Fatal early-onset neonatal sepsis due to Streptococcus pneumoniae.
Two cases of invasive early-onset neonatal pneumococcal sepsis are reported. One neonate was born at term with no risk factors and the other preterm at 35 weeks. Sepsis was not detected at birth for either of these babies and diagnosis was made at the stage of severe sepsis. A fatal outcome resulted despite treatment. Pneumococcal sepsis was confirmed after death in both these cases. Although maternal carriage was not documented in either case, the ages at presentation and progression suggested perinatal acquisition of infection. Early onset neonatal pneumococcal sepsis presents similarly as early onset neonatal Group B streptococcal (GBS) sepsis. Vaginal carriage of pneumococcus is rare but the micro-organism may have a higher invasion to colonisation ratio (attack rate) than GBS. Risk factors for invasive disease are similar to GBS.
