HEMORRHAGIC SEPTICEMIA. 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 organisms 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. AI] 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 « 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.
