Ureaplasma urealyticumRANK: SpeciesTAXONOMY: Terrabacteria group -> Tenericutes -> Mollicutes -> Mycoplasmatales -> Mycoplasmataceae -> Ureaplasma -> Ureaplasma urealyticum OVERVIEW: The six recognised Ureaplasma species have a GC content of 2 7–30%, 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. This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072] |
