Pharyngitis

Introduction

For an overview of respiratory infections see Respiratory System Inflammation - Pathology

• Pharyngitis is often a part of upper respiratory and/or alimentary inflammation
• May cause
  • Obstruction to airflow
  • Aspiration pneumonia
• Acute inflammation passes through the same stages as in rhinitis

• In pigs, foreign material may lodge in the posterior diverticulum of the pharynx and cause inflammation, potentially perforation (also accidental in sheep during drenching) and fatal cellulitis
  • Inability to swallow due to the swelling may also be fatal

• In young thoroughbred horses equine chronic pharyngitis and lymphoid hyperplasia occurs due to chronic exposure to infection
