Plague (black death) is caused by.
1 bacteria
2 virus
3 protozoan
4 fungi
Explanation:
Plague is an infectious disease that affect animals and humans. It is caused by the bacterium Yersinia pestis. This bacterium is found in rodents and their fleas occurs in many areas of the world including the United States. Yersinia pestis is easily destroyed by sunlight and drying.
