What Are Microbes?

Is this a microbe?
Microbe
• A microbe is any living thing that spends its life at a size
visible sometimes only with a microscope. It is too tiny
to be seen with the naked eye. Microbes are the oldest
form of life on Earth. Some types have existed for
billions of years. They may live as individuals or cluster
together in communities. Microbes live in the water
you drink, the food you eat, and the air you breathe.
Right now, billions of microbes are swimming in your
belly and mouth, and crawling on your skin! Don't
worry, over 95% of microbes are good for you.
Microbes include bacteria, viruses, fungi, algae, and
protozoa. These single-cell organisms are invisible to
the eye, but they can be seen with microscopes.

Interesting factoid about micro
organisms
• One cannot catch cold at the North Pole in
winter. Neither can one contract the flu, nor
most of the ailments transmitted viruses and
germs. The winter temperature is so low in
this part of the world that none of the
standard disease causing Micro-organisms can
survive.
