ABSTRACT
Parasites can be reliable tool in assessing the effects of ecosystem disturbances. However, they can respond in different ways and any changes in assemblages are not easily predictable. Descriptive modelling could be a first step since providing information on the relative importance of a pollutant on parasite occurrence. We chose the zebra mussel, as test organism and twelve sites in France and the United States. Contaminants had not the same impact on microparasite occurrence. Metals enhanced the infection, except zinc associated only with higher prevalence of the commensal ciliate Conchophthirus acuminatus. We should note that Rickettsiales-like organism infection is higher at higher Ni and Cr concentrations. Models indicated also that the most polluted sites were also those with higher rates of co-infections. Therefore, the continuous contamination of freshwater ecosystems implies a significant risk promoting the development of parasites that may affect bivalve populations and other species belonging to their life-cycle.
