Phage therapy for multidrug-resistant pulmonary infections: bridging precision matching, lung delivery, host immunity, and clinical translation.
Review in Frontiers in cellular and infection microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Chronic pulmonary infections caused by multidrug-resistant (MDR) bacteria are a growing global health problem, and the declining effectiveness of conventional antibiotics increases the need for alternative antimicrobial strategies. Unlike broad-spectrum antibiotics, bacteriophages are highly specific, and their use therefore offers not only antibacterial activity but also the possibility of reshaping the airway microbial ecosystem in a targeted manner. In this review, we reframe phage therapy as a precision microbiome-modulating strategy for chronic pulmonary infections. We first review precision pathogen identification and phage-host matching, then discuss formulation engineering for pulmonary delivery, and then examine the interactions between phages and host immune barriers. We further analyze how phage therapy may selectively deplete MDR pathogens while sparing the commensal microbiota and how it may remodel the airway microbial ecosystem, and we critically evaluate the clinical evidence, distinguishing preclinical data, case-based evidence, observational studies, and controlled trials. By integrating these dimensions, we identify the main scientific and technical challenges and evidence gaps that currently limit clinical implementation, and we discuss strategies that could support the development of safe, effective, and clinically applicable phage-based therapies for chronic pulmonary infections.
