Genes for antibiotic resistance?

gizmodo story for later reading

discusses how the bacteria evolve and even exchange genes to help survive antibiotics.

Then it notes:

New drugs are in development, such as teixobactin, which might delay the apocalypse, but are not yet ready for medical use.
Teixobactin, if you haven’t heard of it, is a new class of antibiotics discovered in soil bacteria earlier this year. When teixobactin was first published, it waslauded as a “game-changer” in the fight against antibiotic resistance. Here’s an excerpt from an article I wrote back in March explaining why:
It’s the first new class of antibiotics we’ve discovered in nearly thirty years, and so far, it’s killed every pathogen we’ve thrown at it, including several highly drug-resistant strains of staph. Unlike most antibiotics, which target critical bacterial proteins, this drug attacks the lipid molecules bacteria use to build new cell walls. Vanomycin, another antibiotic that targets cell wall precursors, worked for over 40 yearsbefore bugs started to develop resistance.
