    00:01 Yersinia, a bacteria.

    00:03 The Yersinia are gram negative rods such as you see in the image on the slide.

    00:09 They’re facultatively intracellular and are quite mobile when evaluated under a microscope.

    00:15 They are oxidase negative and lactose negative.

    00:19 And they’re commonly known pathogens at least in the gut sense.

    00:25 Yersinia enterocolitica, the second bullet point is the most common.

    00:30 Yersinia pestis, unfortunately, is our huge foe because it has been associated in the past with the Plague, the Black Death.

    00:39 It is quite nasty and at the 1300s in the form of the Black Death, it eradicated over a third of Europe’s population.

    00:48 Because it is so nasty, let’s talk about it first.
