According to the cell density bacteria can regulate their gene expression. Gene regulation is initiated by the release of signaling molecules into the environment which are called autoinducers. When the population density increases, these autoinducers accumulate extracellularly and these can be detected by the bacteria through quorum sensing.
We found that E. coli make use of indole quorum-sensing signals to prevent it from infection by T4 phage. This has been acknowledged for the first time that E. coli utilizes antiphage defense mechanism regulated by quorum sensing. We proposed that through quorum sensing E. coli is protected in conditions where there is increased risk of infection as for example during growth in high cellular density in which there is mixed species environments. In microbial communities, quorum-sensing is a general phenomenon which controls E. coli susceptibility to phage.

Abstract
According to the cell density bacteria can regulate their gene expression. Gene regulation is initiated by the release of signaling molecules into the environment which are called autoinducers. When the population density increases, these autoinducers accumulate extracellularly and these can be detected by the bacteria through quorum sensing.
We found that E. coli make use of indole quorum-sensing signals to prevent it from infection by T4 phage. This has been acknowledged for the first time that E. coli utilizes antiphage defense mechanism regulated by quorum sensing. We proposed that through quorum sensing E. coli is protected in conditions where there is increased risk of infection as for example during growth in high cellular density in which there is mixed species environments. In microbial communities, quorum-sensing is a general phenomenon which controls E. coli susceptibility to phage.
