Abstract

Phages, the most abundant and diverse lifeforms on Earth, require strict parasitism for survival. During infection, temperate phages integrate both intracellular and extracellular host information to decide between lysis and lysogeny for replication. While various environmental and physiological factors influence the lysis–lysogeny decision, recent insights into phage–bacterium interactions reveal phages’ ability to communicate with and influence bacteria, leveraging the host’s quorum sensing system or small molecular signals. This article provides a succinct overview of current research advancements in this field, enhancing our understanding of phage–host dynamics and providing insights into bacteria’s multicellular behavior in antiviral defense.
Keywords: phage; bacterium; communication; quorum sensing phage; bacterium; communication; quorum sensing
