47 Decline in AmpC beta-lactamase-producing E. coli in a Dutch teaching hospital Figure S1. AFLP patterns from all AmpC producing E. coli eligible for cluster analyses (2013 & 2014) AFLP patterns from all AmpC producing E. coli eligible for cluster analyses. Strains clustering with a similarity between 90 and 100% were defined as identical strains. Strains clustering with a similarity above 35% were defined as different strains of the same species and strains clustering with a similarity below 35% were defined as different species. Identical strains are indicated in colour. Each strain was coded with type of resistance mechanism, the number of the year in combination with a letter. ATCC 35218 E.coli and DSM 4564 K.pneumoniae were used as reference strains. In 2014 a number of E.coli ESBL strains were selected for AFLP typing as well (further data on ESBL strains not shown is this publication). 3
