[Walking Dead] Can anyone survive a bite?

Everybody has the virus, and it activates when you die. Getting bitten just makes you sick as it's a decayed human mouth full of germs. If you had some really good antibiotics, could you survive a zombie bite?

Edit: This ignores how hard antibiotics are to come by in the post apocalyptic setting.

It didn't seem to help the early survivors who were able to receive good medical care in hospitals, including the CDC.  On the other hand, amputation works pretty well even though the survivor has an open stump in an unsanitary post-apocalyptic world.

So it appears that the bite has some agent that accelerates death once it circulates in the bloodstream.
