In animals and plants extracellular ATP (eATP) functions as signal and regulates the immune response. During inflammation intestinal bacteria are exposed to elevated eATP originating from the mucosa. However, whether bacteria respond to eATP is unclear. Here we show that non-pathogenic Escherichi...
Bacteria in the gut can modulate the availability and efficacy of therapeutic drugs. Interactions at this level have only recently started to being systematically mapped and the main underlying mechanism proposed is chemical transformation of drugs by microbes (biotransformation). Here, we invest...
Depletion of gut commensal bacteria significantly reduced nicotinic acid (NA) levels in the hemolymph and ovaries of Bactrocera dorsalis, leading to impaired ovarian development. This inhibition was reversed by exogenous NA supplementation. We identified Enterobacter hormaechei as a key NA-produc...

The gut microbiota is implicated in adverse effects associated with low-calorie sweeteners. Yet, the direct impact of sweeteners on gut bacteria has not been systematically assessed. Here we report interactions between 25 phylogenetically diverse gut bacterial strains and 39 commercially used swe...

Individuals vary widely in their drug responses, which can be dangerous and expensive due to treatment delays and adverse effects. Growing evidence implicates the gut microbiome in this variability, however the molecular mechanisms remain largely unknown. We measured the ability of 76 diverse hum...
The environmental contamination by manufactured chemicals has by some estimates exceeded the safe planetary boundary. Due to the widespread contamination of water and agricultural systems, a vast number of chemical pollutants make it into the food and hence into the human body. The gut microbiota...
