Evaluation of host immune responses to Mycobacteriophage Fionnbharth by route of delivery.

ABSTRACT: For much of the last decade, tuberculosis (TB) was the leading cause of mortality due to an infectious pathogen (Mycobacterium tuberculosis, M.tb). Approximately 1.3 million deaths in 2023 worldwide were attributed to TB disease. Focused intervention strategies to block transmission would significantly reduce the global health burden of TB. Mycobacteriophages (phages) are a sorely underutilized biologic therapy for the pathogen M.tb, and here we aimed to address outstanding questions about their utility for clinical applications. We aimed to determine the impact of repeated mucosal or intravenous (IV) delivery of representative anti-M.tb phage FionnbharthΔ45Δ47 (Fionnbharth) in a preclinical mouse model. In addition, we specifically sought to understand which route induced anti-phage antib
