of becoming infected. Since the
organism is found in the urine and
faces of sick hogs, it is an easy mat
ter for an attendant of sick hogs to
carry it to neighboring herds on his
feet Stock buyers who visit all the
hog lots in the country can easily
carry it in this manner. Grows,
hawks. buzzards, sparrows, dogs, rab
bits, etc., may easily spread the dis
ease. The stream that runs through
an infected farm may carry it to
healthy herd. Everything that comes
in contact with the sick hogs becomes
contaminated with the germs. Re-
member that the ways for spreading
th disease are legion and that the
means of eradication are few, the
keynote of them all is cleanliness,
written in big letters.
SYMPTOMS.
The symptoms vary in different
forms of the disease. Briefly, they
are in the acute form as follows:
First symptoms of appetite,
vomiting, Inflammation of the mem
branes of the eyes and mating to-
gether of the eyelids. The animal
may be constipated, but diarrhoea
generally sets in within a short time
and the discharge from the bowels is
of grayiSh color or streaked with
blood, odor offensive. Diarrhoea
may be absent in some cases. Tenn
perature increases, sometimes cough
ing, purplish blotches are often found
on the skin in the region of the
TANKS and the abdomen and also on
the ears. The animal gets weak,
lies hidden in the litter and will rise
only when forced to do so. After
rising, it may walk, usually swaying
or reeling behind; it will go only a
short distance, then stop for fifteen
or twenty minutes. Death occurs in
from four to seven days. In the sub
acute and chronic forms the hog may
linger from seven to Il days. In
order to be sure of the disease,
post-mortem examination should be
made.
POST MORTEM APPEARANCE.
The following table shows the or
gans which should be examined when
hog cholera is suspected. A descrip-
ton of the appearance of the organs
In cases of cholera is given after each
organ. 1t must be remembered that
all of these post mortem appearances
may not be found in one hog. Those
in the skin, large intestine, small in
testine, spleen, kidneys and lungs are
the most diagnostic.
