Maternal and neonatal sepsis caused by Haemophilus influenzae type d

A 29-year-old pregnant woman was admitted to hospital with signs of sepsis and threatened preterm labour. The premature neonate also showed signs of sepsis. Haemophilus influenzae biotype III was cultured from a midstream urine sample taken from the mother, maternal placental swabs and neonatal blood cultures. The placental and neonatal isolates were both found to be serotype d by PCR, and were indistinguishable by PFGE.
