Abstract Mycoplasma pneumoniae is a leading atypical cause of community-acquired pneumonia in children and adults, and the prevalence of resistance to macrolides, the recommended first-line agents, varies markedly by region. Since the fastidious growth of M. pneumoniae makes phenotypic antimicrobial susceptibility testing impractical for routine use, clinical microbiology laboratories have focused on 23S rRNA gene-targeted molecular detection. This mini-review examines

Abstract Background: Accurate diagnosis of vulvovaginal candidiasis (VVC) is challenging because of the limitations of conventional wet-mount microscopy, which requires a trained examiner and offers suboptimal sensitivity. This preliminary study evaluated the analytical

Abstract Background: The accurate laboratory-based detection of respiratory viruses, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is essential for effective patient management and infection control in the post–coronavirus disease 2019 era. In this study, the performance of the PowerChek Respiratory Virus Panels 1–4 assay (Kogene Biotech) in detecting non-SARS-CoV-2 respiratory viruses and SARS-CoV-2 was compared

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
