Dynamics of parasite communities and interactions between wild and domestic ruminants

Dynamics of parasite communities and host-parasite-environment interactions can be influenced by different factors. The present note, by discussing some field experiences in wild and domestic ruminant populations, approaches eco-epidemiology of abomasal nematodes in relation with host health and dynamics. Factors possibly playing a role in the host-parasite relationship are discussed, as well as possible use of macroparasites as ecological and sanitary indicators. The above topics are approached in a management perspective, in particular regarding interactions between domestic and wild ruminant populations.
