Nontyphoidal Salmonella NTS can cause bacterial enterocolitis. Although some children with NTS infection develop bacteremia, its clinical manifestations have not been discussed adequately. Therefore, we examined children with NTS bacteremia. We retrospectively examined the medical records of 15 patients aged less than 15 years. Salmonella spp. were detected in the blood cultures of these patients between 1991 and 2014. We divided an additional sample group of 34 patients diagnosed with an NTS infection between 2005 and 2014, into 2 groups. Group bacteremia B included patients in whose blood cultures Salmonella spp. were detected, and group non-bacteremia NB included patients in whom Salmonella infection was not detected. We compared each group using Wilcoxon test and Fisher’s exact test. The number of patients with fever, diarrhea, or abdominal pain was 15 100%, 13 87%, and 9 60%, respectively, in the first sample of patients. However, vomiting and bloody stool were observed in only 5 patients 33%. More than 70% of patients exhibited a reduced white blood cell count, while C-reactive protein levels were variable in the patients. Salmonella spp. were detected via stool culture in 10 patients 67%. Diarrhea persisted for more than 4 days more frequently in group B than group NB p = 0.004. The number of patients whose fever persisted for more than 4 days was significantly higher in group B than group NB p = 0.030. Therefore, if NTS bacteremia is suspected, blood cultures should be collected and antibiotics should be initiated in cases with diarrhea or fever for more than 4 days. Furthermore, a negative stool culture result does not preclude the possibility of NTS bacteremia.
