Hemophilus influenza septicemia and midtrimester abortion.

A case of midtrimester septic abortion due to Hemophilus influenza is discussed on the basis that the pathogeneses of the septic abortion was due to the hematogenous spread of the organism orginating from upper respiratory infection. The absence of ruptured membranes and the elevated antibody titer at the onset of the pelvic infection were in keeping with this hypothesis. Additional data on the bacteriology of this organism and the probability of the occurrence of a type b organism with original ampicillin resistance are presented.
