Diagnosis of extraintestinal pathogenic pathogenesis in urinary tract infection.

Extra-intestinal pathogenic (ExPEC) is a virulent pathogen found in humans that causes the majority of urinary tract infections, and other infections such as meningitis and sepsis. ExPEC can enter the urinary tract through two modes: ascending from the bladder or descending from the kidneys. Human anatomical structures generally prevent the transmission of pathogens between the extra-intestinal area, kidneys, bladder, and urinary tract.
