Understanding the complex interactions between filter-feeding species and zoonotic disease transmission in aquatic environments is crucial for accurately quantifying the ecosystem services provided by these organisms. This study explores for the first time the roles of freshwater bivalves in the transmission dynamics of emerging zoonotic nematodes using Angiostrongylus cantonensis, which has a complex life cycle (depending on invertebrate intermediate hosts). We used several European invasive and native molluscs and the Fatu-Hiva strain of A. cantonensis to address the situation during the spread of both the potential hosts and the parasite to Europe. Comparative analyses between four globally distributed freshwater bivalves (Corbicula fluminea, Sinanodonta woodiana, Dreissena polymorpha and Anodonta anatina) and two gastropod species (Biomphalaria glabrata and Planorbella duryi, known as common A. cantonensis hosts) were conducted to assess the elimination of two critical A. cantonensis developmental stages that may occur in aquatic environments. The clearance rates of early-stage (first-stage, known parasite of gastropods) and advanced-stage (third-stage, less host-specific) larvae from water and their potential developmental success within mollusc host tissues were evaluated. Unlike both gastropod species tested, the bivalves significantly depleted first-stage larvae from the water column, and the larvae did not develop to third-stage larvae in their tissues. However, only slight and statistically non-significant elimination from the water column by bivalves was observed in the case of third-stage larvae, even though some larvae still entered the bivalve body, and the third-stage larvae were found alive in the tissues of all studied mollusc species 16 days after infection. In particular, S. woodiana harboured a significantly higher abundance (mean of 2.48 larvae per gram of tissue) than the others. The results indicate that freshwater bivalves may play both a positive role in reducing A. cantonensis incidence and developmental success by eliminating first-stage larvae from aquatic environments, as well as a negative role, due to the susceptibility of all species (and S. woodiana in particular) to be infected by third-stage larvae, representing a newly described possible transmission pathway. Humans also consume this globally invasive bivalve in some regions where it coexists with A. cantonensis, presenting a potential health risk. This study underscores the stage specificity of the ecological functions of freshwater bivalves and the potential of using bivalves in disease control and prevention strategies, offering insights into ecosystem-based approaches to public health. These findings are particularly relevant for regions where freshwater bivalves are included in regulating ecosystem services and consumed, informing global strategies for waterborne disease management amidst ongoing species range shifts.
