Sir,

In recent years, the dissemination of Escherichia coli strains harbouring extended-spectrum ß-lactamases (ESBLs) in clinical settings has caused a great deal of concern. Most ESBLs are derived from the classical TEM-1, TEM-2 and SHV-1 enzymes by amino acid substitutions in their sequences.1 A new type of ESBL, CTX-M enzymes, is increasingly being reported among human clinical E. . . .
