Pathogen Profile

Carbapenem-resistant Acinetobacter

Acinetobacter spp. is a type of gram-negative bacteria that is a cause of pneumonia or bloodstream infections among critically ill patients. Fewer than 1 of 10 healthcare-associated infections are caused by Acinetobacter. However, many of these bacteria have become very resistant to antibiotics. Some strains are resistant to nearly all, or all antibiotics, including the carbapenems.

Geographic Locations

Antimicrobial resistance varies by location, driven by a number of factors, including antibiotic use and infection control practices in individual healthcare facilities, the underlying health and age of the patient population, and regional spread from nearby locations.

Changes Over Time in Carbapenem resistance Among Acinetobacter 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.

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.
