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.]]></p></abstract>

Las infecciones pediátricas causadas por R. ornithinolytica son sumamente raras, con solo seis casos publicados, de los cuales nada más dos se presentaron como infección de vías urinarias.  Caso clínico: Se describe una infección de vías urinarias polimicrobiana (R. ornithinolytica y Enterococcus faecalis) en un paciente pediátrico con leucemia linfoblástica aguda de células T, que fue tratado satisfactoriamente con ampicilina-sulbactam.  Conclusiones: Con base en lo que se sabe hasta el momento, se reporta el séptimo caso en un paciente pediátrico y el tercer caso de infección de vías urinarias causada por R. ornithinolytica en este grupo de edad.]]></p></abstract>
