Heritable variation in host tolerance and resistance inferred from a wild host–parasite system

Abstract: Hosts have evolved two distinct defence strategies against parasites: resistance (which prevents infection or limit parasite growth) and tolerance (which alleviates the fitness consequences of infection). However, heritable variation in resistance and tolerance and the genetic correlation between these two traits have rarely been characterized in wild host populations. Here, we estimate these parameters for both traits in Leuciscus burdigalensis, a freshwater fish parasitized by Tracheliastes polycolpus. We us… Show more

“…The causes of variation in tolerance are less well known. A few recent studies have demonstrated genetic variation for tolerance [6][7][8]. Environmental effects on tolerance have been demonstrated in a few invertebrate host-parasite systems [9], but there are, as far as we are aware, no explicit analyses of the effect of nutritional status or other environmental factors on tolerance to parasites in vertebrates.…”
