    A 1974 survey found bronchiectasis in 1.6% of necropsied feedlot cattle. This lung disease involved permanently dilated bronchi filled with exudate and various bacteria, including Pasteurella species.

    Area of Science:

    • Veterinary Pathology
    • Bovine Respiratory Diseases

    Background:

    • Bronchiectasis is a chronic lung condition characterized by permanent dilation of bronchi.
    • Understanding the prevalence and causative agents of bronchiectasis in feedlot cattle is crucial for herd health management.

    Purpose of the Study:

    • To determine the prevalence of bronchiectasis in yearling feedlot cattle.
    • To identify microorganisms associated with bronchiectasis in affected cattle.

    Main Methods:

    • A survey of illnesses and deaths in approximately 407,000 yearling feedlot cattle throughout 1974.
    • Necropsy examination of 1,988 deceased cattle.

    Main Results:

    • Bronchiectasis was diagnosed in 32 (1.6%) of the 1,988 necropsied cattle.

  • Affected lungs showed permanently dilated small bronchi and bronchioles in ventral regions.
  • Accumulations of exudate and microorganisms, including Pasteurella hemolytica, Pasteurella multocida, Corynebacterium pyogenes, Escherichia coli, Salmonella anatum, Staphylococcus spp, and Mycoplasma arginini, were identified.

    • Conclusions:

    • Bronchiectasis occurred in 1.6% of necropsied feedlot cattle in 1974.
    • A diverse range of bacteria and Mycoplasma were implicated as causative or contributing agents in bovine bronchiectasis.
