The role of escherichia coli in urinary tract infections

Despite being considered sterile, urine is one of the biological fluids that suffer the most contamination. Urinary tract infection is a pathology that affects most people, regardless of age or sex. When there is a decrease in the immunological state and an invasion of an aggressive agent by bacteria or fungi, the individual's physiological state is compromised and an inflammation. The present work aims to evaluate the etiological aspects of Escherichia coli, addressing its role in urinary tract infections, knowing the virulence factors, outlining the pathophysiological mechanisms and highlighting its incidence in different populations. The methodology of this article consists of a literature review, with bibliographic and descriptive research, through reading scientific articles aimed at urinary tract infection.Thus, an effective diagnosis is of great importance, based on clinical signs and symptoms and laboratory findings, where there is the identification of the causative agent of the infection, which will trace knowledge about uro-pathogens. According to results, Escherichia coli is mainly responsible for urinary tract infections.
