They appeared as small grayish spots and the presence of these bites always brought about the bubonic swelling in the affected region of the body. W.M.W. Haffkine created a vaccine made of killed broth cultures of the plague bacillus. What is in store for the future? Bubonic plague will continue to inflict humans for a long time to come because of plague¹s presence in so many burrowing rodents.
It originated from southern China and went along the Silk Road. It crossed through central Asia, India and also into the middle East (Stock Vol.4). Later on, scientists found out the cause of the Black Plague to start was ships and carriers, which had rats onboard that were infested by fleas. India was deeply affected by this, resulting in 13 million deaths (Wells 1097). The most common disease during the Black Plague was the bubonic plague.
The organs that are in the lymphatic system are the tonsils, adenoids, spleen and thymus. SYMPTOMS When a person contracts the bubonic plague infected patients develop a sudden onset of fever, headache, chills, weakness, and one or more swollen, tender and painful lymph nodes (called buboes). These symptoms usually result from the bite of an infected flea. Once it i... ... middle of paper ... ...teria. Six yops have been identified, however there are probably more.
The first to come into play were the seven rooms where the masked ball took place. These rooms were aligned from east to west, each one decorated with a different color, going from blue on the east end, to black on the west. These rooms symbolizing the stages of life starting from birth being the blue room and ranging all the way to death with the black room. The patrons of the ball seemed to enjoy each room but one, the black room, where "there were few of the company bold enough to set foot within its precincts at all” (Poe, 206). This is a symbol of not only how scary the room was, but also to not many being comfortable with the idea of death.
The rats and other various species of the rodent family would have caught the infection from fleas that carried the Y. pestis virus (Reedy, “The Bubonic Plague” 1). The rodents then carried these fleas and their virus across Europe where the fleas spread to human hosts. As the bacteria spread through the body, the recipient temperature would rise accompanied by a flood of other uncomfortable symptoms. In the most common form called Bubonic plague, the victim had “bubos or pus filled hard swellings” in the groin, neck, armpit, three of the places a persons lymph nodes are found. (Reedy, The Bubonic Plague” 1).
Its method of transmission was from ticks that bite infected rodents, and then transmitted to humans. As a result, the Plague has most famously been called "the Black Death" because it can cause skin sores that form black scabs. This research paper will discuss: the description, microbiological classification and identification, life cycle, diseases, diagnosis and treatments of Y. pestis. Throughout history, Y. pestis, the unknown causative agent of the plague, a disease that were first described in the Old Testament and have persisted into the modern era. Y. pestis has caused large-scale epidemics, resulting in many changes to the ... ... middle of paper ... ...e cycle is initiated again with another flea bite.
The Ships were forced to seek harbor elsewhere around the Mediterranean, which allowed the disease to spread very quickly (Truitt, 2001). This would be the beginning of a very traumatic event that would affect all aspects of European society. The Bubonic Plague generated from a bacterium called Yersina pestis, which is a one-celled organism that multiplies rapidly once inside its host and produces three types of symptoms, depending on how it is spread (Aberth, 2000). The bacterium that leads to the Bubonic Plague usually is found in the bloodstream of wild black rats. It is then posed to humans by fleas that feed on the blood of rats and then bite humans, in which the bacterium is passed into the human bloodstream (Aberth, 2000).
Popular belief states rats caused the Black Death. Because people can become sick with the bubonic plague from fleas that are carried by an infected rodent like a rat, it is common for individuals to also believe the Black Death was caused by a bubonic plague. The common belief blames the rats for the origination of the disease since it is believed by many that the Black Death was a bubonic plague. The theory involving the rats spreading the Black Death caused by the bubonic plague is invalid in that rats are also killed by the bubonic plague. If a rat were carrying the plague, they would die off faster than they could spread the disease onward.
Yersinia pestis – Gerneal Infection, Symptoms, Diagnosis, and Treatment Yersinia pestis, the culprit behind the infamous Black Death, spread by rat fleas, has cast a shadow over human civilization, taken the lives of countless peasants and nobles alike like a violent brute who murders invariably. There are three major forms of infection stages, the bubonic plague, the septicemic plague, and the pneumonic plague (primary and secondary), all are lethal if not treated with proper antibiotics. Due to similar symptoms, clinical diagnosis, the distinction between a common cold and a lethal infection is made difficult. However, though a potent murderer, Yersinia pestis can be easily eliminated by antibiotic treatment; survivors of the disease may be scarred. The plague has always been a shadow overcastting the dawn of mankind; it had hid in the darkness, where the rodents roam and the poor dwell; it had unleashed its terror upon, claiming the souls of nobles and peasants alike.
Epidemiology of the Black Death The plague bacillus affects wild rodents and their parasites, especially the black rat and its flea, Xenopsylla cheopis. A diseased rat, carrying the bacillae, may infect the flea which feeds on its blood, and in certain conditions the flea can carry the disease to human beings. It is thought by modern historians that this was the most common cause of the spread of the infection. There are two main forms of plague, of varying intensity. The more important is bubonic plague, which affects the lymph glands and leads to swellings (boils or "buboes") in the throat, underarm or, most commonly, in the groin.
