Spatial and temporal coordination of Duox/TrpA1/Dh31 and IMD pathways is required for the efficient elimination of pathogenic bacteria in the intestine of Drosophila larvae

Multi-omics analyses from a single sample: Prior metabolite extraction does not alter the 16S rRNA-based characterization of prokaryotic community in a diversity of sample types

The paper compares 16S rRNA-based prokaryotic community characterization after direct DNA extraction versus metabolite extraction followed by DNA extraction across diverse samples, finding no impact on community composition.

Ingestion of Bacillus cereus spores dampens the immune response to favor bacterial persistence

This study shows that Bacillus cereus spores persist in the gut by evading immune responses and inducing amidases to dampen immunity, leading to bacterial growth and digestive symptoms.

Gut microbiota and holobiont metabolome composition of the Medaka fish (Oryzias latipes) are affected by a short exposure to the cyanobacterium Microcystis aeruginosa

This study shows that a 2-day exposure to Microcystis aeruginosa in medaka fish alters gut microbiota and metabolome composition, with microbiota changes occurring faster than metabolome changes.

Bacillus thuringiensis Cry1A toxins divert progenitor cell fate toward enteroendocrine lineage by diminishing cell adhesion with intestinal stem cells

This study shows Cry1A toxins from Btk disrupt cell adhesion in Drosophila, causing progenitor cells to differentiate into enteroendocrine cells instead of enterocytes.

Disruption of fish gut microbiota composition and holobiont metabolome by cyanobacterial blooms

This study shows that cyanobacterial blooms alter fish gut microbiota composition and holobiont metabolome, with potential ecological and aquaculture implications.

Fish metabolome from sub-urban lakes of the Paris area (France) and potential influence of noxious metabolites produced by cyanobacteria

The paper uses high-throughput metabolomics to analyze fish from urban lakes, showing that metabolome variations correlate with cyanobacterial noxious metabolites and environmental conditions.

Bacillus thuringiensis bioinsecticides induce developmental defects in non-target Drosophila melanogaster larvae

This study shows that Bt var. kurstaki bioinsecticides cause developmental defects in Drosophila melanogaster larvae by inducing apoptosis in enterocytes, which can be mitigated by dietary interventions.

Differential side-effects of Bacillus thuringiensis bioinsecticide on non-target Drosophila flies

This study examines the side-effects of Bt biopesticide on non-target Drosophila larvae, finding that high doses cause developmental delays and reduced emergence, while recommended doses have no effect.
