(DNA VIRUSES) Lesson 6: Parvoviridae Flashcards

1
Q

General description of Parvoviridae

A

 Small, non-enveloped, single-stranded DNA viruses
 Icosahedral symmetry
 Replicate in the nucleus, form intranuclear inclusion bodies
 Require rapidly dividing cells for replication
 Stable in the environment
 Resistant to heat, solvents, disinfectants, and pH changes
