The effect of elevated mutation rates on the evolution of cooperation and virulence of Pseudomonas aeruginosa.

Abstract excerpt

Within-host competition between parasite genotypes can play an important role in the evolution of parasite virulence. For example, competition can increase virulence by imposing selection for parasites that replicate at a faster absolute rate within the host, but may also decrease virulence by selecting for faster relative growth rates through social exploitation of conspecifics. For many parasites, both outcomes...
