Enterococcus faecium is a significant multidrug-resistant pathogen. Bacteriophage cocktails are being proposed to complement antibiotic therapy. After a screen of 8 E. faecium strains against 4 phages, 2 phages (113 and 9184) with the broadest host ranges were chosen for further experiments. Transmission electron microscopy, whole-genome sequencing, comparative genome analyses, and time-kill analyses were performed. Daptomycin (DAP) plus the phage cocktail (113 [myophage] and 9184 [siphopage]) showed bactericidal activity in most regimens, while DAP addition prevented phage 9184 resistance against daptomycin-nonsusceptible E. faecium.
屎肠球菌是一种重要的多药耐药病原体。噬菌体鸡尾酒被提议作为抗生素治疗的补充。在对 8 株屎肠球菌对抗 4 种噬菌体进行筛选后,选择了具有最广泛宿主范围的 2 种噬菌体(113 和 9184)进行进一步实验。进行了透射电子显微镜检查、全基因组测序、比较基因组分析和时间杀伤分析。在大多数方案中,万古霉素(DAP)加噬菌体鸡尾酒(113[myophage]和 9184[siphopage])显示出杀菌活性,而 DAP 的添加阻止了对万古霉素不敏感的屎肠球菌中噬菌体 9184 对万古霉素的耐药性。
