Yersinia

“The Black Death, caused by the Yersinia pestis bacterium, first exploded in Europe between 1347 and 1351.” (Pappas) It consisted of three different plagues; The Bubonic, Septicemic, and Pneumonic plagues. It was first noticed when Genoese trading ships were docked at the Sicilian port of Messina arriving from the Black Sea. People waiting for the ships to arrive were astonished at the scene left on the ship. A big percentage of the sailors were dead. Others that were still alive, didn’t have much

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 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

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

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 a large area. The plague infected the rats and when the rats died, the fleas would attach on to humans. The plague quickly spread all over the world. Yersinia pestis infects the lymphatic system, which is a network

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

Yersinia pestisis is a highly infectious, Gram negative bacillus that is transmitted to humans usually through the bite of infected fleas. [1]. Yersinia pestisis reaching the respiratory tract results in pneumonic plague, which is also highly contagious due to its airborne transmission. [1]. Pneumonic plague usually causes fatality in “less than three days if no treatment is administered.” [1]. “Plague has been one of the deadliest bacterial infections in human history, causing millions of deaths

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

Epidemiology Yersinia Pestis is found in many different countries. It usually effects people in the tropical, subtropical, and warmer temperate climates. This plague has effected countries in Africa, the former Soviet Union, the Americas, and Asia. Since the 1990’s most human cases have been seen in Africa (Plague). The three most common countries it effects are Madagascar, the Democratic Republic of Congo and Peru. The spreading of this disease goes with the delivery of rodents it infects, which
