Bact. cholertt-gallinarum Crookshank : Manual Bacteriology, 1887, 232. 



Coccobacillus avicidus Gamalei : Centralblatt f. Bakteriol., IV, 1888, 161.

Gaffky, Mitteilungcn Kaiserl. Gesundheitsamte, I, 1881, 94. 

 B. cu/ticulicida Fliigge: Die Mikroorganismen, 1886. 



Morphology. Bacilli 0.4-0.6: 1.0 ft; show polar stain. 



Gelatin colonies. Surface colonies like B. coli. 



Agar slant. Aggregations of delicate colonies. 



Potato. Growth waxy, translucent, gray-white, flat. 



Bouillon. A slight turbidity. 



Milk. Coagulated, acid. 



Litmus milk reduced. Produce indol and phenol. 



Pathogenesis. Subcutaneous injections of small doses produce septicaemia in 



chickens, pigeons, geese, ducks, etc. ; also in rabbits and mice. 

 Habitat. Associated with chicken cholera, and septicaemia of rabbits. 



32. Bact. gallinarum (Kruse) 



Bacillus of infectious enteritis in fowls Klein : Centralblatt f. Bakteriol., V, 1889. 

 B. gallinarum Kruse: Fliigge, Die Mikroorganismen, 1896, 416. 



Morphology. Bacilli 2-3 times the length of fowl cholera. Cultural characters 



identical with the preceding. 

 Potato. 37 , no growth, later a brownish growth. Differs from the preceding 



mainly by its weaker pathogenic properties ; only chickens affected 



by subcutaneous injections and by feeding. Stools loose, death in 7-9 



days, with bacilli in the blood. 

 Habitat. Isolated from cases of enteritis in fowls. 

 Variety. Bacillus of dysentery in turkeys and fowls Lucet : Annales Pasteur 



Institut, 1 89 1, 5. Not differentiated from the preceding. 



33. Bact. anaerogenes (Lembke) 



B. coli-anaerogenes Lembke : Archiv f. Hygiene, XXVII, 1896, 384. 

 Morphology. Bacilli 1.0:2.0 ft. Morphology and cultural characters like 



B. coli. 

 Lactose bouillon. No gas; produces an amount of acid intermediate between 



B. typhi and B. coli.
