Mycoplasma iguanae
(Brown et al., 2006)
Etymology
Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; N.L. gen. n. iguanae – of the iguana lizard
Taxonomy
Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma iguanae (Hyopneumoniae cluster), related to Mycoplasma lagogenitalium (16S rRNA gene sequence similarity – 93.64%) (Fig. 1)
Type strain
2327T (green iguana – Iguana iguana, USA, ≤2006) (Fig. 2, 16S rRNA gene sequence)
Genomes
one completed genome (2327T – USA) (NCBI Genome deposits per 11/05/2024)
Cell morphology
spherical – coccoid, pleomorphic
Colony morphology
umbonate with small, sectored centers (Fig. 3)
Metabolism
fermentation of glucose; non-arginine-hydrolyzing, non-urea-hydrolyzing; temperature optimum for growth is 30°C
Host
green iguana (Iguana iguana)
Habitat
unknown, isolated from vertebral abscesses present in two feral green iguanas
Disease(s)
associated with spinal lesions
Pathogenicity
factors unknown
Epidemiology
unknown, once isolated from 2 feral green iguanas from southern Florida, USA
Diagnosis
cultivation (at 30°C) and species identification by MALDI-ToF MS, serology or genetically

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)
