Antibiotic susceptibility in prostate-derived Propionibacterium acnes isolates.

The aim of this study was to determine antibiotic susceptibility of Propionibacterium acnes isolates from prostate. Prostate-derived P. acnes isolates (n = 24, Umeå & Örebro, Sweden, 2007-2010) and a panel of control strains (n = 25, Sweden) collected from skin and deep infections were assessed for resistance to penicillin G, piperacillin-tazobactam, imipenem, gentamicin, azithromycin, erythromycin, vancomycin, ciprofloxacin, moxifloxacin, tetracycline, tigecycline, fusidic acid, clindamycin, rifampicin, linezolid, daptomycin, trimethoprim-sulfamethoxazole, and metronidazole.

5alpha-reductase 2 polymorphisms as risk factors in prostate cancer.

Prostate cancer is a significant cause of death in Western countries and is under the strong influence of androgens. The steroid 5alpha-reductase 2 catalyzes the metabolism of testosterone into the more potent androgen dihydrotestosterone in the prostate gland. The enzyme is a target in pharmacological treatment of benign prostatic hyperplasia using specific inhibitors such as finasteride.
