Ureaplasma urealyticum is a bacterium belonging to the genus Ureaplasma and the family Mycoplasmataceae[1] in the order Mycoplasmatales. This family consists of the genera Mycoplasma and Ureaplasma. Its type strain is T960.


The six recognised Ureaplasma species have a GC content of 27 to 30 percent and a genome size ranging from 0.76 to 1.17 million base pairs, and cholesterol is required for growth.[2] 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.[3]

Clinical relevance[edit]

U. urealyticum can cause urethritis and bacterial vaginosis.[4] It has also has been linked to infertility.[4] Infection can occur in extragenital sites.[3]
