162 THEORY AND PRACTICE 



the form of a red limpid serum mixed with mucus. After a few 

 days this becomes muco-purulent and streaked with blood. If 

 you look into his nose you will notice a red local swelling elevated 

 at least 54 inch. This is the pustule of glanders, and when it 

 ruptures the hemorrhage causes the pus to be bloody. The 

 mucus from the nose is of a catarrhal nature, coagulated and 

 starchy. It has no actual diagnostic appearance, but it is sus- 

 picious because of its resemblance to melted butter. This sticky 

 discharge accumulates around the rim of the nostrils and dries 

 there more or less. This interferes with the respiration. The 

 horse blows his nose and a stringy discharge flips up and lodges 

 on the side of the face where it attracts dust and dirt. The 

 glandered horse always has a dirty face. The stall also will 

 be just as dirty. You can always tell a glandered horse's stall. 



In the course of a week the submaxillary lymphatics will 

 swell. They catch the debris and germs. As a rule they do 

 not suppurate. This symptom is not diagnostic, for you get the 

 same in chronic catarrh. 



The pustule in the nostril ruptures, eventually ulcerates. The 

 ulcer has an elevated, ridged edge with a depressed center. Ulti- 

 mately the whole mucous membrane of the nose has a mouse 

 eaten appearance. In a mild case, especially if the pustules form 

 high up in the nostril, the air passages become constricted and 

 we get wheezy breathing, but this is not diagnostic. 



Cough, accelerated breathing and pneumonia are the next 

 symptoms. The pneumonia is interstitial because it involves the 

 interlobular connective tissue. The lining of the bronchi becomes 

 ulcerated. In the course of a week we get cuticular manifesta- 

 tions, particularly in the inguinal region and at times in the pec- 

 toral. The legs are doughy and the nodular swellings discharge 

 and ulcerate. These ulcers do not heal, but remain in a state of 

 continual discharge until death. 



In such a condition the horse is dejected, hangs his head and 

 looks miserable. The discharge from the nose may become some- 

 what offensive in a late stage. The animal dies from collapse. 

 During the whole course of the disease the fever stays up to 102" 

 to 104° or even more. The pulse is increased in frequency and 

 decreased in size and strength.
