The bacteria of the genus Mycoplasma and its close relatives are largely characterized by the lack of a cell wall. Despite this, the shapes of these cells often conform to one of several possibilities with varying degrees of complexity. For example, the genus Spiroplasma have an elongated helical shape without the help of a rigid structure of cell envelope. These forms presumably can contribute to the ability of mycoplasmas to thrive in their respective environments. Mycoplasma pneumoniae cells are rounded and have an excellent point of extension, which is involved in adhesion to host cells, in moving along the solid surfaces and in cell division. Cells of M. pneumoniae are small and pleomorphic.
Mycoplasmas require sterols for the stability of their membrane plasmica, which is very unusual in bacteria. The sterols are purchased for the environment, usually as cholesterol from animal parasites. In general, possess a small genome 0,58-1,38 megabases, which implies a drastic decline in their ability to biosynthesis, which explains their reliance on a host. Besides using an alternative genetic code where the codon UGA encodes tryptophan aminoacid instead of the usual stop signal “a year.”
