Fig. 2From: The effect of short-course antibiotics on the resistance profile of colonizing gut bacteria in the ICU: a prospective cohort studyIncidence of antimicrobial resistance phenotype at ICU admission and 72 h later, based on culture for β-lactam resistance in Gram-negative bacteria, MRSA, and VRE. There was no significant increase in resistance after 72 h although there were trends in that direction. Chi-squared or Fisher’s p values are shownBack to article page
