 DISEASES OF THE BUCCAL CAVITY. 



1. Catarrh of the Buccal Cavity. Stomatitis catarrhalis. 



(Stomafifis Simplex, Stomatitis Erythematosa, Maulcatarrh 

 [German].) 



Etiology. Catarrh of the buccal mucosa may occur pri- 

 marily after injury by sharp parts of plants, by pointed foreign 

 bodies, such as fragments of bones, nails, etc., also in conse- 

 quence of faulty teeth, improper bridle bits, by rough examina- 

 tion of the mouth. The buccal cavity of cattle may develop a 

 catarrhal or even an ulcerative inflammation after penetration 

 into the mucosa of licked up hairs or of the bearded grains of 

 barley. (Koiranski.) 



Scalding by hot feed (distillery slop, broth) or hot medicinal 

 applications may also cause inflammations. 



Chemical irritants ma}" likewise be the causative factors, 

 particularly such as are applied externally as medicines, and 

 may accidentally be licked up by the animal or otherwise come 

 in contact with the mucosa of the mouth. It sometimes occurs 

 that animals drink of solutions of carbolic acid or corrosive sub- 

 limate, prepared and used for purposes of disinfection. Occa- 

 sionally internal medicines, when used in too strong a concentra- 

 tion, may exert a caustic effect, and this is frequently the case 

 mtli tartar emetic. Some medicines, like mercury, iodine or 

 lead, may produce a catarrhal affection of the mouth after long- 

 continued internal use. This condition may also be produced 

 by strongly fermenting distillery slop, or other fermenting food 

 materials. The milk of animals suffering from diseases of the 

 udder, from foot-and-mouth disease, or from variola, produces 

 inflammation in the mouth of the sucking young. Further causes 

 of catarrhal inflammations are the poisons contained in such 

 plants as spurge, hemlock, mustard, ranunculacere, etc., occa- 

 sionally also Swedish clover and fresh, insufficiently dried hay.
