Types of Microorganisms
Most microbes are unicellular and small enough that they require artificial magnification to be seen. However, there are some unicellular microbes that are visible to the naked eye, and some…
VIRUSES
Viruses are the smallest of all the microbes. They are said to be so small that 500 million rhinoviruses (which cause the common cold) could fit on to the head…
How do bacteria reproduce?
Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium…
Bacteria
Bacteria are single celled microbes. The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the…
Flagella Stain
Flagella are too thin to be visualized using a bright field microscope with ordinary stains, such as the Gram stain, or a simple stain. A wet mount technique is used…
Capsule Stain
Capsule stain is a type of differential stain which uses acidic and basic dyes to stain background & bacterial cells respectively so that presence of capsule is easily visualized. Capsule…

Gram Staining: Principle, Procedure, Interpretation, Examples and Animation
Gram Staining is the common, important, and most used differential staining techniques in microbiology, which was introduced by Danish Bacteriologist Hans Christian Gram in 1884. This test differentiate the bacteria into…
Difference Between Light Microscope and Electron Microscope
Microscopes come in a variety of sizes, each with its specific suitability. The most common categories are the electron microscope and the light microscope. Each of these microscopes possesses distinct…
The Species Concept in Microbiology
The number of species of bacteria and archaea is surprisingly small, despite their early evolution, genetic, and ecological diversity. Judging Species in an Asexual Context Biological classification: The hierarchy of…
