Ten T-mycoplasma strains isolated from the urine of male
students with nongonococcal urethritis were compared in immunodiffusion,
indirect hemagglutination (IHA), metabolic inhibition (MI),
and immunoelectrophoretic tests using antigens prepared from these
isolates and specific rabbit antisera. Immunodiffusion, MI, and IHA
tests revealed complex antigenic interrelationships among the
T-mycoplasmas, whereas immunoelectrophoretic...
