88 SWINE ERYSIPELAS 
pigs is not fully determined. It is clear, however, that such a condi- 
tion often occurs in the absence, so far as present knowledge goes, of a 
specific infection. It is frequently found in pigs suffering from diges- 
tive troubles, or poisoning from eating decomposed offal. 
Prevention. Swine infected with this disease readily transmit it to 
others. The organism is reported to remain for a considerable time 
in the pharynx and nostrils and also to have been found in healthy 
swine. It is stated also to exist in the soil in a saprophytic form. 
These facts render prevention difficult. The general precaution of 
removing the sick from the well and not placing healthy swine in 
infected yards for some months after the recovery or removal of sick 
ones should be observed. 
Pasteur’s preventive inoculation -was until recently the chief pro- 
phylactic means employed against epizodtic erysipelas. Metchnikoff 
found that the blood of immunized rabbits was antitoxic, and Lorenz 
maintains that the serum of swine that have recovered from swine 
erysipelas is also antitoxic, and will produce immunity in other ani- 
mals. The treatment introduced by Lorenz is to inject the immuniz- 
ing serum in the proportion of 1 cc. to every 10 kilograms of the body 
weight of the animal. Two days afterward 0.5 to 1.0 cc. of virulent 
culture is injected, and after twelve days the dose is doubled. The use 
of the immunizing serum is reported to be very successful. 
Specific biologic treatment. The serum prepared by Lorenz is 
reported to give excellent results in acute cases.
