Introduction

Adenoviruses are so named for the tissue from which they were first recovered: human adenoid tissue. Since then they have been found in most species and are generally harmless.

Morphology

  • Stable, non-enveloped, resistant
  • Icosahedral virus:
    • Capsomeres at apices (12) carry a peripheral fiber with a terminal knob
    • Capsomeres on facets (240) do not

Virus by Species

Bovine adenovirus

Equine Adenovirus

  • Rarely causes primary disease
  • Exception: immune-compromised Arab foals (showing both B/T cell deficiencies), causing necrotising bronchiolitis

Canine Adenovirus 1 (Infectious Canine Hepatatis)

Canine Adenovirus 2 (Infectious Canine Laryngotracheitis)
