Yersinia

Kaleb Erhardt Allen World History 101 20 April 2015 Diseases have always been a threat to humans, all throughout history. One of the most destructive disease outbreaks in history was the plague outbreak which peaked in 1346 to 1353, in Europe, commonly known as the Black Death. This plague outbreak was extremely deadly and killed 30-60% of the European population at the time of the outbreak. The outbreak is commonly believed to have been caused by the bubonic plague, but modern evidence suggests

Catastrophic Killer In 1347, merchants arrived in Sicily from a trading trip in China. They carried Chinese goods on board with them, but they harbored an unknown killer, as well. Hiding on the rats living on board the cargo vessel was the bacteria Yersinia Pestis, or what would later become known as the Black Death.The Black Death was a disease that destroyed much of Europe’s population throughout the 14th century. This rodent-borne disease was a huge obstacle in human progress, as it killed millions

caused by the bacterium Yersinia pestis and carried by fleas. It was named the ‘Black Death’ as people who were infected had black welts and many died. Even if they were alive, they were gravely ill. It is devastating as the plagues spread rapidly to many parts of the world. Furthermore, it is highly contagious and thus easily spread from human to human. People who were infected had almost no chances of recovery or survival. The disease is caused by the bacterium Yersinia pestis. It is mainly found

were unknown until people started to notice problems that other people were having. The Black Death or “plague” that killed thousands in the fourteenth century may have evolved into a more modern version of itself. The “plague” is known as the “Yersinia pestis” bacteria, which is a rare zoonotic disease. These diseases are spread from animal to human (Newquist 239, Adamloakun M.D. 718). The bacterium lives in rodents such as rats and is carried by fleas (Newquist 238). When the fleas bite humans

Genetically Modified Products haven’t received a great reputation because many times they are perceived as chemical foods with a large amount of antibiotics and hormones. Although some of it is untrue, in certain populations including Europe, they are not seen as real food. The European culture prides themselves on fresh and natural ingredients used in their cooking. Many also feel that genetically modified foods are void of any nutritional value and are seen as a disregard for the human organism

And the nursery rhyme Ring-a-ring-a-Rosie derived from the Black Death as people used to carry sweet smelling flowers (e.g. Roses) to mask the ever present scent of death and decay. Although the Yersinia Pestis virus has not been fully eradicated (PubMed.com, 2004) modern medicine has managed to subdue most of the fatal ability of this bacteria. However, in contrast, Ming Dynasty China was relatively more sophisticated compared to Europe during

ships traveled to vast regions including China, India, Persia, Syria and Egypt. The plague is an illness cause by the bacteria strain Yersinia pestis. This particular bacteria strain is known to live within wild rodents especially rats. This disease was transmitted to humans when fleas began to feed upon the blood of infected rats. A toxin produced by Yersinia pestis left the fleas unable to digest the rat blood. This inability to digest the blood left the fleas to vomit infected rat blood into

The Black Death Nearly 650 years ago, in the beginning days of its time, Europe unfortunately was not the most thriving continent. Although it did have an abundance of food availability, this sent cities populations such as Florence, London, and Rome to grow by the dozens and brought much instability to food costs causing poverty and starvation to its inhabitants. Its level of agricultural production fluctuated while strain was put on the rest of the economy. Such calamity was still not the highest

The Plague The black rat originated in Asia in the Mongolian Empire. They were wild borrowing animals who hosted the microorganism Yersinia pestis, which was natural disease in the wild borrowing animal’s population. Humans and these animals did not cross paths until the development of roads crossing through the domain of the rats. Following the onset of the leprosy scare throughout Europe, another deadlier infection was about to change their perspective on life and the world. The Church held the

the fleas it carried did (Dobson). The plague is caused by a bacterium called Yersinia Pestis. It is spread by the bites of the fleas (“The Black Death”). Most of the time the plague stayed within the rat population, but when large numbers of rats were affected and die off, the fleas
