Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most dangerous organisms that can be encountered in the health care setting. MRSA is often resistant to more than one antibiotic. 1. What does it mean to say that S. aureus is resistant to methicillin? 2. What antibiotic would you choose to combat this micro-organism? 3. What are some clinical consequences for the patient infected with MRSA? Edit View Insert Format Tools Table В І 12pt Paragraph UA T² V fil <

Questions 40 and 42.

in the article the “Overall, the composition of the cores and insides of the Gouda cheeses were more similar to each other based on sequence reads than to the samples taken under the rind.” (pg 3 last paragraph)   i need helpexplaning what this mean in simpler language, and if this makes sense given the differences between these locations?

Louis Pasteur said, “The role of the infinitely small in nature is infinitely large.” Explain what he meant, using examples of the roles of microorganisms in health, industry, and the environment.

Q1: What is the difference between MRSA and VRSA? Q2: Why is there a clear zone (the “zone of inhibition”) around the paper disk in the top dish but not in the bottom dish? Q3: Why is the lack of a clear zone around the paper disk in the bottom dish so alarming?

Use the following diagram to explain how Pasteur’s swan-necked flasks prevent contamination of sterile broth the flasks.Describe what happens to the sterile broth (a) after it has beenallowed to cool as in (b). What happens to the broth after theflask has been tipped enough to let the broth come in contactwith the dust and microorganisms and is tipped back as in (c)?

B. culture the blood or other body fluid from a diseased animal using nutrient medium.   C. inject a sample of blood or other body fluid from a diseased animal into a healthy animal. D. obtain a sample of blood or other body fluid from a diseased animal.

Pasteur’s experiments on spontaneous generationcontributed to the methodology of microbiology,understanding of the origin of life, and techniques for thepreservation of food. Explain briefly how Pasteur’sexperiments affected each of these topics.

In 1864, Lister observed that patients recovered completely from simple fractures but that compound fractures had “disastrous consequences.” He knew that the application of phenol (carbolic acid) to fields in the town of Carlisle prevented cattle disease. Lister treated compound fractures with phenol, and his patients recovered without complications. How was Lister influenced by Pasteur’s work? Why was Koch’s work still needed?
