It is proposed as a replacement name for Eperythrozoon coccoides based on a 16S analysis which classified the organism as a Mycoplasma instead of a Rickettsia. The proposal of Mycoplasma coccoides is illegitimate because it contravenes: a) the rule that requires authors to provide evidence that the type strain has been deposited in two separate recognized culture collections in different countries (there is no existing type material and the original name E. coccoides predates the concept of candidates) b) rule 28(b) of the International Code of Nomenclature of Bacteria: it was published as a request for an opinion without which the name can not be validated. c)it eliminates a validly published name
