Permitted reuse is defined by your choice of one of the following user licenses:. A particular parasite may occupy a specific site and utilize certain host resources and this defines its niche. A parasitic relationship is the opposite of a mutualistic relationship. This strategy is usually costly to the host, and has led to the evolution of a suite of adaptations in hosts, in order to defend themselves against parasitism, and in parasites, in order to effectively parasitize their hosts.

Highly virulent parasites showed adaptation to local hosts for migration rates of up to 10% of the population per generation. Parasitic infections are common in rural or emerging areas of Africa, Asia, and Central and South America and are less common in industrialized areas. So a niche is a description of the parasites requirements, not of host attributes. providing the parasites with a strong potential for phenotypic diversification and rapid adaptation for instance through anti-genic variation or expression of alternative invasion ligands or nutrient transporters (Rovira-Graells et al.
