Abstract

belongs to the class Mollicutes and is the smallest prokaryote capable of independent replication. It was originally isolated from the urethras of two men with non-gonococcal urethritis (NGU). It has a number of characteristics which are similar to its genetically close relative, , which is an established pathogen of the respiratory tract. lacks a cell wall and has a characteristic pear / flask shape with a terminal tip organelle. This organelle enables to glide along and adhere to moist / mucous surfaces, including host cells. has minimal metabolism, and when compared to the other genital mycoplasmas, has the ability to metabolise glucose. The organism is the smallest self-replicating prokaryote with a genome of only 580 kb pairs and was the second bacterium to have its genome fully sequenced. Its DNA falls under the low G+C category and thus has a lower melting temperature during denaturation in polymerase chain reaction (PCR) assays. The target genes for PCR assays include MgPa, rRNA and gap. has several virulence factors that are responsible for its pathogenicity. These include the ability to adhere to host epithelial cells using the terminal tip organelle with its adhesins, the release of enzymes and the ability to evade the host immune response by antigenic variation.
