Come learn about the wide world of diverse animals that infest our planet. This is a Medical Entomology podcast so we will talk a lot about insects and arachnids that cause disease and also help us with our agriculture and food supply!
What do you give an injured lemon? LEMON-AID! Today’s podcast is all about saving the citrus, protecting the OJ, rescuing the grapefruits and pomelos: we are talking about citrus greening disease! Learn all about this insect vector sucking up tree phloem like a goshdarn juice box and how it spits out dangerous bacteria. Hear Lindsay discuss why we need citrus in our diet and why you’ve seen so many non-Navel orange fruits in your local supermarket. Get comfy. Pour a glass of orange juice or lemonade. This is Infested.

It’s the second episode of Infested! Let’s dive into an insect everyone loves to hate and a disease that will make your skin crawl. Yep, we are talking about pesky blackflies and the almost-eradicated disease they transmit: River blindness!

In this very first episode of Infested, we covered unique aspects of flea biology such as solenophagy, high strength legs and jumping capabilities through resilin protein, the benefits of having a laterally compressed body, as well as speciation through genal and pronotal combs. We covered the flea life cycle starting from the egg through to adult emergence including how pupae can survive dormant for years and will rapidly emerge with new host signs. One of the diseases that we discussed was plague, specifically Bubonic plague. Bubonic plague is caused by the transmission of Yersinia pestis bacteria into a vertebrate host through an infected flea bite. The bacteria are regurgitated into the host as the flea tries to take a blood meal while the bacteria forms a thick blockage in its upper digestive tract. We discussed some of the symptoms of plague as well as the historical implications of plague as it has consistently shaped history. Plague is still around today, including endemic levels in the Southwestern United States in enzootic cycles with small mammals like prairie dogs and squirrels. The second disease we dove into was murine typhus also known as flea-borne typhus. Murine typhus is caused by Rickettsia typhii and has many symptoms to other diseases which can make it easy to misdiagnose. We highlighted the current epidemic of murine typhus in California as well as how specific groups are targeted with blame for the epidemic. We talked about vector-borne disease can perpetuate inequality and societal discrimination: a theme that is central to this podcast! Below is our source material for further reading and exploration! We’ve broken it up into books, peer-reviewed journal articles, and media sources for easy searching. Thank you for listening! Want to stay in the loop with us on social media?
