My background is in biotech - so I've done a lot of microbiology work. While I appreciate what this video is trying to do, it's grossly misleading. Antibiotic resistant bacteria aren't bacteria that somehow became stronger - in fact ab resistant mutants are overall less fit than their wild-type counterparts. One of the primary mechanisms for this (as was poorly represented in the video) is the loss of proper function in a bacterial enzyme attacked by the antibiotic. Because the bacteria loose the ability to make a functional enzyme, the prodrug becomes harmless. Antibiotic resistance is a real problem, don't get me wrong, but it's important that people understand properly what is happening so that we can solve this real-world threat.
Because it takes a lot of energy for a bacterium to make the chemicals that allow it to break down antibiotics. Non-resistant bacteria can reproduce faster because they aren't diverting their energy into making these chemicals, which are useless in the absence of antibiotics.

Hi can I use your video and put credits?
she describes a problem which has the potential to doom humanity with such a perky voice
+likeastarbaby She said " antibiotic resistance is a global problem for all of us " but she sound too happy about it wtf
How will a resistant bacteria have a selective disadvantage when the antibiotic is not being used?
Because it takes a lot of energy for a bacterium to make the chemicals that allow it to break down antibiotics. Non-resistant bacteria can reproduce faster because they aren't diverting their energy into making these chemicals, which are useless in the absence of antibiotics.
Very Nice :D
Thanks
The true tragedy of the advent of antibiotic resistant bacteria is that the poor fungi that produce these antibiotics are no longer protected.

Yummy
Nerds
just tryna get a good biology grade here
the thing is, why is being a nerd bad? 90% of the time they're the ones getting better grades than us
