|+||Bubonic plague: The most common form of the plague, named for the characteristic buboes -- buboes are enlarged lymph nodes ("[[swollen glands]]") -- in the groin which are usually very tender and painful. [[Lymph nodes]] may be similarly affected elsewhere such as in the armpits and neck. Common but less specific features of the [[disease]] include headache, fever, chills, and weakness. |
|+||The bubonic plague is caused by [[bacteria]] called Yersinia pestis. The [[bacteria]] are transmitted from infected rats to the oriental rat flea to people. (The rats are a "reservoir" for the disease. The fleas are the "vectors" that carry the bacteria from the rat reservoir to the human host.) |
|+||The bubonic plague caused the "black death" (the black plague) characterized by gangrene of the fingers, toes, and nose.|
