Pneumococcal Bacteremia and Focal Infection in Young Children

Abstract

We reviewed a consecutive case series of 178 immunocompetent children aged 3-36 months without central venous lines who had blood cultures positive for Streptococcus pneumoniae by either of paired broth and quantitative culture methods. The incidence of accompanying focal infection was significantly greater in patients with >10 colony-forming units (cfu)/mL than in patients with <10 cfu/mL (30.4% vs 12.9% respectively, p=0.04). No significant relationships existed between the magnitude of bacteremia and the age, gender, presenting temperature, interval until the blood culture turned positive, total peripheral blood white cell count, absolute neutrophil count, or absolute band count. Overall, the quantitative method detected 59/178 (33.1%) of the isolates, including five isolates (2.8%) that the broth method failed to detect.
