Abstract
27 patients, aged 19–23 yr, with symptomatic urinary tract infection or epididymitis due to Pseudomonas aeruginosa were treated with azlocillin. All Pseudomonas strains were sensitive to azlocillin. The microorganism was eradicated in 25/26 evaluable patients. 25/27 patients were clinically cured. Bacteriological relapse occurred in 11 patients. No serious drug reactions were noted.
