The only alphabet guaranteed to make you want to wash your hands. Made by one, Jennifer Gardy.
In related news, this video taught me that the parasite giardia is sometimes called "beaver fever". Why? Because one of its major reservoirs — species that can comfortably host a parasite and pass it on to others — is, yes, the beaver.
Now here's the part you probably don't want to hear. Giardia is transmitted via what's known as the "fecal-oral route".
Now, nobody intentionally goes out and eats beaver shit. (One hopes. But this is the internet.) But beavers do shit in the woods. Near woodland streams. Which means that unwary hikers and backpackers can end up ingesting giardia when they drink from what appears to be crystal-clear waters.
