Letters.indd LETTERS ESBL-producing isolates of human and animal origins (10); no clonality was observed for the other 7 isolates by pulsed-fi eld gel electrophoresis, E. coli ST131 has emerged as a worldwide pathogen and causes mainly community-onset extraintestinal infections. Although the pandemic spread of E. coli ST131 was fi rst identifi ed in isolates producing CTX-M-15 ESBL, it is increasingly recognized that isolates belonging to this clone may also harbor other drug resistance determinants. Among acquired AmpC β-lactamases, CMY-2 has been most frequently reported in ST131 from human clinical isolates (3). Infections caused by CMY- producing E. coli are common but underrecognized because of the lack of standardized detection methods (2). Given the rapid global spread of the ST131 clone and the possibility of its transmission from food animals to humans, coupled with an abundance of CMY-2–encoding plasmids in poultry environments, E. coli ST131 producing CMY-2 β-lactamase may have potential to spread to humans. Our results also show that E. coli producing CMY-2 continues to be found commonly among retail chicken products in our study area.
