Viral Pathogenesis Flashcards
1
Q
What are the four types of virus infection in cells?
A
- Transforming/oncogenic
- Acute/lytic
- Latent/proviral
- Persistent/chronic/slow
2
Q
What are permissive cells?
A
Complete virus replication resulting in virus production
3
Q
What are non-permissive cells?
A
No virus growth and no virus production (i.e. BVD virus in canine cells)
4
Q
What are the four cytopathic effects of viruses? (morphological changes)
A
- Cell rounding (VSV)
- Cell fusion and syncytia (Herpes virus)
- Inclusion bodies (Rabies virus, Negri bodies)
- Vacuoles (BVDV)
