Description:
Identify the transmissible agent, presumably a ciliated protist, responsible for JOD in North Eastern United States. Establish the etiology and identity of the disease pathogen. Culture the transmissible agent, presumably a ciliated protist, in suitable media. Transmit the presumed pathogenic ciliate to cultured parasite free oysters and recover the parasite after the oysters have come down with the infection. Detection of the JOD organism in other species of cultured oysters and identify such a ciliate pathogen if one is found.

Nina Santos
Nina Santos is a Ph.D. student at the Chesapeake Biological Laboratory at the University of Maryland Center for Environmental Science. For her dissertation, she is focused on small shrimp-like crustaceans called mysids – an understudied yet important part of many estuarine and coastal food webs.

Developing a habitat model for mysids, an important link in Chesapeake Bay food webs
Mysids are important mesozooplankton prey for many species of fish in Chesapeake Bay and are an important link in transferring energy from lower to upper trophic levels. Mysids also serve as biological vectors for benthic-pelagic coupling due to their diel vertical migration and omnivorous prey-switching behavior, which makes mysids important regulators of food web architecture. Despite their central role in coastal food webs, surprisingly little is known about mysid ecology and dynamics in Chesapeake Bay.
