The six recognised Ureaplasma species have a GC content of 27–30%, and a genome size ranging from 0.76 to 1.17 Mbase pairs, and cholesterol is required for growth. A defining characteristic of the genus is that they perform urea hydrolysis. Some strains originally classified as U. urealyticum should be treated as a new species, U. parvum.
U. urealyticum has been isolated in those with urogenital diseases. Infection can occur in extragenital sites.
