[Abstract] The intestine is a central organ required for the digestion of food, the absorption of nutrients and for fighting against aggressors ingested along with the food. Impairment of gut physiology following mucosal damages impacts its digestive capacities that consequently will affect growth, wellbeing or even survival of the individual....

Biopesticides based on Bacillus thuringiensis kurstaki (Btk) and israelensis (Bti) spores and toxins are widely used to control insect pests, increasing environmental risks to non-target biodiversity. Here, we tested for potential effects of larval ingestion of Bt commercial formulations on Drosophila species. Doses equivalent to those...

Bioinsecticides based on Bacillus thuringiensis (Bt) spores and toxins are increasingly popular alternative solutions to control insect pests, with potential impact of their accumulation in the environment on non-target organisms. Here, we tested the effects of chronic exposure to commercial Bt formulations (Bt var. kurstaki and israelensis) on...

Bioinsecticides made from the bacterium Bacillus thuringiensis (Bt) are the bestselling bioinsecticide worldwide. Among Bt bioinsecticides, those based on the strain Bt subsp. kurstaki (Btk) are widely used in farming to specifically control pest lepidopteran larvae. Although there is much evidence of the lack of acute lethality of Btk products...

Bioinsecticides made of the bacterium Bacillus thuringiensis (Bt) are the bioinsecticide best sale worldwide. Due to the governmental policies and the public opinion, the use of such products has increased exponentially over the last decade. Among Bt bioinsecticides, those based on the strain Bt var. kurstaki (Btk) are widely used in farming to...

Using pathogens or high levels of opportunistic bacteria to damage the gut, studies in Drosophila have identified many signaling pathways involved in gut regeneration. Dying cells emit signaling molecules that accelerate intestinal stem cell proliferation and progenitor differentiation to replace the dying cells quickly. This process has been...

Members of the Bacillus cereus group are spore-forming bacteria commonly associated with foodborne outbreaks. The capacity of these bacteria to form highly resistant dormant entities, called spores, enables them to survive under extreme conditions. Bacillus thuringiensis (Bt) belongs to the group of B. cereus. Thanks to the toxins (named Cry)...

Bacillus thuringiensis subsp. kurstaki ( Btk ) is a strong pathogen toward lepidopteran larvae thanks to specific Cry toxins causing leaky gut phenotypes. Hence, Btk and its toxins are used worldwide as microbial insecticide and in genetically modified crops, respectively, to fight crop pests. However, Btk belongs to the B. cereus group, some...

SUMMARY Spores are considered as dormant entities highly resistant to extreme conditions. Among them, Bacillus cereus spores are commonly associated with foodborne outbreaks. Nevertheless, the pathological processes associated with spore ingestion and germination remain poorly understood. Here, we show that while ingestion of vegetative...
