Harmful Microorganisms

Microorganisms are harmful in many ways. Some of the Microorganisms cause disease in humans, plants and animals these disease causing microorganisms are called Pathogens. Some Microorganisms spoil food, clothing and even leather.

They can also get transmitted by direct contact with an infected person or carried through an animal they spread from the infected persons for example common cold, chicken pox, tuberculosis and many more.
