bioluminescent bacteria spelling out words on plates
‘Painting’ with bioluminescent Vibrio harveyi, the model organism for quorum sensing studies in Vibrio species. Quorum sensing controls expression of the bioluminescence genes in V. harveyi, which enables the cells to ‘glow in the dark’ when grown at high densities. Photo by van Kessel Lab

Bacteria communicate using a cell-cell signaling system called quorum sensing that controls major processes in the cell, such as biofilms, motility, and secretion of virulence factors. The MIRA grant will fund studies in the van Kessel lab investigating the mechanisms of quorum sensing gene regulation in both Vibrio and Mycobacterium species and how this impacts bacteria in their environment.
