- EXPLAIN THE PURPOSE OF THE METHYL RED AND VOGES-PROSKAUER TESTS IN DETERMINING THE IDENTITY OF GRAM NEGATIVE ORGANISMS IN THE FAMILY ENTEROBACTERIACEAE. INCLUDE IN YOUR ANSWER WHY METHYL RED IS USED RATHER THAN PHENOL RED. WHAT ORGANISM IN THE FAMILY IS USED AS A CONTROL WHEN RUNNING THE METHYL TEST. IF THE METHYL RED TEST IS NEGATIVE, EXPLAIN WHY THE VOGES-PROSKAUER TEST IS RUN AND INCLUDE WHAT COLOR CHANGE INDICATES A POSITIVE TEST. ACCOUNT FOR THE COLOR DIFFERENCES IN THE NEGATIVE VOGES-PROSKAURER TESTS. WHAT REAGENTS (COMMON NAME) WERE USED IN THE VOGES -PROSKAUER TEST.In a Triple Sugar Iron test, what are the results and (what should they look like) for the bacteria: Enterobacter aerogenes, Pseudomonas aeruginosa, Salmonella typhimurium, and Serratia marcescens?in the document you submit, please describe the results for this test… (like yellow equals what?) Methyl Red and Voges-Proskauer (MRVP) Test: 1) Give me the expected results for Enterobacter aerogenes and Escherichia coli (for each bacteria, give me the MR result and VP result)
- For which of the five hydrolysis tests (starch, casein, triglycerides, tryptophan, and urea) would a positive test result be expected for: a. the etiologic agent of acne, Propionibacterium acnes? Explain. b. the etiologic agent of gastric ulcers, Helicobacter pylori? Why would this activity be advantageous in this environment?How do the methyl-red and Voges-Proskauer tests differentiate between certain members of the Enterobacteriaceae?Please explain briefly how the Bile Esculin Test works. How is a positive test attained? What does the positive test tell us?
- Your organism is a Gram-negative organism (Enterobacter aerogenes) You must discuss all the IMViC tests and Hydrogen sulfide test in DETAIL. How can this be explained in lamen terms the step by step results of enterobacter aerogenes? DISCUSS all the results. Discuss in a logical and step by step fashion how you concluded that you had a certain microorganism.You need to explain which observation(s) enabled you to identify your unknown microorganism (Enterobacter aerogenes).To convince your reader you need phrases like; This observation “suggested” that my organism is Enterobacter aerogenes This observation “confirmed” that my organism is Enterobacter aerogenesIf the five-digit code that is tabulated cannot be found in the EnteroPluri-Test Codebook, what that indicate about the bacterial culture?Vibrio cholerae can be cultured on Thiosulfate-Citrate-Bile salts-Sucrose agar (TCBS).
