The success of phage therapy is affected by the method of treatment delivery. This study focused on comparing different phage delivery routes, specifically oral (phage-impregnated feed), intraperitoneal (IP), and bath (immersion), in treatment of induced motile septicemia (MAS). The efficacy of phage cocktail in treating MAS-infected through different delivery routes was assessed by challenging the fish with 100% lethal dose of and conducting a 15-day treatment regimen. Blood and kidney samples were analyzed for bacterial and phage concentrations. All routes exhibited reduction of disease symptoms, significant ( < 0.05) decrease in bacterial count, and increase in phage count. Notably, IP route showed significant activity in reducing bacterial load. Phage therapy through IP route is the most effective yet invasive in controlling MAS infection in . The efficacy of oral route depends on the fish's intake of feeds, whereas the bath route was the least effective.

Background: Phage therapy, a treatment utilizing bacteriophages to combat bacterial infections, is gaining attention as a promising alternative to antibiotics, particularly for managing antibiotic-resistant bacteria. This study aims to provide a comprehensive review of phage therapy by examining its safety, efficacy, influencing factors, future prospects, and regulatory considerations. The study also seeks to identify strategies for optimizing its application and to propose a systematic framework for its clinical implementation.

Influenza epidemics remain a global public health challenge. Vaccination with nucleic acid-based vaccines, which trigger strong cellular and humoral immune responses, represents a promising approach for preventing virus infection. However, its effectiveness relies on efficient delivery and an immunoadjuvant.

Vascular endothelial growth factor receptor-3 (VEGFR-3) plays an indispensable role in lymphangiogenesis. Previous findings suggest that blocking the VEGFR-3 signaling pathway can inhibit lymph node metastasis effectively, thus reducing the incidence of distant metastasis. The development of new VEGFR-3-targeting drugs for early detection and effective treatments is, therefore, urgently required.

Mirror-image proteins, composed of D-amino acids, are an attractive therapeutic modality, as they exhibit high metabolic stability and lack immunogenicity. Development of mirror-image binding proteins is achieved through chemical synthesis of D-target proteins, phage display library selection of L-binders and chemical synthesis of (mirror-image) D-binders that consequently bind the physiological L-targets. Monobodies are well-established synthetic (L-)binding proteins and their small size (~90 residues) and lack of endogenous cysteine residues make them particularly accessible to chemical synthesis.
