  • Adenoviridae
  • May cause necrotising bronchiolitis in immune-deficient foals (Arabian foals)
  • Grossly:
    • Atelectasis and consolidation of lobules in cranioventral region
    • Mucopurulent exudate in airways
  • Histologically:
    • Severe bronchiolitis, necrotising -> proliferative
    • Bronchiolar obstruction by sloughed debri and neutrophils -> alveolar atelectasis
  • May lead to secondary bacterial infections
