Klebsiella pneumoniae is a bacteria causing bloodstream infections, urinary and respiratory infections.
All EU Member States and two EEA countries (Island and Norway) reported data from invasive isolates, except for UK in 2020 and 2021. Roughly 76 percent of the participating countries had a high national representativeness, in terms of covered geographic areas, included acute care hospitals, and microorganisms causing infections.
*The aminoglycoside group includes only gentamicin and tobramycin from 2020 onwards.
**Combined resistance to fluoroquinolones, third-generation cephalosporins and aminoglycosides

Share of invasive resistant K. pneumoniae in EU/EEA 2017-2024, by antimicrobial group
Klebsiella pneumoniae is a bacteria causing bloodstream infections, and urinary and respiratory infections. As of 2024, resistance to third-generation cephalosporin antibiotics was the most common form of Klebsiella pneumoniae antibiotic resistance in EU and EEA countries, with **** percent, followed by resistance to fluoroquinolones.
