Anaerobes and carcinoma of the prostate

Anaerobic bacteria are present in healthy people on all mucosal surfaces and can be isolated from the urine and periurethral region. Anaerobes may be associated with pyelonephritis, urethritis, renal abscess, prostatitis, and septicaemia. Carcinomas of the bronchus, colon, and uterus are associated with anaerobic infections. The recorded incidence of prostatic carcinoma in men aged over 50 is between 14 and 46%. The authors tested the hypothesis that anaerobes are associated with prostatic carcinoma.
