PYOGENIC ORGANISMS 



A VERY large number of organisms possess, amongst 

 other properties, a pyogenic power ; and there are 

 not a few with whom this pyogenic function seems 

 to be the principal one. Amongst these latter, 

 however, there are three which, from the frequency 

 with which they occur in localised collections of pus, 

 in spreading purulent inflammation, and in pyaemia 

 and septicaemia, are of much greater importance 

 than the rest. These three microbes are : Strepto- 

 coccus Pyogenes, Staphylococcus Pyogenes Aureus, 

 and Staphylococcus Pyogenes Albus.
