title: Haemophilus influenzae biotype VII.
abstract: A hitherto unreported biotype of Haemophilus influenzae is described. The isolate is noncapsulate and fails to decarboxylate ornithine or hydrolyze urea but is a strong indole producer. Its frequency is low. It is suggested that this newly recognized biotype of H. influenzae be designated biotype VII.
