Abstract
Microorganisms employ sophisticated mechanisms for intercellular communication and environmental sensing, with quorum sensing serving as a fundamental regulatory process. Dysregulation of quorum sensing has been implicated in various diseases. While most theoretical studies focus on mathematical modeling of quorum sensing dynamics, the communication-theoretic aspects remain less explored. In this study, we investigate the information processing capabilities of quorum sensing systems using a stochastic differential equation framework that links intracellular gene regulation to extracellular autoinducer dynamics. We quantify mutual information as a measure of signaling efficiency and information fidelity in two major bacterial phyla of the gut microbiota: Firmicutes and Bacteroidetes.
