The isolation of Trichomonas vaginalis has been declining steadily during the past decade. Particularly the recent five years have seen a statistically significant decrease as compared with more than a decade ago. The most important single factor in this decrease appears to be a declining frequency of Trichomonas vaginalis infections in the field of obstetrics and gynecology. Today, it appears that Trichomonas vaginalis is assuming less and less importance as a causative agent of nongonococcal urethritis.
