CTX-M enzymes: origin and diffusion [PDF]
Frontiers in Microbiology, 2012 CTX-M β-lactamases are considered a paradigm in the evolution of a resistance mechanism. Incorporation of different chromosomal blaCTX-M related genes from different species of Kluyvera has derived in different CTX-M clusters.
