Ampicillin bacteriocidal or static?

Hello,

I'm confused and hope someone here might be able to enlighten me. I just read in some 
medical microbiology book that penicillins and thereby Ampicillin are bacteriocides. 
This overthrows my whole view on things like the appearance of satellite colonies - 
how do they show up if not by releaved growth inhibition through Ampicillin by means 
of beta-lactamase secreted by Amp+ neighbours?

Thanks for any thoughts, Joh
