132 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. HjS slight. Ethyl-alcohol, acetic, and formic acids pro- 

 duced (Frankland). 



Pathogenesis. Variable. Subcutaneous inoculation of mice causes death by 

 general septicsemia; 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. 



Varieties 



Probably varieties of the above : not sufficiently described to clearly differen- 

 tiate from Bact. pneumonia.

26. Bact. ozaense (Abel) Lehmann-Neumann 



Bacillus mucosus-ozcBficB Abel ; Zeitsch. f. Hygiene, XXI, 1896, 88, 

 Bact, ozmncs 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. 



^gar 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 ciuses 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.
