PIN WORM, 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 a.n.u.s. 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 r.e.c.t.u.m. When this has been expelled, follow with an injection per r.e.c.t.u.m 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 r.e.c.t.u.m. 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 a.n.u.s.
POLL EVIL
Poll Evil is so-called because it occurs in the region of the poll. It is not a const.i.tutional 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 sinuses from forming, but when the cases are long standing and so-called pipes are formed, I would advise that you secure the services of an accomplished Veterinarian.
PETECHIAL FEVER
(Purpura Haemorrhagica)
CAUSE: Const.i.tutional weakness following some debilitating disease such as Distemper, Pink Eye, Catarrh and even following operations, when an animal becomes weak and from want of exercise, in which case it generally appears during his recovery. It is not infectious and cannot be transmitted by inoculations.
SYMPTOMS: There is a slight swelling of the limbs, more likely to be about the hocks. The swelling may disappear by exercising, but will soon return. The swellings present a very abrupt appearance, nearly the same as if a string were tied around the limbs and swell very quickly, and symptomatic of Purpura. Exudations take place in which, if on white limbs, you will see little red spots, from which a liquid is oozing. The swelling is very painful and the entire limb may be swollen. Small vesicles appear on the limbs and also in the mucous membranes, and it is well to look at the mucous membranes before giving your opinion, as you will, no doubt, detect these spots, which may extend into the lungs.
These spots increase and may run into each other. The mucous membranes of the nose may become a ma.s.s of corrupt matter. The upper lip may hang pendulous, which is due to the want of nervous stimulus. If the nostrils are swollen very badly, there is difficulty in breathing and if the animal is not able to take food, the symptoms are considered very bad.
The pulse varies much in some cases; although the swelling is very great, the pulse may not be more than forty or fifty per minute. The temperature is elevated one to three degrees above normal, there may be a coughing and a brownish colored discharge from the nostrils. The mouth and eyes become affected and, together with the discharge from the nose, the horse is a loathsome looking object. In milder cases the appet.i.te is retained, or the animal may take food one day and the next refuse it.
The bowels are constipated as a general thing in the first stages of the disease and the urine may be of a dark color, may even contain blood.
There may be a peculiar dropsical swelling of these petechial spots or it may show itself in connection with the eyes and there may be blood extravasation without outer symptoms. This disease may affect the bowels, liver, lungs, etc. The animal usually stands, perhaps from the difficulty in moving the limbs. It is necessary to watch the case closely for flies will attack him and he will be filled with maggots.
Sloughing may take place; the entire sheath or patches upon the body may slough off and there may be paralysis of the p.e.n.i.s.
TREATMENT: Place the animal in a clean, light, comfortable stall. If the weather is cold, blanket. The following medicine is recommended because of its particular effect on the blood in this disease: Chlorate of Potash, eight ounces; Iodide of Potash, eight ounces; Quinine Sulphate, eight ounces. Make into thirty-two capsules and give one capsule every six hours. Also administer one ounce capsules filled with Spirits of Turpentine three or four times a day. Moisten the capsules with Sweet Oil and give with capsule gun. Feed hot bran mashes containing two or three ounces of pure Flaxseed meal. Also, feed vegetables, green gra.s.s, if possible.
