Identification and characterisation of the location of blaCTX-M-14, blaSHV-2, blaSHV-12, blaCMY-2 and blaTEM among 11 cephalosporin resistant E. coli isolates.

p(ST number), plasmid location; Inc, identified replicon.a Isolates are divided in APEC (N) and AFEC (GN) strains.b Replicon identifications are based on positive amplifications from the PCR-based replicon typing method.c Plasmids were named based on the source strains sequence type and plasmid size.d In all E. coli isolates, replicons from plasmids containing the different bla genes were identified by PCR-positive amplification and by Southern hybridisation of the S1-digested fragments.Identification and characterisation of the location of blaCTX-M-14, blaSHV-2, blaSHV-12, blaCMY-2 and blaTEM among 11 cephalosporin resistant E. coli isolates.
