Hello students, the primary types of staining techniques used by the microbiologists are as follows.
00:08
The first one is simple staining.
00:13
Simple staining.
00:16
In simple staining, only one type of dye is used to color all the cells in a microbial sample.
00:25
This staining helps to visualize the basic shape, size and arrangement of microorganisms.
00:33
The examples of dyes that are used for simple staining are crystal violet, crystal violet, methylene blue, methylene blue and saffronin, and saffronin.
00:58
The next type is differential staining.
01:04
Differential staining.
01:08
Staining.
01:09
In this method, multiple dyes are used.
01:13
Here single dye is used.
01:17
Here multiple dyes are used to differentiate between the microorganisms and different parts in them.
01:31
These techniques help to identify specific characteristics such as cell wall composition or cellular structures.
01:40
Two examples for differential staining are gram staining, gram staining.
01:52
This technique helps to differentiate between gram positive and gram negative bacteria based on the differences in their cell wall composition.
02:06
It involves the use of crystal violet, iodine, alcohol or acetone decolorization and a counter stain like saffronin.
02:17
The next type is acid fast staining.
02:24
Acid fast staining.
02:27
It is used to identify acid fast bacteria.
02:34
Acid fast bacteria such as mycobacterium species.
02:41
These bacteria have a waxy outer layer that makes them resistance to regular staining method...
