Klebsiella oxytoca is a gram-negative bacterium found in fecal microbiota and known to cause several infections in humans, including antibiotic-associated hemorrhagic colitis. We present here a case of colitis caused by K. oxytoca toxin-producing strains that evolved in chronic diarrhea successfully treated by fecal microbiota transplant.
Keywords: Klebsiella oxytoca; antibiotic-associated hemorrhagic colitis; fecal microbiota transplant; toxin.
