Hello, please read the attached Microbiology question and answer the question correctly.  *If you correctly answer the question, I will provide a Thumbs Up to you. Thank you.

Question:- Describe control strains used in the clinical microbiology laboratory and explain their maintenance in the laboratory. ( write BY WORD and all steps I need). Introduction Discussion References

Activity 2. Media Used in Isolating Coliforms You are a group of microbiologists tasked to test the presence of coliforms in the newly built water station. You are asked to isolate E. coli, Salmonella, and Shigella. Enumerate the media used for each step of isolating these bacteria. Include pictures and references. Bacteria Enrichment (Broth/Agar) Presumptive test (Broth/Agar) Isolation Media (Broth/Agar) E. coli Salmonella Shigella 1. How can you confirm that E. coli, Salmonella, and Shigella are present in the newly built water station? Explain. 2. What is the difference between nutrient broth and nutrient agar? 3. What is the importance of these steps (Enrichment, Isolation, and presumptive test) in isolating bacteria? Conclusion about the process of isolating bacteria

Please explain college Microbiology for me

Name: Chemotaxis Lab Worksheet 1. What is a model organism and why is it important to scientific studies? List two common model organisms, one for prokaryotic studies and one for eukaryotic studies.

Please use this submission link to submit your flowcharts. You will need to submit a total of three flowcharts, one for each of your unknown microorganisms (gram positive rod, gram positive coccus, and gram negative rod). Please make sure that you only use the allowed tests: and microorganisms to complete your flowchart. You must identify each of the allowed organisms to a tip on the flowchart. Each organism must take no more than 3 total tests to completely identify   POSSIBLE MICROBES & ALLOWED TESTS                       MICROBE Gram rxn/shape Catalase Activity Mannitol/High Salt (growth/ferm) H2S prod.

site your reference:) What are the basic concepts and precautions to be observed in specimen collection for Microbiological examination? Enumerate specific examples of clinical specimens collected for microbiological examination. Give 2 specific examples of bacteria isolated from clinical samples. What is a transport medium; give specific examples and state their purpose.

Before viewing a specimen of pigmented bacteria on a slide under the light microscope, which of the following usually needs to happen (and why)?     Staining (to increase magnification).     Heat, radiation or antimicrobial chemical treatment (to kill the bacteria for safe observation).     Add immersion oil (to increase resolution).     Add a cover slip (to reduce contamination).     The viewing chamber needs to be flushed of air (to create a vacuum).

Hello, please answer the following Microbiology question correctly and fully. Please explain your answer. Question: Why is it necessary to inoculate the KIA medium all the way down to the bottom of the tube during inoculation? (What's different about the top and the bottom of the tube?)  *If you correctly answer the question correctly, I will provide a Thumbs Up to you. Thank you.

INSTRUCTION: Answer the question properly Do not copy in Google, plagiarize checker will be used. QUESTION: Discuss the various theories on the Gram stain.
