We evaluated the Cutibacterium acnes prevalence in prostatic biopsies and characterized the strains at a molecular level. 18 out of 36 biopsies (50%) were sterile after seven days in culture. C. acnes was observed in only two biopsies. Its prevalence was low (5.6%). Finally, the molecular characterization revealed diverse clusters including phylotypes IA₁, IB and II.

法国一家医院前列腺组织活检中痤疮皮肤杆菌的患病率较低

我们评估了前列腺活检中痤疮皮肤杆菌的流行率，并在分子水平上对菌株进行了表征。在培养 7 天后，36 个活检中有 18 个 (50%) 无菌。仅在两次活组织检查中观察到痤疮丙酸杆菌。其患病率较低（5.6%）。最后，分子表征揭示了包括系统发育型IA ₁、IB 和II在内的不同簇。
