European Antimicrobial Resistance Surveillance Network (EARS-Net)

Last modified at 4/21/2016 9:25 PM by Vladimir Prikazsky

EARS-Net (European Antimicrobial Resistance Surveillance Network) is a European network of national surveillance systems that maintains a comprehensive surveillance and information system with European reference data on antimicrobial resistance for public health purposes.

Antimicrobial resistance in Europe is monitored by a network of national surveillance systems in the European countries. The national networks systematically collect data from clinical laboratories in their own countries and upload the data to a central database maintained at ECDC (The European Surveillance System - TESSy). After uploading, each country approves its own data and the results are made available from the ECDC website.  

In order to maintain and facilitate the data reporting, ECDC ensures: 

  • validation of data from antimicrobial susceptibility tests of seven important bacteria pathogens isolated from patients with invasive infections;
  • analysis of trends in the occurrence of antimicrobial resistance over time and between different countries and regions;
  • EQA and protocols on testing methods to improve the consistency and quality of the data.

EARS-Net performs surveillance of antimicrobial susceptibility of seven bacterial pathogens commonly causing infections in humans: 

  • Streptococcus pneumoniae 
  • Staphylococcus aureus 
  • Enterococcus faecalis   
  • Enterococcus faecium   
  • Escherichia coli 
  • Klebsiella pneumonia 
  • Pseudomonas auruginosa
