    Diagnosis of contagious ecthyma (orf) in a farmer was confirmed by identifying viral particles using electron microscopy. This negative staining method offers rapid diagnosis for suspected orf cases, especially in fresh lesions.

    Area of Science:

    • Veterinary Virology
    • Dermatology

    Background:

    • Contagious ecthyma, also known as orf, is a zoonotic viral skin disease.
    • Diagnosis is often based on clinical signs, but laboratory confirmation is crucial.

    Observation:

    • A 33-year-old farmer presented with clinical signs suggestive of contagious ecthyma.
    • Electron microscopy was employed to examine lesion samples.

    Findings:

    • Viral particles consistent with orf virus were identified using the negative staining electron microscopy technique.
    • Detection of viral particles was more successful in fresh lesions compared to older ones.

    Implications:

    • Negative staining electron microscopy is proposed as a valuable tool for the rapid diagnosis of contagious ecthyma.

  • Early diagnosis facilitates prompt management and helps control disease spread.
  • Understanding orf virus's classification aids in epidemiological studies and prevention strategies.
