PHARYNGITIS 541 



exposure to cold, inflammation of the mouth, swallowing of sharp- 

 pointed substances which scratch or injure the hning of the 

 pharynx, and the inhalation of irritating gases. The disease com- 

 monly follows stomatitis, and also commonly occurs in company 

 with laryngitis, which is described under Diseases of the Respir- 

 atory Tract. 



Symptoms. — Among the first symptoms to be noted of pharyn- 

 gitis is the fact that the animal takes food rather slowly and in 

 very small amounts. Especially will this be true with the hard 

 foods, such as corn. The animal has the appetite, but the diffi- 

 culty lies in inability to swallow. The pharynx by this time has 

 become so tender, painful, and swollen that it is almost impossi- 

 ble for the animal to swallow anything but liquids. As an ex- 

 ample of the great difficulty experienced in trying to swallow, 

 the animal will often take food into the mouth, chew it up, and 

 then throw it out of the mouth again, so painful is the attempt 

 at swallowing. 



The head and neck are held out stiffly, and when the animal 

 walks or moves about it holds the neck in a very stiff manner. 

 There is a considerable amount of swelling about the throat and 

 any movement of the head or neck is painful. The swallowing 

 even of water is quite difficult, and, as a result, the animal not only 

 refuses food, but also drinks but little water. The snout may be 

 placed in the water trough, and the mouth washed in the water, 

 but very little will be swallowed, as every attempt at swallowing 

 is accompanied by the most severe pain. 



The animals are usually restless, and may squeal and grunt 

 considerable in evidence of the pain which they are suffering. 

 Swallowing movements are made very frequently, due to the irri- 

 tation of the hning of the throat. Mucus collects in the mouth 

 and there may be considerable discharge of saUva from the jaws. 

 The eyes often appear red and watery. In some cases vomiting 

 may occur. 



In practically every case there is an associated inflammation 

 of the nose and larynx. This results in a discharge from the nose 

 and a pronounced cough. This cough is usually worse if the animal 

 comes out of a warm shed into the cold air. 



When the animal is caught, and an examination of the neck and
