Manipulative parasites in the world of veterinary science: Implications for epidemiology and pathology

One of the most complex and least understood transmission strategies displayed by pathogenic parasites is that of manipulation of host behaviour. A wide variety of parasites alter their host's behaviour, including species of medical and veterinary importance, such as Diplostomum spathaceum, Echinococcus spp. and Toxoplasma gondii. The manipulative ability of these parasites has implications for pathology and transmission dynamics. Domestic animals are hosts for manipulative pathogens, either by being the target host and acquiring the parasite as a result of vector-host manipulation, or by having their behaviour changed by manipulative parasites. This review uses several well-known pathogens to demonstrate how host manipulation by parasites is potentially important in epidemiology.
