Background: Currently, Raoultella ornithinolytica is considered an emerging pathogen of community- and hospital-acquired infection, particularly in patients with immunodeficiencies, malignancies, anatomical abnormalities, or after invasive procedures. Pediatric infections with R. ornithinolytica are exceedingly rare, with only six previously reported cases, of which only two were reported as a urinary tract infection. Case report: Here, we describe a polymicrobial urinary tract infection (R. ornithinolytica and Enterococcus faecalis) in a pediatric patient with T-cell precursor acute lymphoblastic leukemia, which was successfully treated with ampicillin-sulbactam. Conclusions: To the extent of our knowledge, we report the seventh case in a pediatric patient and only the third case of a urinary tract infection in this age group caused by R. ornithinolytica.
