Table 3 Rectal colonization with resistant Gram-negative bacteria at ICU discharge and at different time points after ICU discharge and number of resistance phenotypes (to ceftazidime, tobramycin, colistin, meropenem and ciprofloxacin)

From: Carriage of antibiotic-resistant Gram-negative bacteria after discontinuation of selective decontamination of the digestive tract (SDD) or selective oropharyngeal decontamination (SOD)
