Abstract
We describe an infant with meningitis and septicemia due to infection with two different strains of Haemophilus infitenzae, with a urinary tract infection due to Escherichia coli and in whom herpes virus encephalitis was diagnosed within three days. Acinetobacter cal‐coaceticus septicemia developed three weeks later. No immunological deficiency could be demonstrated in the patient who recovered finally, albeit with sequelae due to encephalitis.
