Investigations Into the Etiology of Traumatic Infective Diseases

Koch's epochal work (1878) on the aetiology of traumatic infectious disease established his reputation. He inoculated animals with material from various sources and produced six types of infection, each due to microorganisms. He carried these infections through several generations of animals. His great work determined the role of bacteria in the aetiology of wound infections and demonstrated for the first time the specificity of infection. -- H.W. Orr.
