Antimicrobial Resistance Laboratory Network Data Explorer

Antimicrobial Resistance Laboratory Network Data Explorer is a new feature to AR&PSP that allows users to create custom visualizations using filters and drop-downs curated around the specific data sets available. Currently, the Antimicrobial Resistance Laboratory Network Data Explorer features AR Lab Network Data, but more data sets and visualization options will be added in future releases.

Footnotes

  • The AR Lab Network was not designed to be a traditional surveillance system. Isolates tested are a convenience sample and include clinical, surveillance, and outbreak specimens. Within each state, isolate submissions and testing are determined by state priorities and reporting regulations.
  • A map of the AR Lab Network regions is available at https://www.cdc.gov/antimicrobial-resistance-laboratory-networks/php/about/.
  • CP Isolates are defined as those testing positive for carbapenemase activity and/or any of the five targeted genes (KPC, NDM, VIM, IMP, OXA-48).
  • Carbapenem-resistant Enterobacterales (CRE) isolates were resistant to ertapenem, imipenem, meropenem, or doripenem using antimicrobial susceptibility testing breakpoints.
  • Carbapenem-resistant Pseudomonas aeruginosa (CRPA) isolates were resistant to imipenem, meropenem, or doripenem, using antimicrobial susceptibility testing breakpoints.
  • Carbapenem-resistant Acinetobacter baumannii (CRAB) isolates were resistant to imipenem, meropenem, or doripenem, using antimicrobial susceptibility testing breakpoints.
  • Carbapenemase gene screens aimed to detect colonization with bacteria carrying at least one of five targeted carbapenemase genes. Screens were positive when at least one of five targeted carbapenemase genes (KPC, NDM, VIM, IMP, OXA-48) was detected using real-time polymerase chain reaction (PCR).

  • Data displayed are updated as of June 2026. Given the structure of the AR Lab Network and its testing strategies, supplementary testing and the availability of improved methods and additional data may result in changes or corrections to data reported on PSP.
