THE BACILLUS AND SPIRILLUM OF VINCENT 93 



fail to disclose diphtheria bacilli, while after incubation the cultures do reveal 

 them. 



If the condition be Vincent's angina, slides will always show fusiform bacilli 

 and spiralla; aerobic cultures never do. 



If, as sometimes occurs, a double infection exists, both Vincent's angina and 

 diphtheria, it is well to recognize it, as such a condition is said to be more grave 

 than diphtheria alone. 



Some authorities state that slides made from mild cases of Vincent's angina 

 show relatively smaller numbers than slides from severe cases. Usually the 

 organisms are quite numerous. As a rule, several or more organisms other than 

 the spirillum and bacillus of Vincent are found in slides made from cases of 

 Vincent's angina staphylococci and streptococci most frequently. At times 

 the spirillum and bacillus of Vincent are found in practically pure culture.
