ORIGINAL ARTICLES. 
HOG CHOLERA. 
By D. E. Salmon, D.Y.M., Chief of the Bureau of Animal Industry. 
(A Paper read before the United States Veterinary Medical Association.) 
Until very recently the literature of hog diseases was very 
confusing, and not less so in Europe than in America. In the 
period from 1880 to 1885 the French came to regard all epizootic 
swine diseases as rouget. The Germans at the same time were 
directing their attention almost entirely to an identical disease in 
their country which they described under the name of rothlavf. 
Each of these words is synonymous with our erysipelas and was 
evidently used to designate this disease because of the predomin¬ 
ance of the skin lesions. In this country the prevailing hog dis¬ 
eases have been referred to under the name of “hog cholera,” a 
term which also indicates the chief organs affected, which with this 
disease are those composing the intestinal tract. 
Early in 1886 I published a series of articles in which I de¬ 
monstrated that hog cholera was a distinct and very different dis¬ 
ease from rouget and rothlauf. This opinion was based not only 
upon the symptoms and course of the disease, but upon the lesions 
found upon post-mortem examination and the microbe associated 
with them. This microbe was discovered in the laboratory of the 
Bureau of Animal Industry in 1885. 
About the time these articles were written Schulz described a 
disease in Germany under the name of scliweineseucke , which diff¬ 
ered from both rothlauf and hog cholera. It was a contagious 
disease and the prominent lesions were found in the lungs. Klein 
had previously described (1881) under the name of pneumo-en-
