Escherichia coli remains one of the most frequent causes of nosocomial and community-
acquired bacterial infections including urinary tract infections, enteric infections, and …

Since 2000, Escherichia coli producing CTX-M enzymes (especially CTX-M-15) have
emerged worldwide as important causes of community-onset urinary tract infections (UTIs) …

Enterobacteriaceae, especially Klebsiella spp. producing extended-spectrum β-lactamases
