The first true antibiotic to be derived from a culture of an actinomyces was isolated in our department in 1940. The organism, Actinomyces antibioticus, yielded a substance which was designated as actinomycin. It was soon crystallized, and its chemical and biological properties were established.

It has been recognized since the dawn of microbiology that the soil is inhabited by a living microscopic population which is responsible for the numerous reactions that take place in the soil and that affect the life and economy of man in many ways.

In the development of antibiotics, the soil microbiological population has contributed more than its share. It is to the soil that the microbiologists came in search of new antibacterial agents.

The discovery of streptomycin as a product of a rather obscure group of microorganisms, the actinomycetes, led to the study of these organisms as potential producers of other chemotherapeutic substances.

With the exception of autotrophic bacteria, the green, or chlorophyll-bearing, plants are the only living forms on this planet capable of synthesizing organic matter out of inorganic elements and simple compounds.

The soil is not a mass of dead debris, merely resulting from the physical and chemical weathering of rocks; it is a more or less homogeneous system which has resulted from the decomposition of plant and animal remains. It is teeming with life.

Streptomycin belongs to a group of compounds, known as antibiotics, which are produced by microorganisms and which possess the property of inhibiting the growth and even of destroying other microorganisms.

In learning to utilize antibiotics for the control of human and animal diseases, the medical and veterinary professions have acquired powerful tools for combating infections and epidemics.
