264 BACTERIOLOGY 



Agar slant. Warty drops, becoming thick, yellowish white, with a green 



fluorescence. 



Potato. Growth slimy, light yellow, becoming dark brown. 

 Pathogenesis. Subcutaneous and intraperitoneal inoculations of mice cause 



death in 3 days to 2 weeks ; fatty degeneration of liver and kidneys, spleen 



enlarged, intestines hemorrhagic, with bacilli in the organs. 

 Habitat. Isolated from persons in icterus with nephritis ; from urinary 



sediment, etc. 



158. B. Ellingtonii 



B. No. 21 Conn : I.e., 1893, 52. 



Morphology. Bacilli 0.8 : 2.0 /u, chains. Grow at 35. 



Gelatin colonies. Small, opaque, liquefied quickly, becoming large, greenish, 



granular, with a central granular nucleus. 

 Gelatin stab. Liquefaction crateriform, becoming a broad funnel ; a pellicle 



on the surface ; gelatin clear, green. 

 Agar slant. Growth thin, white, transparent, slightly spreading; medium 



becomes greenish. 



Potato. Growth thin, moist, brownish. 

 Milk. Coagulated, alkaline, slowly peptonized. 

 Bouillon. Turbid, a slight pellicle, medium slightly greenish, later a tenacious 



pellicle on the surface.

159. B. leucaemias Lucet 



B. leuccemia-canis Lucet : Baumgarten's Jahresberichte, 1891, 319. 



Morphology. Bacilli slender, 3.0 p long. 



Gelatin stab. From the line of stab, lateral outgrowths ; a liquefaction and 

 fluorescence of the surface growth. 



Potato. Growth abundant, floccose curled. 



Pathogenesis. Inoculations of rabbits cause death in 10 days, with nodu- 

 lar formation on the inner organs, containing bacilli. Guinea pigs 

 immune. 



Habitat. Isolated from a dog with leukocythemia.
