We can probably all agree that the thought of a tapeworm hiding out in your gut is not a pleasant one. Nor is the image of tapeworm larvae forming cysts in your muscles, organs, and even your brain. So listening to an entire episode on these parasitic worms? We understand why that may seem like a bit much. But trust us, the world of these worms is too fascinating and important to be missed. In this episode, we break down the biology of the tapeworm species that commonly infect humans and discuss the role of these parasites as a leading infectious cause of epilepsy around the world. Then we venture into the ancient and not-so-ancient history of these tapeworms, starting at “who was infected first – the human or the pig?” and ending with “what was the tapeworm diet all about anyway?” Finally, we wrap up the episode with a look at tapeworm by the numbers today. Tune in wherever you get your podcasts!
