Mycoplasma collis
(Hill, 1983)
Etymology
Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; L. n. collis – a hill, L. gen. n. collis – of a hill (alluding to the author’s name)
Taxonomy
Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma collis (Hyopneumoniae cluster), closely related to Mycoplasma neurolyticum (16S rRNA gene sequence similarity – 96.87%) (Fig. 1)
Type strain
58BT (rat, UK, 1974), (Fig. 2, 16S rRNA gene sequence)
Genomes
one draft genome (58BT – UK) (NCBI Genome deposit per 11/05/2024)
Cell morphology
spherical – coccoid
Colony morphology
fried egg morphology
Metabolism
fermentation of glucose, non-arginine-hydrolyzing, non-urea-hydrolyzing
Host
mice and rats
Habitat
eye, nasopharynx
Disease(s)
initially associated with conjunctivitis but no further reports since then
Pathogenicity
factors unknown
Epidemiology
unknown, once isolated from 2 rat and one mouse colony in the UK
Diagnosis
cultivation and species identification by MALDI-ToF MS, serology or genetically
Fig. 1. Maximum likelihood tree showing the phylogenetic position of Mycoplasma collis 58BT within the Hyopneumoniae 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)
