Pathogen Profile
Carbapenem-resistant Klebsiella
Klebsiella spp. cause pneumonia, urinary tract infections, and bloodstream infections in hospitalized patients, as well as in patients in nursing homes and other healthcare facilities. Carbapenem-Resistant Klebsiella spp. is a subset of the very resistant "nightmare" bacteria carbapenem-resistant Enterobacterales (CRE).

Changes Over Time in Carbapenem resistance Among Klebsiella spp.
This graph displays percent antimicrobial resistance from 2011 to 2024 for all event types. Blank areas of the chart represent 0% resistance, indicating that zero resistant pathogens were reported for the selected year, phenotype, and HAI type. “Insufficient data” indicates that less than 20 pathogens were isolated and tested for resistance.
Due to definition changes, caution should be used when reviewing this phenotype over time.

Footnotes
- HAIs include Catheter-associated Urinary Tract Infections (CAUTI), Central Line-associated Bloodstream Infections (CLABSI), and Surgical Site Infections (SSI).
- CI (Confidence Interval) - The national, regional, and state-level data included in Antimicrobial Resistance information are displayed with 95% confidence intervals around the percent resistance, which were calculated using a mid-P exact test and are an indication of precision.
- Map legends are classified using the Jenks Natural Breaks method.
- Klebsiella aerogenes is only counted in this phenotype for 2020 events and forward. Prior to 2020, this pathogen was referred to as Enterobacter aerogenes.
- The definition for this phenotype underwent changes in 2021. For more information, refer to the AR&PSP Phenotype Definitions.
