Appraisal of Microbial Evolution to Commensalism and Pathogenicity in Humans

Show other versions (1)

The human body is host to a number of microbes occurring in various forms of host-microbe associations, such as commensals, mutualists, pathogens and opportunistic symbionts. While this association with microbes in certain cases is beneficial to the host, in many other cases it seems to offer no evi...
