Rezumat: The study of the pangenome of Bacillus cereus through the analysis of 135 complete and validated genomes provides insight into its genetic diversity and implications for food safety. The pangenome, composed of a core genome (shared by all strains) and an accessory genome (variable between strains), can be classified as open, demonstrating a high adaptive capacity due to the acquisition of genes through horizontal gene transfer. This analysis identifies key genes associated with virulence, such as those responsible for producing toxins (Nhe, Hbl, cereulide), spore formation, and biofilm production. These factors are fundamental for understanding the differential pathogenicity of strains and their persistence in food-related environments. Additionally, exclusive genes and those within the accessory genome reveal specific adaptations, such as resistance to extreme conditions or metabolic advantages for colonizing diverse niches. Phylogenomic analysis based on core genome genes enables the identification of clades and lineages associated with outbreaks of foodborne diseases. Moreover, the detection of antibiotic resistance genes and mobile genetic elements, such as plasmids and transposons, highlights the risk of resistance dissemination in food and clinical environments. These findings are essential for developing targeted control strategies, improving detection methods in the food industry, and mitigating risks associated with the contamination and transmission of B. cereus. The pangenomic approach integrates bioinformatics and microbiological analyses to advance the surveillance and control of this pathogen in the food chain, contributing to the protection of public health.
