Implication

Comparative genomic analysis uncovers that higher antiphage system counts drive phage resistance in Pseudomonas aeruginosa, suggesting key targets to optimize phage therapy.

Key Points

To determine the distribution and diversity of antiphage systems in clinical isolates of Pseudomonas aeruginosa and evaluate their relationship with bacterial resistance to phages.
Screened genomes from a diverse panel of Pseudomonas aeruginosa clinical isolates for putative antiphage defense systems using the PADLOC web-server tool.
Assessed empirical bacterial susceptibility profiles by testing host range against a panel of 70 distinct bacteriophages.
Demonstrated that higher numbers of encoded antiphage defense systems in bacterial genomes correlate positively with existing phage resistance.
Identified specific antiphage defense system types that appear with greater prevalence in highly phage-resistant Pseudomonas aeruginosa strains.
