and politics. The black plague is known for causing a huge impact on Europe however that’s not where the disease originated from. (Haensch) The Black Plague started in China in 1334. The plaque was a etiologic agent or type of bacterium known as Yersinia pestis.

true that the black plague bacterium Yersinia Pestis even after so many years is still thriving in some animal carriers today like wild dogs, rodents, etc.? Relationship-Analyzing: 1. What is the connection between HIV/AIDS and the plagues that took millions of lives in the past? 2. Was there any connection between the increasing small rodent population and the rising number of “Black Plague” plague deaths at the same time? 3. Does the plague bacterium Yersinia Pestis cause flea infestation in rodents

outbreak of plague. Plague is a very deadly bacterial disease. It has been a recurring force that has wiped out much of the world’s population during it’s outbreaks. The bacteria that is responsible for one of history’s most deadly diseases is Yersinia pestis. Yersinia pestis first infectes a rat. The rat is then the host for a flea. The flea feeds on the blood of the rat which is infected by the bacteria. For a reason still unknown today the bacteria started multiplying in the flea blocking it 's stomach

Black Death plague because of the symptom, gangrene, which cause blackness of the extremities. The bubonic plague is an infectious-bacterial disease which classifies as proteobacterial, the pathogen Yersinia pestis is responsible for causing the bubonic plague as well as pneumonic and specticemic, Yersinia pathogen is a gram negative, rod shaped and non-spore forming bacteria. The bubonic plague is the most devastating pandemic in human history it has estimated to kill approximately 75 to 200 million

plague claimed the lives of 75-200 million people before peaking in Europe during the mid-14th century. According to researchers in a new study, now published in the Journal of Medical Entomology, the bacteria is believed to be an ancient strain of Yersinia pestis, a bacillus that was carried by fleas on rats. The bacteria were discovered on the proboscis of the old flea, as well as in the flea’s rectum. "Aside from physical characteristics of the fossil bacteria that are similar to plague bacteria

Middle Aged Europe was an expansive period of time and marked the beginning of the Renaissance. A period of time in which reformation of important social aspects such as religion, education, and the arts was active and advancing at a rapid rate. Significance of intellectual inquiry and the belief in the human mind helped shape many new philosophical ideas and theories that would be spoken about for hundreds of years. This increasingly advanced period of time was quickly halted around the middle of

symptoms, and the treatment, one can tell that the plague was horrific. The bubonic plague is a highly infectious disease that affects the lungs and lymph nodes. The plague is caused by a gram-negative, facultative anaerobe bacterial species called Yersinia pestis (“Bubonic Plague”). This same parasite can cause tuberculosis (Scogna). Bubonic plague is one of three forms of the plague. The other two forms are pneumonic and septicemic (“Plague”). The pneumonic form is very contagious; the

All types of the plague are derived from the bacteria Yersinia pestis, which is not only found in the United States, but also all around the world (“Frequently Asked Questions”). This bacteria is very specific to the Bubonic Plague and is used in scientific tests to determine whether or not a human has the disease. The Yersinia pestis bacteria was discovered by Alexander Yersinia in 1894 and “is a gram negative, rod-shaped, facultative anaerobic bacterium” (Tucker)

Leading up to the Black Plague in Europe, there were many other plague outbreaks around it, such as the one in the East Roman empire in the sixth century. In 1348 the Bubonic Plague was introduced to the European nations from a type of bacteria called Yersinia pestis which can be carried by fleas that are on the backs of rats,

main types of existing plagues: Bubonic plague, Septicemic plague, and Pneumonic plague. All three are caused by the bacterium named Yersinia pestis that is found in infected rodents and their fleas (CDC, Plague home page paragraph 1). The oriental rat flea, or Xenopsylla cheopis, is the primary vector, but handling infected animals can also spread plague. Yersinia pestis is a gram-negative bacterial
