Special Issue Information

Dear Colleagues,

The rapid global spread of antibiotic-resistant bacteria represents one of the most critical threats to public health in the 21st century. The diminishing efficacy of conventional antibiotics has created an urgent need for innovative and alternative therapeutic strategies to prevent and treat bacterial infections. Among these, bacteriophage therapy has re-emerged as a promising, targeted, and biologically precise approach to combat multidrug-resistant pathogens.

This Special Issue aims to provide a multidisciplinary platform for cutting-edge research and comprehensive reviews focusing on bacteriophage therapy and related phage-based approaches like the use of phage-derived enzymes of phage-antibiotic combinations.

Topics of interest include, but are not limited to, the following:

  • Isolation, characterization, and genomics of therapeutic bacteriophages;
  • Phage–host interactions and bacterial resistance mechanisms;
  • Phage-derived enzymes (endolysins, depolymerases);
  • Phage therapy in clinical, veterinary, and environmental settings;
  • Phage–antibiotic synergy and combination therapies;
  • Biofilm control using bacteriophages;
  • Engineering and synthetic biology approaches in phage therapy;
  • Delivery systems, formulation, and pharmacokinetics of phages;
  • Regulatory, ethical, and safety aspects of phage therapy;
  • Case studies and clinical trials involving phage-based treatments.

I look forward to your valuable contributions and to advancing this rapidly evolving field together.

Bacterial sexually transmitted and sexually associated infections remain a major global health concern, increasingly complicated by antimicrobial resistance and the limited effectiveness of existing therapies. In this context, bacteriophage-based and phage-derived approaches have re-emerged as potential alternative antibacterial strategies. This narrative review examines their applicability across key bacterial pathogens associated with sexually transmitted infections, including Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Treponema pallidum and biofilm-associated bacterial vaginosis, with a particular focus on pathogen-specific biological barriers. Available evidence indicates that the success of phage-based interventions is strongly dependent on factors such as intracellular localisation, structural characteristics of the bacterial envelope and the presence of polymicrobial biofilms. While phage-derived platforms, including endolysins, depolymerases and engineered phages, demonstrate antibacterial activity in experimental settings, their effectiveness is uneven across different pathogens. Biofilm-associated infections appear more accessible to these approaches, whereas intracellular and structurally atypical bacteria are currently considered more challenging targets based on available mechanistic and experimental evidence. These observations highlight the need for pathogen-specific engineering strategies and delivery systems. Overall, phage-based therapeutics in this field should be considered within a framework that integrates biological constraints with targeted antimicrobial design. Full article
