Mycoplasma anserisalpingitidis
(Volokhov et al., 2020)
Etymology
Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; N.L. masc. n. anser – a goose, N.L. fem. n. salpingitis – inflammation of the oviduct, N.L. gen. n. anserisalpingitidis - of an inflamed oviduct of a goose
Taxonomy
Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma anserisalpingitidis (Synoviae cluster), closely related to Mycoplasma anatis (16S rRNA gene sequence similarity – 99.17%) (Fig. 1)
Type strain
1220T (goose, Hungary, ≤1984), (Fig. 2, 16S rRNA gene sequence)
Genomes
5 completed (1220T – Hungary, MYCAV 93 – Hungary, MYCAV 177 – Hungary, MYCAV 271 - Hungary, MA 271 – Hungary) (NCBI Genome deposit per 11/05/2024)
Cell morphology
spherical – coccoid
Colony morphology
fried egg morphology (Fig. 3)
Metabolism
fermentation of glucose and fructose; non-arginine-hydrolyzing, non-urea-hydrolyzing
Host
goose but have also been isolated from ducks
Habitat
cloaca, reproductive organs
Disease(s)
associated with inflammation of the cloaca and phallus, salpingitis, decreased egg production and embryo mortality
Pathogenicity
factors unknow
Epidemiology
probably worldwide occurrence in geese; transmission probably by the genital route, vertical transmission to eggs
Diagnosis
cultivation and species identification by MALDI-ToF MS, serology or genetically, PCR

The sequence of Mycoplasma hyopneumoniae JT was used as out-group (Hyopneumoniae 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)
