Vida social de las bacterias: aquí no hay quien viva
Abstract
For several decades the bacterial interactive relationship have been studied. Today incredible discoveries confirm the existence of information systems, as well as the establishment of altruism, cooperation, competition or even cannibalism levels. The researchers have settled down a resemblance between the behavior of the bacteria in a same ecosystem, with the behaviour of the animal communities and human beings. Thus, it is begun to speak of bacterial “sociomicrobiology”.In the present work two types of bacterian behaviour are detailed, the cannibalism and the formation of biofilms, Also are explained the mechanisms of communication cell-cell, the quorum sensing and the plásmidos ones, that allow the establishment of, more or less, a global behavior with a common operation.
