Influence of multiple infection and relatedness on virulence: disease dynamics in an experimental plant population and its castrating parasite.

Abstract excerpt

The level of parasite virulence, i.e., the decrease in host's fitness due to a pathogen, is expected to depend on several parameters, such as the type of the disease (e.g., castrating or host-killing) and the prevalence of multiple infections. Although these parameters have been extensively studied theoretically, few empirical data are available to validate theoretical predictions. Using the anther smut...
