Mycoplasma alvi
(Gourlay et al., 1977)
Etymology
Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; L. n. alvus – bowel, L. gen. n. alvi – of the bowel
Taxonomy
Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma alvi (Pneumoniae cluster), closely related to Mycoplasma pirum (16S rRNA gene sequence similarity – 97.41%) (Fig. 1)

IlsleyT (cattle, UK, 1976), (Fig. 2, 16S rRNA gene sequence)
Genomes
one draft genome (IlsleyT – UK) (NCBI Genome deposits per 11/05/2024)
Cell morphology
flask- or club-shaped
Colony morphology
uncentered or fried-egg morphology (Fig. 3)
Metabolism
fermentation of glucose and hydrolysis of arginine; non-urea-hydrolyzing
Host
cattle
Habitat
intestinal tract
Disease(s)
unknown
Pathogenicity
probably a commensal
Epidemiology
unknown
Diagnosis
cultivation and species identification by MALDI-ToF MS, serology or genetically
Fig. 1. Maximum likelihood tree showing the phylogenetic position of Mycoplasma alvi IlsleyT within the Pneumoniae 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)
