Recently on the TV news (which is where I get most of my [mis]information), I've heard anthrax referred to sometimes as a bacteria and at other times as a virus. I've also been told by my doctor every winter that antibiotics are effective against one but not the other... but I forget which is which: are antibiotics prescribed for bacterial or viral infections? And which is anthrax?

Pardon my ignorance but, hey, I'm here to learn.
