Hello everyone in this question we will be discussing about different shapes and arrangement of bacterial set.
00:07
The bacteria can exist in 0 .2 to 2 micrometer and 0 .5 to 5 .5 .0 micrometer in length.
00:21
These can be bacillus that is rod shaped and these are mostly the single rods and they can exist in diplovacilli form that is like the pairs form or they can exist in the chain form that is the streptobacilis and these can be gram positive or can be gram negative the gram positive the gram positive basilai are are claustrodium, claustridium, cornebacterium, bacillus etc.
01:08
And gram negative are salmonella, e coli, sigilla etc.
01:16
And this gram positive and gram negative can be distinguished by the gram staining.
01:25
In which first of all the stain is provided to the cell that is the crystal violet stain and once the strain is removed by the decolorizer the ones which still incorporate the stain are the gram positive and which decolorizes are the gram negative and then we have caucus shaped that is spherical or ovoid and these caucus can exist in pairs and are known as diplocoquyre.
02:03
Or they can be present in chain form and can be streptopokide.
02:12
Or they can be in cube -like form and are known as tarsinic.
02:20
Or they can be grape -lides and are called stefylococide...
