Hence, selective media contain antimicrobials, dyes, alcohols, etc. Compare the Difference Between Similar Terms. Available here. So, media could be both selective as well as differential. Web. Selective media allow the growth of a specific type of microorganisms and inhibit the rest of the other microorganisms. Recognizing the limits of currently used selective and differential media, it is desirable to develop a medium that can perform well in supporting the recovery … Differential media, unlike selective media, does not kill organisms. in Molecular and Applied Microbiology, and PhD in Applied Microbiology. “E.coli-fields” By Carmen Moreno González – Own work (CC BY-SA 4.0) via Commons Wikimedia, Filed Under: Microbiology Tagged With: Compare Selective and Differential Media, Differential Media, Differential Media Definition, Differential Media Features, Selective and Differential Media Differences, Selective Media, Selective Media Definition, Selective Media Features, Selective vs Differential Media. 51490: Hektoen Enteric Agar for microbiology, NutriSelect ™ Plus : Hektoen enteric agar is a type of primary standard media, which may be commonly used in the selective detection and isolation of Salmonella in food microbiology labs and in human stool specimens. They are formulated to isolate and identify a particular type of microorganism. It indicates only if the target microorganism is present in the medium by showing a different growth pattern or visible change. There are different types of media available for the culturing purpose. 4. Selective media and differential media are two types of growth media. A variety of selective and differential media are used in various types of microbiology laboratories. It is a modification of the classic medium, where neutral red is replaced by a less aggressive indicator, according European Pharmacopoeia. Certain media work as both selective and differential media. 1. The advantage of using selective media is the ability to control what will and will not grow on a particular culture plate or petri dish. Biochemical Tests for Staphylococcus Organisms. c) Selective media. Nutrient media: These media are also called general purpose media. You will need to look up the individual test for a more detailed description, including the biochemical basis of each test. YM (yeast extract, malt extract agar) has a low pH, deterring bacterial growth. Difference Between Selective and Differential Media. TOT Zoo Add Page Insert Table Chart Text Shape Media Comment These questions will serve in lieu of a lab report for Exercise 15, 16, and 17 You will find the answer to these questions in the background, procedure, results and interpretation sections of manual Exercise 15, 16, and 17, videos, Actions of Selective and Differential Media Chart, and the Principle/Theory article in homework section.) b) Enrichment media. Selective and Differential Media Varisce Alston March 28,2012 Dr. Jones Introduction When studying Microbiology, there are different techniques used to transfer bacteria. Unlike selective media, differential media are not included with the chemical which suppresses or inhibits other microorganisms. Eosin methylene blue selects for Gram-negative organisms. This is the difference between selective media and differential media. Blood agar medium is, however, differential. Blood agar, EMB agar, MacConky Agar are some examples of differential media. Wikimedia Foundation, 28 Apr. EMB agar, Mannitol Salt agar, MacConkey agar, and Phenylethyl Alcohol (PEA) are examples of selective media. 2. The selectivity is accomplished in several ways. Selective media = Media providing a means of isolating a particular species or type or microorganisms, while inhibiting the growth of others (e.g., EMB, MAC, T-7, MSA, etc.). Many different types of media are used to culture microorganisms. Selective and differential media is extremely useful when examining mixed bacterial cultures since it provides: a simple way to "screen out" certain bacterial species some biochemical information on the organisms present in the culture (presumptive identification) Media can be Selective and Differential Start studying MCRO Media Chart. The difference between selective and differential media is mainly due to the following factors: Intended use of the media: The purpose of both selective and differential media differs.A selective media only permits the development of particular organisms, while a differential media discerns one species of the organism from the other growing on the similar substrate. Differential media contain nutrients which are utilized differently by microbes and generally do not contain inhibitors to suppress other microbes. Blood agar, EMB agar, and MacConky agar are examples of differential media. Blood Agar (BAP) is another type of differential medium. Dr.Samanthi Udayangani holds a B.Sc. Selective media are used to isolate a particular type of microorganism by giving a specific condition for the growth of that particular microorganism. Key Terms. Differential media are designed to differentiate microorganisms from one another. Non selective media for primary isolation (Blood Agar) Selective or differential agar (e.g. Figure 01: Methicillin-resistant Staphylococcus aureus selective medium. Media: Mannitol Salt Agar, MacCokey Agar, Eosin-Methylene Blue Agar, and Blood Agar. Predict what you would see if you inoculated that same unknown onto the … Culture media are used to grow, isolate, differentiate and identify microorganisms. Selective and differential media are two types of growth media used to isolate and identify microorganisms. 2. Selective, Differential, & Enriched Media Lab Chart - Free download as Word Doc (.doc), PDF File (.pdf), Text File (.txt) or read online for free. “MRSA on a selective choromogenic media plate” By Xishan01 – Own work (CC BY-SA 3.0) Commons Wikipedia 06 June 2017. Examples of selective media include: Eosin methylene blue contains dyes that are toxic for Gram-positive bacteria. Terms of Use and Privacy Policy: Legal. Summary. For example, organisms that can utilize a … BAP is rich in nutrients and contains sheep blood. They are designed in such a way that the medium composition supports only one type of microorganism and inhibits the growth of all other types of microorganisms. Different types of selective media are available. It is the selective and differential medium for coliforms. Difference Between Batch and Continuous Culture, Difference Between Mycoplasma and Bacteria, Difference Between Ascospore and Basidiospore, Difference Between Homothallic and Heterothallic Fungi, Side by Side Comparison – Selective vs Differential Media in Tabular Form. 06 June 2017. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Examples of enriched media include sheep blood agar and chocolate (heated blood) agar. Examples of selective media … Contains 7.5 % NaCl (salt) which inhibits the growth of most microorganisms, except Staphylococcus species. Let us say that the specimen of interest is one cell in a million.
