Control and Eradication of Rabies. 
This most terrible disease is the most easily eradicated of all con¬ 
tagious diseases as shown by the results in England, where rabies once 
prevalent, is now practically unknown. As the spread of the disease 
is by the bite of a dog in practically every instance, the muzzling of 
all dogs with the destruction of those not kept muzzled, is the easy 
solution of the problem. This muzzling must be universal throughout 
the infected district. 
Pasteur Treatment. 
Soon after Pasteur had perfected the vaccine for Anthrax, which 
was about 1880, his attention was called to a little girl in a ward of 
a hospital dying of rabies. As a result of the study that followed, Pas¬ 
teur by experimenting on the lower animals perfected the vaccination 
method which is still used to vaccinate and protect the lives of people 
when bitten by a rabid dog. As early as 1880 it was a recognized fact 
that drying practically destroyed the virus of rabies. Pasteur took 
advantage of this fact by drying the cord of rabbits dead of rabies, 
over potassium hydrate thus attenuating it, and making a vaccine. By 
injecting a certain portion of the cord, so treated for 14 days, under the 
skin, in the form of an emulsion, followed once a day with a like in¬ 
jection, gradually using cord less attenuated, in 21 days the person is 
immune from the disease and the treatment is complete. 
Danger of Milk and Meat. 
In regard to the infectiousness of milk from rabid animals it 
must be considered at all times dangerous, as some experiments have 
proven that the milk is infectious. Some experiments conducted along 
this line have given entirely negative results. The young should be ta¬ 
ken away from the mother as soon as rabies is found to have developed. 
The milk should never be used for human consumption. So far, all at¬ 
tempts to produce rabies in experimental animals by feeding them the 
meat of animals dead of rabies have failed. The virus from the brain 
mixed with food has in some instances produced rabies experimentally. 
Rabies has been produced in mice by feeding them rabic brain mixed 
with their food.
