HEMORRHAGIC SKT'I 1< KIWIA. 9 



In the October, 1916, issue of the American Sheep Breeder, Dr. 

 W. H. Lytle, Oregon State Veterinarian, reports very satisfactory 

 results from vaccination with an attenuated or weakened culture of 

 the living organism. About 3,000 sheep were treated with the ma- 

 terial. After 48 hours subsequent to the vaccination of the flocks 

 only nine sheep were lost, although previous to inoculation several 

 animals died each day. Bacterins made from the killed organism- of 

 hemorrhagic septicemia have been used also with considerable success 

 in Oregon bands of sheep. 



TREATMENT. 



In most cases treatment of a fully established case of hemorrhagic 

 septicemia in an animal of any species is quite useless. All appar- 

 ently well animals should be removed from those that are sick by 

 placing them in separate, noninfected quarters. If new cases de- 

 velop among them in a few days after their removal, the healthy 

 ones remaining should be removed again to another locality. In 

 that way the unaffected animals soon will be out of danger of further 

 contamination, especially if their strength has been supported by an 

 abundance of good feed and water during the period of their separa- 

 tion. 



DISINFECTION OF PREMISES. 



Premises usually become infected with hemorrhagic septicemia 

 by stock cattle that have recently passed through some of the larger 

 cattle' markets. Owing to this method of infection the stables and 

 yards may not be so completely contaminated as they would be if 

 the disease had developed spontaneously. In any event, all stables, 

 sheds, or yards that have contained infected animals should be dis- 

 infected. The interior of the stables, especially the mangers and 

 manure trenches, should be washed with a disinfectant, such as liquor 

 cresolis compositus (U. S. P.) or carbolic acid, 6 ounces to a gallon 

 of water in either case. The yards may be disinfected by the appli- 

 cation of a solution made of 5 ounces of copper sulphate to a gallon 

 of water. The best means of applying disinfecting solutions is 

 afforded by the use of a spray pump such as is used in the spraying 

 of orchard trees. All refuse and material from the stable and barn- 

 yard should be removed to a place not accessible to cattle, sheep, or 

 hogs. The manure should be spread on fields and plowed under. 

 A plentiful supply of light and air should be provided for the con- 

 taminated stables. Open fields or pasture lands are cleansed rapidly 

 by the action of sunlight upon them.
