- QUESTION: Microbes from a blood culture inoculated with blood drawn from a catheter were determined by the appearance of growth on Mannitol Salts Agar and through other tests to be Staphylococcus epidermidis. It can be concluded that: a. a bloodstream infection caused by S. epidermidis is occurring in the patient from whom the blood was drawn b. The bacteria fermented mannitol, changing the color of the growth medium from pink to yellow. c S. epidermidis is present in the sample as a normal flora contaminant d. That in order to determine if a bloodstream infection is present, these results must be compared to a blood culture of a sample drawn from a peripheral veinQuestion 7: How could immunotherapy be used to kill superbugs and how would this therapy distinguish between bacterial cells and human cells?This is a molarity problem that I cannot figure out. If you could please help me understand the steps to solving it that would be greatly appreciated! Question: We need to prepare a stock solution of medium for your culture cells, which usually includes liquid salt solution and bovine serum. Our liquid salt solution is supplied in a 50X concentration, and we need to dilute it to 1X for use. We also need to add 75% fetal bovine serum for a final concentration of 15%. How would we make up 0.80 liters of this culture media using water as our solvent?
- Liquid supported membrane of DGA used for rare earth elements separation. Tell me the background/introduction of this research, current state of the art, motivation, how these membrane are made , what is the appropriate characteristics of them, approaches that author followed, you can describe the problems of that approaches, why rare earth is challenging to separate, why current state of the art do not address that need, include two or 3 results and describe it. take those information from few journal papers and mention the correct citation.Experiment #1 From Antoinette de Senna’s Master’s thesis on ‘Screening of biological control organisms for the management of phytopathogenic fungi and foodborne pathogens on produce’. Objective: To screen three LAB (Lactobacillus plantarum, Pediococcus acidilactici, and Pediococcus pentosaceus) for antimicrobial activity against the foodborne pathogens Listeria monocytogenes, Salmonella, and Escherichia coli. Methods: 1 ml of the pathogen was placed into a petri dish. Then, 15-20 ml molten tryptic soy agar (TSA) tempered to 50°C was added. When the TSA solidified, a loopful of LAB was spotted onto the agar. Plates were incubated at 35°C for 24 hours then the zone of inhibition was measured from the boarder of the bacterial colony to the perimeter of the clearing. Results: Questions: What is the independent variable? What is the dependent variable? Suggest a control for this experiment? What is the optimal temperature range for Listeria monocyogenes? Is monocyogenes a…The Mechanism of Action of Cyclophosphamide and its toxicity reference :http://dx.doi.org/10.3390/scipharm88040042 (reseach paper DOI plz answer in detail do not give short answer )
- Given this, if you used 6g of vitamin Z powder to make 20 ml of solution, what is the % concentration of this solution? (I gave the image since I don't know if that info is needed to solve this question.)It also gives a follow-up, if you can help here too: You work in a lab as a summer student. One of your tasks is to make sure that there is enough cell culture medium containing antibiotics to grow bacteria. One day you realize that there is only 5 ml of 10% Antibiotic stock solution in the freezer. You decide to use it all to prepare the working culture medium with 0.01% antibiotic. In the lab there is plenty of growth medium without antibiotics. (Note: dilution in medium is like dilution in water). You remember the equation to make dilutions of stock solutions. You usually use this formula to calculate the required volume of a stock solution, but you realize it can apply here as well, even though the unknown is the final volume. So, you make that dilution. Given that each bacterial…Antibiotic Code Zone of Inhibition (mm) S, I, or R? Penicillin P 15 Streptomycin S 8 Ampicillin A 25 Chloramphenicol C 14 Bacitracin B 5 QUESTIONS: Which antimicrobial agent was most effective against your organism? Can you determine from your results whether this antimicrobial agent will also be most effective against another bacterium? Why or why not? Is this technique measuring bacteriostatic effect, bactericidal effects, or both? Explain. 4) Consider the following list of hypothetical antibiotics, tested against Escherichia coli in a Kirby-Bauer test: Antibiotic Zone of Inhibition (mm) Astonostatin 12 Bodaciosporin 25 Crazifloxacin 5 Dorkimycin 16 When the above antibiotics were tested as treatments for E. coli infections in humans, it was found that Dorkimycin has virtually no effect on the infection, while Astonostatin is the most effective of the four antibiotics listed. Propose an explanation for this result. Based purely on these…Question 1: Suppose you have given 5 tablets weighing 449mg, 450mg, 448mg, 451mg and 453mg, respectively. Calculate 300 mg equivalent sample weight for assay. The product claim is 500 mg Vitamin C is present in each tablet. Question 2: Volume of the standard sodium edetate is 12.6 mL (calculated after the assay of Zinc Sulfate Syrup). Determine the % of potency of the drug considering the claimed dose is 11.5
