Yersinia pestis

The Black Death, also known as the bubonic plague, caused by a bacteria called Yersinia Pestis, ravaged the population of Europe in the middle ages. “Localized epidemics of bubonic plague occurred with relative frequency, but only twice did the plague affect a wide enough swath of the population to be labeled a pandemic, or widespread epidemic” (The Black Death Arrives). When it did, over half the population of Europe died from exposure to the plague. Europe was densely populated and living…

Bubonic Plague in the Modern World Modern Countries Affected by the Plague In the world today, plague still exists, but it’s not as common as it was in the past. According to the World Health Organization,”In 2013, there were 783 cases reported worldwide, including 126 deaths.” Plague still occurs in parts of Asia, Africa, and the Americas. Most cases of the plague do occur in Africa, though. The countries where there are the most cases of plague are Peru, Madagascar, and the…

Bubonic plague is one of three types of bacterial infection caused by Yersinia pestis. Three to seven days after exposure to the bacteria flu like symptoms develop. This includes fever, headaches, and vomiting. Swollen and painful lymph nodes occur in the area closest to where the bacteria entered the skin. Occasionally the swollen…

The Black Death Did you know that the Black Death wiped out 30-60% of the European population? Some diseases can be almost power less but others are as mighty as an army and they can wipe out a large portion of the population. The Black Death, a bacteria, is deadly and wiped out about 75 million people, but it is less of a threat today. First, it is important to understand where the disease traveled to and some warning signs. To begin, the disease was passed on too many places, that was…

the Yersinia Pestis bacteria, symptoms like sneezing, coughing and having the chills would start. The Black Death consisted of three different types of plagues, bubonic, pneumonic and septicaemic. The symptoms would turn into either the bubonic, pneumonic or septicaemic plague. The bubonic plague was when the person started to form large lumps under the armpit, neck or groin called buboes. Buboes are lymph nodes which have become swollen to the size of an egg or apple, because of the Yersinia…

With an estimated thirty-eight million men, women, and children left dead, the Black Death that swept through Europe in the mid-fourteenth century is by and large the most devastating epidemic of medieval European history. Long thought to have been brought to the European continent by flea-carrying Asian traders, the plague left a crippling trail of death and destruction in its wake. Some scholars now challenge the source of the plague, saying it could not have come from fleas or rats but rather…

During the dark ages, the belief in witchcraft, commerce and the draconian response by the church to the threat of the Black Death, accelerated and in many ways helped spread the Bubonic Plague. Yersinia Pestis, often referred to as the Black Plague or the Black Death is a bacterial infection found mainly in rodents and their fleas, however, it was the rat fleas that spread the plague to humans, while the rats, simply carried the plague from region to region. Ole Benedictow (2005, para. 33)…

Gram positive: First, the bacteria sample is placed on a glass slide and heated only to the point of rendering it innocuous in terms of being infectious to the handler. Next, the bacteria sample is treated with a gentian violet-iodine solution for up to sixty seconds. The slide is then gently rinsed under clean water and the Gram solution is applied, which is a mixture of iodine and potassium iodide diluted in water. This step triggers a reaction to the gentian violet compound. Initially, the…

Black Death There were not enough living to bury the dead, and those rodents that were alive were the same who roamed the streets, carrying the fleas that had the disease. In Western Europe around 1339, Europe’s population had began to outgrow the food supply, and a major economic crisis had started to take place. It was very cold during the winter, and very dry during the summer, and due to the weather circumstances there was very low food supplies, lacking production of crops, and the crops…

There is a bacterium that is Yersinia pestis, which is usually found in animals, so after it would transfer into humans so yeah. So after a while those animals (usually mice and rats) would go into people’s home and then they would bite a person then another, then another and so on.so now…
