Pig Pharyngitis
[Overview] This disease is caused by catching a cold, or by coarse, hard, sharp objects injuring the pharyngeal mucosa, leading to inflammation of its surface layer and deeper layers. Clinically, it is characterized by difficulty swallowing and stiff head and neck. [Etiology/Pathogen] It is caused by pigs catching cold due to factors such as a cold pig house, exposure to cold air, and insufficient bedding; other causes include inhalation of dust or irritating odors, weak body resistance, injury to the pharynx by coarse, hard, sharp objects, rough administration of medication through the mouth with a stomach tube, feed that is too hot or frozen, or secondary to streptococcal disease.
