of the body is termed pyemia. Pyemia is, therefore, 

 only a form of septicemia. 



Mixed Infection. In any pus infection we are apt to 

 have a mixed infection, with several pyogenic germs, 

 rather than a pure culture of any one germ, one germ 

 seeming to pave the way or prepare the field for the 

 growth of another. Thus the staphylococcus and strep- 

 tococcus are frequently found in the same pus foci, 

 while the lesions of tuberculosis and of pneumonia are 

 frequently infected with pus cocci.
