Mycoplasma wenyonii

(Adler & Ellenbogen, 1934; Neimark et al., 2002)

Etymology

Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; N.L. masc. gen. n. wenyonii – of Wenyon (referring to C.M. Wenyon)

Taxonomy

Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma wenyonii (Hemoplasma cluster, Eperythrozoon subcluster), closely related to Candidatus Mycoplasma haemocervae (16S rRNA gene sequence similarity – 96.33%) (Fig. 1)

Type strain

not available, not cultivated in/on cell free media (Fig. 2, 16S rRNA gene sequence of isolate Massachusetts)

Genomes

one completed (isolate Massachusetts – USA); one draft genome (NCBI Genome deposit per 11/05/2024)

Cell morphology

spherical – coccoid

Colony morphology

not cultivated on cell-free medium

Metabolism

not assessed, probably fermentation of glucose, assimilation of glycerol; non-arginine-hydrolyzing, non-urea-hydrolyzing

Host

cattle

Habitat

blood

Disease(s)

hemolytic anemia, limb edema, often asymptomatic

Pathogenicity

factors unknown

Epidemiology

worldwide occurrence; transmission via blood-feeding arthropod vectors

Diagnosis

PCR
