Yersinia pestis and the Plague The infectious disease known as “the Plague” is spread by a bacterium classified as Yersinia pestis, which is usually transmitted in the bites of fleas or infected animals or people. Infectious Disease: Signs and Symptoms The plague has three different forms: Bubonic, Septicemic, and Pneumonic. The signs and symptoms of the bubonic plague usually include fever, headache, chills, and weakness and one or more swollen, tender and painful lymph nodes. A flea will typically
The Plague that Keeps on Giving throughout time It has been several decades since our last major pandemic, but for the most devastating pandemic in history was the bubonic plague. The bubonic plague is a bacterium, Yersinia pestis, a disease that affects humans and other mammals. This bacterium disease attacks the lymph nodes that are located throughout the body. Swollen lymph nodes may be a sign that the body is dealing with an infection. The largest groupings are found in the neck, armpits, and
Yersinia pestis and the Plague Jin You MMI 133 Dr. Judith Gnarpe One organism that commonly causes diseases in humans is Yersinia pestis. This bacterium is the causative agent of the infamous bubonic plague, primary septicaemic plague, and primary pneumonic plague. Y. pestis was first discovered by Shibasaburo Kitasato and Alexandre Yersin, but due to Yersin’s description of the bacteria being more accurate, this bacterium was named after him (3). There are still disputes going on for who had correctly
Yertinsa pestis, or Black death was one of the worst natural disasters in history. It killed a worldwide count of 155-220 million people. It is believed to have been one of the first cases of biological warfare when the Mongols catapulted the dead bodies infected with Yersinia Pestis over the city walls, into the city of Caffa, Crimea, an area which they were at war with.. Yersinia pestis started in Asia The bubonic plague was spread by fleas that attached themselves onto rats which spread through
The “Plague” is the name given to any disease generated by the bacterium Yersinia Pestis. The Plague is treated as one of the few history developing diseases, executing hundreds of million of people in the concluding 1,500 years. The early considerable pandemic developed in the 6th century AD. It was established in Africa and advanced to the integrated Mediterranean basin. Assessments of this pandemic alone out the death expense at around 100 million, helping to devote to the fall of the Roman Empire
The Middle Ages were a very dark time, education became very unimportant and people were forced to live in very close quarters and, consequently, hygiene was atrocious and it made the perfect place for Yersinia Pestis to thrive. Yersinia Pestis is the virus responsible for the Black Death, a deadly disease that rapidly powered through Europe, killing nearly everyone in its way. The Black Death had many gruesome and scary symptoms that made bystanders sick just watching. Some people were more likely
Yersinia pestis (previously called Pasteurella pestis) is a Gram-negative, rod-shaped coccobacillus, a facultative anaerobic organism that can infect humans and animals. The genus is Yersinia, and it infects both humans and animals. It causes the deadly disease called Bubonic Plague. Bubonic plague is transmitted primarily by the bite from infected fleas; however, transmission can occur by bites or scratches from infected wild rodents and cats, or contact with tissue from infected animals. It is
Yersinia pestis (Y. pestis), a gram-negative, non-motile facultative intracellular bacterium is responsible for the bubonic plague in humans (Smiley 2008). The bacterium uses the Rodent flea Xenopsylla cheopis as a vector to gain entry into a new host. (Butler 2009). The bacterium forms of an aggregative biofilm on the spicules of the proventriculus in the flea (Butler 2009). This blockage on the proventriculus causes the flea to behave as if it is starving continuously biting and try to feed
Identification and Prevention of What Makes Life “Nasty, Brutish, and Short” Plague is caused by the bacterium bacillus Yersinia pestis, and is carried by rodents, fleas, and mammals. Plague takes three forms: bubonic, pneumonic, and septicemic. Bubonic plague affects the lymph glands, while the pneumonic and septicemic forms affect the lungs and the blood. Today, plague can be prevented by antibiotics and strict public health measures. Three methods of controlling carriers involve sanitizing
The Plague and the Yersinia Pestis Bacteria Introduction: The bacteria Yersinia Pestis is the cause of the black plague. Y. Pestis was discovered by Alexandre Yersin in 1849. The plague was the cause of one of the world's most horrific epidemics in the entire world. The plague is an infectious disease that first appeared in 1347 in China and made its way to Asia and then the Black Sea. The Black Plague has caused death to about 75 million lives. The plague is a deadly bacterial infection that can
