Abstract Background: Human metapneumovirus (hMPV) is a major cause of acute respiratory infections in children and adults worldwide; however, no antiviral therapies or vaccines are currently available. Therefore, rapid and reliable diagnostic tools are required to support timely patient management and control outbreaks. Methods: We retrospectively evaluated GenBody hMPV Ag Rapid Test results using 165 consecutive clinical samples collected from patients with suspected respiratory infections between May and August 2024. Specimens were

Abstract Background: Mycobacterium avium complex (MAC) is a major cause of pulmonary nontuberculous mycobacterial disease; however, treatment outcomes remain suboptimal. Phenotypic drug susceptibility testing (DST) is conditionally recommended; however, conventional broth microdilution is labor-intensive. The Sensititre SLOMYCO® panel offers a standardized platform for DST

Abstract Latent tuberculosis infection refers to a state in which an individual is infected with Mycobacterium tuberculosis but shows no clinical symptoms. The World Health Organization estimates that 23-25% of the global population has LTBI, which poses a significant public health challenge owing to the risk of progression to active TB. Diagnosis of LTBI involves tests, such as the tuberculin skin test

Abstract Mycobacterium tuberculosis (MTB) and nontuberculous mycobacteria (NTM) present distinct clinical and epidemiological challenges and thus require tailored genotyping approaches. MTB is a globally transmissible pathogen for which diagnostic and surveillance infrastructures are well defined, whereas NTM infections are environmentally acquired, taxonomically diverse, and increasingly prevalent among vulnerable populations. Molecular genotyping is indispensable for both pathogen groups, supporting outbreak investigation and drug resistance prediction for MTB and species-level identification and relapse-versusreinfection distinction

Abstract Background: Identifying Bacillus spp. and performing antimicrobial susceptibility testing (AST) is challenging because of their diversity and limited clinical laboratory resources. We investigated the isolation frequency and antimicrobial susceptibility of Bacillus spp. over a 4-year period. Methods: Bacillus isolates collected between 2020 and 2024 were identified using matrixassisted laser desorption ionization-time of flight mass spectrometry, and AST was performed using
