TREATMENT.—Medical treatment is unsatisfactory. The disease will be prevented to a considerable extent by giving animals plenty of salt and in the marshes containing pools of water introduce or plant carp, frogs and toads into the infected tracts. These will destroy the young parasites and feed upon the snails which serve as their intermediate hosts. Or, prevent the cattle from grazing upon swampy marshes by fencing them out. FOOT AND MOUTH DISEASE. (_Infectious Aphtha—Epizootica Eczema_) CAUSE.—This disease is produced by a specific agent or germ, the exact nature of which is not known. It will pass through the Berkfelt filter, which is the most minute filter known to science, and is therefore known as a filterable virus. This is an eruptive fever and belongs to the class of Exanthematous diseases such as smallpox, measles, scarlet fever, etc. Every outbreak starts from some pre-existing infection. The infection is distributed by manure, pastures, barnyards, hay, drinking troughs, box cars, ships, boats which have been previously occupied by animals affected with this disease, travel over public highways or man may carry the infection of this disease on his clothing and transmit it to healthy cattle, etc. Foot and Mouth Disease not only affects cattle, but attacks a variety of animals, as the horse, sheep, goat, hog, dog, cat, also wild animals as buffalo, deer, antelope, and man himself is not immune from this disease. Children also suffer from Foot and Mouth Disease, resulting from drinking unboiled milk from infected cattle. Therefore, when purchasing cattle be very careful, as you may be buying an infectious disease. Keep the newly purchased animals to themselves for two or three weeks, if possible. This will give ample time for the majority of infectious diseases to develop. SYMPTOMS.—The disease usually makes its first appearance in three to six days after being exposed, by chilling, rise of temperature, and in a day or so pustules varying in size from that of a pin head to that of a pea appear. They appear upon the inner surface of the lips, gums and upper surface of the tongue. The feet also become affected between the digits. The udder usually becomes affected, especially in milking cows. As soon as this disease becomes well established the affected animal evinces great pain when attempting to eat. The animal generally refuses food. In many instances they shut and open the mouth with a smacking sound owing to the stringy saliva flowing from the mouth. The ulcers in the mouth continue to enlarge until they attain the size of one-half to two inches in diameter. The mucous membrane covering these ulcers breaks and a watery discharge escapes. In a few days the surface of the ulcers takes on a whitish appearance. The same changes take place in the feet and the animal becomes very lame and the udder very much swollen, the ulcers discharge, etc.
