[Neonatal Haemophilus influenzae infection. Apropos of 4 cases].

Four cases of neonatal haemophilus influenzae have been reported in Intensive Care Unite of Timone's Hospital (Marseille) during a 2 year period. Three of the cases were due to non typable organism, one was a type III. Hemoculture was positive twice. None of the patients had meningitis. Clinically it was a neonatal septicemia without particularity. Prognosis is bad (50% mortality). Several hypothesis have been proposed to explain the increase of the frequency of this neonatal infection. One of the major problem is the choice and the moment of prescription of antibiotherapy.
