ETIOLOGY OF THE GERMAN SWINE PLAGUE.

THE LATEST CONTRIBUTION TO 1 HE ETIOLOGY OF THE GER¬ 
MAN SWINE PLAGUE AND SIMILAR DISEASES. 
From an Article in the Berliner Klinische "Wostrenschrift, 1886, Nos. 44, 45, 46, 
Entitled “Ueber die Wildseuche und ilire Bedeutin fhr die National 
Ekonomie und Hygiene,” critically considered 
By Dr. Billings.* 
(Prepared especially for the American Veterinary Review .) 
Although we cannot by any means accept all of Dr. Hueppe’s 
conclusions as to the identity of the diseases which he groups to¬ 
gether under the name of u Septicoe mia hoemorrhagica ,” still his 
exhaustive communication upon the subject should not be over¬ 
looked, especially as it has such an important bearing upon the 
diseases of our domestic animals, those of swine in particular. 
Instead of simplifying matters this communication rather tends to 
increase their complexity and opens to American investigators 
several very important questions. By “ Wildseuche,” in the 
sense the word is used, is meant a disease attacking animals of the 
deer species; as we have no extensive deer parks in this country 
it will be a hard matter to decide that question here, or contribute 
anything new to it. As the same disease has also been shown to 
attack the domestic animals we have to decide, however— 
1st. Have we this disease among our domestic animals, and 
which ? 
2d. Is it identical with our “ hog cholera,” or better, that 
form of “ hog cholera ” which corresponds in its microscopic 
lesions, to Klein’s “ Pneummoeteritis,” which is the “Swine 
Plague ” of Delmers, Salmon and myself. 
3d. Is this American swine plague identical with Schutz’s 
“ Schweineseuche ?” (I consider it is at present.) 
As will be seen, Huppe claims that there is no essential differ¬ 
ence between the germs of Schutz’s “ Schweineseuche,” u hen- 
cholera ” and this “ Wildseuche,” either in their morphological or 
biological phenomena, which I do not think he has proven by any 
means. The readers of my communication (made through my 
♦This paper was prepared November last, and as will be seen, does not fully 
igree with my conclusions in my paper on the “Etiological Moment in Swine 
Plague,” published later.
