Escherichia vulneris: isolation and treatment.

K R Dye, L Dall, J Yuhas

    Southern Medical Journal
    |December 1, 1984
    PubMed
    Summary

    Two cases of Escherichia vulneris wound infections showed resistance to oral ampicillin. However, these infections responded to parenterally administered ampicillin, achieving higher blood levels.

    Area of Science:

    • Microbiology
    • Infectious Diseases
    • Clinical Medicine

    Background:

    • Escherichia vulneris is an emerging pathogen.
    • Antibiotic resistance is a growing concern in wound infections.
    • Ampicillin is a commonly used antibiotic for bacterial infections.

    Observation:

    • Two patients presented with wound infections caused by Escherichia vulneris.
    • These infections were resistant to orally administered ampicillin.
    • Microbial cultures confirmed the presence of Escherichia vulneris.

    Findings:

    • The Escherichia vulneris isolates demonstrated resistance to ampicillin when given orally.
    • Higher blood concentrations of ampicillin, achieved through parenteral administration, were effective against the infections.
    • This suggests a dose-dependent or route-dependent efficacy of ampicillin against this specific pathogen.

    Implications:

    • Parenteral ampicillin may be a viable treatment option for severe or resistant Escherichia vulneris wound infections.
    • This highlights the importance of considering administration routes and achievable drug levels in treating infections.
    • Further research is needed to understand the mechanisms of ampicillin resistance in Escherichia vulneris and optimize treatment strategies.
