|Etymology:||Genus name: urea form.|
Species epithet: diverse, which refers to the differens with respect to polypeptide content and G+C content inU. urealyticum.
|Type Strain:||A417 = ATCC 43321 = NCTC 10182.|
|Macromorphology (smell):||Forms very small colonies (0,100-0,175 mm in diameter), which have to be observed with a microscope.|
|Micromorphology:||Non-motile coccoid cells (about 0.5 µm in diameter).|
|Gram +/Gram -:|
|Metabolism:||Energy is generated by hydrolysis of urea to CO2 and NH3.|
|Other Enzymes:||Urease +|
|Fermentation of carbohydrates:||Glocose -|
|Spec. Char.:||Lacks a cell wall. A pH of 6.0-6.5 is required for growth.|
|Disease:||Has been associated with bovine vulvitis, endometritis, salpingitis, spontaneous abortion and infertility.
|Clinical Picture:||Clear discharge, which later becomes milk-like and turbid.|
|16S rRNA Seq.:|
||Seven species have been described within the genus Ureaplasma. This genus forms a "sister lineage" to mycoplasmas within the so-called M. pneumoniae cluster. See phylogenetic tree (Fig. 209:1). Mycoplasmas within the M. pneumoniae cluster and the Ureaplasma cluster as well as the hemotropic mycoplasmas belong to the phylogenetic pneumoniae group.|
|Comment:||Belongs to the normal flora, but may cause opportunistic infections.|
