Staphylococcus pyogenes aureus.- This organism 



also the Streptococcus pyogenes can be detected in 

 sections of the kidney, suprarenal body etc. in pyaemia 

 of man, or in the organs of rabbits inoculated with pure 

 Cultures. The sections should be stained by Gram's 

 method, or with carbolic fuchsine. 



Chicken cholera bacillus. This can best be de- 

 monstrated in sections of the liver, spleen and pectoral 

 muscles of a pigeon. Simple staining with carbolic fuch- 

 sine or anilin water gentian violet will give fair results. 



Micrococcus tetragenus. The kidneys, lungs etc. 

 of white mice and guinea-pigs give excellent preparations 

 when stained by Gram's method.
