ORDER X. MYCOPLASMATALES FREUNDT, 1955.[1]
(Borrelomycetales Turner, Jour. Path, and Bact., 41, 1935, 25; Pleuropneumoniales Tulasne and Brisou, Ann. Inst. Past., 88, 1955, 237; Freundt, Internat. Bull, of Bact. Nomen. and Taxon., 5, 1955, 71; MolUcutales Edward, Internat. Bull, of Bact. Nomen. and Taxon., 5, 1955, 89.)
My.co.plas.ma.ta'les. M.L. neut.n. Mycoplasma type genus of the order; -ales ending to denote an order; M.L. fern. pi. n. Mycoplasmatales the Mycoplasma order.
Highly pleomorphic organisms which possess a peculiar mode of reproduction (according to some observers) characterized by the breaking up of filaments (with a more or less pronounced tendency to true branching) into coccoid, filterable elementary bodies. The cell bodies are soft and fragile; without special precautions they are often distorted or entirely destroyed in microscopical preparations. Non-motile. Typical endospores are never produced. Gram-negative. Growth occurs in agar media, although most of the species have exacting nutritional requirements. Pathogenic and saprophytic species occur.
