Mycoplasma tauri
(Spergser et al., 2022)
Etymology
Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; L. gen. n. tauri – of a bull
Taxonomy
Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma tauri (Bovis cluster), closely related to Mycoplasma primatum (16S rRNA gene sequence similarity – 97.58%) (Fig. 1)
Type strain
Zaradi2T (bull, Austria, 2006), (Fig. 2, 16S rRNA gene sequence)
Genomes
one completed (Zaradi2T – Austria); 6 draft genomes (NCBI Genome deposit per 11/05/2024)
Cell morphology
spherical – coccoid
Colony morphology
fried egg morphology (Fig. 3)
Metabolism
oxidation of organic acids (pyruvate, lactate); non-fermentative, non-arginine-hydrolyzing, non-urea-hydrolyzing
Host
cattle
Habitat
bovine genital tract
Disease(s)
considered part of the autochthonous microbiota of the lower genital tract, occasionally isolated from clinical cases, e.g., from testis displaying orchitis and from uterine swabs taken from cows exhibiting endometritis
Pathogenicity
pathogenicity factors unknown
Epidemiology
presumably worldwide occurrence, has been found in cattle from Austria, Germany, Slovakia, and Australia
Diagnosis
cultivation and species identification by MALDI-ToF MS, PCR

The sequence of Mycoplasma synoviae WVU 1853T 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)
