NASAL GLEET 



Is the name applied to a chronic glairy discharge from one or both 

 nostrils, of a whitish muco-purulent matter, the result usually of 

 neglected catarrh. The general health of the animal does not seem 

 to suffer ; he looks well, feeds well, and works well. 



Nasal gleet is not an uncommon disease, and many horses 

 have been destroyed, supposed to be affected with glanders, when 

 in reality they were only suffering from nasal gleet. It is on this 

 account that I have been so explicit in describing glanders. 



Causes. It is very often the result of catarrh in a chronic 

 form, as stated, induced by further exposure to cold, and want of 

 a proper supply of nutritive food. It may also occur in cases 

 where it cannot be traced to a catarrhal attack of the air passages ; 

 and it occurs oftener in aged than in young animals. 



Symptoms. The first noticeable symptom is a yellowish 

 discharge from one or both nostrils. The lining membrane of the 

 nose (schneiderian) is altered in color ; it becomes of a pale leaden 

 hue, but does not exhibit ulcerative patches, as in glanders. The 

 discharge may vary both in quantity and quality. It is often 

 retained for some time within the sinuses, and comes away in 

 considerable quantities. In other cases the discharge is continuous, 

 and collects about the nostrils ; the sub-maxillary gland, in cases 

 of long standing, becomes tumefied, but not adhering to the bone 

 as in glanders ; the frontal and nasal bones are affected, and pre- 

 sent an enlargment or bulging out over the seat of the disease. If 

 tapped with the point of the finger, a dull, heavy sound is pro- 

 duced, showing that matter has collected within the sinus. In 

 ordinary cases it is a long time before it materially affects the 

 horse in his working capacity. When the bones are greatly dis- 

 eased, and the matter collects within the nasal sinuses, it interferes 

 with respiration, causing laborious breathing, 



Treatment. Although a formidable disease, even the worst of 

 cases may recover if properly treated. The successful treatment 

 in all cases where this disorder has existed, has been on the tonic 

 principle. Bteeding and pMiging are posativfely usurious.
