Pestis

It was named after Alexandre Yersin the man who found the disease Bacterium Yersinia Pestis. They wanted to find out the cause so that they knew if it happened again they could prevent it. Also they wanted to know for education and get more in detail with it. They found what they were looking for in the skeletons teeth. They looked in the

deaths (10). Plague has made such a great impact in history, that scholars even believe it was the cause of the collapse of the Roman Empire (2). Scientifically speaking the bacterium Yersinia pestis is what causes plague, and it’s not just a metaphor, but a disease that can be fatal (3). Yersinia Pestis, is a bacilli shaped capsular antigen and is able to show pigmentation on select culture media (9). It is from the

Bioterrorism and Plague Plague, also known as Yesirnia pestis, has wreaked havoc since the first documented outbreak in the 6th century, along with changing the course of history. Although bubonic plague is the most common form of plague, pneumonic plague is the more fatal form of the bacteria. It is the only form that has been successfully aerosolized by man and has the potential of taking down a mass of people in days. If used as a bioweapon, it would cause major damage.

Many people have a fear of rats, and that fear is completely justified since they were the source of a disease that killed about 200 million people worldwide, the Black Death. The Black Death or the plague is caused by a bacterial strain of Yersinia pestis. The disease is believed to have emerged in Central Asia around 1340. From Asia, the disease has managed to spread throughout the entire world. Even today, the disease still affects all parts of the world, including the United States. The disease

flea feeds off a rat, the Y.pestis grows in its gut. The bacteria soon blocks the valve that opens into the flea’s stomach and in an attempt to feed, they bite a host while also clearing out the bacterial obstruction. The flea regurgitates the Y. pestis onto the bites, therefore a flea could feed on as many rats as it can carry and once a flea comes in contact with a human and just as well bites them, the human is infected. Bubonic plague infects a humans immune system by causing inflammation. If

A nonmotile, gram-negative coccobacillus called Yersinia pestis spread by a vector called Xenopsylla cheopis also known as the Oriental rat flea and carried to humans by a host such as a rat. Furthermore, plague classified as a Category A Agents which is on the highest priority list (CDC. 2018). What are the

The Black Plague 25 million people died during the Black Plague, that’s about the same amount of people total in the U.S’s top ten most populous cities. The Black Plague affected a large portion of the population of the Eastern world during the Middle Ages. What was the Black Plague? How did the Black Plague affect Europe in the Middle Ages? Does the Black Plague still affect the world today? The disease killed approximately one-third of the entire population, and its source was largely a mystery

think about knowing that a mere flea can be the cause of the bubonic plagues epidemic. The more specific medical or scientific term for this disease is Yersinia Pestis. This was named after the doctor, Alexandre Yersin, who isolated the bacteria in 1894 during the pandemic that began in China in the 1860’s. The earliest traces of Y Pestis can be found all the way back to the Gobi Desert of Mongolia in the 1320’s. The cause of the sudden eruption is yet to be solved but the earliest major toll it has

Epidemiology Yersinia Pestis is found in many different countries. It usually effects people in the tropical, subtropical, and warmer temperate climates. This plague has effected countries in Africa, the former Soviet Union, the Americas, and Asia. Since the 1990’s most human cases have been seen in Africa (Plague). The three most common countries it effects are Madagascar, the Democratic Republic of Congo and Peru. The spreading of this disease goes with the delivery of rodents it infects, which

Plague erupted in 1320 in the Gobi Desert in central Asia. This plague was passed through rodents to other animals and then to humans through flea bites. This plague has three different names, The Bubonic Plague, The Black Death, and Yersinia pestis. Y. Pestis was named after one of its co-founders, Alexandre Yersin. It’s called the Black death because your blood dries underneath of the skin and turns it black, you can also get skin sores that turn black. This wasn’t the first time the Bubonic Plague
