Gram Positive and Gram Negative Bacteria

[jonathanvanname]

For some reason, people are having a difficult time understanding why gram positive bacteria is more receptive to antibiotics than gram negative. Even though gram positive has that thick peptidoglycan layer, it lacks that outer membrane that the gram negative has. Thus, it takes a rather strong antibiotic to fully penetrate the membrane of the gram negative bacteria and to completely thwart its process.

You just saved my life. Thank you for simplifying this concept! You are a great teacher!!

Professor I am a novice biochemist. thanks for your effort. your videos are helping me to achieve the basic of microbiology.

i`m studying for a test tom, it is really helpful and easier than my instructor's handouts.

[abbeykalio]

i just love how you pronounced the bacteria without stress

[allanochoa]

came here not knowing the difference between Gram positive and gram negative bacteria,
and now i am leaving with knowledge of gram-positive and gram negative bacteria :)

You teach way better than my teacher! Thanks for the video

[JensStaschel]

I'm happy that your videos still exist ❤ it's been 6 years

You discussed everything really well and concisely. Thank you so much for this!

This is a VERY basic demonstration of the differences between Gram + and Gram -. tetra-peptides are the cross links between NAG and NAM that make up the peptidoglycan cell wall, Teichoic acid are also found only in Gram + although its function is not well understood. on the other end, lipoteichoic acid, in some bacteria, is made out of 60% wax, which is able to prevent the cell from drying out (making it more difficult or water to escape). As for Gram -, lipopolysaccharide, is made out of sugar monomers covalently bound to the phospholipid bilayer whose hydrophilic head are the endotoxins she was talking about.

Um yes.... I wish I could give you a big hug cause this condensed everything I need to know nicely.

Simplicity at its best in Microbiology !!! Fantastic way to explain it.

[ahmadreza]

Ma, am you have amazing style for explained this
Thank you
Also you bicep and triceps locking so good

[meshalal-harbi]

You just made this so FREAKING easy, thank you!

[ninjastriker]

If i pass my exams today it'll be because of this lecture

[aryasingh._]

What is the difference b/w lipoteichoic and teichoic acid ? Are they same ?

[bhagyashrisamanta]

Why are gram negative bacteria usually much easier to disrupt by sonic oscillation than gram positive bacteria?

[FLM]

Thank you so much. You made this subject 1000x more understandable.

Does anyone know which of the two types is most susceptible to antibodies? I thought it would be gram-positive bacteria because of the thicker peptidoglycan layer and the lack of porins...
