Entry title:

Antimicrobial resistance in Escherichia coli (E. coli)

Last updated on Thursday, 29 May 2025 at 04:00pm

This page provides information on resistance to antimicrobials in Escherichia coli bacteraemia (bacteria found in blood specimens). Data breakdowns are available for England, by UKHSA Region and by Integrated Care Board.

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 E. coli bacteraemia resistant to co-amoxiclav, ciprofloxacin, gentamicin, piperacillin with tazobactam, amikacin, carbapenems or third-generation cephalosporins. 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 Feb 2025

About

Source: AMR module of Second Generation Surveillance System (SGSS). SGSS is a live reporting database, and therefore data is subject to change. 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.

Amikacin

Testing

Rolling monthly average number of E. coli bacteraemia tested for resistance to amikacin. 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 Feb 2025

ChartThere is only 1 plot on this chart. The horizontal X-axis is labelled 'date'. Whilst the vertical Y-axis is labelled 'metric'. This is a dark blue solid bar plot. This plot shows data for E-coli. Specifically the metric 'e-coli_testing_bacteraemiaNumberTestedRollingMonth' for the England area, along with the age banding of 'all' for the gender group of all. This plot shows data from 01 April 2020 to 01 February 2025. It fell from 1703.0 on 01 April 2020 to 1663.67 on 01 January 2021. It rose from 1634.0 on 01 February 2021 to 1900.33 on 01 November 2021. It rose from 1853.67 on 01 December 2021 to 2106.33 on 01 September 2022. It rose from 2078.0 on 01 October 2022 to 2203.33 on 01 July 2023. It fell from 2256.0 on 01 August 2023 to 2203.33 on 01 May 2024. And finally. It fell from 2236.0 on 01 June 2024 to 1987.67 on 01 February 2025. There is no reporting delay period being tracked for the data on this chart. - Refer to tabular data.

Source: AMR module of Second Generation Surveillance System (SGSS). SGSS is a live reporting database, and therefore data is subject to change. 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.

Ciprofloxacin

Testing

Rolling monthly average number of E. coli bacteraemia tested for resistance to ciprofloxacin. 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 Feb 2025

ChartThere is only 1 plot on this chart. The horizontal X-axis is labelled 'date'. Whilst the vertical Y-axis is labelled 'metric'. This is a dark blue solid bar plot. This plot shows data for E-coli. Specifically the metric 'e-coli_testing_bacteraemiaNumberTestedRollingMonth' for the England area, along with the age banding of 'all' for the gender group of all.

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.

Resistance

Rolling monthly average percent of E. coli bacteraemia resistant to co-amoxiclav. 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 Feb 2025

About

Source: AMR module of Second Generation Surveillance System (SGSS). SGSS is a live reporting database, and therefore data is subject to change. 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.
