Enterobacter agglomerans: the clinically important plant pathogen

I W Geere

    Canadian Medical Association Journal
    |March 5, 1977
    PubMed
    Summary

    Enterobacter agglomerans, now Erwinia, was isolated from 13 hospital patients over 5 months. While often benign, this environmental bacterium shows potential for causing hospital-acquired infections.

    Area of Science:

    • Microbiology
    • Infectious Diseases
    • Hospital Epidemiology

    Background:

    • Enterobacter agglomerans, reclassified as Erwinia, is a common environmental bacterium.
    • Understanding its role in clinical settings is crucial for infection control.

    Purpose of the Study:

    • To investigate the occurrence and clinical significance of Erwinia (formerly Enterobacter agglomerans) in a general hospital.
    • To assess the potential for nosocomial infections caused by this organism.

    Main Methods:

    • Prospective isolation of bacteria from patients over a 5-month period.
    • Identification of isolates and assessment of their etiological role in patient infections.
    • Evaluation of antibiotic sensitivity patterns of the isolated strains.

    Main Results:

    • Erwinia was isolated from 13 patients, with one patient having isolates from two sites.
    • In six cases, Erwinia was the sole pathogen; in two, it may have contributed to infection.
    • The organism was likely a transient saprophyte in other instances.
    • Isolated strains exhibited biochemical variability but consistent colonial morphology and antibiotic sensitivity.

    Conclusions:

    • Erwinia, despite its environmental prevalence and generally benign nature, possesses the potential to cause nosocomial infections.
    • Clinical vigilance and further research are warranted regarding Erwinia's role in healthcare-associated infections.
