    Pediatric nontuberculous mycobacterial infections often mimic other respiratory diseases, leading to frequent misdiagnosis.

  • 2

    The study analyzed five pediatric patients with confirmed NTM infections, focusing on host susceptibility and diagnostic methods.

  • 3

    Pathogenic species identified included Mycobacterium abscessus in four patients and Mycobacterium paragordonae in one.

  • 4

    Predisposing factors for NTM infections ranged from immunocompetence to congenital airway anomalies and systemic immunodeficiency.

  • 5

    Targeted next-generation sequencing (tNGS) proved valuable in diagnosing NTM species when conventional methods were inadequate.
