Effects of Microphallus papillorobustus (Platyhelminthes: Trematoda) on serotonergic immunoreactivity and neuronal architecture in the brain of Gammarus insensibilis (Crustacea: Amphipoda).
The larval flatworm Microphallus papillorobustus encysts in the protocerebrum of its intermediate host, Gammarus insensibilis, and changes the gammarid's responses to mechanical and photic stimuli. The resulting aberrant escape behaviour renders infected gammarids more susceptible to predation by birds, the definitive hosts of the parasite. We used immunocytochemical methods to explore the mech...
متن کاملDo distantly related parasites rely on the same proximate factors to alter the behaviour of their hosts?
Phylogenetically unrelated parasites often increase the chances of their transmission by inducing similar phenotypic changes in their hosts. However, it is not known whether these convergent strategies rely on the same biochemical precursors. In this paper, we explored such aspects by studying two gammarid species (Gammarus insensibilis and Gammarus pulex; Crustacea: Amphipoda: Gammaridae) serv...
متن کاملEcology of parasitically modified populations: a case study from a gammarid–trematode system
Examples of behavioural manipulation by parasites are numerous but the consequences of these phenomena on the ecology of host populations remains unclear. Through its effect on Gammarus insensibilis behaviour, the salt marsh trematode Microphallus papillorobustus splits its host population into 2 discrete subunits, one living at the surface (infected individuals) and the other living near the b...

Many parasites engaged in complex life cycles manipulate their hosts in a way that facilitates transmission between hosts. Recently, a new category of parasites (hitch-hikers) has been identified that seem to exploit the manipulating effort of other parasites with similar life cycle by preferentially infecting hosts already manipulated. Thomas et al. (Evolution 51 (1997) 1316) showed that the d...
متن کاملDifferential phenoloxidase activity between native and invasive gammarids infected by local acanthocephalans: differential immunosuppression?
Manipulative endoparasites can alter the behaviour and the physiology of their intermediate hosts in ways that increase the probability of successful transmission to the final host. This requires that the parasite is able to circumvent its host's immune defence. Successful immune evasion may depend on host-parasite coevolutionary history and the appearance of new hosts invading the local host p...
