    Area of Science:

    • Virology
    • Cell Biology
    • Microscopy

    Background:

    • Maedi-Visna virus (MVV) is a significant pathogen affecting sheep and goats.
    • Understanding MVV particle morphology is crucial for developing effective control strategies.

    Purpose of the Study:

    • To elucidate the ultrastructural characteristics of Maedi-Visna virus (MVV) particles.
    • To investigate the morphology of MVV during its replication cycle within host cells.

    Main Methods:

    • Ultrastructural analysis using electron microscopy.
    • Isolation and purification of MVV particles from cell culture fluids.
    • Infected cell culture examination.

    Main Results:

    • MVV particles are enveloped with surface projections and possess a distinct conical or ovoid core.
    • The core encloses a small, electron-dense nucleoid visible in ultrathin sections.
    • Budding structures and intermediate viral maturation stages were observed at the cell membrane.

    Conclusions:

    • The study provides detailed ultrastructural insights into MVV particle assembly and maturation.
    • Morphological characterization aids in understanding MVV's replication and potential therapeutic targets.
