Micro 45: Parvoviruses
Episode Description
This episode examines parvoviruses, the smallest human DNA viruses. Drawing from Murray’s Chapter 45, it focuses on how structural simplicity results in highly selective cellular targeting.
Parvoviruses are non-enveloped, single-stranded DNA viruses that require actively dividing cells for replication. Their dependence on host DNA polymerase confines them to tissues with high cellular turnover.
The clinical focus is Parvovirus B19, which infects erythroid precursor cells in the bone marrow. The consequences vary by host context:
* Erythema infectiosum (fifth disease) in…
