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
