To ascertain anaerobic urinary tract infection, a total of 615 urine specimens from 97 male and 117 female patients were cultured. Most of them have chronic urological disease, such as cancer of the bladder, benign prostatic hypertrophy and urinary calculus. Urinary bacteriological exminations were investigated to serially dilute the urine specimens obtained by two methods. Clean midstream catch technique was applied for the samples of male subjects and sterile catheterization for famele.112 strains of anaerobes were recovered from 27 per cent of 214 patients (78 of 615 specimens). Peptococcus anaerobius and Peptococcus variabilis were most frequent and isolated 18 times and also 7 strains of Bacteroides fragilis could be found in this study. This result seems similar to that obtained for the anterior urethral flora by other investigators.Among 30 urine samples with anaerobes of more than 105 viable cells counts per ml., anaerobes were isolated in 5. There is less significnat association between viable cell count and pyuria when anaerobic bacteria were cultured in large quantities of mine sample than when aerobic bacteria were cultured in similar conditions.The bacterial count and species of yielded anaerobes from urine samples are not the decisive factor for diagnosing anaerobic urinary tract infection. Additional factors, such as clinical findings and predisposing or underlying conditions of the patient, must always be considered. Now criterion for diagnosis of anaerobic urinary tract infection sholud be established.
