Mycoplasma bradburyae
(Ramírez et al., 2023)
Etymology
Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; NL. gen. n. bradburyae – named after Janet M. Bradbury, to honour her considerable contribution to mycoplasmology and taxonomy
Taxonomy
Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma bradburyae (Pneumoniae cluster), closely related to Mycoplasma gallisepticum (16S rRNA gene sequence similarity – 99.1 %) (Fig. 1)
Type strain
T158T (Yellow-legged gull – Larus michahellis, Spain, 2007), (Fig. 2, 16S rRNA gene sequence)
Genomes
2 completed (T158T – Spain; IZSVE97/66 – Italy); 5 draft genomes (NCBI Genome deposit per 11/05/2024)
Cell morphology
flask-shaped
Colony morphology
fried egg morphology (Fig. 3)
Metabolism
fermentation of glucose; non-arginine-hydrolyzing, non-urea-hydrolyzing
Host
sea birds (Yellow-legged gulls, a Kelp gull, an Italian Black-headed gull, and a Cory's shearwater)
Habitat
upper respiratory tract
Disease(s)
so far unknown
Pathogenicity
harbour cyotadherence- and motility-related proteins (MGC2, GapA, CrmA, VlhA)
Epidemiology
found in the tracheas of 4 seabird species
Diagnosis
cultivation and species identification by MALDI-ToF MS or genetically

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