 Project objective

Emergence of antimicrobial resistance (AMR) is a grand scientific challenge of our time that has killed more than 700,000 people worldwide. Phage therapy, a promising complement to antibiotics, utilizes viruses of bacteria (bacteriophages) or phage-derived inhibitors as natural ways to fight AMR. The main obstacles in the clinical application of phage-based AMR therapy are the limited number of phage isolates and the unknown molecular mechanisms of phage-delivered bactericidal action. Building on the recent advances of my group in high-throughput, culture-independent but host-targeted methodologies, PHARMS aims to deploy a revolutionary approach: to screen for all possible phages of a resistant bacterial isolate, characterize multiple lines of their bactericidal functions, and use this information for the design of a whole battery of phage-based therapies that employ multifaceted modes of action.

Using an interdisciplinary research plan, PHARMS will discover phage-specific bactericidal action modes at all possible levels ranging from nucleotide sequence and transcription to translation, in order to elucidate the molecular mechanisms driving phage-mediated inhibition of AMR Acinetobacter baumannii, Helicobacter pylori, & Haemophilus influenzae (WP1). These discoveries, together with novel synthetic biology tools, will enable us to engineer an array of phage vectors that mimic phage-deployed bactericidal modes discovered under WP1, including transport of alien genes to deliver bactericidal effects (WP2). PHARMS will provide molecular confirmation and in vitro & in vivo validation of the functions of phage-encoded bactericidal peptides and enzymes (WP3). By elucidating universal and specific mechanisms of phage-delivered inhibition of AMR pathogens, PHARMS is positioned to provide the rational framework for the design of novel therapeutic strategies aimed at treating common and life-threatening infectious diseases.
