Exposure assessment suggests some cytotoxic Bacillus cereus group genotypes can grow over 3 logs in HTST milk throughout the shelf life at temperature abuse conditions

This study develops an exposure assessment model to predict B. cereus group growth in HTST milk under temperature abuse conditions, showing some genotypes can reach 105 CFU/mL by day 35 of storage.

A community-curated, global atlas of Bacillus cereus sensu lato genomes for epidemiological surveillance

The paper develops BTyperDB, a global atlas of Bacillus cereus sensu lato genomes, to improve pathogen surveillance and identify emerging lineages.

Genus-Wide Genomic Characterization of Macrococcus: Insights into Evolution, Population Structure, and Functional Potential

This study analyzes 110 Macrococcus genomes to explore their evolution, population structure, and functional potential, focusing on antimicrobial resistance and virulence.

More than mcr: Canonical Plasmid- and Transposon-Encoded Mobilized Colistin Resistance (mcr) Genes Represent a Subset of Phosphoethanolamine Transferases

This study identifies and analyzes mcr-like genes, showing they are closely related to intrinsic lipid modification enzymes and evolve through positive selection and genomic context changes.

A multidrug-resistant Salmonella enterica Typhimurium DT104 complex lineage circulating among humans and cattle in the United States lost the ability to produce pertussis-like toxin ArtAB

The paper identifies a multidrug-resistant Salmonella DT104 lineage lacking the ArtAB toxin, circulating in humans and cattle in the U.S., and shows it lost these genes around 1985-1987.

Genomic surveillance of Bacillus cereus sensu lato strains isolated from meat and poultry products in South Africa enables inter- and intra-national surveillance and source tracking

This study uses whole-genome sequencing to analyze Bacillus cereus s.l. strains from meat products in South Africa, showing their potential for intra- and inter-national spread through the food supply chain.

Monitoring the Antimicrobial Resistance Dynamics of Salmonella enterica in Healthy Dairy Cattle Populations at the Individual Farm Level Using Whole-Genome Sequencing

This study uses whole-genome sequencing to analyze Salmonella strains from dairy cattle farms, revealing AMR dynamics and evaluating in silico tools for serotyping and resistance detection.

Genomic characterization of endemic and ecdemic non-typhoidal Salmonella enterica lineages circulating among animals and animal products in South Africa

This study uses whole-genome sequencing to analyze non-typhoidal Salmonella enterica strains from animals and animal products in South Africa, identifying endemic and emerging lineages and antimicrobial resistance patterns.

Cereulide synthetase acquisition and loss events within the evolutionary history of Group III Bacillus cereus sensu lato facilitate the transition between emetic and diarrheal foodborne pathogen

This study uses phylogenomic analysis to show that cereulide synthetase acquisition and loss events in Group III B. cereus s.l. allow populations to transition between emetic and diarrheal pathogen roles.

No Assembly Required: Using BTyper3 to Assess the Congruency of a Proposed Taxonomic Framework for the Bacillus cereus group with Historical Typing Methods

The paper evaluates the congruency of a new taxonomic framework for B. cereus group with historical methods using MLST, panC, and WGS data, showing compatibility and providing tools for classification.

Comparative genomics reveals different population structures associated with host and geographic origin in antimicrobial-resistant Salmonella enterica

This study uses comparative genomics to analyze AMR Salmonella enterica isolates from bovine and human hosts, revealing distinct genetic profiles linked to host and geographic origin.

Identification of novel mobilized colistin resistance gene mcr-9 in a multidrug-resistant, colistin-susceptible Salmonella enterica serotype Typhimurium isolate using a combination of high-throughput, in silico screening and functional analysis

The paper identifies a novel mcr-9 gene in a multidrug-resistant Salmonella isolate using in silico screening and functional analysis, showing it confers colistin resistance in E. coli.

Bacillus clarus sp. nov. is a new Bacillus cereus group species isolated from soil

The paper identifies a new Bacillus species, Bacillus clarus, based on genomic and phenotypic analysis of an isolate from soil.

Characterization of emetic and diarrheal Bacillus cereus strains from a 2016 foodborne outbreak using whole-genome sequencing: addressing the microbiological, epidemiological, and bioinformatic challenges
