Abstract Fecal microbiota transplantation (FMT) involves the transfer of fecal microbiota from healthy donors to patients to rectify dysbiosis and restore the functionality of the gut microbiota to a healthy state. Donor selection is important to minimize the risk of FMT. Donor selection for FMT is primarily focused on screening for potential infections. A complete consensus on screening tests

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 Accurate identification of the Mycobacterium tuberculosis complex (MTBC) and nontuberculous mycobacteria (NTM) is crucial for effective patient management. With declining tuberculosis and rising NTM infections in South Korea, rapid diagnostics are essential. This review provides a comprehensive overview of current diagnostic methods for mycobacterial identification used in Korean clinical laboratories. The field has shifted from conventional methods, such as
