E. coli genitourinary tract infection

An *Escherichia coli* genitourinary tract infection is an infectious disease of the urinary system and associated reproductive structures caused by pathogenic strains of the gram-negative bacillus *E. coli*, most commonly uropathogenic *E. coli* (UPEC) The condition arises when bacteria originating from gastrointestinal flora ascend into the urethra, bladder, kidneys, or adjacent genital tissues such as the prostate Depending on the specific anatomical site involved, patients typically present w...

An *Escherichia coli* genitourinary tract infection is an infectious disease of the urinary system and associated reproductive structures caused by pathogenic strains of the gram-negative bacillus *E. coli*, most commonly uropathogenic *E. coli* (UPEC) The condition arises when bacteria originating from gastrointestinal flora ascend into the urethra, bladder, kidneys, or adjacent genital tissues such as the prostate

The condition arises when bacteria originating from gastrointestinal flora ascend into the urethra, bladder, kidneys, or adjacent genital tissues such as the prostate Depending on the specific anatomical site involved, patients typically present with localized irritative symptoms—such as dysuria, urinary frequency, urgency, and pelvic or flank pain—or systemic manifestations including fever, chills, and malaise

Virulence factors like adhesins and fimbriae allow the organism to attach to and invade urothelial surfaces, evading local host defenses and inducing acute inflammation
