Antibiotics - Mechanisms of Action (Classification) and Antibiotic Resistance

Hey Friends,

Antibiotics are a specific type of medicine directed against bacteria. Penicillin was the first available antibiotic on the market. There are multiple antibiotics such as Beta Lactams, Tetracycline or Rifamycin. All have different mechanisms of action. The overuse of antibiotics can promote mutations in the bacterial genome. When the mutation alters the protein structure of one of the antibiotic targets (enzymes e.g. Transpeptidase) by chance this can lead to antibiotic resistance. Multiresistent germs are extremely dangerous and we have to find new antibiotics to prevent to fight them but also be more responsible with the antibiotics we have!

Thank you for that! Your videos have aided me in my writing. I've used your channel to start my research in a lot of areas regarding biopsychology.

Thank you for your time!

This is so helpful for my medical microbiology exam

Bacteria: What doesn't kill me, makes me stronger.

Bacteriophage: Nah, I'd win. 🗿

That's an amazing and simplistic explanation of the action of antibiotics and mainly #antibioticreistance

[amandaallen]

Good overall explanation, however please may I suggest an edit. Antibiotics make bacteria unstable not instable. This is the action that kills or severely disrupts bacterial proliferation.

Alhm du lillahh.. Allahh has given a very good explanation method👍👍👍👍

I have never taken an antibiotic . I’ve always used superfoods etc to boost my immune system. Im sure I will need antibiotics at some point. It’s important to boost your immune system by eating as natural as possible, exercise and sleep ( not over sleep though unless you r sick. This has kept me from getting sick or if I am sick, it’s not long. I also take a multivitamin every day. My mom was a vitamin believer and always gave us a multivitamin every day. My brothers and parents were pretty healthy . I am blessed and hopefully can help other people with this info. I believe in antibiotics if they r needed. Bacteria infections r no joke.

¡Gracias! Excellent video, a hug from Honduras...

Thank you so much. Explained very well👏👏

[pitkamatka]

Great video! 💯 I'm just wondering whether cell wall synthesis disrupting antibiotics work on gram negative bacteria which have another layer of protection outside their cell wall. Also do you know, how do bacteria take up antibiotics that target their protein synthesis? 🤔

It's interesting how you pronounce synthesize perfectly, yet you pronounce synthesis as "thinthethis".

You and “synthesis”
