OBJECTIVE: To investigate whether translocation of intestinal Enterobacteriaceae was a likely source of bacteremia in children of 2 years or less hospitalized for fever and moderate malnutrition. METHODS: Blood and fecal cultures were obtained from 198 such children admitted in the Princess Basma Hospital (Irbid, Jordan). Enterobacteriaceae isolated from blood cultures were compared with those present in fecal cultures by genomic typing using pulsed-field gel electrophoresis. The characteristics of children whose blood and fecal strain typing patterns were not distinguishable, i.e. with documented translocation, were compared to those of children without documented translocation. RESULTS: Bacterial translocation was documented in 12 of 19 children (63%) with Enterobacteriaceae bacteremia for whom paired blood and fecal strains were available for genomic typing, and was thus the major source of these bacteremias. The clinical or biological signs of malnutrition were not significantly more pronounced in the bacteremic children with documented translocation than in those without. CONCLUSIONS: We demonstrated that bacterial translocation from the intestinal tract was the most common source of Gram-negative bacteremia in the population studied.
