Neonatal septicemia caused by pneumococci

Pneumococci (Streptococcus pneumoniae) infrequently cause neonatal septicemia. An increased number of cases have been reported in recent years, but no increase in the relative incidence among neonatal infections has been noted. On the basis of two cases of our own and a review of 40 recently published case reports, the clinical characteristics of pneumococcal septicemia are described and the pathogenesis is discussed. The presenting clinical picture in early‐onset pneumococcal septicemia is dominated by respiratory distress, frequently accompanied by leukopenia, and is indistinguishable from that seen in septicemia caused by Group B Streptococci (GBS). The onset is preceded by prelabor rupture of the fetal membranes in almost half of the instances. The mortality is 50%, twice the figure given in recent GBS reports.
