RESUMO
Mycoplasma granularum strains grew on a medium devoid of animal serum or of serum fractions containing sterols; all strains possessed properties, including carotenoid biosynthesis, similar to those described for M. laidlawii. Some common antigenic components were noted among M. granularum and M. laidlawii strains by indirect fluorescent-antibody tests. The growth of M. granularum strains was slightly inhibited by antiserum to M. laidlawii PG-8, and the electrophoretic patterns of cell proteins of the M. granularum strains showed a close resemblance to that of M. laidlawii. However, direct fluorescent-antibody procedures performed on colonies grown on a serum-free medium clearly distinguished M. granularum from M. laidlawii. The occurrence of nonsterol-requiring mycoplasmas, in addition to M. laidlawii, raises questions as to the taxonomy of M. granularum and of the saprophytic mycoplasmas in general.
