 1 . Centralblatt f. Bakteriol., IX, 561. Phenol negative for buffelseuche , 

 both indol and phenol produced by the other varieties. 



36. Bact. pneumopecurium 



Bacillus of sporadic pneumonia of cattle Smith : U. S. Dept. Ag., 

 Bureau Animal Industry, 1895, 136. 



Morphology. Bacilli like those of swine plague, except the presence of a 

 capsule, 0.5-0.6: i.o /u,. Cultures become viscid with age. Growth on 

 gelatin slight or invisible. 



Agar colonies. Round, translucent, grayish, reaching 4 mm. in diameter. 



Agar slant. Growth grayish, glistening, fleshy ; water of condensation viscid. 



Potato. Growth not manifest. 



Milk. Unchanged. Phenol produced. Indol absent or doubtful. Generally 

 absent. No gas in glucose and saccharose bouillon. 



Bouillon. A slight sediment, viscid when old. 



Pathogenesis. Similar to the bacillus of swine plague. 



37. Bact. sanguinarium Moore 



U. S. Dept. Ag.. Bureau of Animal Industry, 1895, 189. 



Morphology. In the body, bacilli 1.0-1.3: 1.4-1.8 /x, or coccoid forms, ends 



rounded ; involution forms common. In cultures, longer and more 



slender forms occur. Decolorized by Gram's method. 

 Gelatin colonies. Deep: grayish yellow, granular, 0.25 mm. Surface- 



slightly spreading, granular, without markings. 

 Gelatin stab. Growth more abundant along the line of inoculation than on 



the surface. 



Agar slant. Growth at 37, grayish, glistening. 

 Potato. A delicate grayish, glistening growth ; often no development on 



acid potato. . 

 Alkaline bouillon. In 24 hours a uniform turbidity, acid, becoming clear, with 



a granular sediment. In acid bouillon only a slight growth. 

 Milk. In 4 weeks, no change ; in 6 weeks, medium, opalescent, alkaline, 



saponified.
