This study included children undergoing lumbar puncture in the emergency department. Bacteria were isolated from 34 (1.7%) of 1898 cerebrospinal fluid (CSF) enrichment broth cultures; 30 were contaminants. The primary CSF Gram stain was negative in all specimens with a positive enrichment broth culture. Enrichment broth cultures rarely contributed to the diagnosis of bacterial meningitis, and positive CSF enrichment broth cultures contributed to diagnostic uncertainty.
[Show abstract][Hide abstract] ABSTRACT: The records of cerebrospinal fluid (CSF) examinations for the three-year period ending 30 September 1991 were studied retrospectively. From 3,161 examinations, 66 pathogens were detected, 64 of which were from primary agar plate culture. Enrichment broth culture yielded 219 isolates of which 217 were likely contaminants. Only two pathogens were isolated by enrichment, and in both samples the CSF leucocyte counts were abnormal. The use of enrichment broth culture should be confined to CSF specimens with abnormal leucocyte counts and/or Gram stains.
