  • 🧍 Pittman et al. (1991) suggested the abbreviation "EPRZ" for this genus name but this does not appear to be of practical relevance any longer. Publication: Pittman KF, Walczak CA, Lock CM.

  • 🧍 Species of the genus Eperythrozoon are cell-wall-less uncultivated parasitic bacteria that attach to the surface of host erythrocytes. Phylogenetic analysis of 16S rRNA gene sequences shows that these haemotrophic bacteria are closely related to species in the genus Mycoplasma Nowak 1929 (Approved Lists 1980). To reflect their phylogenetic affiliation, Neimark et al. 2001 propose that Eperythrozoon suis and Eperythrozoon wenyonii be transferred to the genus Mycoplasma as "Candidatus Mycoplasma haemosuis" and "Candidatus Mycoplasma wenyonii", respectively. Publication: Neimark H, Johansson KE, Rikihisa Y, Tully JG. Proposal to transfer some members of the genera Haemobartonella and Eperythrozoon to the genus Mycoplasma with descriptions of 'Candidatus Mycoplasma haemofelis', 'Candidatus Mycoplasma haemomuris', 'Candidatus Mycoplasma haemosuis' and 'Candidatus Mycoplasma wenyonii'. Int J Syst Evol Microbiol 2001; 51:891-899.
  • 🧍 The proposal of Neimark et al. to reclassify Eperythrozoon suis and Eperythrozoon wenyonii as "Candidatus" is not acceptable; they would lose standing in nomenclature [1]! Later, "Candidatus Mycoplasma haemosuis" and "Candidatus Mycoplasma wenyonii" will be renamed Mycoplasma suis and Mycoplasma wenyonii, respectively [2]. Publication: Anonymous. Notification list.
