NOC CHOLERA DIAGNOSIS
SYMPTOMS AND NEEDED TREAT
MENT OF RECOGNIZED FORMS.
BY c. e. Wilson, Assistant in Veter-
mary Science, University
of Missouri.

Mr.. C. e. Wilson, who is at pres
ent assisting in the production OF
hog cholera serum at the Missouri
College of Agriculture, gives the fol-
lowing description of the symptoms
and post mortem indications or hog
cholera.
1.-The symptoms are not the same
In any two hogs. and sometimes they
are quite different. But some OF the
Seneral indications are always pres
ent when hog mas cholera There
are two general forms OF cholera
One is the acute form, which causes
the death OF the pig in a few days.
The other is the chronic form, with
while and finally get we'll. However,
with which hog may linser quite
while one hog man have the CHROME
and less dangerous form. another hog
exposed TO Infection from the hrst
may take the acute form and die IN
4 day or two.
With both forms of cholera. the
first outward symptom is weakness
and a totterng. wabbly gait. Some
times there will be profuse dlarr-
hoea, but in the same lot some 9th
ers may be constipated. Sometimes
also. there is gummy exudate
around this eyes.
The chief characteristic OF cholera
Is the formation OF nemmhoraglc
spots in various parts OF the BODY.
This may sometimes be seen on the
skin of the belly, showing as specK-
led red. This is about the surest
sign that can be detected from the
outside, but it cannot be seen except
IN light-skinned hogs This is caused
by the bursting Of the small capll-
larieg or blood vessels in the skin.
Another indication which is almost
certain for cholera is the spreading,
infectious nature of the disease. 1t
will be in the whole herd II one ami
NAL has 1t and runs with the others.
II hog has died and cholera is
suspected, the carcass should be care
fully examined for indications OF the
disease. AS in the case Of symptoms,
some may be found in one hog, and
different indications in another. But
some are sure to be present IT the
hog died of cholera.
The carcass should be opened along
the median line of the belly. The
LAYER which lies inside the body cav
ity, the peritoneum, may have red
specks or splotches on 1t. This
would indicate the disease. The
glands in the throat should be ex
amined. They will sometimes be
speckled and hemmhoragic-that is
the tiny capillaries which carry thell
blood supply will be ruptured. There
is one pair of glands in the throat
which is never affected in cholera
but is with tuberculosis.
The next place to examine will be
the pleural cavity or the division Of
the body which contains the lungs
and heart. In case of a death from
cholera, the lungs will often be con
gested and parts of them filled witt
blood. The healthy lung will f1oa
in water, but congested one VII
sink. There will be splotches ant
redness scattered over the surface
Sometimes the hog will have pneu
monia as a result of the cholera. ant
this will be seen in the filled, con
pested condition Of the lungs. II

and spread out. The splotches, hoy
ever. will not wash off.
The above indications are mol
likely to be found in the acute for
Of cholera, and are associated wit
a rapid working action Of the diseat
and rather sudden deaths. 1t is IL
most virulent form and should
carefully guarded.
In the chronic form almost any
the symptoms may be found, b,
there are likely to be fewer indie
lions. The intestines. however, w
likely show serious ulcers. The

The diseased carcass should

hogs. Also 1t is well to rememb
that there may be sufficient infecti'
carried on the shoes to give the d
ease to other hogs.
