GUTTUROMYCOSIS OF SOUPEDS. 



Aspergillus. Complications, ulceration, lesions of adjoining parts, food 

 in lungs, hepatization, gangrene. Treatment, by incision, sulphur dioxide, 

 iodine. 



Rivolta and Bassi have found in the guttural pouches of horses 

 and a mule, an advancing ulceration of the mucosa partially cov- 

 ered with crusts composed largely of the mycelium, conidia and 

 spores of Aspergillus or a closely allied fungus. In the mule the 

 ulcer had opened into the carotid artery causing a profuse epis- 

 taxis. In the three horses there was dysphagia, and the food, 

 descending to the lungs, had caused pulmonary hepatization and 

 gangrene. The description of the ulcers led Raillet to infer the 

 existence of glanders and. that the presence of the aspergillus 

 was accidental, rather than a causative factor. In parallel cases 

 the opening of the guttural pouch and injection with sulphurous 

 acid solution or dilute solution of iodine would be appropriate 

 treatment. 



TRACHEITIS. 



Primary inflammation of the trachea is rare, the disease when 

 found being usually an extension from the throat or bronchia, 

 in which the morbid process attains a greater intensity than in 

 the comparatively straight, roomy tube of the trachea, and these 

 usually give their names to the affection — laryngitis, bronchitis. 



Yet there are cases in which tracheitis will reach a high type, 

 and in all cases of extension of inflammation from above or below 

 the secondary disease — tracheitis — partakes of the character of 

 the primary one. Thus the tracheitis may be simple inflamma- 

 tion from mechanical, thermal or chemical injury ; or it may be 

 microbian, the weakened mucosa being attacked by saprophytic 

 bacteria ; Or it may be croupous ; or it may be diphtheritic ; or 

 parasitic (from sclerostoma, strongylus, filaria, linguatula, acar- 

 us, actinomyes or aspergillus) ; or it may be from the growth 

 of a neoplasm, benign or malignant ; or it may be specific (gland- 

 ers, sheep-pox, tuberculosis, strangles, contagious pneumonia or 

 influenza). 



Lesions. In the simple inflammation the ramified redness be- 

 trays the general congestion, but there may be petechise, a
