Haemophilus influenzae biotype VIII.

F O Sottnek, W L Albritton

    Journal of Clinical Microbiology
    |October 1, 1984
    PubMed
    Summary

    Six Haemophilus influenzae strains were unclassifiable by existing biotypes. These indole, urease, and ornithine decarboxylase-negative strains are proposed as a new biotype VIII.

    Area of Science:

    • Microbiology
    • Bacteriology

    Background:

    • Haemophilus influenzae is a significant human pathogen.
    • Biotyping is crucial for classifying H. influenzae strains.
    • Existing biotyping schemes (I-VII) do not encompass all strains.

    Purpose of the Study:

    • To characterize six unclassifiable Haemophilus influenzae strains.
    • To propose a new biotype for these strains.

    Main Methods:

    • Biochemical characterization of six H. influenzae strains.
    • Testing for indole, urease, and ornithine decarboxylase activity.

    Main Results:

    • Six strains were negative for indole, urease, and ornithine decarboxylase.
    • These results did not align with established biotypes I-VII.

    Conclusions:

    • The six strains represent a distinct group within H. influenzae.
    • A new biotype, designated biotype VIII, is proposed for these strains.
