Norm says:
‘Clinical microbiologists use culture plates containing different types of agar based media to identify bacteria and fungi that cause infections in patients. Pathogenic microorganisms are isolated in the laboratory from clinical specimens on media containing ingredients such as antibiotics, special nutrients, or dyes. These ingredients often enable the organisms to grow better or display a characteristic appearance or colour that makes them more easily identified from other organisms. These types of test are done by the millions, annually, at large academic medical centers.’
