Chapter 2, Problem 3Q
Often bacteria that are freshly isolated from a patient or the environment have thick sugary outer layers (capsules). After they are transferred many times on laboratory medium, they tend to lose their capsule. Speculate about why that might happen.

Note that it is not appropriate to self-diagnose outside of a medical context and this is a completely hypothetical scenario.
Imagine you have a rash on your foot. You're concerned that it's an infection and inoculate a sample onto an agar plate. You wonder, How can I figure out whether the pathogen is a bacterium vs a eukaryote?
You decide to use lab supplies to get a basic understanding of the pathogen. Be specific about what tests you use and what you expect the results to be. Limit yourself to experiments we could do in our lab.
What is one experiment you could do, involving culturing the organism?

Write a paragraph for when you once have Neisseria gonorrhoea bacteria in its pure form, what methods can you use to confirm the identity of this bacterium as N. gonorrhoeae? Mention what is the principle of those methods.

- A lab technician is working with a bacterium in pure culture (in 5 ml of liquid media in a test tube). The bacterium is a mesophile that can infect humans. Which of the following is NOT true (with regards to temperature conditions for this bacterial culture)? Lowering the temperature to -10 deg C for at least an hour will likely kill all the bacteria. Placing the tube at 37 deg C will likely facilitate rapid growth of the bacteria. Raising the temperature to 90 deg C for at least an hour will likely kill all the bacteria. Placing the tube at 4 deg C will likely slow or halt growth of the bacteria.arrow_forwardThe number of bacteria in a sample can also be quantified with other techniques, such as examination with a microscope. Why might this method not be as accurate as the plate count method?arrow_forwardIf you looked under a microscope and found colony of perfectly round bacteria, all in a straight line.

- There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiple the series of dilutions together to find the final dilution value. If 3 serial dilutions are performed, each with a value of 0.01, what is the cumulative dilution? Express your answer as an exponent, e.g. 0.1 would be 1e-1 and 0.01 would be 1e-2arrow_forwarddiscuss which two rooms in your home or workplace that you believe are the most contaminated.

- I'm having trouble identifying the type of bacteria I have cultured. I know that it is gram-negative and cocci in shape, it grows wonderfully on the MSA plate but did not grow so well on the EMB plate, and it is non-motile. It has a yellow color but I'm just not sure what it is. It was obtained from a public area. Any ideas?arrow_forwardA microbiologist is working with a pure strain of bacteria isolated from a mixed sample. Which of the following would indicate that the bacterium is NOT Streptococcus mutans? Cells are arranged in chains. Secretes acids produced from metabolism of sucrose. Cells are cocci. Can grow in biofilms. Cells stain Gram negative.arrow_forwardYou are working for the CDC studying outbreaks of foodborne infectious disease. Your latest case is an incidence of food poisoning in a fast food restaurant. 5 people have been hospitalized for food poisoning, so you are working with that hospital to identify the source of the outbreak. Hospital clinicians have taken samples from each of the 5 patients for culturing. Each bacterial culture grew one likely microbe, each labelled P1, P2, P3, P4, and P5. All 5 isolates appear to have the same colony morphology on the plates, and all appear to be Gram-negative rods 1 micron wide and 3 microns long under the microscope. In addition, all 5 isolates appear to perform the same on an API 20E test strip that tests bacteria for 20 biochemical abilities. No other testing has been done yet. How would you best describe your set of isolates at this moment? O Each isolate is the same strain, of a different species O Each isolate is a different strain, of different species O Each isolate is a different…arrow_forward
