Phage therapy is recognized as a promising alternative to antibiotics in treating pulmonary bacterial infections, however, its use has not been reported for treating secondary bacterial infections during virus pandemics such as coronavirus disease 2019 (COVID-19). We enrolled 4 patients hospitalized with critical COVID-19 and pulmonary carbapenem-resistant (CRAB) infections to compassionate phage therapy (at 2 successive doses of 10 plaque-forming unit phages). All patients in our COVID-19-specific intensive care unit (ICU) with CRAB positive in bronchoalveolar lavage fluid or sputum samples were eligible for study inclusion if antibiotic treatment failed to eradicate their CRAB infections. While phage susceptibility testing revealed an identical profile of CRAB strains from these patients, treatment with a pre-optimized 2-phage cocktail was associated with reduced CRAB burdens. Our results suggest the potential of phages on rapid responses to secondary CRAB outbreak in COVID-19 patients.

Bacteriophages hold promise for combating pathogenic bacteria in the human intestinal tract, but their therapeutic potential is limited by harsh stomach conditions, including low pH and digestive enzymes. This study aimed to develop a natural protective mechanism for orally administering phages to treat gastric infections caused by Klebsiella aerogenes. Results revealed that free phages became inactive at pH 3 without protective measures.

Antimicrobial resistance (AMR) has become an increasingly severe threat to global health, and AMR-associated infection is one of the leading causes of death around the world. Due to the long turnaround time and the limited flexibility and availability of current antimicrobial susceptibility testing (AST) methods, a large portion of patients with bacterial infections are still treated empirically, increasing the risk of mistreatment. To address the demand for precision treatment of bacterial infections, we developed a nano-dilution SlipChip (nd-SlipChip)-based systematic evaluation method, which facilitates rapid, logic feedback for the assessment of antibiotics, antibiotic combinations, and phage therapy.

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.

() is a Gram-negative, spiral-shaped bacterium that colonizes the gastric epithelium and is associated with a range of gastrointestinal disorders, exhibiting a global prevalence of approximately 50%. Despite the availability of treatment options, frequently reemerges and demonstrates increasing antibiotic resistance, which diminishes the efficacy of conventional therapies. Consequently, it is imperative to explore non-antibiotic treatment alternatives to mitigate the inappropriate use of antibiotics.

Identifying phage-host interactions (PHIs) is a crucial step in developing phage therapy, which is the promising solution to addressing the issue of antibiotic resistance in superbugs. However, the lifestyle of phages, which strongly depends on their host for life activities, limits their cultivability, making the study of predicting PHIs time-consuming and labor-intensive for traditional wet lab experiments. Although many deep learning (DL) approaches have been applied to PHIs prediction, most DL methods are predominantly based on sequence information, failing to comprehensively model the intricate relationships within PHIs.
