We describe the genetic background of blaTEM-4 and the complete sequence of pRYC11::blaTEM-4, a mosaic plasmid highly similar to pKpQIL-like variants, predominant among TEM-4 producers in a Spanish hospital (1990-2004) which belong to Klebsiella pneumoniae and Escherichia coli high-risk clones responsible for the current spread of different antibiotic resistance genes. Predominant populations of plasmids and host adapted clonal lineages seem to have greatly contributed to the spread of resistance to extended-spectrum cephalosporins
