- What are the advantages and disadvantages of culture-dependent and culture-independent methods in microbiology, respectively.What is the difference between a mixed culture and a contaminated culture if they both contain more than one type of organism ?A microbiologist inoculates a growth medium with 100 bacterial cells/ml. If the generation time of the species is 1 hour, and the microbes are in the exponential (log) phase of growth, how many hours require for the culture to surpass 10,000 cells/ml, if the culture is checked once each hour? O 1) 2 hours O 2) 7 hours O 3) 3 hours O 4) 10 hours O 5) 24 hours
- Which one of the following microorganisms would you use as a quality control check to ensure that your sterile technique method is properly working? S. aureus, a gram-positive bacterium E. coli, a gram-negative bacterium B. cereus, an endospore-forming bacterium M. leprae, an acid-fast bacterium T. pallidum, a flagellated, disease causing bacteriumWhat is the advantage of culture-independent analysis over culture-dependent analysis of microorganisms?In microbiology, are there techniques that can help make Bacterial Culture and Sensitivity done faster?
- You are hired in one of the microbiology labs in Memphis and your first assignment to identify microbial samples from a local restaurant. You are given a set of slides and asked to classify the specimens as Gram positive or Gram negative. 9) What makes the bacteria Gram negative?10) Approximately how long would it take you to finish the entire procedureWhat are the physical requirements that must be considered when trying to grow microbes?Why is bacterial culture useful to grow bacteria?
- What are the disadvantages of doing a total microbial count by examining wet mounts under the microscope?In microbiology, the term growth in a culture usually refers to an increase in O 1) the number and size of microbial cells. O 2) the amount of ATP consumed. O 3) a microbe's size. O 4) the number of microbial cells. 5) the amount of ATP produced.Using the clinical question --"Does antibacterial foam decrease bacteria count on hands as much as hand washing with soap and water.” Question 1) Describe your study design and sample. 2) Will your findings be generalizable? Why or why not? 3) How does this exercise inform your interpretation of published research?.
