Flavobacterium meningosepticum in the neonatal period.

We have described a term newborn infant who developed Flavobacterium meningosepticum meningitis at 9 days of age. The case demonstrates the tenacity and changing antibiotic sensitivity of this organism. We used trimethoprim-sulfamethoxazole (Bactrim) intravenously to obtain CSF sterilization. On follow-up this child was neurologically intact.
