The new species differs from Ureaplasma urealyticum serologically and on the basis of the guanine-plus-cytosine content of its deoxyribonucleic acid and its protein composition as determined by polyacrylamide gel electrophoresis. The species is serologically heterogeneous, the member strains apparently belonging to one of three serological clusters or groups. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-32-4-446
