Eastern oyster, Crassostrea virginica, are a keystone species and a focal aquaculture species. These bivalves consume large amounts of microplastics (MP’s) as they filter surrounding waters for food. Microbes can colonize the surface of MP’s, including human pathogens of the genus Vibrio, which can then be transmitted to humans when oyster are consumed raw. This project aims to explore MP’s as a vector for human pathogens under projected climate change scenarios.
