Determine the taxonomic relationships and phylogenetic position of Haemophilus vaginalis relative to established bacterial genera.
Evaluated 78 clinical isolates and reference strains using Adansonian numerical analysis, DNA-DNA hybridizations, electron microscopy, and cell envelope biochemical assays.
Tested genetic relatedness against reference strains of the genera Haemophilus, Pasteurella, and Streptococcus, as well as CDC group DF-1.
Numerical analysis showed that all 78 strains were related to one another at a similarity level exceeding 95%, with no distinct biovars or subspecies detected.
DNA-DNA hybridizations demonstrated no genetic homology between H. vaginalis and members of Haemophilus, Pasteurella, Streptococcus, or CDC DF-1.
Identification of laminated cell walls, acetic acid production as the primary fermentation product, and catalase- and oxidase-negative phenotypes defined the novel genus Gardnerella, with type species G. vaginalis.
