The contributions to this book derived from the Seventh Munich Symposium on Microbiology on June 3 and 4, 1981, which was organized by the WHO Centre for Collection and Evaluation of Data on Comparative Virology at the Institute of Medical Microbiology, Infectious and Epidemic Diseases, University of Munich, Federal Repub- lic of Germany.
When discussing the drug, the bug, and the host in the past, emphasis was laid mainly upon the interaction between antibiotics and bacteria or the reaction of the host to the invading organism.

No one has counted the enzymes in the human organism, and probably their profuse number can only be estimated from the restrictions the finite mass of genetic material imposes.
During recent years enzyme histochemical reactions have increasingly been considered as important, the reason being that enzyme histo- chemistry is now a well-established link between morphology and bio- chemistry.
