Mycoplasma oxoniense
(corrig. Hill, 1991)
Etymology
Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; N.L. adj. oxoniense – of Oxon (abbreviation of Oxfordshire, where the organism was first isolated)

Fig. 1. Maximum likelihood tree showing the phylogenetic position of Mycoplasma oxoniensis 128T within the Synoviae cluster of Mycoplasmataceae based on 16S rRNA gene sequences. The sequence of Mycoplasma hyopneumoniae JT was used as out-group (Hyopneumoniae cluster). Numbers at nodes represent bootstrap confidence values (1000 replications). Only values > 80% are shown. Bar, number of substitutions per nucleotide position. Credits: Joachim Spergser (Vetmeduni Vienna)
