Ureaplasma urealyticum is a pathogenic ureolytic mollicute which colonizes the urogenital tracts of humans. A genetic polymorphism between the two biotypes of U. urealyticum at the level of the urease genes was found. The urease gene cluster from a biotype 1 representative of U. urealyticum (serotype I) was cloned and sequenced. Seven genes were found, with(More)
The high rate of evolution of mitochondrial DNA makes this molecule suitable for genealogical research on such closely related species as humans and apes. Because previous approaches failed to establish the branching order of the lineages leading to humans, gorillas, and chimpanzees, we compared human mitochondrial DNA to mitochondrial DNA from five species(More)
Mycoplasma penetrans is a mycoplasma with unique morphology, recently identified in urine samples collected from HIV-infected patients. This mycoplasma has been found to be statistically associated with HIV infection, and to be cytopathic in vitro. The dominant antigen recognized during natural and experimental infections is an abundant lipoprotein, P35,(More)
