Project

Preparatory work in the analysis and reporting of data on multi-resistance in antimicrobial resistance isolate based data collected from reporting countries for the year 2012 (R-4702)

The European Food Safety Authority (EFSA) is charged with coordinating the annual reporting of zoonoses, zoonotic agents, antimicrobial resistance (AMR) and food-borne outbreaks in the European Union under the Directive 2003/99/EC as well as analysing and summarising the data collected. Until the year 2010, data on antimicrobial resistance (AMR) in animals and food were submitted by the reporting countries and analysed by EFSA on an aggregated level (i.e. as numbers of isolates resistant to a given antimicrobial substance out of the total number of isolates tested). However, data at bacterial isolate level enable more in-depth analysis of resistance, including multi-resistance patterns of isolates and description of clonal spreading of resistant strains. A pilot project for the collection of isolate based AMR data from volunteering reporting countries was carried out in 2010. In 2011, a more elaborate study was carried out, in which data was collected from 13 Member States. For the year 2012, data was collected from 15 Member States. This report focuses on the analysis of multi-resistance, co-resistance and complete susceptibility patterns in these isolate-based AMR data, containing information on Salmonella, Campylobacter, indicator E. coli and indicator enterococci isolates from food and animal samples for the year 2012. In addition, several methods to identify possible clusters of similar multi-resistance patterns are described and exemplified based on selected subsets. Finally, interest is also in the identification of a possible time trend regarding the resistance to certain antimicrobials. Results are shown through specific summary tables as well as graphical representations.
