RESUMO
Introduction: children with Occult bacterimia shows presenceof fever, difficulty in breathing, tachycardia, refusal of feeds,malaise or lethargy. In such a potentially life-threateningcondition, isolation of the causative pathogen in blood cultureis one of the most important bacteriological examinations withimportant clinical and therapeutic consequences.Material and methods: This prospective study was carriedout in the Central Teaching of Pediatric Hospital in Baghdad.Total 300 febrile patient aged from 1 days to 11 years of agewithout any localizing clinical features attending centralteaching hospital of pediatrics in Baghdad and who werenot hospitalized 30 days prior to the initial evaluation wereenrolled into the study.Results: Among 300 patients, 49 were positive for differentkinds of bacteria confirming OB and 235 were negative after18 hrs of incubation. Among different age groups, OB waspositive in 9.7% in age group 1day-<29 days, 4.3% in agegroup 1 month -<11 months, 1.0% in age group 1year-<5 yearsand age group 5years-10years represent (3/49) respectivelyand 0.3% in age groups over 11years.Conclusion: Occult bacteremia is the most prevalent conditionamong children’s less than one months. Imipenem, class ofquinolone antibiotic is found to be sensitive towards bacterialisolates and thus could be
