Parasitology An Integrated Approach
by Alan Gunn
Edition: 1st., 2012
Protozoan and helminth parasites are fascinating organisms and examples of their parasitism are found in a broad range of hosts, including plants, invertebrates and vertebrates. The interaction between a parasite and its host is complex and dynamic. Therefore we think that studying parasitology is a useful tool for appreciating a range of concepts in biological sciences including growth and reproduction, biochemistry, immunology and pathology.
Parasites do not live within their hosts in isolation. We feel that it is instructive to recognise how an individual organism might interact with other members of the same species, other species of protozoa and helminths and other classes of microorganism within a particular host. The effects on the host of harbouring a particular species of parasite are influenced by a range of host factors, including genetic constitution, immune status, and behaviour. Also, for parasites of humans in particular, consideration of social, religious, and cultural factors is often necessary. We have therefore called this book Parasitology: An Integrated Approach to emphasise how parasites influence, and are influenced by, a complex web of interacting factors.
