SYSTEMATIC AND DESCRIPTIVE. 2O5 



Streptococcus of foot and mouth disease, 



(Microccccus of foot and mouth disease, Klein). Cocci 

 singly, in dumb-bells, and in curved chains. They 

 grow well in milk, in alkaline peptone- broth, in 

 nutrient gelatine, and in nutrient agar-agar. 

 Cultivated on obliquely solidified nutrient gelatine 

 they form a film composed of minute granules or 

 droplets closely placed side by side, but not con- 

 fluent. The gelatine is not liquefied. Observed 

 in the vesicles of sheep suffering from foot and 

 mouth disease. 



Streptococcus of septicaemia consecutive 

 to anthrax, Charvin. In rabbits, some hours after 

 death from anthrax, cocci in chains have been 

 found in the kidney and elsewhere. Inoculated 

 into rabbits fatal septicaemia was produced without 

 the presence of suppuration. 



Streptococcus septicus, Nicolaier Cocci, 

 diplococci, and chains. They grow very slowly in 

 nutrient media, forming in plate-cultivations after 

 several days minute dot-like colonies. In mice 

 they produce paralysis of the hind extremities and 

 death, and in rabbits a local inflammation and 

 death after two or three days. Isolated from earth. 



Streptococcus of Progressive Tissue Ne- 

 crosis in Mice.* Cocci '5 p in diam., in chains 

 or rosaries, and zoogloea ; their invasion causes 

 tissue necrosis with destruction even of cartilage
