THE CLASSIFICATION OF BACTERIA 257- 



2. No pigment granules in the rods. 



142. B. prodigiosus (Ehrenberg) Fliigge. 



143. B.fuchsinus Bokhont-de Vries. 

 II. Pigment flesh-colored. 



144. B. carneus Kruse. 



139. B. piscatorus (Lehmann-Neumann) 



B. ruber-sardincs Du Bois Saint Sevrin : Ann. Pasteur Inst., 1894, 31. 

 Bad. piscatorum Lehmann-Neumann; Bak. Diag., 1896, 263. 



Morphology. Bacilli short rods, 0.5-0.6 /n, mostly in twos. Gelatin liquefied". 



with a strong membrane of a carmine-red color. Pigment production 



weaker in bouillon or on agar when grown at 37°. 

 Potato. Growth of a beautiful carmine-red color. Culture gives a strong. 



odor of trimethylamine. 

 Habitat. Isolated from sardine oil. 



140. B. indicus (Koch) Trev. 



M. indicus Koch : ref. indt. 



B. indicus-ruber Fliigge : Die Mikroorganismen, 1886. 



Bact. indicum Crooksliank : Manual, 1887, 240. 



B. indicus Trevisan : Genera, 1889, 17. 



Morphology. Bacilli small, very short. 



Gelatin colonies. Deep colonies golden yellow, erose. Surface colonies have 



incised, torn edges. 

 Gelatin stab. Liquefaction saccate ; on the surface a fragile, red membrane ; 



sediment white. 

 Agar slant sxiA potato. Growth brick-red. 

 Pathogenesis. Intravenous inoculations of large doses into rabbits cause 



death with toxaemia. 

 Habitat. Isolated from the stomach of aa.ape. 



141. B. rubus Kruse 



Dtr rather Bacillus Lustig: Diag. der Bak. des Wassers, 1893, 7a. 

 B. ruber-aquaiilis Kruse : Fliigge, Die Mikroorganismen, 1896, 303. 



Morphology. Bacilli small, 2-3 times their breadth, red pigment granules- 



within the rods. 

 Gelatin colonies. Erose, reddish, becoming liquefied.
