Scientists have long known that disease-causing parasites play host hopscotch to survive. Now, researchers at the University of California, Davis, and colleagues have mapped the game as it's played by Sarcocystis neurona , a pathogen that causes brain swelling in sea otters, which often kills them. Off the West Coast, it turns out the parasite slips from opossums to otters by way of clams—a complex transmission chain that's exacerbated by human activity, according to a paper published recently in Scientific Reports . The years-long study entailed capturing more than 700 sea o...
