Lung Biopsies in Patients Referred for Allogeneic Hematopoietic Cell Transplantation: Diagnostic Accuracy, Diagnostic Yield, and Clinical Utility

Transplant Infectious Disease, Volume 28, Issue 3, May/June 2026.
Among patients referred for allogeneic hematopoietic cell transplantation with pulmonary opacities, lung biopsy provided a diagnosis in 72% of procedures and altered management in 51%. Despite a 7% major complication rate, lung biopsy frequently clarified noninfectious etiologies when bronchoscopy was inconclusive.

NCY‐1 β‐Lactamase Activity Correlates With Antimicrobial Susceptibility of a Clinical Strain of Nocardia cyriacigeorgica

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
This study shows a strong correlation between the β‐lactam susceptibility profile of a clinical isolate of Nocardia cyriacigeorgica and the activity of its β‐lactamase, NCY‐1. Inhibitors of NCY‐1 reduce the minimum inhibitory concentration of amoxicillin.

Emerging role of metagenomic next‐generation sequencing in infectious disease diagnostics: Clinical integration and future directions

mLife, Volume 5, Issue 2, Page 148-163, April 2026.
Abstract Infectious disease diagnostics has been transformed by metagenomic next‐generation sequencing (mNGS), an unbiased approach that detects bacteria, viruses, fungi, and parasites in a single assay. By sequencing all nucleic acids in a sample, mNGS overcomes the narrow detection scope and slow turnaround of conventional tests, substantially ...
