Sir, Escherichia coli clonal group ST131 has been reported from many parts of the world and is frequently associated with production of CTX-M-type extended-spectrum β-lactamase (ESBL), in particular CTX-M-15.1,2 Clonal group ST131 may be associated with other β-lactamases or may be resistant to fluoroquinolones; some isolates may be cephalosporin susceptible.3 Thus far, there are no reports of the clonal group ST131 E. coli in Australia. In this study, 49 E. coli clinical isolates resistant to cephalosporins and/or fluoroquinolones collected from six clinical microbiology laboratories in south-east Queensland between 2008 and 2009 were investigated for the presence of this clonal group.
