T-strains of mycoplasma and nongonococcal urethritis.

Since the isolation by Dienes and Esdall (1937) of a strain of Mycoplasma from a patient with a Bartholin's gland abscess, numerous attempts have been made to provide definite proof of the aetiological role of Mycoplasma in urogenital tract infections, especially nongonococcal urethritis (NGU). Most of the earlier studies were concerned with Mycoplasma hominis, but it now appears that this species is a normal inhabitant of the male urethra and not a cause of NGU (Taylor-Robinson, Addey, Hare, Jones, and Dunlop, 1969).
