Dear Doctor, types of ICU isolated microorganisms usually classified by 3 main factors;
1) Those, which acquired outside the ICU setting before transferred to ICU (above 50% ICU cases are pre colonized, a well-known fact), often termed as HAI (Hospital Acquired Infections) 2) Community acquired infections or CAI, also before transferring to ICU & 3) Via cross contamination between patients within the ICU by prevailing endogenous flora.
So its usually not limited to purely any ICU setup. Entire chain need to be looked out.
In my experience, I found CoNS, Acinetobacter, Enterococcus spp., E.coli and Candida mostly. I almost always got Acinetobacter baumannii from Ventilated ICU patients.
In an ICU setting, we need to know that the incidence rate of UTI is the highest one (mainly catheter related), then VAP and then the BSI (blood-stream). So the infection source also matters a lot in terms of finding the causative agent in ICU.
Dear Manar, this article will help you:

Epidemiology, prevalence, and sites of infections in intensive care units.

It really depends on where you are, and the infection prevention practices. We see quite a few K. pneumoniae in our ICU patients on top of the common ones mentioned above.
