Decoding Biothreats With FT‐ICR‐MS: Metabotyping of Bacillus cereus Spores Through Untargeted Metabolomics

Journal of Mass Spectrometry, Volume 61, Issue 7, July 2026.
ABSTRACT Genome sequencing is the gold standard for microbial identification. However, it fails to distinguish closely related species with overlapping genetic features. This is the case of Bacillus cereus and Bacillus cytotoxicus, two members of the B. cereus group with distinct pathogenic profiles. While B. cereus, a well‐known opportunistic pathogen
