Black Death was caused by fleas. They carried Yersinia pestis bacterium.
Yersinia pestis
typhus
The main carriers of the bubonic plague were fleas and rats. The fleas got it from the rats when they bit them. When the rats died, the fleas went to new hosts, bit them, and gave them plague in the process. Usually the new host was another rat, because rats hang together, but sometimes there was no rat to go to, and the fleas went to whatever animal they found.
The Bubonic Plague, which gave birth to the Black Death.
The Black Death originated in fleas. The fleas then moved onto rats. The rats got carried around on ships to different countries and continents, thus spreading the black death around the world. The Black Death began to spread from fleas that bit mice and rats that were infected with a the black death. The fleas would swell from the infected blood they took in and vomit it out. The fleas bit any warm blooded creature they could find which resulted in the spread of the Black Death.The bubonic plauge was caused by the infected fleas whose resevior is rats and the bacteria causing plauge is called yersinia pestis.^_^The Black Death spreads by people who had it and lived in a packed town. The black death also followed the trail of traders, merchants and travellers over land and sea. The the primary source of infection was from bacteria spread by fleas on rats.First of all the was two type of plague, these were bubonic and pneumonic plague. Bubonic was spread in the bloodstream of flea's. When the flea's had the plague inside them they become hungry and bite rats, the rats then die, however the plague blocks up the flea's stomach which makes them bite the humans, this make the humans catch bubonic plague. If you caught bubonic plague you had a 70% chance of death but it was better if you caught it in winter because there were not as many flea's around in winter compared to the other seasons. Bubonic plague would kill you in about 4-7 days. Bubonic plague was mainly spread by trader's via trade routes and even by invader's and invading mongols. The mongols even infected the trader's of Italy and gave them the terrible disease. Now I will talk about the second type of plague, this is called pneumonic plague, the pneumonic plague was spread from central Asia to the whole of Europe by breathing and sneezing. The terrible thing about this plague is that it killed everyone who caught it with 2-3 days. The Black Death was a terrible plague and killed millions and changed the life of others who survived.----------------------------------------------------Mainly by ratsIt was usually through fleas which were attached to rats on ships coming from Asia. Then the fleas attached to humans and spread the disease to them.Fleas living on black rats. Fleas, and the fleas spread on rats. Close quarters living (Castles, cramped city's due to walls) helped make it spread even faster.The people of the middle ages thought that it was the rats and other furry animals that carryed the plage so they killed them all. However it was the flees on the rats and animals that carryed the plage.It was highly contagious, many people got it from physical contact, but some may of got it airbourneThe black death was caused by flees from rats getting on or in your clothes. When they bite you a disease spreads through you whole body. The side affects were vomiting, black blood bubbles on your body, fever, swelling of lymph nods on your body.The black death, also known as the bubonic plague, was spread by fleas, who would infect people with a bacterium, Pasturela pestis, when they bit. The fleas were spread by rats.
the rats came from Asia and the rats tranfred it to fleas and the fleas gave it to the white people
One of the first symptoms, was large bulbous boils that occured on the body
Roaches gave deadly disease to rats, rats gave to people, people gave to other people. The European plague was called the Black Death because lymph nodes would become swollen and then die. They would be black so this plague was called the Black Death for this reason. Rats carried fleas, the fleas carried the microbe that caused black death in them and when they bit they passed it on to people.
Rats in this time carried the Black Plague also known as the beubonic plague. My History teacher gave me this vid link "http://www.youtube.com/watch?v=rZy6XilXDZQ" it's about the black plague and they also do other history songs.
The Bubonic Plague originated in China. It was spread by the fleas carried by rats going aboard ships and they were transported to Italy, Greece and France, when the rats left the ships entering cities and gave us the Bubonic Plague. The Pneumonic Plague was spread by humans breathing in infected people's germs, this type of Plague was more deadly, but it would have been the same symptoms.
People who contracted the Bubonic plague (the Black Death) got black buboes in their armpits and groin area before they died.
It is believed to be the rat.However, there is new, recent evidence that the black plague was actually caused by anthrax and spread by humans, not bubonic bacteria spread by rats as previously thought. See the related question below for more information.
It killed the rats and fleas that carried the plague and gave it to people.
Pandemic...is was widespread across continents and countries and not just localized like an epidemic. The Black Death, also known as the Black Plague and Bubonic Plague, was a catastrophic plague that began in Asia and then was spread into Europe between 1346 and sporadically until the late 1700's; peaking between 1347-1351. It killed tens of millions of Europeans. It was caused by a bacterium that was carried by the fleas of rats who gave it to humans when the rats died and the fleas looked for a new host.
