Solved in 2 steps
- a. If an egg salad sandwich sitting in a warm car for 4 hours develops 40,960bacterial cells, how many more cells would result in just one more generation? b. What would the cell count be after 4 hours if the initial bacterial dose was 100?c. What do your answers tell you about using clean techniques in food preparation and storage (other than esthetic considerations)?Mycobacterium tuberculosis is very difficult to stain because of the A) presence of ribosomes in the cytoplasm. B) location of the DNA within the cell. C) large amounts of a waxlike lipids present in its cell wall. D) lack of a cell wall.Which of the following is similar to a block of highly purified “jello-like” substance that is not completely solid and has numerous pores throughout its structure? A. Micropipette b. Restriction enzymes c. Agarose d. Negative electrode please give correct answer
- Are the bacteria that cause Lyme disease likely to develop antibiotic resistance? Why or why notGive the reason why is an organism such as Staphylococcus adapted to growth on the human skin but the streptococci are generally not shows?How do you think a bacterial cell would respond if it was treated with the antibiotic vancomycin compared to the antibiotic erythromycin? Note: this question is asking about the bacterial response, not the specific action of the antibiotic, although you need to know this to answer the question.
- a.explanation on how a cultured bacteria should be able to cause disease in healthy organism once inoculated. b.explanation on how the bacteria should be able to reisolated from the experimentally infected host organism and should show similar properties of the original bacteriaOne of the early results shows that the post-centrifugation pellet of encapsulated cells also contains EA1 and/or Sap. Why is this not proof that Bacillus anthracis cells have both an S-layer and a capsule simultaneously? I need help finding the answer in the article and explain in short answer link to article: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC106848/Infections among hospitalized patients are often related to the presence of a medical device in the patient. Which conditions favor the formation of biofilms on in-dwelling catheters?
- Explain how an enzyme can be useful in treating a bacterialinfection, such as that which occurs with cystic fibrosis.Why is biofilm development in catheters (tubes that can be inserted into a body cavity, duct or vessel which allow drainage or injection of fluids) such a dangerous source of infection in hospitals?Some potentially pathogenic bacteria and fungi, including strains of Enterococcus, Staphylococcus, Candida, and Aspergillus, can survive for one to three months on a variety of materials found in hospitals, including scrub suits, lab coats, plastic aprons, and computer keyboards. What can hospital personnel do to reduce the spread of these pathogens?
