When the same approach is employed for liquid culture medium, it is called enrichment broth. View Selective and Differential Media fall 2018 (1).pptx from BIOLOGY MISC at Henderson State University. • MANNITOL SALT AGAR (MSA) • Mannitol salt agar (MSA) is both a selective and differential medium used in … Enrichment medium is used to increase the relative concentration of certain microorganisms in the culture prior to plating on solid selective medium. TYPES OF CULTURE MEDIA MANNITOL SALT AGAR (MSA) SELECTIVE MEDIA AND DIFFERENTIAL MEDIUM Dr Yousef Elshrek 2. • L.J IS A SOLID MEDIUM USED FOR MTB LOWEINSTON JENSON 22. Basal media are those that may be used for growth (culture) of bacteria that do not need enrichment of the media. Selective medium is designed to suppress the growth of some microorganisms while allowing the growth of others. Selective medium is agar based (solid) medium so that individual colonies may be isolated. described below and will be used in the laboratory exercise. Media classification and function Selective - Contain inhibitory agents that are inhibitory to all organisms except those sought Differential - Contain factors that allow bacterial species to manifest certain metabolic characteristics that distinguish them from other species. These are classified into six types: (1) Basal media, (2) Enriched media, (3) Selective media, (4) Indicator media, (5) Transport media, and (6) Storage media. b. Enrichment culture medium. Selective Differential Media - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. Three of the more common selective and differential media are . The selectivity is accomplished in several ways. Some media are both selective and differential, that is, they are able to select against the growth of certain organisms while the organisms that do grow may exhibit some differential growth characteristics. dgdrb Selective media such as TCBS Agar used for isolating V. cholerae from fecal specimens have elevated pH (8.5-8.6), which inhibits most other bacteria. PPT presentation of microbiology lab exercise teaching students about specialized differential and selective bacterial growth media: MacConkey's MAC, Mannitol Salt MSA and Blood Agar BAP. Selective marketing attempts to eliminate guesswork and waste in small business marketing and replace it with precisely targeted efforts. For example, organisms that can utilize a given sugar are easily screened by making that sugar the only carbon source in the medium. What Is Selective Marketing?. Examples of Selective media • Campylobacter Agar (CAMPY) is used for the selective isolation of Campylobacter jejuni subsp. jejuni from fecal or rectal swabs 21. Examples of selective media include: Thayer Martin Agar used to recover N. gonorrhoeae contains antibiotics; vancomycin, colistin and nystatin. SELECTIVE MEDIA Those culture media that permits the required bacterium to grow and selectively inhibit unwanted commensals and contaminants are termed selective media. Selective marketing can reduce the cost of your small-business marketing while increasing … The main difference between selective and differential media is that selective media are used to isolate a particular strain of microorganisms whereas differential media are used to identify and differentiate a closely-related group of microorganisms. On the other hand, Selective media allow certain types of organisms to grow, and inhibit the growth of other organisms. Examples: Types of culture media.pptx 2 1.
