Parasite Transmission in Social Interacting Hosts: Monogenean Epidemics in Guppies
BACKGROUND Infection incidence increases with the average number of contacts between susceptible and infected individuals. Contact rates are normally assumed to increase linearly with host density. However, social species seek out each other at low density and saturate their contact rates at high densities. Although predicting epidemic behaviour requires knowing how contact rates scale with hos...
متن کاملSex-Specific Differences in Shoaling Affect Parasite Transmission in Guppies
BACKGROUND Individuals have to trade-off the costs and benefits of group membership during shoaling behaviour. Shoaling can increase the risk of parasite transmission, but this cost has rarely been quantified experimentally. Guppies (Poecilia reticulata) are a model system for behavioural studies, and they are commonly infected by gyrodactylid parasites, notorious fish pathogens that are direct...
متن کاملInteractions between males guppies facilitates the transmission of the monogenean ectoparasite Gyrodactylus turnbulli.
In a previous study we found that female guppies shoaled more than males and that there was greater transmission of the ectoparasite Gyrodactylus turnbulli between females. Here, to test for a possible sex bias in parasite transmission, we conducted a similar experiment on single sex shoals of male and female guppies, observing host behaviour before and after the introduction of an infected sho...
متن کاملParasite predators exhibit a rapid numerical response to increased parasite abundance and reduce transmission to hosts
Predators of parasites have recently gained attention as important parts of food webs and ecosystems. In aquatic systems, many taxa consume free-living stages of parasites, and can thus reduce parasite transmission to hosts. However, the importance of the functional and numerical responses of parasite predators to disease dynamics is not well understood. We collected host-parasite-predator cooc...
متن کاملModelling Interacting Epidemics in Overlapping Populations
Epidemic modelling is fundamental to our understanding of biological, social and technological spreading phenomena. As conceptual frameworks for epidemiology advance, it is important they are able to elucidate empirically-observed dynamic feedback phenomena involving interactions amongst pathogenic agents in the form of syndemic and counter-syndemic effects. In this paper we model the dynamics ...
