How many victims does yersinia pestis affects?
654646516516515
Most common victim yersinia pestis preys upon?
a short-lived inflammation of the intestine known as enterocolitis. Most often the very end of the small intestine is involved, an area known as the terminal ileum. The result is gastroenteritis,
What does yersinia pestis look like?
Yersinia Pestis is the germ that infected many during the bubonic plague. it was once called pasteurella pestis named in the honor of the pasteur institute, but was later renamed yersinia pestis after Alexandre yersin. Yersinia pestis was carried by flea and rodents and was tranfered to humans. this germ caused many deaths and caused one of the most severe epedemics in the world in history. Yersinia pestis (formerly Pasteurella pestis) is a Gram-negative rod-shaped bacterium belonging to the family Enterobacteriaceae. It is a facultative anaerobe that can infect humans and other animals. Human Y. pestis infection takes three main forms: pneumonic, septicemic, and the notorious bubonic plagues. All three forms have been responsible for high mortality rates in epidemics throughout human history, including the Black Death (a bubonic plague) that accounted for the death of at least one-third of the European population in 1347 to 1353. Recently Y. pestis has gained attention as a possible biological warfare agent and the CDC has classified it as category a pathogen requiring preparation for a possible terrorist attack. Yersinia pestis bacteria -- the organism responsible for plague -- can grow with or without oxygen. Animals that are known to carry the bacteria include rats, prairie dogs, and fleas. During an outbreak, the bacteria can survive for months in cool, moist conditions, such as a rodent hole. Approximately 10 to 20 people in the United States develop an infection each year from flea or rodent bites.
How many people died from yersinia pestis?
Actually,around 100,000 people died in London, let alone for the rest of the United Kingdom. Whatever the amount is it was more than 100,000 people. (Source: http://www.channel4.com/history/microsites/H/history/plague/experts.html)
How do you get the plague?
One gets plague when he/she is bitten by infected rats or fleas.You got it through a flea that has bitten a rat whos blood is infected with many bad bacteria, like yersinia pestis.
Why did they burn the people in the black death?
To kill the remaining living viruses and bacteria.
When did The Black Occur?
Black Plague or Bubonic Plague started in Europe around 1347, when the rats came to town. They carried a flea which carried a bacteria called yersinia pestis. There were many out breaks of this disease. 1300's to late 1600's.
How many victoms of yersinia pestis to 2011?
Although there have been isolated incidents in Prarie Dog populations and in Human populations in India and Africa, there have been no significant outbreaks of Plague. Improved sanitation has led to fewer rats who carry the fleas that are infected with the bacteria.
What yersinia pestis attacks?
The Black Death was one of the deadliest pandemics in human history. Yersinia pestis is a Gram-negative rod-shaped bacterium belonging to the family Enterobacteriaceae. Onset is marked by a high fever. Many victims complain of a general feeling of malaise accompanied by pain or tenderness in the lymph nodes, which may swell forming buboes, a characteristic of Bubonic Plague. Symptoms progress to include convulsions, shock, and hemorrhagic changes in the skin. Cyanosis from the necrotizing pneumonia produce the dark skin at the extremities lending to the term "black death."
How many people died during these epidemics?
The Black Death was one of the most devastating pandemics in human history, resulting in the deaths of an estimated 75 to 200 million people and peaking in Europe in the years 1348-50 CE. Although there were several competing theories as to the etiology of the Black Death, analysis of DNA from victims in northern and southern Europe published in 2010 and 2011 indicates that the pathogen responsible was the Yersinia pestis bacterium, probably causing several forms of plague.
What caues the plague?
"The plague" doesn't mean too much as many diseases and even animals - like locusts - have been said to cause plagues. But - There is debate as to what the famous "black death" was as the normal form of bubonic plague, which is what it has traditionally been associated with, does not normally behave as the disease did during that time. Yersinia pestis is the bacillus that causes plague.
What is Bubonic Plague?
It was a deadly disease carried by fleas on a rat or rodent. it was common in the black death. it took over 200 million lives. It is an infection of lymphatic system. it is contagious and some symptoms include diarrhea, chills , fever, barfing, ETC.Bubonic plague is the best-known manifestation of the bacterial disease plague, caused by the bacterium Yersinia pestis (formerly known as Pasteurella pestis). Bubonic Plague is often used synonymously for plague, but it does in fact refer specifically to an infection that enters through the skin and travels through the lymphatics, as is often seen in flea-borne infections. Bubonic Plague kills about 50% of infected patients in 4-7 days without treatment. The Bubonic plague is believed by many to be the Black Death that swept through Europe in the 1340s.in more simpler words, the bubonic plaque is a disease that in the 1340s killed many people. some of the symptoms are vomiting and buboes(egg-sized swelling or bumps).Bubonic plague is the best-known manifestation of the bacterial disease plague, caused by the bacterium Yersinia pestis (formerly known as Pasteurella pestis).
