How did I get a bacteria called Enterobacter cloacae in my breast lift with implants?

lift with implants 1/19/17, when stitches were takin out my right breast became very [RS bleep] and smelt weird went to dr and I had a open wound that was leaking.he packed it and swabbed to test for bacteria put me on cipro (21day supply) he packed for a week and the I went back under the knife for closure of the wounds, test came back it was Enterobacter cloacae, did I most likely get that while in surgery? should I be concerned that bacteria could return?
