[Influence of a hypertonic medium on cell susceptibility to foot-and-mouth disease virus]
Abstract:
The influence of hypertonic medium on the relationship between two cell clones of IB-RS-2 swine line and the foot-and-mouth disease virus was studied. Although the number of infected cells was increased by the cell treatment with the hypertonic medium, before or during the time of virus adsorption and penetration onto the cells, showed by the plaque number, the viral replication was partially inhibited as showed by the plaque size as by the viral yield in one-cycle of infection. On the other hand, the cell treatment with that medium after virus adsorption and penetration time inhibited as the plaque number and size as the yield of the foot-and-mouth disease virus.
Insights
Hypertonic medium affects swine cells and foot-and-mouth disease virus (FMDV) interactions. Treatment before or during infection increases cell susceptibility but inhibits viral replication, while post-infection treatment reduces both infection and replication.
Area of Science:
- Virology
- Cell Biology
- Biochemistry
Context:
- Investigating the interaction between IB-RS-2 swine cell line and foot-and-mouth disease virus (FMDV).
- Examining the impact of hypertonic medium on cellular responses to viral infection.
Purpose:
- To elucidate how hypertonic medium influences FMDV infection dynamics in IB-RS-2 cells.
- To determine the effect of hypertonic treatment timing on viral adsorption, penetration, and replication.
Summary:
- Hypertonic medium treatment of IB-RS-2 cells before or during FMDV adsorption and penetration increased the number of infected cells (plaque number).
- However, viral replication, indicated by plaque size and viral yield, was partially inhibited under these conditions.
- Conversely, treating cells with hypertonic medium after FMDV adsorption and penetration inhibited both the plaque number and size, as well as viral yield.
Impact:
- Findings suggest hypertonic medium can modulate host cell susceptibility and viral replication differently based on treatment timing.
- This research provides insights into potential strategies for controlling FMDV spread by manipulating host cell environments.
- Understanding these host-pathogen interactions is crucial for developing effective antiviral interventions.
