This article discusses the development of methods to predict the effectiveness of bacteriophage therapy for surgical site infections after cardiovascular surgery. Surgical site infections are a concern, especially when they involve multidrug-resistant pathogens. Phages, which are viruses that can target and kill bacteria, are being explored as an alternative or supplement to antibiotics. The study describes the development of gelatin-based scaffolds to simulate the conditions in treated tissues and evaluate the protective effect and adhesion rate of bacteriophages. These methods aim to optimize phage therapy regimens and establish evidence-based guidelines for their use in cardiovascular surgery. [Extracted from the article]
