[Culture media for antibiotic sensitivity testing (author's transl)]

Abstract

The medium is undoubtedly one of the most important factors influencing the sensitivity testing techniques. The possible role of pH and different components of media, as such as the concentration of peptone, tymidine or tymine, riboflavin, cations (MG++, Ca++, Fe++), mineral salts, agar and phosphate (added eventually with buffer solutions) is discussed. The conclusions point to the need of synthetic media which are suitable for growing all common pathogens and to not interfere with the antibacterial activity of drugs.
