BACILLUS MALIGNI CEDEMATIS 135 



Localized edema at the point of inoculation, grave septicemia, convulsions 

 and death are observed in all animals subject to infection. 



Diagnosis. The bacillus of malignant edema is easily recognized by in- 

 jecting a small amount of fluid suspected of containing the organism into a 

 guinea-pig, subcutaneously, noting the effect and making microscopic and 

 cultural examinations of bacteria found in the blood or cedematous area when 

 the pig dies.
