By comparing these capabilities, one can group and identify the organisms being studied. The MacConkey’s and Mannitol Salt described above are both selective and differential bacterial growth media. Blood Agar (BAP) is another type of differential medium. Selective media is supplemented with antibiotic sensitive to the target organism resistant for the growth of other organisms. While the plate on the right selectively only allows the bacteria Neisseria gonorrhoeae, to grow (white dots). I have been a nurse since 1997. Selective media• culture medium that allows the growth of certain types of organisms, while inhibiting the growth of other organisms• Any agar media can be made selective by addition of certain inhibitory agents that don’t affect the pathogen.• Add to Cart. These are the Differential & Selective Bacterial Growth Media Lecture materials of the Virtual Microbiology Classroom.The resources below are used to … Synonym. Selective medium is agar based (solid) medium so that individual colonies may be isolated. In addition to MacConkey’s agar only growing Gram-negative bacteria (the selective aspect of the medium), MAC has special additives that cause lactose fermenting bacteria (microbes that can Microorganisms are metabolically quite diverse. Differential media typically display some type color change in the presence of certain bacteria. For example, if a microorganism is resistant to a certain antibiotic, such as ampicillin or tetracycline, then that antibiotic can be added to the medium in order to prevent other cells, which do not possess the resistance, from growing. A selective media. Examples of selective media include: Thayer Martin Agar used to recover N. gonorrhoeae contains antibiotics; vancomycin, colistin and nystatin. differential & selective media lab documents The Lab Project Instructions provide a thorough explanation of the lab topic, as well as detailed directions on how to complete the lab exercise. All the best. These media are designed to inhibit unwanted commensal or contaminating bacteria and help to recover pathogens from a mixture of bacteria. The selectivity is accomplished in several ways.
