S L Eustis, M E Bergeland

    Journal of the American Veterinary Medical Association
    |April 1, 1981

    Summary

    Braxy, a rare gastrointestinal disease, was diagnosed in a calf and lambs in South Dakota. This finding expands the known host range and geographic distribution of this serious animal infection.

    Area of Science:

    • Veterinary Pathology
    • Microbiology
    • Animal Science

    Background:

    • Braxy is an acute, often fatal, gastrointestinal disease primarily affecting sheep.
    • It is caused by Clostridium septicum, a bacterium that proliferates in the abomasum.
    • The condition is characterized by severe inflammation, edema, and emphysema of the abomasal wall.

    Purpose of the Study:

    • To report a rare case of braxy in young livestock in the United States.
    • To identify the causative agent and characterize the pathological findings.
    • To assess the potential for braxy to affect species other than sheep.

    Main Methods:

    • Necropsy and histopathological examination of affected animals.
    • Identification of Clostridium septicum using direct immunofluorescence.
    • Bacteriological isolation and identification of Clostridium septicum from abomasal tissues.

    Main Results:

    • Severe, diffuse suppurative inflammation, edema, and emphysema were observed in the abomasal walls of a calf and two lambs.
    • Clostridium septicum was identified in the abomasal wall of all affected animals.
    • The clinical and pathological findings were consistent with braxy.

    Conclusions:

    • This study confirms braxy in a young calf and lambs, expanding the known host range beyond sheep in the United States.
    • The findings highlight the importance of considering braxy in cases of severe abomasitis in ruminants.
    • Further investigation into the epidemiology and risk factors for braxy in diverse livestock populations is warranted.
