Infectious DNA from cells infected with feline syncytium-forming virus (Spumavirinae)
The Journal of General Virology
|September 1, 1977
Abstract:
DNA isolated from cells infected with FSFV (a foamy virus) is infectious when tested on susceptible cells. The virus produced by this infectious DNA is identical to the original infecting virus in terms of plaque and virion morphology and serology.
Insights
Infectious DNA from foamy virus (FSFV) can replicate the virus in susceptible cells. The resulting virus is identical to the original, confirming DNA infectivity.
Area of Science:
- Virology
- Molecular Biology
- Genetics
Background:
- Foamy viruses (FSFV) are retroviruses known to infect various cell types.
- Understanding the mechanisms of foamy virus replication is crucial for studying viral pathogenesis.
Purpose of the Study:
- To determine if DNA isolated from FSFV-infected cells is infectious.
- To characterize the virus produced from infectious DNA.
Main Methods:
- Isolation of DNA from FSFV-infected cells.
- Infection of susceptible cells with the isolated DNA.
- Analysis of the produced virus for morphology and serology.
Main Results:
- DNA isolated from FSFV-infected cells demonstrated infectivity in susceptible cells.
- The virus produced from this infectious DNA was indistinguishable from the original FSFV.
- Identical plaque and virion morphology, as well as serological properties, were observed.
Conclusions:
- The study confirms that DNA from FSFV-infected cells is infectious.
- This infectious DNA can generate progeny virus identical to the parent virus.
- These findings contribute to the understanding of foamy virus replication and genetic stability.
