[Neonatal Proteus mirabilis septicemia and cerebral abscess. Value of the assay of antibiotics in the puncture fluid].

The authors describe a case of neonatal Proteus mirabilis septicemia accompanied by cerebral abscess formation despite the presence of therapeutically effective antibiotic levels utilised to treat the disorder. The occurrence of such brain abscesses during the course of effective antibiotic therapy raises the question of the mechanism behind their formation. Cerebritis may occur very early in the clinical course of the infection without being due to failure of antimicrobial therapy.
