Neonatal meningitis in Nigerian infants.

53 Nigerian infants with neonatal meningitis were prospectively studied. The striking features were: (a) the higher predisposition (26.7-fold) of LBW infants to developing meningitis than has been previously reported in the literature; (b) the predominant role of E. coli and Staphylococcus aureus; and (c) the rarity of salmonella organisms and the conspicuous absence of group B streptococcus as aetiological pathogens. The outcome was related to the age of onset and type of micro-organism. The presence of neurological signs, particularly nuchal rigidity and bulging anterior fontanelle, carried a poor prognosis. The overall mortality was 37.7%.
