Abstract

Two mycobacteriophages were administered intravenously to a male with treatment-refractory Mycobacterium abscessus pulmonary infection and severe cystic fibrosis lung disease. The phages were engineered to enhance their capacity to lyse M. abscessus and were selected specifically as the most effective against the subject's bacterial isolate. In the setting of compassionate use, the evidence of phage-induced lysis was observed using molecular and metabolic assays combined with clinical assessments. M. abscessus isolates pre and post-phage treatment demonstrated genetic stability, with a general decline in diversity and no increased resistance to phage or antibiotics. The anti-phage neutralizing antibody titers to one phage increased with time but did not prevent clinical improvement throughout the course of treatment. The subject received lung transplantation on day 379, and systematic culturing of the explanted lung did not detect M. abscessus. This study describes the course and associated markers of a successful phage treatment of M. abscessus in advanced lung disease.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Lysogeny and horizontal gene transfer pose theoretical risks, as some phages can integrate into bacterial genomes and potentially transfer antibiotic resistance or virulence genes.

    “Lysogeny and horizontal gene transfer pose theoretical risks, as some phages can integrate into bacterial genomes and potentially transfer antibiotic resistance or virulence genes.”

    From Phage therapy in oncology: opportunities for cancer prevention and treatment (2026) · cites this paper as [149]

    The Introduction states that most phages infecting M. abscessus are temperate and can integrate into bacterial genomes, supporting the lysogeny risk. The paper does not say that phages may transfer antibiotic-resistance or virulence genes through horizontal gene transfer. The Results instead report no viral-DNA incorporation in the isolates studied; that finding does not rule out a theoretical risk elsewhere. (LLM, conf=0.87)

  • Phages have been successfully used to treat chronic, drug-resistant infections of M. abscessus.

    “successfully used to treat chronic, drug-resistant infections of M. abscessus (177–179)”
  • Phages have been explored as diagnostic tools.

    “Phages have also been explored as diagnostic tools, and successfully used to treat chronic, drug-resistant infections of M. abscessus (177–179).”

    From Mycobacterium smegmatis: The Vanguard of Mycobacterial Research (2023) · cites this paper as [179]

    The Results section, “Identification of Phages Active Against M. abscessus” (page not provided), describes screening a patient’s bacterial isolate to select therapeutic phages. The Methods describe phage-susceptibility and antibody assays, but neither those passages nor the passages retrieved for diagnostic use say that phages were explored as diagnostic tools. (LLM, conf=0.74)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
