"Exploring the latest in the green and the unseen!"

In this episode, DJ Slide presents a UC Davis led investigation into the deaths of four southern sea otters off the California coast. The discovery that these otters died of Toxoplasmosis raises questions about how T. gondii causes disease and how these otters acquired a traditionally terrestrial pathogen.
