Summary
This summary is machine-generated.

Ultrasonography effectively detects bovine enzootic hematuria (BEH) even in pre-clinical stages. This imaging technique identifies bladder lesions in cattle, aiding early diagnosis of BEH before clinical signs appear.

Area of Science:

  • Veterinary Medicine
  • Diagnostic Imaging
  • Ruminant Health

Background:

  • Bovine enzootic hematuria (BEH) is a significant health concern in cattle.
  • Ultrasonography (US) has diagnostic potential for BEH but is underutilized in ruminant clinics.
  • Limited studies compare US findings across healthy, subclinical, and clinical BEH stages.

Purpose of the Study:

  • To describe ultrasonographic findings in cattle at various stages of BEH.
  • To evaluate the diagnostic capacity and precocity of ultrasonography for BEH detection.
  • To identify US markers for early and pre-clinical BEH diagnosis.

Main Methods:

  • Study involved 46 dairy cattle (females >18 months) across five Brazilian farms.
  • Animals were classified as clinical BEH (CH), subclinical BEH (SCH), or healthy (HA) based on history, clinical exam, and urinalysis.

  • Bladder ultrasonography was performed on all animals.

    • Main Results:

    • Ultrasonography identified bladder lesions in 38.46% of animals without hematuria and 33.33% with occult blood.
    • Abnormalities like irregular walls and loss of urothelium architecture were noted across all groups, including healthy animals.
    • Multifocal and Grade I lesions were most common, indicating subclinical changes.

    Conclusions:

    • Ultrasonography is an efficient tool for early detection of bovine enzootic hematuria.
    • The technique can identify pre-clinical BEH cases, enabling timely intervention.
    • US facilitates easy and early identification of BEH, improving herd health management.
