Mycoplasma insons

(May et al., 2007)

Etymology

Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; L. neut. adj. insons – innocent (referring to the apparent commensalism of the organism)

Taxonomy

Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma insons (not part of a cluster), effectively but not validly published, related to Mycoplasma fastidiosum (16S rRNA gene sequence similarity – 95.42%) (Fig. 1)

Type strain

I17P1^T (green iguana – Iguana iguana, El Salvador, ≤2007), (Fig. 2, 16S rRNA gene sequence)

Genomes

no genome published (per 11/05/2024)

Cell morphology

twisted rods, pleomorphic

Colony morphology

umbonate

Metabolism

fermentation of glucose; non-arginine-hydrolyzing, non-urea-hydrolyzing; temperature optimum for growth is 30°C

Host

green iguana (Iguana iguana)

Habitat

upper respiratory tract

Disease(s)

unknown, considered to be a commensal so far

Pathogenicity

factors unknown

Epidemiology

unknown, once isolated from seven green iguanas from El Salvador

Diagnosis

cultivation (at 30°C) and species identification by MALDI-ToF MS or genetically
