To the Editor.— McChesney et al (226:37, 1973) reported the incidence of gonococcal urethritis in male college students with urethritis to be 8%. They contrasted their findings with those of Kraus and Volk, 1 who found that the number of cases of urethritis at their clinic was equally divided between nonspecific and gonococcal urethritis. As McChesney et al report urethritis in Caucasian college students and Kraus and Volk in middle-class patients, we would like to report briefly on the venereal-disease frequency in black male patients with urethritis at the Neighborhood Union Venereal Disease Clinic, Atlanta. Of 388 male blacks having urethritis, 259 (66.8%) received only a Gram-stain test of urethral exudate, 33 (8.5%) received only a culture test of urethral secretions onto a Thayer-Martin plate, 69 (16.7%) received both tests, and 27 (7.0%) received neither. The Figure presents the relative venereal-disease frequency in these patients with clinical urethritis. Fifty-six and
