In a stunning twist, intestine pathogens like Salmonella aren’t repelled by way of fecal indole; as an alternative, they exploit it to find nutrient-rich environments, turning a microbial protection right into a colonization merit.

In spite of being a identified bacterial repellent, indole in faeces does no longer save you intestine infections. A up to date eLife find out about investigated how enteric micro organism navigate the conflicting chemotactic indicators within the intestine and the way those interactions facilitate colonization.
Intestine bacterial colonization
Motile intestine micro organism colonize the gastrointestinal tracts of people and different animals by the use of chemotaxis. They resolve chemical effectors within the lumen and navigate the inner setting to proliferate. This navigating procedure is regulated by way of chemoreceptor proteins, which determine chemical effectors and switch indicators via a phosphorylation cascade. The chemical signalling successfully controls bacterial flagellar rotation and…
