136 ESSENTIALS OF BACTERIOLOGY. 



Bacteria of Hemorrhagic Septicaemia. (Hueppe.) 



Under this heading Hueppe has gathered a number of bac- 

 teria very similar to the bacillus of chicken cholera, differing 

 from it and each other but very little. They have been described 

 by various observers and found in different diseases. 



1st. Bacillus of American Swine Plague. Syn. Hog cholera; 

 infectious pneumonia. (Billings, Detmers, and Salmon.) 



2d. Bacillus of Swedish-Danish Swine Plague. Swine </////<- 

 theria. (Selander. ) 



3d. Bacillus of Swine Plague. (Loffler, Scliutz.) 



4th. Bacillus of Texas Fever. Cattle plague. (Billings.) 



5th. Bacillus of the Steer Plague. (Oreste and Armanni.) 



6th. Bacillus of the French Swine Plague. (Coruil and 

 Chantemesse.) 



7th. Bacillus Cuniculicida. Rabbit septicaemia. (Gaffky.) 



8th. Bacillus of Duck Cholera. (Cornil and Toupet;) 



Differences. The various bacilli found in swine plague differ 

 from each other very slightly. 



They are but little active in/ourfs, very fatal in pigs and mice. 



In pigs, hemorrhages occur in all the viscera, the mucous mem- 

 brane of the intestines being ulcerated and necrosed. 



The cultures of the Swedish swine plague No. 2 of the above 

 list resemble the typhoid bacillus. The form and cultures of 

 the others are hardly to be distinguished from those of the 

 chicken cholera. 



The bacillus of duck cholera (No. 8) is harmless for chickens, 

 but fatal to ducks ; otherwise identical with chicken cholera. 



Bacillus of Rabbit Septicaemia. Similar in action to the 

 chicken cholera. 



The other properties are identical with those of the microbe 

 of chicken cholera. 



Bacillus of Erysipelas of Swine. (Loffler, Schiitz. ) Sch m ;, - 

 rollaufbacillus (German). Rouget du pore (French). 



Origin. Found in the spleen of an erysipelatous swine by 

 Loffler in 1885. 



Form. One of the smallest forms of bacilli known ; very thin, 

 seldom longer than 1 /*, looking at first like little needle-like 

 crystals. Spores have not been found.
