) in the current (n = 196) and previous study (n = 46) [11]. The outgroup (Hpar) is H. parainfluenzae [EMBL:AB267856] and the reference sequence (z0) is H. influenzae Rd KW20 [GenBank:U32793]. The H. influenzae reference strains ATCC 49247 and ATCC 49766 are also included. The scale is DNA sequence divergence (0.05 = 5% divergence). Labels indicate ftsI alleles, PBP3 types and number of isolates with the particular allele in the previous and current study, respectively. The reference cluster alpha (green) and the alleles encoding PBP3 types A, B and D (red) are highlighted.
