Candidatus Mycoplasma haematovis

(corrig. Hornok et al., 2009)

Etymology

Gr. n. mukes – fungus, Gr. neut. n. plasma – formed, N.L. neut. n. Mycoplasma – fungus form; Gr. neut. n. haema, haematos – blood, L. fem. n. ovis – a sheep, N.L. gen. n. haematovis – of sheep blood (corrected by Oren et al., 2020)
