Explanation of the Bubonic Plague • The Bubonic Plague or “The Black Death” was a fatal disease spread by fleas, which lived on rats and humans at this time. • It was a pandemic. (Spread world wide) • It produces black blotches on the skin, hence the name “The Black Plague.’
Scientific and the common name of the Bubonic Plague • “Yersinia pestis” is the scientific name for the bubonic plague. • “The Black Plague” is the common name for this organism.
The Anatomy • Yersinia pestis, the deadly bacterium that causes bubonic plague, kills by cutting off a cell's ability to communicate with other immune cells needed to fight off the bacterial invasion. • YopJ, the protein Yersinia uses to block this signaling process, is one of six proteins injected by the bacteria into immune cells called macrophages.
The Arrival! • It arrived in October of 1347. • It started in Asia, then traveled to Europe, by rat infested Italian ships trading goods across the Mediterranean Sea.
