Deciphering bacterial signalling

Bacterial communication is a potential strategy to control bacterial behaviours and thus, attenuate pathogen infectivity; however, identifying the signalling molecules that regulate communication pathways is challenging. Now, a robust strategy to rapidly identify previously unknown signalling peptides has been developed. This approach provides a means to map out and decipher bacterial signalling mechanisms.
