The Disc Technique for Determining Sensitivity to the Antibiotics

The range of antibiotics available for therapy is extending steadily, and in consequence there is an increasing demand on the services of the laboratory. Chloramphenicol has now been added to the free list, aureomycin is being used for certain prescribed conditions, and terramycin is generally available in the U.S.A. This form of therapy should be subjected to bacteriological control, and it is therefore important to have a simple and reliable method of determining sensitivity.
