A number of investigators have recovered from cases of 

 acute articular rheumatism organisms resembling the pyo- 

 genic cocci. Most frequently a diplococcus or short strepto- 

 coccus has been found, which has sometimes produced 

 arthritis and endocarditis when inoculated into rabbits.

 (X 1000.) 



From a point where there is suppuration or other local- 

 ized infection, pyogenic bacteria may enter the circulation 

 and become widely disseminated throughout the body. 

 That happens very commonly in malignant endocarditis. In 

 this manner secondary or metastatic abscesses may be pro- 

 duced in the most diverse organs. 



The term pyemia is used to describe the dissemination of 

 pyogenic bacteria in the circulating blood, with the forma- 

 tion of metastatic abscesses.
