<unk>  is a small bacterium found in the class Mollicutes. It belongs to the genus Mycoplasma, a well-known group of obligate intracellular parasites that inhabit humans. It also is known to be an opportunistic pathogen in immunocompromised humans. As with other Mycoplasma species, M.<unk>  is not readily treated with many antibiotics due to its lack of a peptidoglycan cell wall. Therefore, this species is relevant to the medical field as physicians face the task of treating patients suffering from infections with this microbe. It is characterized by a small physical size (0.1 micrometer in diameter on average), a small genome size, and a limited metabolism. It is also known to frequently contaminate laboratory experiments. This bacteria is very similar physiologically and morphologically to its sister species within the genus Mycoplasma; however, its recent discovery leaves many questions still unanswered about this microbe.
