Abstract Background: Monophasic Salmonella enterica serovar Typhimurium variants, particularly the serotype I 4,[5],12:i:-, have globally emerged as important foodborne pathogens associated with multidrug resistance. However, their molecular epidemiology and clonal distribution in South Korea remain unclear. This study investigated the distribution, clonal characteristics, and antimicrobial resistance profiles of S.

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
