Mycoplasmatales

An order of gram-negative bacteria containing cells that are bounded by a three-layered membrane but do not possess a true cell wall. The minimal reproductive units are 0.2-0.3 mcm in diameter. Pathogenic and saprophytic species occur. These organisms reproduce through the breaking up of branched filaments into coccoid, filterable elementary bodies. The order includes the so-called pleuropneumonialike organisms , under organism (PPLO).
