Owing to its compositional and chemical complexity, much of the gut microbiota metabolome remains poorly characterized. Aromatic amino acids (AAAs) have a history of being privileged substrates for the biosynthesis of diverse bioactive metabolites and thus represent a potentially rich source of b...

The pregnancy vaginal microbiome contributes to risk of preterm birth, the primary cause of death in children under 5 years of age. Here we describe direct on-swab metabolic profiling by Desorption Electrospray Ionization Mass Spectrometry (DESI-MS) for sample preparation-free characterisation of...

Contamination of fresh produce with human pathogens remains a serious public health and economic concerns due to the absence of effective kill steps in the farm-to-fork chain. In particular, the pathogenic Escherichia coli O157:H7 has been implicated in multiple illness outbreaks linked to lettuc...
