Urinary tract infection is among the most common nosocomial and community acquired infections. The Information on prevailing levels of antimicrobial resistance among common pathogens that associated with urinary tract infection is useful in making an appropriate choice of empiric therapy .Resistance to antibiotic treatment in patients with urinary tract infections (UTIs) is a representative example of the increasing problem of antimicrobial resistance. Extended-spectrum β-lactamases (ESBLs) has emerged as an important mechanism of resistance in Gram-negative bacteria.

Urinary tract infection is among the most common nosocomial and community acquired infections. The Information on prevailing levels of antimicrobial resistance among common pathogens that associated with urinary tract infection is useful in making an appropriate choice of empiric therapy .

Resistance to antibiotic treatment in patients with urinary tract infections (UTIs) is a representative example of the increasing problem of antimicrobial resistance. Extended-spectrum β-lactamases (ESBLs) has emerged as an important mechanism of resistance in Gram-negative bacteria.

Bacterial production of extended-spectrum β-lactamases (ESBL) significantly reduces the efficacy of the most commonly used beta-lactam antibiotics for the empiric therapy of infections caused by putative Gram-negative .

Extended Spectrum Beta-Lactamase (ESBL) is derived from the mutated beta-lactamase enzyme, Beta-lactamase is an enzyme produced by bacteria that acts to inactivate beta-lactam class of antibiotics .

Extended Spectrum Beta-Lactamase is most commonly produced by the Enterobacteriaceae group, especially Escherichia coli and Klebsiella pneumonia.

ESBL-producing bacteria can also be resistant to the antibiotics class of aminoglycoside, fluoroquinolone, tetracycline, chloramphenicol, and sulfamethoxazole-trimethoprim.

The presence of ESBL-producing bacteria in an infection can result in treatment failure. Antibiotic resistance causes a decrease in the effectiveness of treatment, increases transmission of infection, increases mortality, and increases the cost of health care, while the discovery of new antibiotics is getting less and less
