Now that seemingly the flu outbreak storyline has been wrapped up on The Walking Dead (unsurprisingly, but disappointingly, with their ineffective treatments proving to be miracle cures), there’s still one more zombie microbiology topic I’d like to cover: what’s up with the bite, and is it the cause of death? I said previously: “We know the pathogen…

(As previously, spoilers abound) So on this week’s Walking Dead soap opera, we find that Daryl/Michonne’s group is still out and about searching for medical supplies. Back at the prison, the food situation is dire (apparently all the food stores were in the cell block where the infection broke out), so Rick and Carol head…

Warning: here be spoilers In many latter-day zombie movies, books, and TV shows, zombie-ism has a biological cause. In 28 Days Later, the infection is caused by the “Rage” virus, which escaped from a lab when animal rights activists break in and release a group of infected chimpanzees. Of course, one of the animals promptly…

Student guest post by Bradley Christensen No, this isn’t a clip from a science fiction movie.  Although dramatic, this does occur in the brains of some people and animals around on our home planet.  What is a prion you ask?  Prions are almost as mysterious to the scientists that research them as they are to…

Student guest post by Kyle Malter In many areas of the country there is a vile blood sucker that lurks in our forests, our parks and even our backyards.  What concerns us is not what this creature takes but rather what it leaves in our body after it bites us:  corkscrew shaped bacteria called spirochetes…

Student guest post by Julia Wiederholt I don’t think there is a single person that can claim to have never had the joyous experience (sarcasm intended) of suffering from the influenza.  We all recognize the common symptoms that accompany this infectious little virus taking up residence in our bodies: the chills accompanying a fever, the…
