Mycoplasma indiense
(Hill, 1993)
Etymology
Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; N.L. neut. adj. indiense – of India (referring to the country from which the infected primates originated)
Taxonomy
Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma indiense (Hominis cluster), closely related to Mycoplasma orale (16S rRNA gene sequence similarity – 99.17%) (Fig. 1)
Type strain
3TT (rhesus monkey – Macaca mulatta, India (3 days in UK), 1974-1975) (Fig. 2, 16S rRNA gene sequence)
Genomes
no genome published (per 11/05/2024)
Cell morphology
spherical – coccoid
Colony morphology
fried egg morphology (Fig. 3)
Metabolism
arginine hydrolysis; non-fermentative, non-urea-hydrolyzing
Host
rhesus monkey (Macaca mulatta), baboon (Papio anubis)
Habitat
throat
Disease(s)
unknown, considered to be a commensal
Pathogenicity
factors unknown
Epidemiology
unknown, once isolated from one rhesus monkey and one baboon
Diagnosis
cultivation and species identification by MALDI-ToF MS, serology or genetically
Fig. 1. Maximum likelihood tree showing the phylogenetic position of Mycoplasma indiense 3TT 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)
