So in the question there is a test performed known as kb test or kirby bayer test which depicts the antibiotic sensitivity.
00:15
So it's a kbior diffusion test.
00:18
It is a diffusion test which is used to check the sensitivity of a particular bacteria.
00:27
Here it is about the staphylococcus epidermis.
00:30
Okay, and the antibiotics that has been used for this kirby bear test are penicillin, then there is novo -biosine and gentamicine.
00:46
Okay, so the question is, what if this antibiotic diffusion test or the sensitivity test is been used to check the sensitivity against e.
00:59
Coli? so this kirbyware diffusion test also called as kb diffusion test is used to check the antibiotic sensitivity and also to check the inhibition by any particular bacteria.
01:24
Inhibition by any particular bacteria.
01:28
Okay.
01:30
So generally where does this epidermis is found as epidermis is.
01:35
The normal part of a skin flora.
01:39
So as epidermis, it is a gram positive bacteria, gram positive bacteria which is generally found on the skin flora.
01:53
And to talk about equally, equally is gram negative bacteria, which means it will have an additional cell wall layer and generally found in the gut of humans.
02:08
So when there is a test being performed using e.
02:12
Coli and this various antibiotic and the comparison has been done then to take about the first antibiotic penic.
02:24
This penicillin will act upon the cell wall synthesis.
02:29
So it is going to act upon the inhibition of cell wall synthesis.
02:33
And therefore what will happen the s epidermis is going to be more sensitive.
02:42
So what could be the reason that s epidermis is more sensitive compared to aecoly? so as i mentioned as the ecoli is gram negative one, it has an additional cell wall layer which protects the e.
03:02
Coli cell.
03:03
Means it is going to give the additional protection.
03:06
Therefore, epidermis is more sensitive to penicillin compared to equally...
