曾经被忽视为人类肠道微生物区系被动旁观者的新证据,正在揭示肠球菌及其噬菌体(噬菌体)在塑造人类健康方面的重要性。噬菌体是肠球菌的天然捕食者,代表了一种窄谱、精确的靶向方式,用于根除微生物区系或受感染组织中的问题肠球菌。噬菌体感染后对肠球菌噬菌体受体、吸收因子和转录反应的鉴定揭示了一种复杂的捕食-被捕食关系,该关系调节了肠球菌细胞表面的结构、对抗生素的敏感性以及对宿主相关环境的适应。考虑到制药行业当代抗生素发现管道的枯竭和多重耐药肠球菌的持续出现,肠球菌噬菌体可能是真正的治疗药物。我们重点介绍了肠球菌噬菌体生物学的最新进展,重点是最近在潜在治疗应用方面的突破,这些应用将肠球菌噬菌体置于下一代生物制品的前沿。
Once overlooked as passive bystanders of the human intestinal microbiota, new evidence is shedding light on the importance of enterococci and their bacteriophages (phages) in shaping human health. Natural predators of enterococci, phages represent a narrow spectrum, precision targeting modality for eradication of problematic enterococci within the microbiota or infected tissue. The identification of enterococcal phage receptors, absorption factors, and transcriptional responses following phage infection reveal a complex predator-prey relationship that modulates enterococcal cell surface architecture, susceptibility to antibiotics, and adaptation to host associated environments. Considering the dry up of contemporary antibiotic discovery pipelines in the pharmaceutical industry and a continued emergence of multidrug resistant enterococci, enterococcal phages may serve as bonafide therapeutics. We highlight current advances in enterococcal phage biology with emphasis on recent breakthroughs in potential therapeutic applications that place enterococcal phages at the forefront of next-generation biologics.
