Mycoplasmas have been isolated from patients with acquired immunodeficiency syndrome (AIDS) and they may contribute to the pathogenesis of this disease. We have isolated repeatedly a previously unknown mycoplasma from the urine of an HIV-positive male homosexual and, subsequently, from the urine of 5 HIV-positive patients with AIDS. The mycoplasma was not found in the urine of 98 healthy control subjects. The organism has an unusual tip-like structure with densely packed fine granules and metabolizes both glucose and arginine for growth. Antigenic and DNA analyses show the organism to be distinct from other known mycoplasmas. The mycoplasma displays in-vitro activities associated with virulence in vivo. In addition, electronmicroscopy shows that the mycoplasma can invade and attach to various human and animal cells. We are investigating whether the new mycoplasma has a role in human disease.
