MYCOTIC STOMATITIS. 541 



tion, distinguish between this affection and foot-and-mouth disease. 

 The erosions of the mouth are not so extensive and they heal more 

 rapidly in mycotic stomatitis. The swelling of the feet and stiffness 

 of the animal are also more marked in mycotic stomatitis. 



ERGOTISM. 



The lesions resulting from ergotism may be differentiated from 

 those of mycotic stomatitis by the lack of ulcerative eruptions in the 

 mouth and by the location of the lesions at the tips of the ears, end of 

 the tail, or upon the lower part of the legs, usually below the knees or 

 hocks. The lesions of ergotism do not take the form of ulcers or 

 festers, but the end of the limb affected is diseased " in toto " and the 

 eruption extends entirely around the limbs, followed soon afterwards 

 by a distinct line of demarcation between the healthy skin above and 

 the diseased below. The absence of suppurating sores between the 

 claws and on the mucous membrane of the mouth, the knowledge that 

 the lesion upon the limb in question extends uninterruptedly around 

 it, and the presence of ergotized seeds in the hay or grain fed the 

 animals should point conclusively to a diag-nosis of ergotism. 



FOUL FOOT. 



In foul foot, or ground itch, of cattle, the inflammation of the skin 

 and toes usually affects but one foot. It begins as a superficial 

 inflammation followed by sloughing, ulceration, and the formation of 

 fistulous tracts which may involve the tendons, bones, and joints. 

 The mouth remains unaffected, and the presence of the disease may 

 be traced to filth and poor drainage. 



NECROTIC STOMATITIS. 



In necrotic stomatitis (calf diphtheria) there is a formation of 

 yellowish cheesy patches in the mouth without any lesions of the 

 feet or udder. It affects sucking calves chiefly, and is caused by the 

 Bacillus necroyhoTus. 



TREATMENT. 



The treatment of mycotic stomatitis should consist in first remov- 

 ing the herd of cattle from the pasture in which they have been 

 running. The affected animals should, if it is possible, be brought 

 to the barn or corral and fed on soft, nutritious food, such as bran 

 mashes, ground feed, and gruels. A bucket of clear, cool water should 

 be kept constantly in the manger, so that the animal may drink 

 or rinse the mouth at its pleasure; and it will be found beneficial 

 to dissolve 2 heaping tablespoonfuls of borax or 1 tablespoonful of 

 potassium chlorate in each of the first two buckets of water taken
