This project will develop a mechanistic understanding of marine transmission of the protozoal parasite Toxoplasma gondii. The team will investigate the role of marine aggregates in the transport of T. gondii and other zoonotic pathogens. An oceanography-based transport model will be coupled to epidemiological data to evaluate if T. gondii infection in sea otters can be predicted by the distribution of aggregate-associated and unattached T. gondii oocysts from terrestrial versus marine sources. The scientists will also investigate whether sea lions are definitive hosts capable of releasing infectious oocysts (current literature indicates that only felines can serve as definitive hosts).
