The Black Death was a massive plague, named: The Bubonic Plague; which spread through Britain and the rest of Europe in the mid 14th century, killing nearly half of the population; including farm animals, like: sheep, cows and chickens.

From the start to the end of the Black Death, the population decreased by around 1.8 million people. Due to minimal pay, lack of hygiene and nutrition, peasants especially had a tough time defending against the spread of the infectious disease.

What is the name of the bacillus and bacterium that causes the black death?

The bacterium that causes the black death is Yersinia pestis. It is a type of bacillus, which is a rod-shaped bacterium.


When was the black pague?

The Black Death occurred in the 14th century, with the most devastating outbreak happening between 1347 and 1351.


How did the europeans know anthrax wasnt the black death?

Because, Anthrax and the Bubonic plague, also known as Black Death are two different types of diseases. African mammals were often infected with Anthrax, and the spores could have easily reached Europe through air currents. This evidence suggests that Anthrax was present at the time of the Black Death and was responsible for or at least contributed to the great many deaths the plague caused. But whether or not it was the cause of the Black Death, or simply aided the Bubonic Plague in some capacity in making people sick, remains unclear.


Why were the boils from the black death black?

The boils from the Black Death were not black per say, they were the usual blacky purple colour that you get from a heavy bruise (bleeding under the skin). They were hard, painful, burning lumps that usually appeared around the lympth nodes eg, neck, armpits, groin and thighs. Bubonic plague (Black Death) is an infection of the lymphatic system usually resulting from the bite of a flea (from rats in this case). As the disease progresses, the lymph nodes can hemorrhage and become swollen and necrotic (gangrene) hence why the boils are blacky purple to begin with, until they burst and ooze with puss and blood.


How do you make a black hole explode?

The concept of black hole explosions is hypothetical at best and sensationally overrated. The introduction of black hole explosion, promoted by Stephen Hawking and John Wheeler, is basically the calculated event of a dramatic increase in the rate of Hawking emissions upon the onset of black hole death. It would be like a pressure build up in a boiler, except the container is initially able to withstand the bursting event. The notion of black hole death is that eventually the dramatic increase in the rate of Hawking radiation emission reduced the mass of the black hole, and the black hole's energy would evaporate. However, the calculated evaporation time for this type of black hole death is much longer than the current age of the universe at 13.73 ± 0.12 x 109 years.
