INDEX OF DISEASES AND REMEDIES 799 



ULCERS continued. 



Pare or scrape away unhealthy tissue. 



Apply iodoform, iodine, carbolic, and other antiseptics ; actual 



cautery. 



Glanders ulcers should not be treated. 

 URINARY DEPOSITS. See CALCULI. 

 URTICARIA. 



Surfeit ; Nettle-rash. An evanescent erythema of the skin, occasion- 

 alty of the mucous membranes, with circumscribed, itching, serous 

 elevations ; usually appearing and disappearing with equal rapidity. 

 Not infrequent in horses, dogs, and pigs ; rare in cattle or sheep. 

 Purgative medicine ; damp the skin repeatedly with an alkaline solution. 

 When rash persists or recurs give antacids ; attend to diet and cleanli- 

 ness of clothing, avoid washing with cold water. 



URETHRITIS. 



Catarrhal inflammation of the urethra ; discharge containing bacteria. 

 Prepuce and surface of penis may be affected. Not uncommon in 

 dogs and bulls ; contagious. 



Copper sulphate, zinc chloride, or silver nitrate injected in dilute warm 

 solution, 2 to 5 grains to an ounce of water, sol. resorcin 2 to 3 

 per cent. 



Thorough cleanliness. Diluents ; alkalies. 

 Copaiba and eucalyptus are useful anodynes and antiseptics. 

 Prevent occlusion by cautious introduction of clean catheter. 

 Persistent obstruction from inflammation or gravel in male sometimes 

 requires perineal opening. See URINARY CALCULI. 



UTERUS, INFLAMMATION OF. See METRITIS. 

 VAGINITIS. 



Infective inflammation of mucous membrane of vagina, sometimes 

 extending to uterus ; a frequent cause of sterility and abortion ; 

 contagious ; occurs in all females. 



Isolate affected animals, disinfect cowsheds, loose boxes, and attendants. 

 Irrigate vagina with antiseptic solutions, corrosive sublimate, protargol, 



lysoform, or lysol. 

 Disinfect sheath of bull that has served affected cow ; repeat disinfection 



after each service, using warm solution of lysol (two per cent). 

 Cows affected with metritis should be fattened ; cows that have 

 recovered should be disinfected before service ; sol. soda bicarb. 



VARIOLA OVINA. 



Sheep-pox. A contagious, inoculable, eruptive fever, probably depend- 

 ing upon a microbe. The incubation stage four to seven days. 

 Papules appear, passing into vesicles and pustules. The mortality 

 ranges from 10 to 20 per cent., but is greater in the confluent 

 malignant form occasionally occurring. Animals attacked are sub- 

 sequently immune. Goats, swine, and dogs have been infected. 



Infected and in-contact subjects should be slaughtered, and the 

 measures adopted in other contagious diseases rigorously carried out. 



As the disease runs a definite course, treatment consists in good 

 nursing and guarding against complications. 



Inoculation of healthy sheep with attenuated virus is not desirable, 

 for the attack produced is distinctly contagious, rather severe, and 

 the mortality averages 2 per cent. 



Variola vaccina, or cow-pox, results from accidental retro-vaccination 

 from recently vaccinated human patients, and similar eruptions 

 in like manner occur in swine and occasionally in dogs. 



A variola equina may be similarly produced, but the conditions 

 described as horse-pox are not variolous, and appear to be pustular 

 stomatitis and eruptions on the genital mucous membrane (Frohner, 

 Trasbot).
