Abstract: Getting to know you Microbial persistence in hosts is usually not accidental, but reflects a shared merging of the biology of two or more disparate life-forms. Martin Blaser and Denise Kirschner advance the hypothesis that there has been selection for both microbes and hosts to maximize the fitness of both parties to a life involving parasitism or symbiosis, conforming to an evolutionarily stable strategy. They develop a model that can account for the persistence of three very different types of interaction between microbes in humans — involving Helicobacter pylori, Salmonella typhi and Mycobacterium tuberculosis.
