As the average water temperature of Narragansett Bay and other coastal ponds in Rhode Island continue to increase due to climate change it is probable that the abundance of Vibrio parahaemolyticus (Vp) and Vibrio vulnificus (Vv) will increase as well. Vibrio are gram‐negative bacteria that can accumulate in tissues of the eastern oyster ( Crasssostrea virginica). While vibrio is not pathogenic to the oyster it can cause gastroenteritis in humans that consume the raw oysters. Eastern oysters are commonly infected with three diseases: Perkinsus marinus (Dermo), Haplosporidium nelson (MSX) and Haplosporidium costale (SSO). These parasites can cause severe morbidity and mortality in cultured and wild oysters. Animals that are affected by any disease have a decreased immune functionality and it is probable that these diseased oysters are more likely to accumulate higher levels of Vp and Vv. To test this theory, oysters were collected from Roger Williams University during the summers of 2016 and 2017. Composites of 10 oysters were tested using multiplex qPCRs for Vp and Vv in conjunction with a second multiplex qPCR to determine the abundance of those three disease. Individuals were also tested in order to increase accuracy of the association because composites which produce averages may mask important relationships only identified in individual animals.
