Bubonic plague Plague 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.he three types of plague are the result of the route of infection: bubonic plague, septicemic plague, and pneumonic plague. Bubonic plague is mainly spread by infected fleas from small animals. It may also result from exposure to the body fluids from a dead plague infected 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.. Y. 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. Transmission of the plague to people can also occur from eating infected animals such as squirrels.

The Black Death And so it happened with the “Black Death”—a bacteria carried by flea-ridden rats. The bubonic plague is estimated to have killed up to half the population of Europe—about 25 million people. Although they didn’t know what caused the disease, the Europeans had no trouble figuring it out—it had to be the Jews!

Plague Causes. Plague is caused by the bacteria Yersinia pestis. Rodents, such as rats, carry the disease. It is spread by their fleas. People can get plague when they are bitten by a flea that carries the plague bacteria from an infected rodent.

What Is the Bubonic Plague? When an animal or person is infected with Yersinia pestis, the bacteria affect the lymph system, causing the characteristic symptoms. If bubonic plague is left untreated, plague bacteria can quickly multiply in the bloodstream, causing septicemic plague. The bacteria could also progress to the lungs, causing pneumonic plague.

Bacteria That Causes the Bubonic Plague Usually, the bacteria that causes the bubonic plague is contracted when someone is bitten by an infected flea or rodent. In rare cases, it is possible for a piece of contaminated clothing or other material used by an infected person to transmit bacteria through a cut or other opening in your skin and infect you.ubonic plague is rarely spread from person to person. Yersinia pestis bacteria begin to multiply once they reach the lymph nodes. (The lymph or lymphatic system is a major component of your body's immune system.

- Plague disease is a severe illness that can result in pneumonia, swollen glands, blood infection, and death. It is caused by bacteria named Yersinia pestis. Plague killed millions in the 14th century and was called the Black Death. In 1900, there was an outbreak of plague in San Francisco caused by infected rats brought by a ship.

The Black Death: Bubonic Plague The Black Death: Bubonic Plague. In the early 1330s an outbreak of deadly bubonic plague occurred in China. The bubonic plague mainly affects rodents, but fleas can transmit the disease to people. Once people are infected, they infect others very rapidly. Plague causes fever and a painful swelling of the lymph glands called buboes, which is how it gets its name. The disease also causes spots on the skin that are red at first and then turn black.

Rat Diseases It is true that the black rat did host a species of rat flea that harbored the Yersinia pestis bacteria that causes plague. There were, however other factors involved in the “perfect storm” that was the plague pandemic which helped make it so deadly, a set of circumstances that is unlikely to be seen again.

What Is the Treatment for Plague? Plague Disease Causes. The bacteria (Yersinia pestis) that cause plague can be transmitted from a host such as a rat to a human through the bite of an animal or insect (such as a flea). These bites transport the disease. Bubonic plague: The bacteria that cause plague can thrive and grow in the flea's esophagus. 2  This crowding of bacterial growth prevents food from entering the flea's stomach. 3  To overcome starvation, the flea begins a blood-sucking rampage.
