Why is plague so deadly?

Bacteria that cause the bubonic plague may be more virulent than their close relatives because of a single genetic mutation, according to research published in the May issue of the journal Microbiology. “The plague bacterium Yersinia pestis needs calcium in order to grow at body temperature.

Is a plague?

The plague is a serious bacterial infection that can be deadly. Sometimes referred to as the “black plague,” the disease is caused by a bacterial strain called Yersinia pestis. This bacterium is found in animals throughout the world and is usually transmitted to humans through fleas.

How do plagues start?

Plague is a disease that affects humans and other mammals. It is caused by the bacterium, Yersinia pestis. Humans usually get plague after being bitten by a rodent flea that is carrying the plague bacterium or by handling an animal infected with plague.

How fast did the black plague kill?

The infection takes three–five days to incubate in people before they fall ill, and another three–five days before, in 80 per cent of the cases, the victims die. Thus, from the introduction of plague contagion among rats in a human community it takes, on average, twenty-three days before the first person dies.

If Y. pestis infects rats, the bacterium can pass to fleas that drink the rodents’ blood. When a plague-stricken rat dies, its parasites abandon the corpse and may go on to bite humans. Because of rats’ role in modern plagues, as well as genetic evidence that medieval plague victims died of Y.

How does bubonic plague kill you?

Summary: Yersinia pestis, the deadly bacterium that causes bubonic plague, kills by cutting off a cell’s ability to communicate with other immune system cells needed to fight off the bacterial invasion.
