Neonatal sepsis at The Johns Hopkins Hospital, 1969-1975: bacterial isolates and clinical correlates.
The experience with neonatal sepsis at The Johns Hopkins Hospital during 1969-1975 was reviewed. Major pathogens included Escherichia coli, group B streptococcus, other streptococci, and Klebsiella. Nineteen percent of coliform isolates were kanamycin-resistant. The frequency of recovery of E. coli was increased in early-onset sepsis, and the frequency of recovery of Klebsiella was increased in late-onset sepsis. The mortality rate was 23%. The frequency of recovery of E. coli was increased in fatal cases, and mortality was highly correlated with the presence of gastrointestinal catastrophe. Ampicillin and gentamicin are the initial antibiotics of choice for neonatal sepsis at this institution; a penicillinase-resistant penicillin should be added when Staphylococcus aureus involvement is likely, and addition of chloramphenicol or clindamycin should be considered for infants at increased risk for Bacteroides fragilis sepsis.
