Density-Dependent Prophylaxis in Freshwater Snails Driven by Oxylipin Chemical Cues

Abstract: While animal aggregations can benefit the fitness of group members, the behaviour may also lead to higher risks of parasite infection as group density increases. Some animals are known to moderate their investment in immunity relative to the risk of infection. These animals exhibit density-dependent prophylaxis (DDP) by increasing their immune investment as group density increases. Despite being documented in many taxa, the mechanisms of DDP remain largely unexplored. Snails are known to aggregate and experien… Show more

“…Parasite prevalence is assayed through examination of the host and its tissues, so parasite encounters that do not develop into an infection may easily be missed. However, empirical evidence indicates that parasite presence leads to an increase in physiological defence mechanisms in hosts, particularly when parasite encounters are increased by increasing number of conspecifics, which leads to higher positive density‐dependent transmission rates (Cotter et al, 2004; Friesen et al, 2022; Silva et al, 2016). Similarly, our data indicate that the presence of parasites may have profound effects on behavioural outputs even in resistant study populations and should be considered in studies on how interactions between parasites and hosts influence ecological landscapes.…”
