VERANUS A. MOORE, B.S., M.D. 
highly important that the nature of the maladies in question 
should be clearly understood, for among animal diseases there 
are none which are more analogous to certain human affections 
than these bacterial plagues of swine. If the suggestion that 
this subject should be opened for discussion was correctly in¬ 
terpreted it was for the purpose of having some of the essential 
features of these diseases, as they have been determined by Ameri¬ 
can investigators, again pointed out that their differences and 
their independent existence could be more fully appreciated. 
As I understand the situation all elements of confusion will be 
removed if the following questions can be clearly and fully 
answered : 
1. Concerning the nomenclature of infectious swine diseases 
in Europe and America. Which of the names given to the dis¬ 
eases of swine are synonyms of hog cholera, which of swine 
plague, and which represent other affections ? 
2. Concerning their morbid anatomy. What are the lesions 
characteristic of hog cholera and what are those diagnostic of 
swine plague ? 
3. Concerning their etiology. What are the morphological 
characters, biochemic and pathogenic properties by which the 
hog-cholera and swine-plague bacteria can be differentiated ? 
In a paper of this length it is impossible to answer these 
questions in detail, but it is hoped that some of the essential 
truths may be pointed out and that references * may be given 
to such papers and reports that any who may desire, can find 
the entire story, as it is known at the present time, in our most 
authoritative publications. 
In the United States of America two infectious diseases pe¬ 
culiar to swine have been described under the names of hog 
cholera and swine plague. The third malady—swine erysipe- 
* In citing the literature, reference is made simply to the more important papers giv¬ 
ing the results of original investigations which have been made in this country. The 
criticisms, controversial writings and more popular articles must, for want of space, be 
omitted. An abstract of nearly all the papers relating to these diseases may be found in 
the Jahresbericht iiber die Leistungen auf dem Gebiete Veterinar-Medicin, and al.so in 
Baumgarten’s Jahresbericht, 1885-1896.
