Tracheitis (Image sourced from Bristol Biomed Image Archive with permission)

• Inflammation of the trachea - tracheitis

• Tracheitis can occur as part of an extension of an upper or lower viral or bacterial respiratory infection
  • eg: IBR, FHV-1, EHV-1, influenza viruses
  • eg: Bordetella bronchiseptica, Strep. equi. subsp. zooepidemicus/equi, Pasturella multocida
• May cause
  • Obstruction to airflow
  • Aspiration pneumonia
• Acute inflammation passes through the same stages as rhinitis

Chronic polypoid tracheitis

• In dogs and cats
• Secondary to chronic inflammation
