Mycoplasma coccoides

(Schilling, 1928; Neimark et al., 2005)

Etymology

Gr. n. mukes – fungus, Gr. neut. n. plasma – anything formed, N.L. neut. n. Mycoplasma – fungus form; N.L. masc. n. coccus – coccus, L. suff. -oides – similar, N.L. neut. adj. coccoides – coccus-shaped

Taxonomy

Mycoplasmatales – Mycoplasmataceae – Mycoplasma – Mycoplasma coccoides (Hemoplasma cluster, Haemobartonella subcluster!), related to Candidatus Mycoplasma turicense (16S rRNA gene sequence similarity – 93.05 %) (Fig. 1)

Cell morphology

spherical – coccoid

Colony morphology

not cultured on a cell free medium

Metabolism

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

Host

mice

Habitat

blood

Disease(s)

hemolytic anemia but often asymptomatic

Pathogenicity

factors unkown
