Insight into the dynamics of parasite–host relationships of higher vertebrates requires an
understanding of two important features: the nature of transmission and the development of
acquired immunity in the host. A dominant hypothesis proposes that acquired immunity
develops with the cumulative exposure to infection, and consequently predicts a negative
relationship between peak intensity of infection and host age at this peak. Although previous
studies have found evidence to support this hypothesis through between-population …
