RM, THREAD OR MAW WORM

(Oxyuris Curvilis)

This worm when full grown is about one and three-quarter inches in
length; its tail is thin and whip-like and head thick and terminating in
a curve somewhat resembling the crook of a stick. The presence of these
parasites may be detected by a light-yellow substance (the eggs of the
worms) which adheres to the skin below the anus. Pin Worms like Round
Worms frequently come away with the feces.

TREATMENT: Dissolve four tablespoonfuls Common Salt in one gallon of
warm water and inject it into the rectum. When this has been expelled,
follow with an injection per rectum of Turpentine, four ounces, to
one-half gallon Linseed Oil. Elevate the horse's hind quarters so as to
retain the injection longer. This will expel the worms and their eggs
that cling to the walls of the rectum. The worms sometimes make their
way so far forward that it is impossible to reach them with an
injection. In this case treat same as for Round worms.

Where there is irritation produced about the tail the horse continually
rubs and it is well to apply Mercurial Ointment to both tail and the
anus.

POLL EVIL

Poll Evil is so-called because it occurs in the region of the poll. It
is not a constitutional disease, but comes, no doubt, from well marked
causes, as from inflammation set up and involving the bones and muscles
in the region of the poll, and perhaps of the larger ligament. Owing to
the low vitality of the parts and the action of the head in taking food,
etc., the pus is apt to burrow deep into the muscles.

CAUSE: Direct or indirect injury. A common cause is striking the head
against a low doorway or an ill-fitting halter or bridle.

SYMPTOMS: Swelling just back of the ears on one or both sides of the
head. The animal stands with the nose out; slight heat in the parts,
pain on pressure. In the first stages, it is merely inflammatory action.
The second stage is suppuration, or there may be great swelling in some
cases when there is but little pus formed.

In other cases there is profuse suppuration and the pus makes its way
out and discharges to the surface and sinuses are formed, which extend
in various directions. Any abscess in this region is called Poll Evil.

TREATMENT: When the enlargement is first noticed in the region of the
poll, I would advise the following: Red Iodide of Mercury, four drams;
Lard, four ounces, rub in well over the enlargement and perhaps this
will prevent sin
