diseases of domestic animals 577 



Dysentery. 



Common in new-born, especially calves, when it is usually fatal. Prevent 

 by antiseptic treatment of aborting and parturient cows; by isolation of 

 patients and disinfection of their discharges; by segregation of cows about 

 to calve. Add formalin to the milk (Ttl,v-x to the gallon). Treatment of 

 little value in calves. In other animals, give purge, calomel, or magnesium 

 sulphate, or castor oil. Ipecac is a specific, especially Dover's powder. 

 Irrigations of rectum with creolin, or lysol, or silver nitrate. Internally, 

 opium with astringents, as: lead acetate, white oalc, catechu, kino, tannic 

 acid, hematoxylon. Rest; external warmth; and diet. Antiseptics: naphta- 

 lin, turpentine. Arsenic. 



Dysentery, Chronic Bacterial, of Cattle. Johne's Disease. 



Treatment is chiefly propliylactic. Isolate and destroy diseased animals. 

 Feces burned or buried deeply. Scrub and scrape fecal contamination from 

 barns and apply quicklime to floors and 3 per cent, formalin to walls and 

 whitewash containing the same. Internally, salol, bismuth subnitrate, tur- 

 pentine, etc., have little but temporary effect, as the disease is fatal. 



Dyspepsia. See Indigestion. 



Dyspnea. See Larynyitis, Broken Wind, Croup, Asthma. 



Pulmonary and cardiac: Nitroglycerin, nitrites, chloroform inhalation or 

 morphine in asthma or angina pectoris. 



In chest diseases, counter-irritation externally. Tracheotomy in mechanical 

 obstruction. Treat causal disease. 



Eclampsia. See Convulsions. 



Ecthyma in Horses and Sheep. 



Deep-seated pustules leading to formation of dark crusts, communicated 

 by contact with other animals, or by brushes, harness, or objects touching 

 the lesions. Isolate patients and secure cleanliness and proper hygienic 

 surroundings. Give tonics, bitters and good feeding. Remove crusts with 

 soap and water. Apply to lesions, salve containing salicylic acid (gr.xv-gi) 

 in zinc ointment; or, when animal can not lick it off, hydrargyrum ammo- 

 niatum (gr.v-gi) in zinc ointment. Ulcerations are treated with Peru balsam 

 covered with zinc ointment. Disinfection of premises and utensils. 



Eczema. 



In Dogs — Avoid water except to remove crusts after soaking in sweet oil 

 for 24 hours; in chronic cases, shampoo skin with green soap and water; clip 

 hair; employ muzzle or bandaging to prevent biting and scratching and 

 avoid external preparations which will poison if swallowed. In acute eczema, 

 carron oil or calamine lotion. In moist stage, zinc oxide ointment after the 

 application of black wash. In weeping patches, silver nitrate solution (2-6) 

 per cent, after cleansing with hydrogen dioxide. If suppuration, astringent 

 dusting powders: bismuth, starch, dermatol, glycerite of tannin, and use 

 bacterins of pus cocci prepared for such cases. With much itching, zinc 

 ointment with creolin (2 per cent.). In chronic eczema with scaly, thick- 

 ened skin, tar ointment, oil of cade in olive oil (1-8), or with zinc ointment 

 (1-8). Relieve constipation by cascara sagrada; give liver occasionally and 

 dog biscuit. Avoid fleas, dirt, friction. In acute cases, bread, soup or milk 

 and avoid oatmeal; starving in overfed animals, and 2-3, compound cathartic 

 piUs. Fowler's solution in chronic form. 



In the Horse — In the scaly form (wrongly styled psoriasis), thorough 

 grooming and destruction of parasites. Remove scales by soaking in olive 

 oil and washing. Apply oil of cade, liquid tar or creolin in alcohol (1-10). 

 Pustular form on mane and tail, avoid constant wetting and common soap; 

 clip hair; and apply hydrogen dioxide and 5 per cent, silver nitrate solution 

 and dust with tannic acid and iodoform (1-3), or use tar ointment. In 

 eczema of heels (grease), in acute stage apply zinc ointment, or white lotion, 

 or pink ointment. In later stages, with moisture and scabs, cleanse and 



^ apply balsam of Peru, wool dressing and bandage, or tannic acid and iodo-
