Yersinia pestis

called the Septicemic plague which is when “Y. pestis bacteria spread through the bloodstream and cause a blood infection called septicemia” (Symptoms) The person infected would“develop severe bleeding problems, including sudden bleeding under the skin, scattered bruises, blood in the urine and abnormal bleeding from the mouth, nose and rectum.” The last type of the plague is called Pneumonic plague which is extremely rare. “It happens when Y. pestis bacteria infect the lungs and cause…

Y. pestis is a nonmotile, gram-negative, nonsporulating, rod-shaped coccobacillus and a facultative anaerobe. Infamous for being the causative agent in plague, has been implicated in at least three devastating pandemics in modern history. The second plague pandemic includes the Black Death epidemic which caused the deaths of a third of the estimated European population in the fourteenth century (Haensch et al, 2010). More than five hundred years after the Black Death, during the third plague…

human conflict, and abnormally warm and dry weather conditions can all cause increases in contemporary cases of plague (Oyston & Williamson, 2012). History of Emergence of Disease The plague is caused by the Yersinia pestis bacterium, which was identified in 1894 by Alexandre Yersin. Y. pestis is a Gram-negative bacillus that is found…

a killing spree unstoppable terrorizing the world. Voyagers who would trade fur were trading a death note too each other. Asia Minor to Mediterranean ports, this defied territorial right between living and death among every-one (Jueneman 11). Yersinia Pestis also known as “Black Death” in the Middle Ages the Black Death ruined and destroyed many lives. Although before the Black Plague the European popula-tion increased. Additional…

the next five years, the mysterious Black Death would kill more than 20 million people in Europe, almost one-third of the continent’s population. People who were perfectly healthy when they went to bed at night could be dead by the next morning. Y. pestis could be found almost everywhere in Medieval Europe, but it was particularly at home aboard ships of all kinds. By the end of 1348, the Black Death had struck Paris, Bordeaux, Lyon, and London. In the middle of the 14th century, there seemed to…

scarce. The outbreak cause much depression and killed mostly children then it did with adults based on their own immune system. Massive reduction in the number of food, people, and labor disappeared and was very hard to recover from it. Yersinia Pestis is the bacteria that entered its host’s…

researchers say that the disease is still in parts of the world. In Congo more than 10,000 people have gotten the disease throughout the last decade. Cases of the Bubonic Plague are slowly coming into the westward United States. The bacteria yersinia pestis started the Bubonic Plague and spread by fleas and rats. Overtime humans have developed better hygiene and more advanced medical studies the plague has reduced. The research has focused mainly on the countries in Africa that are mostly…

thought it was important to stay clean. With the badly kept condition of Europe, the Black Death spread quickly and easily. Fleas, that traveled through rats and other rodents on Asian ships, carried Yersinia pestis, a bacteria containing the bubonic plague. When a flea is infected with Yersinia pestis, they react with aggressive feeding behavior and tend to infect their host, the rats, with the bacteria. These rats, then carry the disease through the shabby country, infecting the people as…

choked with the stench of disease. The landscape, shriveled and fallow. A syrupy silence hangs over the land. It is 1348; the Black Death is here. Scampering up a mooring rope and into a trade vessel, a harbor rat carries a deadly passenger, the Yersinia pestis. And in October of 1347, the ship, docked in Messina, carries the Black Death into Europe (“Black Death”). Swollen lymph nodes, mottled black skin, and infection are merciless; victims eat lunch with their friends, and dinner with their…

This includes the cause of the disease and the effect that it had on the people after it was over. The Black Plague swept through the Western world from 1347-1351, coming in waves many more times after that. It was the result of the bacteria, Yersinia pestis, being introduced to the human body. This usually occurred when rats, carrying infected fleas, came into highly human populated areas, by land or by sea, and died. The fleas would then jump to a secondary host,…
