 skin lasting for a few days without producing the disease. 



Organism No. 3. A small non-motile cocco-bacillus. 



Gram positive. 

 Gelatin and blood serum: not digested. 

 No action on normal or litmus milk. 

 Dextrose and sucrose broth: acid and no gas. 

 Lactose: no change. 

 Does not produce agglutination or complement fixation. 



Pathogenicity: Does not produce the disease. 



Organism No. 4. A large motile square-ended bacillus 



resembling B. agiles. Gram negative. 

 Broth: membranous scum. 

 Gelatin: arborescent growth and digestion. 

 Agar: abundant, spreading moist growth. 

 Milk: coagulated and digested with slight acid production. 

 Blood serum: not digested. 

 Sugar-broth: no change. 



Pathogenicity: produces lesions but no general symptoms. 

 Organism No. 5. Pseudomonas pyocyanea. 



Pathogenicity: Swelling and inflammation at point of injec- 

 tion. Intravenous injection resulted in septicemia recovering 

 the organism from heart, kidneys, etc. 



Organism No. 6. A small slender, highly motile bacillus. 



Gram negative.
