Micro 42: Adenoviruses

Clinical Deep Dives · Feb 23, 2026 · 41m

This episode explores adenoviruses, medium-sized, non-enveloped double-stranded DNA viruses known for environmental resilience and broad tissue tropism. Drawing from Murray’s Chapter 42, it examines how structural stability supports widespread transmission.

The narrative begins with viral architecture: icosahedral symmetry with distinctive fibre projections that mediate cellular attachment. Their lack of an envelope makes them resistant to drying, detergents, and environmental stress - enabling efficient spread in community settings.

Clinically, adenoviruses are associated with:
