Journal Article
Williams, P. (2025). Microbial Primer: Agr-mediated quorum sensing in Gram-positive pathogens. Microbiology, 171(7), Article 001590. https://doi.org/10.1099/mic.0.001590

Gram-positive bacteria commonly employ autoinducing peptide (AIP) signal molecules to co-ordinate gene expression at the population level. This primer provides a basic overview of agr-dependent quorum sensing systems and outlines how AIPs are produce...

Bio-instructive materials that intrinsically inhibit biofilm formation have significant anti-biofouling potential in industrial and healthcare settings. Since bacterial surface attachment is sensitive to surface topography, we experimentally surveyed...
