ESBL/AmpC-forming E. coli were detectable in the 38 poben. Carbapenemase-forming E. coli were not detectable in any of the samples. ESBL stands for "extended-spectrum beta-lactamase": these are enzymes that render the ß-lactam antibiotic ineffective. ESBL-producing bacteria are no more pathogenic than sensitive bacteria. This means they do not cause illness more often, but the treatment options (number of antibiotics available) are limited.
This focus action was a monitoring action, which is used to monitor and report antibiotic resistance according to EU requirements.
