Raoultella ornithinolytica urinary tract infection in a pediatric patient with t-cell precursor acute lymphoblastic leukemia

Abstract

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 procedu-res. 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. ornithi-nolytica 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.
