THE CLASSIFICATION OF BACTERIA 145. 



60. Bact. nephritidis (Vassalle) 



B. hcemorrhagicus-nephritidis Vassalle : Tizzoni-Giovannini, Ziegler's Beitrage, VII, 1889. 



Morphology. Bacilli similar to those of fowl cholera, but less pathogenic to 

 rabbits ; strongly so for guinea pigs ; intraperitoneal inoculations cause 

 hemorrhagic nephritis. 



Habitat. Isolated from a case of hemorrhagic nephritis. 



61. Bact. aphthosum (Kruse) 



Bacillus der Mundseuche des Menschen (Stomatis epidemica) Siegel : Deutsche med. 



Wochensch., 1891, No. 49. 

 B. aphthosus Kruse : Fliigge, Die Mikroorganismen, 1896, 427. 



Morphology. Bacilli short 0.5-0.7 //, filaments ; show polar stain. 



Gelatin colonies. Small, entire, bluish white yellowish. 



Gelatin stab. Growth in depth, beaded. 



Pathogenesis . Non-pathogenic to rabbits, guinea pigs, mice, dogs, and cats. 



Local infection through the mouth to young pigs and calves. 

 Habitat. Isolated from the liver and kidneys of cattle affected with "Maul" 



and " Klauenseuche." 



6*. Bact. dysenteriae (Kruse) 



Bacillus der weissen Ruhr der Kdlber Jensen: Monatshefte f. prakt. Thierheilk., Ill, 



1892, 92. 

 B. dysenterice-vitulorum Kruse : Fliigge, Die Mikroorganismen, 1896, 412. 



Morphology. Bacilli somewhat larger than those of fowl cholera ; show polar 



stain. Cultures similar to those of B. colt. 

 Potato. Growth slimy, brownish. 

 Pathogenesis. The feeding of 5 cc. of bouillon culture to young calves gives 



a fatal diarrhoea, with bacilli in intestines and organs. 

 Habitat. Associated with dysentery of calves. 



63. Bact. salivae (Kruse) 



B. saliva-minutissimus Kruse : Fliigge, Die Mikroorganismen, 1896, 440. 



Morphology. Bacilli small like those of influenza. Decolorized by Gram's 



method. 



Gelatin stab. Surface growth flat. 

 Potato. Growth brownish. 



Habitat. Isolated from secretions of the mouth.
