Research Paper on Yersinia Pestis
Yersinia Pestis is a bacteria (Palmer). And the common name for Yersinia Pestis is Y. pestis and its scientific name is as stated before Yersinia Pestis (Brubaker). And while there are nineteen species of Yersinia, only three of those species “are etiological agents in humans”(Brubaker), and Yersinia Pestis is actually one of them. The other two species are “Y. enterocolitica, and Y. pseudotuberculosis” (Brubaker).
The organism, Yersinia Pestis maintains its “ existence in a cycle” (“Plague Ecology and Transmission” ) that involves rodents and fleas that attach themselves on the already infected rodents(“Plague Ecology and Transmission”). And due to the mild death rate of certain rodents, Scientist actually believe that Yersinia Pestis circulate at low rates within populations. And that the rodents that didn't die actually become “ long- term” carriers (“Plague Ecology and Transmission”). This cycle is called “the enzootic cycle” (“Plague Ecology and Transmission”).“Occasionally, other species become infected, causing an outbreak …show more content…
Bacteria can then spread to other organ systems, especially the lungs; fever, chills, prostration, and death may occur” (Palmer). There is also a ten to twenty percent chance that you can get plague pneumonia if you are bitten by a flea that is a plague vector (Palmer). “ Pneumonia starts as a secondary lung infection during bubonic/solpticemic disease; it may then be transmitted from human to human by bacterial aerosols that are spread by coughing. It has a rapid course in close quarters and is almost universally fatal if untreated. In some individuals, the skin

    Summary Of The Black Death Ziegler

    At the time, this seemed to be the most logical and valid theory for many people but that was due to the lack of scientific and medical knowledge that the people had during the fourteenth century. We now know that the Black Death was caused by rats that were carrying the Yersinia pestis bacterium and that oriental rat fleas would bite the resistant carrier rats and become infected with Yersinia pestis. After a few days the Yersinia pestis would multiply creating blockage in the flea’s midguts starving the fleas. The fleas would then begin to feed aggressively and would continuously try to rid of the blockage by regurgitating, causing hundreds of bacterium to enter the wound. This would infect the host, and as the population of non-resistant rats died out, the fleas would then move on to different hosts such as humans, causing a human pandemic.…

    How Did The Bubonic Plague Affect Europe

    It was caused by the fleas that lived on rats. The fleas have a bad bacteria in their stomach, but the bateria can make it to a point in which the flea gets sick and bites a rat; the bad bacteria is then passed onto the rat and gets into the bloodstream. All of the fleas who bite the infected rat will then absorb the plague and pass it on to other rats or humans. "The other thing that made the pneumonic form of the…

    The Black Death: The Bubonic Plague

    Also it could be contracted from breathing in airborne droplets from people who already had the infection in their lungs. The first symptoms of the bubonic plague often appear within several days: headache and a general feeling of weakness, followed by aches and chills in the upper leg and groin, a white coating on the tongue, rapid pulse, slurred speech, confusion, fatigue, apathy and staggering gait. A blackish pustule usually would form at the point of the fleabite. By the third day, the lymph node begins to swell. Because the bite is commonly in the leg, the lymph nodes in the leg swell, which is how the disease got its name. The swelling then becomes tender, and perhaps as large as an egg. The heart begins to flutter rapidly as it tries to pump blood through swollen, suffocating tissues. Subcutaneous hemorrhaging occurs, causing purplish blotches on the skin. The victim's nervous system began to collapse, causing dreadful pain and bizarre neurological disorders. By the fourth day, wild anxiety and terror overtake the sufferer and then the sense of resignation, as the skin blackens and the rictus of death settles on the body.…

    Yersinia Plague: The Protagious Outbreak Of The Black Death

    Plague is a disease that is caused by a bacterium called Yersinia Pestis (“Plague: Ecology and Transmission”) Yersinia Pestis is a bacterium that is most commonly found in rodents and other small mammals. When transmitted to humans, the subsequent disease, plague, takes hold (“Plague: Ecology and Transmission”). The disease has three forms, all of which are deadly in their own right and were a part of the Black Death outbreak. The first and most common form is the bubonic plague. The bubonic plague is usually spread by infected fleas that bite humans. The symptom that gave this form of the disease its name is the occurrence of one or more swollen lymph nodes that are called “Buboes.” ("Plague: Symptoms") The septicemic plague is the second form and it is transmitted…

    The Black Death During The Elizabethan Era

    Because many families allowed their own pigs to roam and graze outside the city walls and the city streets, the disease thrived in the filthy conditions of Medieval Europe. While studying the contagions of the disease, modern scientists have discovered that the disease was spread by a bacterium called Yersina pestis. They have also found that the bacteria is transmitted through the air, as well as from fleas and rats. The disease was especially prevalent because these vermin could be located practically everywhere in medieval Europe. They were most notably found aboard ships, which was how they spread to so many European port cities so quickly.…

    The Black Death: The Bubonic Plague

    It all started as a mere headache, then grew into something greater rapidly. The plague came in three different forms. The first form was the bubonic variant, which was the most common, caused swelling lumps called buboes. They were also called tumors. Buboes could range in size from an egg to an apple. They appeared on the victim’s neck, armpit or groin area. People say that a gush of blood from the victim’s nose was often the sign of inevitable death. Soon after this the symptoms started to change, black and purple spots started showing up all over the body such as the arms or thighs. Sometimes they were very large, but they were usually small. These spots were often a sign of death and from this point on, there’s nothing to do to stop it. The second form is the pneumonic plague. It attacked the respiratory system and was spread by breathing the exhaled air of the victims. The third form is the septicemic version, which attacked the blood…

    According to the history learning site, “evidence produced by forensic scientists and archaeologists in 2014 from human remains in the north of the City of London suggests that fleas could not actually have been responsible for an infection that spread so fast it had to be airborne. Once the disease reached the lungs of the malnourished, it was then spread to the wider population through sneezes and coughs.” (Trueman, 2015).…
