Gand Bruxelles, 3, 1892. 

 B. Breslaviensis Kruse: Fliigge, Die Mikroorganismen, 1896, 377. 



Morphology. Bacilli 0.6-1.5 /u, long, slender ; 4-12 long flagella. 



Gelatin colonies. Like B. coli. 



Bouillon. Turbid, with a delicate membrane. 



Potato. Growth yellowish, abundant. 



Saccharose bouillon. Only a slight amount of gas. 



Pathogenesis . The feeding and inoculation of mice and rabbits cause enteric 



symptoms ; bacilli in the organs. 

 Habitat. Isolated from poisonous beef and veal which were the cause of 



meat poisoning.

 B. suipesti/er Kruse: Fliigge, Die Mikroorganismen, 1896, 223. 

 Bact. cholera-suum Lehmann-Neumann : Bak. Diag., 1896, 233. 



Morphology. Bacilli 0.6:1.2-1.5^. No characteristic polar stain. The 



central part of the rod frequently less stained than the periphery (Smith). 



According to Karliriski, bacilli 0.6-0.8: 1.2-2.0 /u., or longer rods; with 



alkaline methylene blue a polar stain. Flagella delicate, 3-4 times the 



length of the rod, peritrichic. 

 Gelatin colonies. Deep: round to oval, brown, homogeneous, or centre 



somewhat darker. Surface: colon-like, round, flat, irregular, grayish. 

 Gelatin stab. 'In depth, growth dense, gray, white, beaded; surface growth 



flat, rather small, white. 

 Agar slant. Growth grayish white, translucent to opaque, moist, glistening, 



and slimy. 

 Bouillon. A moderate or good growth, with much white sediment. Reaction 



not altered (Karlinski). 

 Potato (alkaline). Growth straw-yellow to light brown, usually abundant. 



On acid potato the growth is scanty and white (Karliriski).
