Microbic Diseases Individually Considered. 145 



PART THIRD. 



MICROBIC DISEASES INDIVIDUALLY CONSID- 

 ERED. 



I. 



Microbic diseases consecutive to wounds. 



Surgical wounds, treated strictly according to anti- 

 septic rules, are protected from pathogenic germs; 

 they heal without excessive swelling and without 

 suppuration or fever. The healing process is limited 

 to the extent of cell proliferation necessary for repa- 

 ration only. It is the same with accidental wounds 

 when they are rendered aseptic; but if, by the con- 

 tact or the subsequent action of the object causing 

 the injury, or by contact with clothing of any kind, 

 harness, litter, water, or the atmosphere, pathogenic 

 germs are introduced into the wound, diverse patho- 

 logical changes may be observed. 



"We have seen, in the general part of this work, 

 that a number of pathogenic germs, for example, 

 those of suppuration and septicaemias are encountered 

 almost everywhere ; we meet with them also in most 

 of the morbid conditions which complicate wounds ; 

 these diseases we shall iirst of all consider. 



The lesions of a microbic nature which develop 

 consecutive to wounds are local, remote, or general.
