Abstract
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, wholegenome 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.
