Abstract

The 16S rRNA gene of Eperythrozoon (Haemobartonella) wenyonii, a wall-less hemotrophic prokaryote currently classified as a rickettsia, was sequenced to determine the relationship of this organism to other wall-less prokaryotes. Comparison to the GenBank data base showed that this hemotrophic organism is a Mycoplasma (family Mollicutes). Phylogenetic analysis of 16S rRNA genes indicated that this and other recently sequenced 16S rRNA genes of hemotrophic bacteria form a new, separate branch which shares a node in common with the pneumoniae group of mycoplasmas. This result will require that Eperythrozoon wenyonii be reclassified as a Mycoplasma. A main point of this study is that this and related hemotrophic bacteria represent an entirely new group of pathogens among the mycoplasmas.
