The model is based on T. gondii transmission, and represents the complex life cycle with trophic transmission and vertical transmission in IHs: felids (DHs) excrete oocysts in the environment through their faeces; rodents (IHs) are contaminated by sporulated oocysts or vertical transmission; DHs get infected by preying … WebParasite Ecology Group

Modification of hosts

WebBecause transmission between host species often depends on predation (i.e., trophic transmission), parasite-induced alterations in host behavior or appearance that increase predation risk may be selec- tively favored (Lafferty 2013; Poulin and Maure 2015; Bernal et al. 2016; Hafer and Milinski 2016; Poulin 2024; Herbison et al. 2024). WebIn the laboratory, we found that boldness in an open field test was positively correlated with parasite intensity. These parasite-induced behavioral changes may render infected minnows more susceptible to predators, which would serve to facilitate trophic transmission of parasites to the bird host.

"WebBehavioural manipulation often manifests as parasite induced tropic transmission (PITT), in which parasites with multiple host life cycles change the behaviour of one host in such a way as to enhance the likelihood of the host being eaten by a predatory species that is the next host in the parasite’s life cycle ( Moore, 2002; Lafferty & Shaw, … " - Parasite induced trophic transmission
