Introduction

What is a microbe? A microbe or microorganism is a member of a large, extremely diverse, group of organisms that are lumped together on the basis of one property -the fact that, normally, they are so small that they cannot be seen without the use of a microscope. The word is therefore used to describe viruses, bacteria, fungi, protozoa and some algae
