Mike the Mad Biologist found this one:
There's a brand new antibiotic waiting in the wings. It's called Platensimycin, and it's effective against Staphylococcus Aureus in mice. It works by inhibiting the production of fatty acids in the bacterium, by targeting FabF/B condensing enzymes (whatever they are), and this eradicates the infection. It's broad spectrum, so it looks as if it just might work on Methicillin-resistant Staphylococcus Aureus (MRSA), as well as Vancomycin-intermediate S.Aureus.
They're still only in the animal testing stage, so there's a long way to go before it comes on line. If it's as good as tests indicate, then it's fantastic news for world health. It's like Gandalf and the Riders of Rohan coming over the summit at the Battle of Helm's Deep, just when we had our backs to the wall, and those S. Aureus orcs just breaking through.
This doesn't absolve anybody from continuing with good handwashing technique though. It's a very good way of breaking the chain of infection that anyone can do.
