Mycoplasma columbinasale
(Jordan et al., 1982)
Etymology
Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; L. n. columbus – a pigeon, L. n. nasus – a nose, L. neut. suff. -ale – of, N.L. neut. adj. columbinasale – of the pigeon nose
Taxonomy
Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma columbinasale (Bovis cluster), closely related to Mycoplasma columbinum (16S rRNA gene sequence similarity – 96.61%) (Fig. 1)
Type strain
694T (pigeon, USA, ≤1964), (Fig. 2, 16S rRNA gene sequence)
Genomes
one completed (694T – USA) (NCBI Genome deposit per 11/05/2024)
Cell morphology
spherical – coccoid
Colony morphology
fried egg morphology (Fig. 3)
Metabolism
hydrolysis of arginine; non-fermentative, non-urea-hydrolyzing
Host
pigeon
Habitat
turbinates
Disease(s)
unknown, no disease reported
Pathogenicity
factors unknown
Epidemiology
less commonly isolated from rock pigeons than Mycoplasma columborale and Mycoplasma columbinum
Diagnosis
cultivation and species identification by MALDI-ToF MS, serology or genetically
Fig. 1. Maximum likelihood tree showing the phylogenetic position of Mycoplasma columbinasale 694T within the Bovis cluster of Mycoplasmataceae based on 16S rRNA gene sequences. 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)

Colonies of Mycoplasma columbinasale 694T on modified Hayflick’s agar after 4 days of incubation exhibiting fried egg morphology. Note, colour change of solid medium from ochre to reddish based on release of ammonia resulting from hydrolysis of arginine creating an alkaline pH. Bar, 1 mm.
