Antimicrobial resistance in Pseudomonas aeruginosa (P. aeruginosa)

Last updated on Thursday, 10 July 2025 at 10:58am

This page provides information on resistance to antimicrobials in Pseudomonas aeruginosa bacteraemia (bacteria found in blood specimens). Data breakdowns are available for England and by UKHSA Region.

Overview

Antibiotics are grouped based on the UK-AWaRe classification. These are:

Access
Access antibiotics are with a narrow spectrum of activity, fewer side effects, lower costs, and importantly lower resistance potential. These are first or second choice antibiotics recommended for empiric treatment of the most common infections and should be widely available. That is to say, these antibiotics should offer the best therapeutic value while minimizing the potential for resistance.

Watch
Watch antibiotics have a higher resistance potential and are broader-spectrum antibiotics. These are first or second choice antibiotics indicated for a limited number of infective syndromes. As these antibiotics are considered to have a higher potential for selection of AMR, their use should be carefully monitored.

Reserve
Reserve antibiotics are “last resort” antibiotics, including new antibiotics. These are used for highly selected patients (life-threatening infections due to multi-drug-resistant bacteria) and are closely monitored and prioritized as targets of stewardship programmes to ensure continued effectiveness.

Resistance

Rolling monthly average percent of P. aeruginosa bacteraemia resistant to amikacin, carbapenems, ceftazidime, ciprofloxacin, gentamicin and piperacillin with tazobactam. Monthly figures are shown as the first day of each month. For example, the figures for January 2022 are shown as at "1 Jan 2022".

Up to and including month of 1 Mar 2025

Note 1: The chart shows a three-month rolling average, so the data shown for one month is the average across that month and the previous two months. Note 2: Interpreting national antibiotic resistance surveillance trends spanning European Committee on Antimicrobial Susceptibility Testing (EUCAST) clinical breakpoint transition periods requires additional consideration to avoid misinterpretation of data.
