Isolation of diphtheroids from non-gonococcal urethritis.

Abstract
Through the use of special techniques, diphtheroids were isolated from the urethra in 94% of male patients with non-gonococcal urethritis and in 11% of controls by passage in the yolk sac of fertile eggs. Diphtheroids may be associated with non-gonorrheal urethritis since they disappear on clinical cure, return on relapse and continue to be present in patients who do not respond to treatment.
