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.—F'ollowing 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 davs large and small 
vesicles (blisters) develop on the inner surface 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.”
