How to Kill a Parasite (podcast)

Every villain has his Achilles heel. And microscopic scoundrels are no exception. The challenge for those who wish to ward off microbial bad guys is to identify that weak spot. Now, scientists studying the toxoplasmosis parasite think they’ve done just that. They share the secret in the Proceedings of the National Academy of Sciences.

The toxo parasite is similar to the one that causes malaria. So finding a way to prevent these rogues from reproducing is high on researchers’ to-do lists. The bugs are tricky to take down, in part because they’re unpredictable in the way they multiply. Sometimes they get in and get busy making babies. Other times they copy their chromosomes but hold off parceling them out to their army of offspring until the time is right.
