Bacterial resistance to antibiotics is a major public health problem. The epidemiology of enteric bacteria including E. coli is changing rapidly with the global spread of a resistance mechanism type beta-lactamase extended spectrum (ESBL), responsible for resistance to almost all penicillins and cephalosporins. The resistance is up to 75% for Quinolones, 67% for Cotrimoxazole and 30-50% for Aminoglycosides.
