  • Identification of potential targets for drug development.

    • Main Results:

    • Virulence factors are critical for bacterial adherence, invasion, and host defense evasion.
    • Targeting these factors can disarm pathogens without necessarily killing them.
    • This approach offers a broad applicability across different bacterial species.

    Conclusions:

    • Targeting bacterial virulence is a viable strategy to combat untreatable infections.
    • Further research into virulence factors will facilitate the development of new antimicrobial agents.
    • This approach holds promise for addressing the challenge of antibiotic resistance.
