BACTERIOLOGY 



Gelatin stab. In depth, growth beaded ; on the surface, a convex growth. 



Agar slant. Growth whitish yellow gray, soft, glistening, spreading. 



Bouillon. Turbid, with a slimy sediment. 



Milk. Not coagulated (according to some authors coagulated). 



Potato. Growth yellowish-grayish, slimy, glistening, thin, with gas bubbles. 

 Indol slight. H 2 S slight. Ethyl-alcohol, acetic, and formic acids pro- 

 duced (Frankland). 



Pathogenesis . Variable. Subcutaneous inoculation of mice causes death by 

 general septicaemia ; also in guinea pigs and rabbits, by intraperitoneal 

 and intravenous injections. 



Habitat. Found in normal saliva. Associated with bronchopneumonia^ 

 bronchitis, and various inflammatory and purulent conditions.

 tiate from Bact. pneumonia:.

 Bact. ozcence Lehmann-Neumann : Bact. Diagnostik, 1896, 204. 



Morphology. Bacilli of variable length. Capsule in the body, occasionally 

 in milk cultures. 



Gelatin colonies. Transparent, watery, viscid. 



Gelatin stab. Surface growth thin, spreading. 



sigar slant. Growth watery, with a tendency to run down into the condensa- 

 tion water. 



Milk. Not coagulated. 



Potato. Growth watery, with gas bubbles only sparingly. Indol negative. 

 Do not grow in acid gelatin. 



Pathogenesis. Subcutaneous inoculation of mice causes death in 1-4 days, of 

 septicaemia. Guinea pigs, subcutaneous inoculations negative ; intraperi- 

 toneal injections cause peritonitis, etc. Rabbits refractory. 



Habitat. Isolated from nasal mucus in coryza.
