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

Zaradi2(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 1853was used as out-group (Synoviae cluster). Numbers at nodes represent bootstrap confidence values (1000 replications). Only values > 80% are shown.
