Abstract
MYCOPLASMAS are a group of microorganisms which can grow on cell-free medium and which are characterized by pleomorphism, for they are bound by a triple layered unit membrane instead of a rigid cell wall. The smallest reproductive forms are about 100 to 150 nm in size. They are the smallest known free-living organisms comparable in size with the myxoviruses, to which they show some morphological resemblance. The largest mycoplasma cell can exceed 1,000 nm in size.
