Preface

Bacteria are microorganisms, which communicate with each other using three different mechanisms. Historically, the chemical signalling mechanism was first discovered and extensively discussed by scientists. Chemical molecules have been identified for this mechanism and they are technically known as autoinducers. Communication through sound is discussed by the end of last century but not so well mentioned in the literature. The most recent mechanism was discovered a couple of years before by the researchers from the USA and the European Union known as communication through electrical signalling. These three types of communication are used by the bacteria to make their own survival master plan in a complex environmental condition. The chemical signalling mediated communication process depends on the number density of the bacterial cell. This dependence of number density is commonly known as a quorum sensing mechanism. The study of the mechanisms for communication among the bacteria needs
