B.viridis Kruse : Fliigge, Die Mikroorganismen, 1896. 



Morphology. Bacilli 0.7: 1.0-2.4 P\ filaments. Optimum temperature 35. 



Gelatin colonies. Thin, spreading, erose, with green fluorescence. 



Gelatin stab. Grow only on the surface. 



Potato. Growth dark green, rarely reddish, with odor of old urine. 



Pathogenesis. Intravenous inoculations and feeding of rabbits produces 



" green diarrhoea. 1 ' 

 Habitat. Associated with " green diarrhoea " of children.

Morphology. Bacilli as characterized, somewhat bent. Optimum tempera- 

 ture 37; scanty or slow growth at 20. 



Gelatin stab. Liquefaction occurs along line of stab; on the surface, a 

 greenish fluorescence. 



Agar colonies. Irregular, fluorescent. 



Agar slant. Growth dirty yellow. 



Potato. Growth chocolate-brown. 



Habitat. Isolated from nasal secretions in ozsena. 



157. B. urinae

Morphology. Bacilli variable, cocci filaments, variable also in thickness. 

 Gelatin colonies. Proteus coli-like, with a green fluorescence. Cultures 



stink as in proteus. 

 Gelatin stab. Gas often produced.
