Area of Science:

  • Veterinary Microbiology
  • Bacteriology
  • Poultry Science

Background:

  • Campylobacter jejuni is a significant pathogen causing foodborne illness.
  • Controlling C. jejuni colonization in broilers is crucial for food safety.
  • Phage therapy offers a potential alternative to antibiotics for poultry health.

Purpose of the Study:

  • To evaluate the efficacy of phage therapy in controlling Campylobacter jejuni colonization in young broilers.
  • To assess phage therapy as both a preventive and therapeutic measure.
  • To determine the safety and impact of phage treatment on broiler health.

Main Methods:

  • Broilers were colonized with C. jejuni and treated with phages either preventively or therapeutically.
  • Bacterial (CFU) and phage (PFU) counts were enumerated in caecal content.

  • Phage treatment involved single or combined phage applications.
  • Control groups received no phage therapy.

    • Main Results:

    • Phage therapy significantly reduced C. jejuni colonization in both preventive and therapeutic groups.
    • Initial bacterial load reduction was observed, with sustained lower levels compared to controls.
    • Phage and bacterial counts showed inverse fluctuations, indicating dynamic interactions.
    • No adverse health effects were noted in broilers receiving phage treatment.

    Conclusions:

    • Phage therapy is a promising and safe alternative for reducing Campylobacter jejuni colonization in broilers.
    • Phage treatment can be effectively applied as both a preventive and therapeutic strategy.
    • Further research supports phage therapy for improving poultry health and food safety.
