PTs on molecular typing of pathogenic E. coli strains - ISS (EN)
European Union Reference Laboratory for Escherichia coli
Proficiency tests on detection, identification and typing methods for STEC
Proficiency tests on detection, identification and typing methods organized by the EURL-VTEC, are conducted for the NRLs for E. coli. The participation of reference laboratories from third countries is also welcome but these laboratories shall support the expenses for the sample shipment on their own budgets. The anonymized overall results of all the studies are available in the final reports published below. Participants also receive an individual reports from the EURL-VTEC within one week from the closure of the online platform used to contribute the results.
The EU DG SANTE will have access granted to the non-aggregated results of the single EU NRLs.
In this section, the procedure used by the EURL-VTEC to evaluate the NRL performance in the EQA is also available.
The PT scheme on molecular typing of pathogenic E. coli strains aims at evaluating and improving the capacity of the NRLs to perform molecular typing of the isolates, to best accomplish the duty of contributing to the upcoming European database of molecular typing data managed by the European Food Safety Authority (EFSA). From 2018, these PT schemes include methods based on NGS and from 2019 The PT schemes on molecular typing are only based on NGS. All the reports are available for download.
