Cytopathic

Definition

Cytopathic refers to the structural changes in host cells caused by viral invasion. These changes can result in cell damage or death, impacting the function of the infected tissues.

5 Must Know Facts For Your Next Test

1. Cytopathic effects are often used to identify viral infections in tissue cultures.
2. Common cytopathic effects include cell lysis, rounding of infected cells, and formation of syncytia.
3. The degree and type of cytopathic effect can vary depending on the virus and the host cell type.
4. Not all viruses cause cytopathic effects; some may lead to persistent infections without obvious cell damage.
5. Cytopathic effects can trigger the immune system to respond to viral infections.
