What are the three different types of plague that result from the Yersinia pestis? You don't have to, but it would be immensely appreciated if you described them!

Explanation:

Bubonic plague - it 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. One to Seven days after exposure to the bacteria,flu-like symptoms develop. Symptoms include fever,headaches and vomiting. Swollen and painful lymph nodes occur in the area closest to where the bacteria entered the skin.
