Fight or learn to live with the consequences?

Abstract

Individuals can fight their infectious diseases by reducing the growth of a pathogen (resistance), but they can also ameliorate the disease it causes (tolerance). A recent paper shows that there is variation between mouse strains in tolerance to a rodent malaria and that this was negatively correlated with resistance. This is important, because tolerance has major implications for the epidemiology and coevolution of host-parasite interactions, but has been neglected in the animal literature.
