Do i have to sanitize my syphon when moving beer from the secondary to the keg? Does the co2 keep bacteria and infection at bay?

You must sanitize ANYTHING that your beer will touch. Siphon, tubing, keg, probably should even spray down the neck of your carboy after you take the airlock and stopper out. Remember, you can't over sanitize but you can definitely under sanitize. I usually sanitize everything. Even my clamp that goes in the outside of my tubing. Not because it needs it but because its easier just to throw everything in the StarSan at the beginning and not worry about it later.

Sort of. There's a few things at work, though.

Alcohol beverages, beer in this case, are inherently inhospitable to bacterial infections. Not much, and certainly nothing that is known to be deadly or seriously harmful, can harbor itself in beer. That's obviously POST fermentation.

During the fermentation process, wort has a tendency to create a lot of yeast that in turn create a lot of CO2. This off-gassing does create a sort of "natural barrier" that protects the beer, but it doesn't mean you can be reckless with the beer. You can find examples of open fermenters in use at commercial breweries, but it does have risks. The concept of using wild yeast and souring, to most extents, is built around trying to replicate nature in a more perfect way.

What you're aiming for, though, is a fully sanitized environment from the time it cools in your boil kettle all the way to bottling/kegging. Everything that touches it should be thoroughly sanitized and a spray bottle/Vinator of Starsan are wonderful things. Oh, and don't blow a bunch of unknowns into your beer with a fan.

Have fun!
