title: Meningitis in an adult caused by Hemophilus influenzae, biotype III.
abstract: An elderly woman had an abrupt onset of symptoms consistent with bacterial meningitis without an obvious source of infection. The organism, isolated from the blood and CSF, was a nonserotypeable Hemophilus influenzae, biotype III. To our knowledge, this is the first reported case of meningitis caused by this organism.
