BACTERIA IN SURGERY. 
Germs 
Commonly- 
Encountered. 
CHAPTER VI. 
SEPSIS, ASEPSIS AND ANTISEPSIS. 
In surgical practice the bacteria met with most 
frequently are the following: 
The staphylococcus pyogenes aureus, the 
Streptococcus pyogenes, the bacilli coli com¬ 
munis, the bacillus tuberculosis and the bacil¬ 
lus tetani. 
The Staphylococcus *Pyogenes Aureus. 
Water, dust and air are all means by which this 
micro-organism is distributed. It is found, also, in 
the mouth, under the finger-nails, and in super¬ 
ficial layers of skin. This is the germ most fre¬ 
quently found to be concerned in severe forms of 
inflammation confined to small areas in which pus 
is found, described as “acute, suppurative circum¬ 
scribed inflammation.” While the staphylococcus 
pyogenes aureus does not form spores, it is very 
difficult to destroy, resisting to a remarkable de¬ 
gree all means used for its extermination. 
The Staphylococcus Pyogenes *Albus and 
*Citreus. These germs are found in the pus 
*Pyogenes signifies pus-forming. Aureus, golden-yel¬ 
low. 
Albus means white. 
Citreus, citron-yellow. These colors are assumed 
when seen in growing cultures.
