In the broadest sense of the word "bacteria", this could be true.  However, 
these days (and in fact for quite a while now), a separate branch of 
prokaryotic microbes is recognized: the archaea.  Archaea are distinct from 
true bacteria, and in many respects they are much more similar to us than 
they are to bacteria.

It all depends on whether or not you go for Woese's "Three Domain" 
hypothesis.  I do.
