How MRSA Was Made

This is an awesome slide show on how MRSA, the antibiotic resistant strain of Staphylococcus Aureus, came to be – written at a “3rd grade” level…

Once upon a time there was a bacterium...

Development of resistant Staphylococcus aureus over time

I sort of had an idea before of how this worked, but I’m happy for the extra detail. This is the perfect way to explain something as complicated as how bacteria evolve to fight off antibiotics. And, although the author doesn’t mention it, it is a perfect example of real evolution in action.

I love stuff like this, because it is so hard to see evolution in action in complex animals – it takes way longer than we are alive – but in bacteria and viruses, it happens all the time and it happens fast.

I also hate stuff like this, cause it really blows when our medicine stops working… but, life will find a way – even if that way is defeating us when we try to stomp it out.

Come on MRSA, can’t we just get along?
