This episode we explore the delightful diversity of Escherichia coli , the ubiquitous bacterium that predates humans and can range in virulence anywhere from “you won’t even know I’m there” to “this is really, really, really gonna hurt”. Today we cover the good, the bad, and the ugly: you’ll hear about the innumerable contributions of E. coli to the fields of genetics, evolution, and microbiology, a detailed account of how pathogenic strains ...

And we are honored to be joined by Jay Gironimi, author of “Can’t Ea...
Aug 20, 2019•2 hr 38 min•Transcript available on Metacast Walking through a forest at dusk, you’ve likely heard the croaks and groans of frogs and toads forming a chorus in the damp undergrowth. But what if the forest were suddenly, inexplicably, silent? In the 1980s scientists started noticing the forests becoming quieter as amphibian populations around the globe began to decline -- rapidly. Today we are joined by Dr. Taegan McMahon from the University of Tampa to discuss our first ever wildlife disease: chytridiomycosis. Chytrid fungus, or Bd for sho...

Jul 23, 2019•2 hr 51 min•Transcript available on Metacast Giardia may be the most common intestinal parasite in the US and one of the most common worldwide, but did you know it was only in the last 40 years that it was officially recognized as a human pathogen?! In today’s episode, we’ll travel back to a time before humans knew microbes even existed to discover alongside Leeuwenhoek a whole new world of animalcules like giardia. We’ll find out how seeing these critters for the first time changed everything, and how long it has taken to recognize their ...
Jul 09, 2019•1 hr 15 min•Transcript available on Metacast Imagine this: a sickness where millions fell into a deep slumber from which they never woke. Of those that did, many remained trapped in a cage of their own bodies, unable to move or speak but fully aware of the world around them. Imagine that this sickness appeared suddenly, without warning, and spread across the globe, affecting millions in just a few decades. Then, just as quickly as it emerged it disappeared. Survivors were left to suffer, eventually forgotten, while hundreds of questions re...
Jun 25, 2019•1 hr 28 min•Transcript available on Metacast On this very special crossover episode with our friend Matt Candeias from In Defense of Plants, we’re switching things up from poison to remedy, focusing on the plant-derived wonder drug, aspirin! We cover the ancient use of salicylic acid-containing willow bark to relieve pain and fevers and then reveal how such a harsh compound was transformed into a useable pharmaceutical. We also delve into what happens in your body when you pop an aspirin and discuss why on earth so many plants make this in...
Jun 11, 2019•1 hr 19 min•Transcript available on Metacast This week's episode comes with a warning: don't attempt this at home. While self-experimentation has led to many a scientific breakthrough, we're definitely not advocating it. But it happened to work out for the best for Barry Marshall and Robin Warren, even earning them a Nobel prize. That’s right folks, today we’re talking about none other than Helicobacter pylori , the curvy little bacterium identified only a few decades ago to be a causative agent of peptic ulcer disease, a major risk factor...

From the first discovery of the virus in a Ugandan jungle, to the heartbreaking effects only recently discovered, to the future of Zika research and vaccine development, we'll fill you in on everything yo...
Apr 16, 2019•1 hr 5 min•Transcript available on Metacast Today we’re taking a bite out of hookworm, our first macroparasite. We start, as all hookworm journeys must, from the dewy grass, where larvae burrow into your exposed flesh and make their long and winding way to your guts, where the eggs of a fortunate few will be immortalized in fossilized poop. It’s a tale of human migration, of failed eradication, and of overburdened populations. So pull up a chair, take off your shoes, and rest your feet in the cool dew-soaked grass. But watch out for the g...

And not just any protein, a protein you already have in your body . Are you sweating yet? Good.

Pour yourself a quarantini and cozy up with us as we tell you a story of a bacterium that slowly strangles children to death, a scientific quest that helped shape the understanding of infectious diseases, and a great dog sled race across wild and frozen lands to stop death in its tracks. The main character of this story is, you guessed it, Diphtheria. This dreaded disease still lingers, infecting children throughout the world to...
Dec 24, 2018•58 min•Transcript available on Metacast We've gotten pretty graphic on this podcast before, but this episode takes it to a whole new level. The omnipresent Staphylococcus aureus is a bacterium that wears many faces. Often that face is harmless, but Staph has the power to invade and infect nearly every organ of the body, leaving destruction (and a lot of pus) in its wake. While Staphylococcus aureus has been wreaking havoc on humans since well before the discovery of antibiotics, Methicillin-resistant Staph aureus (MRSA) has risen to t...
