[Study on the morphological processing of classical swine fever virus in cultured cells]
Abstract:
An infected mode between the Thiverval strain and Chinese strain of CSFV and MPK cells are established. The morphological structure and processing of different strains(T strain, C strain and F strain) of CSFV were studied by ultra-thin section electron microscopy. The virions of CSFV are roughly round and approximately 70 nm in diameter with a 40 nm core, and are wraped by membrane. The distinctive pathway of the maturation and release of CSFV are observed. Virons on different deverloping state and the pathologic changes of host cells have also been reported in this paper.
Insights
This study visualizes the structure and release of Classical Swine Fever Virus (CSFV) strains using electron microscopy. Findings reveal CSFV virion morphology and distinct maturation pathways within host cells.
Area of Science:
- Veterinary Virology
- Cell Biology
- Microscopy
Background:
- Classical Swine Fever Virus (CSFV) causes significant economic losses in swine populations worldwide.
- Understanding CSFV replication and structure is crucial for developing effective control strategies.
Purpose of the Study:
- To investigate the morphological characteristics and maturation processes of different CSFV strains (T, C, and F strains).
- To observe the distinct pathways of CSFV virion maturation and release.
- To document the pathological changes in host cells infected with CSFV.
Main Methods:
- Establishment of infected cell culture models using Thiverval and Chinese strains of CSFV with MPK cells.
- Ultra-thin section electron microscopy for detailed ultrastructural analysis of CSFV virions and infected cells.
Main Results:
- CSFV virions are approximately 70 nm in diameter, roughly spherical, with a 40 nm core, enclosed by a membrane.
- Distinctive pathways for CSFV maturation and release were observed.
- Pathological alterations in host cells and virions at different developmental stages were documented.
Conclusions:
- The study provides detailed ultrastructural insights into CSFV morphology and replication.
- Electron microscopy effectively visualizes CSFV maturation and release mechanisms.
- Findings contribute to a better understanding of CSFV pathogenesis at the cellular level.
