Which is not a cytopathic effective of virus?
**Core Concept**
The cytopathic effect (CPE) of a virus refers to the damage or destruction of host cells caused by viral infection. This can manifest as cell lysis, rounding, or fusion, and is a key indicator of viral replication and pathogenesis.
**Why the Correct Answer is Right**
Cytotoxic effects are not exclusively cytopathic. **Cytotoxic effects** can be caused by non-viral agents, such as chemicals or drugs, which damage cells without necessarily replicating within them. In contrast, cytopathic effects are typically a direct result of viral replication and the subsequent disruption of cellular processes.
