Mycoplasma tullyi

(Yavari et al., 2017)

Etymology

Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; N.L. masc. gen. n. tullyi – of Tully (referring to J.G. Tully)

Taxonomy

Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma tullyi (Pneumoniae cluster), closely related to Mycoplasma gallisepticum and Mycoplasma imitans (16S rRNA gene sequence similarity – 99.72%) (Fig. 1)

Type strain

56A97^T (Humboldt penguin – Spheniscus humboldti, UK, 1997), (Fig. 2, 16S rRNA gene sequence)

Genomes

one completed genome (56A97^T – UK) (NCBI Genome deposit per 11/05/2024)

Cell morphology

spherical – coccoid – flask-shaped

Colony morphology

fried egg morphology (Fig. 3)

Metabolism

fermentation of glucose; non-arginine-hydrolyzing, non-urea-hydrolyzing

Host

Humboldt penguin (Spheniscus humboldti)

Habitat

respiratory tract, although the type strain has been isolated from liver

Disease(s)

so far unknown

Pathogenicity

factors unknown

Epidemiology

unknown, isolated from zoo-kept Humboldt penguins in UK and recently in Austria

Diagnosis

cultivation and species identification by MALDI-ToF MS, serology or genetically
