THE CLASSIFICATION OF BACTERIA 265 



b. Much larger rods to coccoid forms, variable. 



157. B. urines. 



158. B. Ellinglonii. 

 II. Gelatin liquefied quickly. 



A. Gelatin stab cultures arborescent; potato cultures floccose — curled. 



159. B. lucamia Lucet. 



B. Cultures on gelatin and potato not characterized as above. 

 I . Cultures have a decided aromatic odor. 



160. B. helvolus. 



155. B. Lesagei Trev. 



Bn de la diarrhee verte des enfants Lesage : Bull. Acad. Med., Paris, October, 1887. 



B. Lesagei Trevisan : Genera, 1889, 14. 



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



Morphology. Bacilli 0.7 : i .0-2.4 ;t ! 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." 

 Habitat. Associated with " green diarrhoea " of children. 



156. B. smaragdinus Reiraann 



B. smaragdino-fcetidus Reimann : Phil. Diss., Wurzburg, 1887. 



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 ozaena. 



157. B. urinae 



B.proleus-Jluorescens Jager: Zeitsch. f. Hygiene, XII, 1892, 525- 



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.
