A urinary tract infection (UTI) is an infection in any part of urinary system, which can happen anywhere includes kidneys, ureters, bladder and urethra. Most infections involve the lower urinary tract which include bladder and the urethra [1]. It occurs when any of the above mentioned part of urinary tract become infected with pathogen most frequently gram negative bacteria Escherichia coli (E. coli) which is considered the most prominent pathogen however, other bacteria my infrequently be present [1]. Different studies showed no variation in urinary tract uropathogens where E. coli revealed the highest predominate although, other causative pathogens were involved over the years [2,3]. Infections typically occur when bacteria enter the urinary tract through the urethra and begin to multiply in the bladder and collapsed defense mechanism that designed to keep out such microscopic invaders out of urinary tract and allow these invaders to take hold and multiply causing a full-blown infection in the urinary tract causing different of kind of illness from simple to severe if they reach the kidney and death if reach blood stream (sepsis).
