THE CLASSIFICATION OF BACTERIA 219 



37. B. Friedbergensis Kruse 



B. der Friedberger Fleickvergiftung Gaffky-Paak : Mitteilungen a. d. Kaiserl. Gesund- 



heitsamte, 1890, 159. 

 B. Frudbergensis Kruse: Flugge, Die Mikroorganismen, 1896, 378. 



Morphology. Bacilli about one-third smaller than B. typhosus. 



Gelatin colonies. Deep: round, yellowish, homogeneous, often concentric. 



Surface : round, spreading ; centre yellowish, border paler, marmorated ; 



between aerogenes and colon types. 

 Gelatin stab. Good growth in depth ; surface growth thin, spreading to the 



walls. 

 Agar slant. Growth grayish white, slimy. 

 Potato. Growth whitish to grayish yellow to reddish. 

 Pathogenesis. Pathogenic to mice, guinea pigs, and rabbits, by subcutaneous 



inoculation. Pathogenic to guinea pigs and mice by feeding ; slightly so 



to dogs, cats, and rabbits. 

 Habitat. Isolated from poisonous sausage, in meat poisoning. 



38. B. phasiani Kruse 



Bacillus of an infectious disease of young pheasants Klein : Jour, of Path, and Bac- 



teriol., 1893. 

 B.phasiani-septicus Kruse: Flugge, Die Mikroorganismen, 1896, 410. 



Morphology . Bacilli like B. coli, but smaller. Cultural characters like those 



of B. coli. 

 Pathogenesis. Inoculation of pheasants causes death in 24 hours of general 



septicaemia ; fowls, pigeons, guinea pigs, and rabbits refractory. 

 Habitat. Associated with the above disease. 



39. B. Schafferi v. Freudenreich 



Ann. Micrographie, III, 1891. 



Morphology. Bacilli 1 .0 : 2-3 ft ; threads. 



Gelatin colonies. Deep: small, round, yellowish, granular. Surface: white 



(porcelain), spreading, slightly irregular. 

 Agar slant. Growth grayish to brownish. 

 Potato. Growth yellowish. 

 Habitat. Milk, cheese.
