Summary The opportunistic pathogen Pseudomonas aeruginosa controls the production of virulence factors by quorum sensing (QS). Besides cell density, QS in P. aeruginosa is co-regulated by metabolic influences, especially nutrient limitation. Previously, a co-culture model system was established consisting of P. aeruginosa and the chitinolytic bacterium Aeromonas hydrophila, in which parasitic...

We searched for a source of reactive oxygen species (ROS) in the cytoplasm of the human pathogen Vibrio cholerae and addressed the mechanism of ROS formation using the dye 2’, 7’ -dichlorofluoresceine diacetate (DCFH-DA) in respiring cells. By comparing V. cholerae strains with or without active Na+ -translocating NADH:quinone oxidoreductase (Na+ -NQR), this respiratory sodium ion...

Abstract Gut microbiota is important to human health. Specific dietary glycans promote favorable microbiota growth and inhibit pathobionts. Dietary glycans most relevant to adults and weaned infants are derived from plants or lactose; human milk oligosaccharides (HMOS) are most relevant to breastfed infants. Their efficacy in supporting bacterial growth is compared to determine...
