HISTORICAL REVIEW 25 



The great German scientist, Koch, extended and developed the 

 work of Pasteur. His solid media and bacterial stains made the 

 growth, indentification and separation of bacteria comparatively easy. 

 His untiring labor led to the discovery of the specific bacteria of 

 Asiatic cholera and tuberculosis, and has placed in man's hands the 

 possibility of completely eradicating these and other infectious diseases. 



The work so firmly established by Pasteur and Koch has been 

 amplified by many workers in many lands and has led already to 

 marked reduction in both morbidity and mortality from the infectious 

 diseases. Much has been accomplished in the attempt to lift the 

 burden of unnecessary disease from man, but greater tasks lie 

 before us. 



This article will be limited to the bacterial diseases and only the 

 more common of these can be included.
