Antibiotics for gram-positive organisms

F S Pagan

    British Journal of Hospital Medicine
    |January 1, 1981
    PubMed
    Summary

    Most Gram-positive bacterial infections can be treated with a few key antibiotics like penicillin, cloxacillin, and erythromycin. Selective use of these narrow-spectrum drugs, guided by bacteriological investigation, minimizes harm to normal flora and side effects.

    Area of Science:

    • Microbiology
    • Infectious Diseases
    • Pharmacology

    Background:

    • Gram-positive organisms are common causes of infection.
    • A limited number of antibiotics can effectively treat most Gram-positive infections.

    Purpose of the Study:

    • To highlight the efficacy of narrow-spectrum antibiotics for Gram-positive infections.
    • To advocate for selective antibiotic prescribing practices.

    Main Methods:

    • Review of antibiotic spectrum and coverage for Gram-positive pathogens.
    • Analysis of treatment outcomes with selected narrow-spectrum agents.

    Main Results:

    • Penicillin, cloxacillin, and erythromycin cover approximately 90% of Gram-positive infections.
    • These antibiotics offer effective treatment with minimal disruption to normal bacterial flora.

    Conclusions:

    • Selective use of narrow-spectrum antibiotics like penicillin, cloxacillin, and erythromycin is recommended for Gram-positive infections.
    • Bacteriological investigation should guide the choice of antibiotics to ensure efficacy and minimize side effects.
