Microsporidia are a large phylum of obligate intracellular parasites that infect an extremely
diverse range of animals and protists. In this chapter, we review what is currently known …

The role of natural selection in the evolution of trait complexity can be characterized by
testing hypothesized links between complex forms and their functions across species …

How a host fights infection depends on an ordered sequence of steps, beginning with
attempts to prevent a pathogen from establishing an infection, through to steps that mitigate …

Encountering suitable hosts is key for parasite success. A general assumption for disease
transmission is that the contact of a parasite with a potential host is driven by the density or …

To understand the mechanisms of antagonistic coevolution, it is crucial to identify the
genetics of parasite resistance. In the Daphnia magna–Pasteuria ramosa host–parasite …

Generalist hemiparasites may attach to many different host species and experience complex
parasite–host interactions. How these parasite–host interactions impact on the fitness of …

Host-parasite co-evolution is a process of reciprocal, adaptive genetic change. In natural
conditions, parasites can shift to other host species, given both host and parasite genotypes …

Polymorphidae is a monophyletic group of acanthocephalans distributed worldwide. Within
this family, Hexaglandula corynosoma is a specialist species that uses a single bird species …

The freshwater pearl mussel (Margaritifera margaritifera) is a highly host-specific parasite,
with an obligate parasitic stage on salmonid fish. Atlantic salmon (Salmo salar) and brown …

The genotype of Toxoplasma gondii (T. gondii) is expected to be disparate due to its
biological and epidemiological diversity; however, these disparities can only be found in …
