This research aims to improve the effectiveness of phage therapy against Pseudomonas aeruginosa in cystic fibrosis patients by studying biofilm adaptation.
Investigated adaptive evolution of Pbunavirus phage PE1 in biofilms from a cystic fibrosis-derived Pseudomonas aeruginosa isolate.
Conducted in vitro assays under CF lung environment conditions to assess phage efficacy.
Performed cryo-EM, LPS profiling, and adsorption assays to evaluate phage mutations and binding capabilities.
Biofilm-adapted PE1 mutants showed enhanced efficacy against Pseudomonas aeruginosa biofilms.
Increased recognition of diverse biofilm populations was linked to specific mutations in phage genes.
Identified critical genomic targets for engineering phages tailored for therapeutic use in cystic fibrosis.
