Resistance Pattern of Gram-negative Bacilli from Tertiary Neonatal Intensive Care Units in Canada

We utilized antibiograms from 10 Canadian Neonatal Intensive Care Units to assess antimicrobial susceptibility patterns among Gram-negative bacilli during 2015-2021. Escherichia coli was the most prevalent isolate, with >85% susceptible to third-generation cephalosporin. The resistance to carbapenems was identified in <1% of the isolates.
