Antimicrobial susceptibility of bacterial isolates associated with chronic prostatitis

Fifty-three strains were isolated from expressed prostatic secretion of patients suffering from chronic prostatitis, microscopically and biochemically identified. About 89% of the 53 strains were Gram- positive cocci, whereas 11% were Gram-negative rods. The susceptibilities of the isolates to 16 different antimicrobial agents were assessed by the disc-sensitivity test. This investigation showed that afloxacin [quinolone] and carpenicillin [beta-lactam] could be used as drugs of choice in treatment of chronic prostatitis due to Gram-positive and Gram-negative bacteria. For chronic prostatitis due to Gram-positive bacteria, erythromycin would be the best
