Differential staining: Gram staining & Acid-fast staining technique
As name indicates these technique imparts different colour to different bacteria or bacterial structure. It allows us to differentiate between different kinds of bacterial cells or different parts of a bacterial cell. Differential stain technique includes the following technique:- 1. Gram staining 2. Acid Fast staining/Zeihl-Neelsen staining 3. Albert’s stains 1. Gram staining The most …

Mycobacterium leprae: Types of Leprosy, Pathogenesis & Epidemiology of leprosy
Leprosy is a chronic bacterial disease and it is caused by Mycobacterium leprae. Leprosy was first observed by Hansen in 1868 so also known as Hansen disease. It mainly affects the skin, eyes, nose and peripheral nerves. It is a gram-positive acid-fast bacteria for which 5% percent sulphuric acid is used for the decolorization after …

Classification of Bacteria on the basis of Nutrition, oxygen requirement, growing temperature & pH
Bacteria are prokaryotic organisms that do not contain chlorophyll. They are unicellular and do not show true branching. They differ from eukaryotes in not having a nuclear membrane, a nucleolus, and cell organelles like mitochondria, golgi apparatus and endoplasmic reticulum. They have a single circular chromosome. For growth and multiplication of bacteria, they require nutrition …
