COMMON DISEASES OF SWINE 347 



disease in "The Gazette " of November 12, 1914. The following 

 points are taken from the article in question : " So highly con- 

 tagious is the character of foot-and-mouth disease that its eradica- 

 tion and control necessitates instant isolation and slaughter of 

 affected animals, deep burial of the carcasses in quicklime, thor- 

 ough cleansing, disinfection, and whitewashing of the infected 

 premises, strict quarantine of all infected stables, farms, and 

 areas, restriction of the movement of animals and pasteurization 

 or boiling of milk." Hogs usually take the disease from cattle, 

 hence it is important to be able to recognize the disease in any 

 class of stock. 



Symptoms. — Following are some of the characteristic symp- 

 toms as given by Dr. Alexander : " The temperature of the cow 

 rises 2 to 4 degrees, the pulse accelerates, appetite diminishes, 

 shivering may be seen, while the hair is roughened, the muzzle 

 hot and dry, the teats and membranes of the mouth become red, 

 saliva drools or froths from the mouth, and a characteristic smack- 

 ing of the tongue is heard. Tenderness of the feet is shown by 

 lameness and soreness. In two to three days large and small 

 vesicles (blisters) develop on the inner siirface of the lips and 

 cheeks, the gums, palate, and top and borders of the tongue. 

 . . . Simultaneously, with the eruption of vesicles upon the 

 mucous membranes of the mouth, vesicles may develop in cattle 

 on the muzzle, and at the base of the horns, and in hogs on the 

 snout. . . . Sheep, goats, and swine do not commonly show severe 

 lesions of the mouth when attacked by the disease. In these 

 animals the feet are most affected." 



Dr. Charles F. Lynch, in " Diseases of Swine," says : " In 

 an outbreak of foot-and-mouth disease, cattle are usually first 

 affected, and the disease may then spread to the swine. The 

 characteristic symptoms of this disease are the finding of large 

 numbers of vesicles or blisters between the toes and along the 

 lower part of the mouth. There may also be some blisters in the 

 mouth and on the tongue."
