The role of chlamydiae in epididymitis.

In 21 men suffering from acute or chronic epididymitis who underwent scrotal surgical exploration, diagnostic microbiological studies consisting in cultures of the epididymal tissues and mid-stream urine specimens, as well as examination of the urethral swabs--before and after prostatic massage--were performed. Laboratory tests revealed that 55 per cent of the patients younger than 40 years were infected by Chlamydia trachomatis, and 36 per cent by urinary tract bacteria. On the other hand, in only 10 per cent of the patients older than 40 years the causative organisms were Chlamydiae, whereas in 70 per cent the common urinary tract bacteriae were the agents of epididymal infection. The aforementioned microbiological examinations were proved to be reliable in demonstrating the causative bacteria for epididymitis.
