PURULENT COLLECTION OF GUTTURAL POUCHES.

strangles. When once the inflammation has started in the walls 

 of these pouches, the muco-pus secretion accumulates within, 

 maintains the pathologic state which has given rise to it, and 

 changes it into a chronic state. As glandered horses are now, 

 as a rule, destroyed as soon as the disease is recognized, collections 

 in the guttural pouches, of a glanderous nature, are altogether 

 exceptional. 



The disease is usually localized in one of the pouches ; some- 

 times both are infected. 



Symptoms. The principal symptom of purulent collection 

 in the pouches is an intermittent discharge, appearing, as a rule, 

 only at meal-times, during mastication and deglutition of food, 

 particularly while swallowing liquids (Delafond). Sometimes it 

 appears also during exercise, but is then much less abundant. It 

 is an odorless, generous discharge, consisting of a liquid part, 

 holding yellowish-white flakes of a variable size in suspension ; it 

 runs out of the lower nasal groove, without agglutinating the 

 hair, and without forming crusts. When the purulent collection 

 is double, the discharge is always bilateral ; when it is single, it 

 runs sometimes through both nostrils, sometimes only through 

 that corresponding with the affected guttural pouch. 



The subglossal ganglions are always more or less tumefied. 

 They form an extended gland, mobile under the skin and deeper 

 parts, less voluminous, less irregular, and much less hard than 

 the gland of glanders. 



The parotid region is often the seat of a more or less pronounced 

 tumefaction, accompanied or not by heat, and of abnormal sensi- 

 bility. 



When purulent collection of the guttural pouches coexists 

 with pharyngitis or strangles, and if the orifice of communication 

 of the diseased pouch with the Eustachian tube is obstructed, the 

 abscess becomes voluminous, and interferes with deglutition and 

 respiration by a constant pressure it exercises upon pharynx and 

 larynx. The guttural pouches, if distended to excess, may burst 

 under the repeated efforts of deglutition and sneezing ; in other 

 cases they produce spells of suffocation and asphyxiation. Death 

 may also occur through gangrenous pneumonia, by the introduc- 

 tion of food into the respiratory organs. 



The disease has no tendency to resolution. Left to itself, it 

 persists through life. The purulent matter will then thicken,
