Rebekah Dedrick (University of Pittsburgh) and colleagues published a new paper in Nature Medicine on how antibody-mediated neutralization limited phage treatment of a pulmonary M. abscessus infection. They used the same phages that worked well in their well-known 2019 UK patient case, but they didn't work well in this new patient, which led to important insights into the immune system's impact on phage therapy.
