Glanders
This is one of the most destructive of diseases with which the horse
family is afflicted, and one that has set the best veterinary skill of
the world at defiance. A remedy for it has yet to be discovered. I have
deemed it proper here, however, to carefully describe its symptoms, and
to recommend that all animals showing symptoms of it be kept by
themselves until their case be definitely ascertained. When you have
ascer
ained to a certainty that they are afflicted with the disease,
destroy them as quick as possible. See, too, that the place where they
have been kept is thoroughly cleansed and sprinkled with lime, for the
disease is contagious and the slightest particle of virus will spread it
anew. Farcy is but one stage of this terrible disease, but is not
necessarily fatal while in this stage. It should, however, be treated
with great care and caution. Farcy can also be conveyed to others by
inoculation. Any one who has had the field for observation the author
has for the last four years, would become convinced that the
recommendations I am about to make describe the only course to be taken
with this contagious disease. The number of its victims under my
observation were counted by thousands. All that can be done is to
prevent, if possible, the disease taking place, and to destroy when
ascertained to a certainty that the animal has contracted it. I would
say here, however, that this subject will soon be thoroughly handled in
a work soon to be published by Doctor Braley, head veterinary surgeon of
the army. He will undoubtedly throw some light on the subject that has
not yet appeared in print.
SYMPTOMS.
First:--When it appears in a natural form, without the agency of
contagion or inoculation, dryness of the skin, entire omission of
insensible perspiration, starring of the coat. Sometimes slight
discoloring can be observed about the forehead and lower part of the
ears. Drowsiness, want of lustre in the eye, slight swelling on the
inside of the hind legs, extending up to the bu-boa. This condition of
things may continue for several days, and will be followed by
enlargement between the legs. The inflammation incident to this may
entirely subside, or it may continue to enlarge, and break out in ulcers
on the lactiles of the lymphatic, which accompanies the large veins.
In the last case it has appeared in the form of Farcy. This being the
case, the countenance assumes a more cheerful look, and the animal
otherwise shows signs of relief from the discharges of poisonous matter.
If it remain in this state, death is not generally the result. If the
system be toned up it will sometimes heal, and the animal will seem to
be in a recovering state of health. Yet, from watching the symptoms and
general health of the animal afterwards, you will be convinced that the
disease is only checked, not eradicated. Acting in the system, it only
waits a favorable opportunity to act as a secondary agent in colds,
general debility, or exposure, when it will make its appearance and
produce death.
But in the first case, as shown by the swelling in the hind legs, if the
swelling disappear, and general debility of the system continues; if the
eyes grow more drowsy, and discharge from the lower corners; and if this
is followed by discharge from the nostrils, slight swelling and
hardening of the sub-maxillary glands, which are between the under jaws,
then it is clearly developed glanders. All the glands in the body have
now become involved or poisoned, and death must follow in the course of
ten or fifteen days, as the constitution of the animal may not be in a
condition to combat the disease.
If this disease be annoyed by inoculation from the farcy heads of
farcied animals into suppurating sores on other animals, it will be very
slow in its progress, especially if it attack the other in a region
remote from the lymphatic. If in a saddle-gall, it will make sores very
difficult to heal. If there is any such thing as checking the disease in
its progress, it is in these three cases.
I have observed that when it has been taken in a sore mouth it has
followed down the cheek to the sub-maxillary gland, and ended in a clear
case of glanders or farcy. There is another form in which this disease
can be taken, and which is, of all others, the most treacherous and
dangerous, yet never producing death without the agency of other
diseases--always carrying with it the germs of infection, and ready to
convey it to debilitated subjects and cause their death. The animal will
still live himself, and show no sign of disease further than I am about
to describe in the position. It is that which is taken in at the
nostrils and attacks the sub-maxillary glands, which become enlarged and
will remain so. When these become overloaded there will be a discharge
at the nose. That being thrown off, it may be some time before any
further discharge will be seen from the same source. In some cases, when
the discharge is constant, this can be easily distinguished from gleet
or ozena, from the healthy and natural appearance of the membranes of
the nose, which at first are pale, then become fiery red or purple. In
gleet the discharges from the nostrils, as in ozena, are of a very light
color. In glanders they are first of a deep yellow, then of a dirty
gray--almost slate color.
Mules affected with glanders of this kind, although it may seem hard
from their otherwise healthy appearance, should be destroyed. They
indeed carry with them the germs of infection and death, without any
visible marks in their appearance to warn those who have the care of
animals against their danger.
