The urinary tract infections are among the most frequent pathologies in clinical consultations. The most common pathogenic mechanism of urinary tract infection is contamination by ascending urinary tract by microbial agents of intestinal microbiota. Urinary tract infection is the tissue invasion of any structure of the urinary tract, including the kidneys, ureters, bladder and urethra. The urinary tract can be filled with a wide variety of microorganisms, such as bacteria, fungi and viruses. The urinary tract infections more often called simple uncomplicated (cystitis), while infections that compromise the general condition, or are associated with other clinical factors are called complicated (pyelonephritis). Many clinical situations may be associated with urinary tract infection. The micro-organism is the most common invasive Escherichia coli detected in approximately 80% to 90% of bacterial infections uncomplicated acute urinary tract infection. Urinary tract infection can manifest clinically in various ways, depending on the sector committed urinary tract. The capacity of pathogenic enterobacteria Escherichia coli, is essential to who is the primary infectious agent in urinary tract infections. The presence of fimbriae, and other related structures, it is of great importance in virulence of the bacterium. Given this context, this work aims to conduct a bibliographic survey, on the essential characteristics of E. coli as the most significant causative agent of urinary tract infections; epidemiological aspects, the techniques used in laboratory diagnosis, treatment, prevention and clinical presentation of the disease.
