uestion 1 Growth of an organism on mannitol salt agar plates indicates that the organism ferments...
Scenario 1: A bacterium isolated from a wound sample gave the following results: MacConkey agar = no growth Mannitol salt agar - good growth, color of medium unchanged Based on these results, which of the following statements is/are true? (Choose ALL true statements.) A. The organism is most likely Gram positive. B. The organism is most likely Gram negative. C. The organism is most likely a bacillus. D. The organism is most likely a coccus. Which of the following most...
Microbiology - Gram Positive (ONLY answer) [Q1] Mannitol salt agar is both selective and differential. - True - False [Q2] Mueller Hinton medium is a selective and differential medium. - True - False [Q3] 6.5% Salt broth is used to distinguish - Streptococci and Enterococci - Streptococci and Staphylococci - E. coli and Salmonella - Enterobacter and Streptococci
Please answer all (1 pt 27) The two bacteria cultured on this mannitol salt agar plate will have the same reaction. One reacted nearly 24 hours before the other. What substance in the agar was catabolized by both bacteria that produced the demonstrated colorimetric change? Image gallery (click for full size) (1pt 28) The presence of bacterial growth on this mannitol salt agar plate suggests that these bacteria can tolerate the hyperosmotic condition produced by the salt. The term used...
1 Why is mannitol salt agar considered a selective as well as a differential media?
help please On a mannitol-salt agar plate, a bacterium grows on the plate, and turns medium color from light orange to bright yellow. The color indicator is phenol red. This bacterium must be capable of: Select one: O a. Fermenting lactose to make acidic by-products. O b. Utilizing citrate as a main carbohydrate source to grow. O c. Fermenting glucose to make acidic products, which lowers the pH of the MSA agar. O d. Fermenting mannitol to make acidic products,...
Mannitol salt agar (MSA) is a both a selective and differential medium. Which of the following regarding MSA is TRUE? (There may be more than one answer) ( MSA turns yellow when bacteria are able to ferment maltose I MSA selects for acid tolerant bacteria () MSA turns yellow when bacteria are able to ferment mannitol MSA selects for salt tolerant bacteria
Microbiology - Gram Positive (ONLY answer) [Q1] Which organism did not ferment mannitol? [Q2] We observe color change on Mueller Hinton agar. (True/ False) [Q3] Which organism was resistant to novobiocin? [Q4] Your organism is catalase negative and produces a black precipiate on bile. What other test would likely be positive?
1.) How could MacConkey agar aid in the identification of coliforms? 2.) Streptococcus Uniate ferments mannitol. Could MacConkey agar be used to isolate S. iniae from a complex mixture?
Microbiology - Gram Positive (ONLY answer) [Q1] A clear zone on blood agar is also known as _____________ hemolysis. [Q2] Which organism is the only one that can grow in the presence of 6.5% salt? [Q3] What color would you observe for an organism that is negative for mannitol fermentation?
can somrone help me write an introduction for each agar. thank you ? Introduction: Selective and differential media are used frequently in Microbiology Pathology Labs to identify a known group of bacteria from a complex mix of other bacteria. The medium is designed to select against as many of the background organisms as possible by using a medium in which they will not grow but the organisms under investigation can grow hence the "Selective" part of the name. Any assayable...
