The term "mycoplasma" is widely used to refer to any organism within the class Mollicutes, which is composed of eight genera (including Mycoplasma, Ureaplasma, Acholeplasma, Anaeroplasma, and Asteroloplasma). Over 200 named Mycoplasma species exist, and 13 Mycoplasma species, two Acholeplasma species, and two Ureaplasma species have been isolated from humans [1]. However, only six species, five of which inhabit the genitourinary tract, are established or presumed human pathogens; Mycoplasma pneumoniae is a respiratory tract pathogen [2]:

M. pneumoniae

Mycoplasma hominis

Mycoplasma genitalium

Mycoplasma fermentans (incognitus strain)
