Klebsiella urinary tract infection

A Klebsiella urinary tract infection is an infection of the urinary tract, including the bladder (cystitis) or kidneys (pyelonephritis), caused by Gram-negative bacilli of the genus *Klebsiella*, most commonly *Klebsiella pneumoniae* While it can present as an uncomplicated community-acquired infection, it disproportionately affects hospitalized patients, older adults, individuals with structural urinary tract abnormalities, and those with indwelling urinary catheters

Pathophysiologically, the organism ascends the urethra into the urinary system, utilizing virulence factors such as polysaccharide capsules, fimbriae, and biofilm formation to colonize uroepithelial tissues and medical devices
