1. Genetic relationships of Haemophilus and Aggregatibacter species, using Escherichia coli as an outgroup.
Genetic relationships of Haemophilus and Aggregatibacter species, using Escherichia coli as an outgroup. Concatenated sequences of near-full-length 16S rRNA genes (1,361 to 1,364 nt) plus fragments of three housekeeping genes, infB, pgi, and recA (1,293 nt), were compared by the neighbor-joining method (36, 99). The dendrogram is based on type strains of validated species, except for H. ducreyi, where strain 35000HP was used (GenBank accession no. AE017143). Strain CCUG represents the not validly named species H. intermedius. Bar, 2 substitutions per 100 nucleotides.
