THE CLASSIFICATION OF BACTERIA 303 



265. B. cuneatus 



B. Anaerobic No. Ill Fliigge : Zeitsch. f. Hygiene, XVII, 1894, 2 72- 



See No. 255. 



266. B. Lubinskii Kruse 



Ein tetanus ahnlicher obligat-ana'erober Bacillus Lubinski : Centralblatt f. Bakteriol., 



XVI, 1894, 771- 

 B. Lubinskii Kruse : Fliigge, Die Mikroorganismen, 1896, 267. 



Morphology. Bacilli like B. tetani. Stain by Gram's method. 



Gelatin colonies. Flat, grayish, radiately crumpled on edges. 



Gelatin stab. Growth arborescent. 



Agar stab. Much gas. 



Pathogenesis. Subcutaneous and intraperitoneal injections of rabbits cause 



death in 24 hours. There is a necrosis of tissue, a serous exudate, and 



much gas at the seat of inoculation. 

 Habitat. Isolated from an abscess. 



267. B. longus 



B. muscoides-colorabilis Liborius : Ucke, Centralblatt f. Bakteriol., XXIII, 1898, 1001. 



Morphology. Bacilli 1.8-2.0:4-12 /u, filaments. Polar oval spores, of the 



tetanus type. Slightly motile. Not stained by Gram's method. 

 Gelatin colonies. Small, white, punctiform ; grow slowly. 

 Bouillon. Turbid, with a heavy, white sediment. 



Agar slant. Growth bluish white, scarcely visible, with finely erose edges. 

 Agar stab. In depth, beaded, white colonies, gas. 

 Glucose agar stab. Abundant gas. 

 Milk. Not coagulated. 



Potato. Growth scarcely visible or very scanty ; no odor. 

 Litmus media. A reduction, with sugar, acid. 

 Pathogenesis. Non-pathogenic to guinea pigs. 

 Habitat. Isolated from garden earth. 



268. B. pseudotetanicus var. aerobius Kruse 



Fliigge, Die Mikroorganismen, 1896, 267. 



Morphological and cultural characters like B. tetani. Will grow at ordinary 

 temperatures with access of air, at higher temperatures only with the 

 exclusion of air. 



Habitat. Isolated from a case of tetanus.
