From the interplay between different organisms emerged the concept of “identity”, i.e. the need to distinguish “self” from “non-self”. Multicellular organisms have developed immune systems responsible for the detection of “non-self” organisms that lead to the activation of appropriate responses to maintain the organism in a state of homeostasis. In opposition, bacteria have developed mechanisms (virulence factors) to avoid their identification as harmful, in order to assure their survival within the host. (...)"
