Ecology of prophage-like elements in Bacillus subtilis at global and local geographical scale

This study investigates prophage-like elements in Bacillus subtilis across global and local scales, revealing their diversity, integration patterns, and potential impact on host evolution and physiology.

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.

Context matters: environmental microbiota of ice cream processing facilities affects the inhibitory performance of two lactic acid bacteria against Listeria monocytogenes

The paper tests how microbiota from ice cream processing facilities affects the antilisterial activity of two lactic acid bacteria strains against L. monocytogenes.

Conditional forest models built using metagenomic data could accurately predict Salmonella contamination in Northeastern streams

This paper uses metagenomic data from Northeastern streams to predict Salmonella contamination using conditional forest models, finding Aeromonas and Tabrizicola as key indicators.

Short term tomato consumption alters the pig gut microbiome towards a more favorable profile

This study shows that short-term tomato consumption in piglets increases the ratio of Bacteroidota to Bacillota and alpha-diversity, suggesting a beneficial shift in the gut microbiome.

Comparative analysis of Bacillus cereus group isolates' resistance using disk diffusion and broth microdilution and the correlation between resistance phenotypes and genotypes

This study compares phenotypic antibiotic resistance in Bacillus cereus group isolates using disk diffusion and broth microdilution, finding discrepancies in resistance interpretation and poor correlation between resistance genes and phenotypes.

Kin discrimination promotes horizontal gene transfer between unrelated strains in Bacillus subtilis

This study shows that kin discrimination in B. subtilis promotes horizontal gene transfer between distantly related strains by inducing competence in recipients through a stress response.

Dynamic Laser Speckle Imaging meets Machine Learning to enable Rapid Antibacterial Susceptibility Testing (DyRAST)

DyRAST uses dynamic laser speckle imaging and machine learning to rapidly predict antibiotic minimum inhibitory concentrations in E. coli within 60 minutes.

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.

Biotransformation of D-xylose to D-xylonic acid coupled to medium chain length polyhydroxyalkanoate production in cellobiose-grown Pseudomonas putida EM42.

This study demonstrates Pseudomonas putida EM42's ability to co-produce D-xylonic acid and medium chain length polyhydroxyalkanoates from D-xylose and D-cellobiose.

Proposal of a taxonomic nomenclature for the Bacillus cereus group which reconciles genomic definitions of bacterial species with clinical and industrial phenotypes

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

This paper uses whole-genome sequencing to characterize B. cereus group strains from a foodborne outbreak, identifying emetic and diarrheal isolates and their genetic relationships.
