Characteristics of E. coli isolates with the blaIMP-4 gene from the silver gull on Five Islands. aIsolates with ≥85% similarity of PFGE profiles are assigned to the same cluster (designated as 1, 2, 3, etc.). Isolates from the same cluster with <100% identity of PFGE patters are indicated by letters (e.g. 5a, 5b, 6a, 6b, 6c, etc.). bFive of the six E. coli ST58 isolates (indicated by an asterisk) carry both blaIMP-4 and blaIMP-38. cIntegrons with intI1-blaIMP-4 arrays are missing the 3′ parts of the integron conserved region. dSTR, streptomycin; SUL, compound sulphonamides; TET, tetracycline; SXT, sulfamethoxazole/trimethoprim; CHL, chloramphenicol; GEN, gentamicin; NAL, nalidixic acid; CIP, ciprofloxacin; IPM, imipenem; MEM, meropenem. All isolates showed resistance to ampicillin, amoxicillin/clavulanic acid, cefalotin and ceftazidime. Resistance is indicated by ‘R’. Resistance patterns of isolates from the same cluster that show variable profiles are indicated by ‘X’. eTransfer of the gene by conjugation to recipient strains of E. coli. All isolates of E. coli ST58 carrying two blaIMP variants transferred only the gene blaIMP-4. fnt, plasmid non-typeable by PBRT.
