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 infections 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 ul
