Yersinia pestis Yersinia pestis (formerly Pasteurella pestis) is a Gram-negative, rod-shaped coccobacillus, a facultative anaerobic bacterium that can infect humans and animals.It causes the deadly disease named plague.. pestis is a nonmotile, rod-shaped, facultative anaerobe with bipolar staining (giving it a safety pin appearance). Similar to other Yersinia species, it tests negative for urease, lactose fermentation, and indole.

- Bubonic plague is one of three types of bacterial infection caused by Yersinia pestis. Three to seven days after exposure to the bacteria flu like symptoms develop. This includes fever, headaches, and vomiting.Swollen and painful lymph nodes occur in the area closest to where the bacteria entered the skin.lague is believed to be the cause of the Black Death that swept through Asia, Europe, and Africa in the 14th century and killed an estimated 50 million people. This was about 25% to 60% of the European population. Because the plague killed so many of the working population, wages rose due to the demand for labor.

Plague Yersinia pestis bacteria can cause three different types of plague: bubonic, septicemic, or pneumonic. In bubonic plague, the most common form, bacteria infect the lymph system and causes it to become inflamed.(The lymph or lymphatic system is a major component of your body's immune system. The organs within the lymphatic system are the tonsils, adenoids, spleen, and thymus.).his is the most serious form of plague and occurs when Y. pestis bacteria infect the lungs and cause pneumonia. 1  You get primary pneumonic plague when you inhale plague bacteria from an infected person or animal. 2  You usually have to be in direct or close contact with the ill person or animal.

- Yersinia pestis: The bacteria that causes the bubonic plague which in the year 541 (as the Black Death) and later in the Middle Ages decimated Europe.The effects of the plague are described in the nursery rhyme We all fall down... pestis mainly infects rats and other rodents which are the prime reservoir for the bacteria. Fleas are the prime vectors carrying the bacteria from one species to another. They bite rodents infected with Y. pestis, then they bite people and so transmit the disease to them.

In rare cases, Yersinia pestis bacteria on a piece of contaminated clothing or other material used by an infected person can enter through an opening in your skin.auses of Bubonic Plague: Yersinia Pestis. Yersinia pestis bacteria are usually only found in certain parts of the world, such as Africa, Asia, and South America.

Publications The most common source of Y. enterocolitica infection in humans is pork (raw or undercooked) and pigs are considered the main carrier. Other strains of Yersinia are also found in many other animals including rodents, rabbits, sheep, cattle, horses, dogs and cats.ther species of Yersinia affecting humans are Y. pseudotuberculosis, which causes an illness similar to Y. enterocolitica, and Y. pestis which causes plague. Yersinia are hardy bacteria that can survive in adverse conditions like refrigeration and environments low in oxygen.

Plague Overview. Plague is an infectious disease caused by bacteria called Yersinia pestis. These bacteria are found mainly in rodents, particularly rats, and in the fleas that feed on them. Other animals and humans usually contract the bacteria from rodent or flea bites.Historically, plague destroyed entire civilizations.sually, you get bubonic plague from the bite of an infected flea or rodent. In rare cases, Y. pestis bacteria, from a piece of contaminated clothing or other material used by a person with plague, enter the body through an opening in the skin.

Yersinia pestis Like Y. pseudotuberculosis and Y. enterocolitica, Y. pestis is host to the plasmid pCD1. In addition, it also hosts two other plasmids, pPCP1 (also called pPla or pPst) and pMT1 (also called pFra) that are not carried by the other Yersinia species.. pestis was discovered in 1894 by Alexandre Yersin, a Swiss / French physician and bacteriologist from the Pasteur Institute, during an epidemic of plague in Hong Kong. Yersin was a member of the Pasteur school of thought.

- Back to TopCauses. Plague is caused by the bacteria Yersinia pestis. Rodents, such as rats, carry the disease. It is spread by their fleas. People can get the plague when they are bitten by a flea that carries the plague bacteria from an infected rodent. In rare cases, you may get the disease when handling an infected animal.

- It infects the host by sticking to the cells of the host using trimeric autotransporter adhesins (TAAs). The genus Yersinia includes 11 species: Y. pestis, Y. pseudotuberculosis, Y. enterocolitica, Y. frederiksenii, Y. intermedia, Y. kristensenii, Y. bercovieri, Y. mollaretii, Y. rohdei, Y. aldovae and Y. ruckeri.ecause Yersinia species are siderophilic (iron-loving) bacteria, people with hereditary hemochromatosis (a disease resulting in high body iron levels) are more susceptible to infection with Yersinia (and other siderophilic bacteria). In fact, the most common contaminant of stored blood is Y. enterocolitica.

The culprit behind the Black Death was causing minor infections for years before it turned deadly The Yersinia pestis bacterium causes both bubonic plague, a form of the disease you get from a flea or rat bite, and pneumonic plague, a respiratory infection you get by inhaling the bacteria. Bubonic plague kills via a deadly blood infection, while pneumonic plague causes a fatal pneumonia. Now, scientists have uncovered the steps that led the ancestor of Y. pestis to evolve into the deadly pathogen that causes pneumonic and bubonic plague.

Plague (Yersinia Pestis) People who have bubonic or septicemic plague can also develop Y. pestis infection in the lungs. Symptoms include high fever, chills, headaches, chest pain, rapid breathing, severe shortness of breath and cough that might bring up blood. Without proper treatment, the disease can quickly lead to death.

- Plague is a zoonotic disease caused by the gram-negative bacteria Yersinia pestis. It is endemic (naturally occurring) on all continents except for Antarctica and Australia.neumonic plague can also develop secondary to the other types of plague and occurs when Y. pestis infects the lungs. Once in the lungs, Y. pestis is contagious and can spread to others through respiratory droplets, causing primary pneumonic plague.

Yersinia enterocolitica Y. enterocolitica infection causes the disease yersiniosis, which is a zoonotic disease occurring in humans, as well as a wide array of animals such as cattle, deer, pigs, and birds. Many of these animals recover from the disease and become asymptomatic carriers.ersinia enterocolitica is a Gram-negative bacillus-shaped bacterium, belonging to the family Enterobacteriaceae.

Yersinia Pestis Bacteria Transmission occurs most often through the bites of infected fleas or rodents -- symptoms tend to appear one to six days later. Yersinia pestis are the bacteria that cause plague. They can infect humans, rodents, and ectoparasites (such as fleas and lice).nce infection with Yersinia pestis bacteria has been confirmed, the patient is hospitalized, isolated, and treated with antibiotics.
