Clinical Characteristics, Molecular Diagnosis, and Drug Resistance Profiles of Nontuberculous Mycobacteria Infections: A Retrospective Analysis Using PCR Melting Curve Technology. [PDF]

Clin Transl Sci
ABSTRACT Nontuberculous mycobacteria (NTM) are emerging global pathogens. This study aimed to analyze the clinical features, species distribution, and drug resistance profiles of NTM infections in a northern Chinese hospital. A retrospective cohort study included 1769 patients with suspected mycobacterial infection from August 2023 to July 2025.

Micro-Computed Tomography Based Whole Block Imaging of Asthma-Associated Airway Remodeling With Mycobacterium avium-Induced Cavity Formation: 3-Dimensional Nondestructive Analysis. [PDF]

Pathol Int
Subpleural cavities are characteristic of Mycobacterium avium infections, but the precise route of infection remains unclear. Using merged micro‐computed tomography of multiple formalin‐fixed paraffin‐embedded (FFPE) blocks (merged whole block imaging), we visualized a continuous airway path from the hilum to a subpleural cavity.
