The class contains both pathogenic and commensal species found in plants and animals. They are the smallest known microorganisms (0.2 μm) able to replicate in culture media. For instance, the Mycoplasmapneumoniae genome is 816,394 base pairs, approximately one sixth that of the common bacterium Escherichia coli. Precursor substances (eg, peptides, native proteins, cholesterol) are required for growth in vitro.
