DF-2: a fastidious fermentative gram-negative rod.

S J Rubin

    European Journal of Clinical Microbiology
    |June 1, 1984
    PubMed
    Summary
    This summary is machine-generated.

    DF-2 bacteria, often linked to dog bites, can cause severe human infections, especially in those with underlying health issues or after spleen removal. Penicillin is the recommended treatment, as DF-2 shows resistance to aminoglycosides.

    Area of Science:

    • Microbiology
    • Infectious Diseases
    • Bacteriology

    Background:

    • DF-2 is a fastidious gram-negative rod causing human infections.
    • Infections are frequently associated with dog contact or bites.
    • Severe outcomes are linked to pre-existing conditions or splenectomy.

    Purpose of the Study:

    • To review current information on DF-2 human infections.
    • To outline methods for isolating and identifying DF-2.
    • To discuss antimicrobial susceptibility and treatment.

    Main Methods:

    • Literature review of 26 DF-2 infection cases.
    • Description of microbiological isolation and identification techniques.
    • Analysis of antimicrobial susceptibility data.

    Main Results:

    • DF-2 presents as long, thin, slow-growing, oxidase-positive, catalase-positive gram-negative rods.
    • The organism does not grow on MacConkey agar.
    • DF-2 exhibits resistance to aminoglycosides, with penicillin being the drug of choice.

    Conclusions:

    • DF-2 infections pose a significant risk, particularly in immunocompromised individuals.
    • Accurate identification relies on specific microbiological characteristics.
    • Effective management involves recognizing antimicrobial resistance patterns and selecting appropriate therapy.
