Based on the isolation source history, phenotypic, genotypic, and phylogenetic characteristics of these novel strains, we propose the name Acholeplasma equirhinis sp. nov. for Acholeplasma sp. isolated from the nasopharynx of a horse [the type strain is N93<sup>T</sup> (= DSM 106692<sup>T</sup> = ATCC TSD-139<sup>T</sup> = NCTC 14351<sup>T</sup>)], and the name Mycoplasma procyoni sp. nov. for the Mycoplasma sp. isolated from the oral cavity of a North American raccoon [the type strain is LR5794<sup>T</sup> (= DSM 106703<sup>T</sup> = ATCC TSD-141<sup>T</sup> = NCTC 14309<sup>T</sup>)].
Our results suggest that the strains isolated from southern sea otters represent a novel species of the genus Mycoplasma, for which the name Mycoplasma enhydrae sp. nov. is proposed; the type strain is 6243-11<sup>T</sup> (=DSM 106704<sup>T</sup>=ATCC TSD-140<sup>T</sup>).
