Mycoplasma anseris
(Bradbury et al., 1988)
Etymology
Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; L. n. anser – a goose, L. gen. n. anseris – of a goose
Taxonomy
Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma anseris (Hominis cluster), closely related to Mycoplasma cloacale (16S rRNA gene sequence similarity – 98.34%) (Fig. 1)
Type strain
1219T (gander, Hungary, ≤1987), (Fig. 2, 16S rRNA gene sequence)
Genomes
one completed (1219T – Hungary); one draft genome (again the type strain) (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
goose
Habitat
cloaca, phallus
Disease(s)
inflammation of cloaca and phallus; may also cause airsacculitis, peritonitis, embryo lethality
Pathogenicity
factors unknown
Epidemiology
worldwide occurrence in geese; transmission probably by the genital route
Diagnosis
cultivation and species identification by MALDI-ToF MS, serology or genetically; PCR
Fig. 1. Maximum likelihood tree showing the phylogenetic position of Mycoplasma anseris 1219T within the Hominis 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 anseris 1219T 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.
