Overview

Ureaplasma urealyticum was previously classified into biovar 1 and biovar 2 which are now referred to as U. parvum and U. urealyticum respectively.[1]

Classification

Tiny (T)-strain Mycoplasma was ascribed to the genus and specie Ureaplasma urealyticum in 1974.[2][1] U. urealyticum was later subdivided into two biotypes consisting of 14 recognized serotypes:[1][3]

  • Biovar 1 or B ( parvo biovar): Ureaplasma urealyticum biovar 1 was later designated as a separate specie called U. parvum following phylogenetic analysis done in 1999. It has four serotypes (serotypes 1, 3, 6, and 14).
  • Biovar 2 or A (T960 biovar): Ureaplasma urealyticum biovar 2 strain (also known as T960 biovar) retained its designation as U. urealyticum, and it consists of the remaining ten serotypes.
