Mycoplasma hyopharyngis

(Erickson et al., 1986)

Etymology

Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; Gr. n. hus – a swine, N.L. n. pharynx – throat, N.L. gen. n. hyopharyngis – of the throat of a swine

The sequence of Mycoplasma synoviae WVU 1853^T was used as out-group (Synoviae 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)
