(Results) p LJ1, a transferable plasmid that was present in 86 % of the extended-spectrum b-lactamase producing collection, was found to harbour an integron carrying aad B, a gene cassette for gentamicin, kanamycin and tobramycin resistance and a bla SHV-12 gene for third generation cephalosporin resistance.(Justification of results) The presence of this plasmid accounts for the gentamicin resistance phenotype that is often associated with organisms displaying an extended-spectrum b-lactamase phenotype.(Jones 2004, p.9)Abstract(Background statement) A review of groundwater remediation in use today shows that new techniques are required that solve the problems of pump and treat, containment and in-situ treatment.You can also see that there are differences in the type of information that is included in each abstract, as well as differences in level of detail.Abstract(Background statement) The spread of antibiotic resistance is aided by mobile elements such as transposons and conjugative plasmids.
