BACKGROUND: Fever in infants younger than 90 days may reflect a serious bacterial infection, so blood cultures (BC) are taken routinely and the patient is hospitalized. The observation time to detect occult bacteremia is not well established. AIM: To describe type and positivity time of isolated bacteria in blood cultures in infants under 90 days admitted for fever. METHODS: Retrospective, descriptive study. Positive blood cultures taken between 2014-2016 in young infants admitted for fever were included. Identification and time of positivity of each bacteria, clinical, laboratory and demographic data were recorded. Demographic variables and the clinical outcome was obtained. RESULTS: There were 172 positive blood cultures, only 51 met inclusion criteria. Of these, 21 microorganisms were pathogenic (Escherichia coli: 10, Streptococcus agalactiae: 3, Streptococcus pyogenes: 3, others: 5) and 30 were considered contamination, mainly coagulase negative Staphylococcus. In relation to the total sample, the median time of positivity was 10 hrs. At 24 hours of culture, bacterial growth was detected in 94% of the sample. CONCLUSION: The pathogenic bacteria isolated in the blood cultures of patients younger than 90 days who were admitted with fever correspond mainly to Gram negative bacilli and streptococci. All isolated pathogens were detected before 24 h of incubation.
