Their proteins may be different, but it's quite likely that they use
several of the basic amino-acids that construct our proteins. Alien
bacteria may not care how our proteins in total look like, they will "chew"
on us and break the proteins down to basic amino-acids.
As long as we or our body can't kill the alien bacteria effectively, we are
out of luck.
