Bacteriophage are bacterial parasites,and the use of phage as therapeutics to treat bacterial infection effectually, particularly in an era where antibiotic resistance has become so problematic. Bacteriophagic therapy will educt positive effect in bacterial infection with further research of phage. The progress in research on antisepticize mechanism, advantage as therapeutics , research of treatment bacterial infection and research of phage lysins were reviewed in this article.%噬菌体是一类细菌依赖性病毒,可有效地治疗细菌性感染,尤其是大量耐药菌株的出现使抗生素对细菌病的治疗越来越棘手,噬菌体疗法将对细菌病的控制起更加积极的作用.作者就噬菌体抗菌机理、治疗优势、噬菌体治疗细菌感染的研究及噬菌体裂解素的研究进展进行综述.
