title: Bacterial meningitis: a new risk factor.
abstract: BACKGROUND
  The purpose of this study is to discuss a possible new risk factor for the bacterial meningitis.
  
  
  METHODS
  Cerebrospinal fluid collected from 270 patients was assayed. An enzyme immunosorbent assay for the detection of Staphylococcal enterotoxins A to E was used.
  
  
  RESULTS
  The results indicated that the frequency of Coagulase Negative Staphylococci (CoNS) was 35 (20.46%). An important finding of this research was that the CoNS isolates produced enterotoxin C and D or enterotoxin C and E.
  
  
  CONCLUSIONS
  This is the first report of enterotoxin-producing Coagulase Negative Staphylococci isolated from CSF patients. Therefore, these enterotoxins probably act as risk factors in the bacterial invasion into central nervous system.
