Species/Subspecies: Ureaplasma diversum
Category: In the normal flora
Etymology: Genus name: urea form.
Species epithet: diverse, which refers to the differens with respect to polypeptide content and G+C content inU. urealyticum.
Significance:  [Important]   
Taxonomy:
Phylum
Tenericutes
Class
Mollicutes
Order
Mycoplasmatales
Family

Genus
Ureaplasma
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.
Catalase/Oxidase:?/-
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.
Hosts: Cattle
Clinical Picture: Clear discharge, which later becomes milk-like and turbid.
16S rRNA Seq.:
Acc-noStrainNumber of NTOperon
D78650 A417T 1478  

Taxonomy/phylogeny:
 
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.
