Abstract

Objective: The purpose of this study was to compare maternal characteristics and neonatal morbidity and mortality rates that are associated with early-onset neonatal sepsis that is caused by group B Streptococcus and Escherichia coli. Study design: This was a retrospective review of newborn infants with a positive blood culture (and/or cerebrospinal fluid) that was positive for either E coli or group B Streptococcus during the first week of life. Data were abstracted from maternal and neonatal medical records. Results: Among 28,659 deliveries during the study period, 102 episodes of early-onset neonatal sepsis were identified, 61 of which were caused by group B Streptococcus and 41 of which were caused by E coli. E coli sepsis cases had a lower birth weight, a higher percentage with 5-minute Apgar score <7, and a longer stay in the hospital neonatal intensive care unit and required mechanical ventilation more frequently. Death after early-onset neonatal sepsis with E coli was also more frequent. Conclusion: Early-onset sepsis with E coli is associated with more morbidity and a higher mortality rate compared with early-onset group B Streptococcus.
