Abstract
96 patients with meningitis due to Neisseria meningitidis and Diplococcus pneumoniae were treated with epicillin or ampicillin according to a predesigned randomization chart. Results indicate that epicillin and ampicillin are effective single drugs in the treatment of meningococcal and pneumococcal meningitis. No adverse reactions were noted with either drug and they were comparable in their efficacy.
