(a)
To determine:
Which type(s) of medium would be used in isolating the growth of Streptococcus pyogenes from a patient's throat swab.
Introduction:
Streptococci are the most predominant flora found in the respiratory tract of human. Streptococcus pyogenes is a species under Streptococci family and it is an obligate human pathogen, and also the major cause behind human mortality throughout the world due to respiratory diseases.
(b)
To determine:
Which type(s) of medium would be used in isolating the pathogen from a patient's clean-catch urine sample.
Introduction:
A clean catch is a method of collecting a urine sample for the diagnostic purpose. This method is important for preventing the germs from the penis or vagina from entering inside the urine sample. Urinary tract infections (UTIs) are included among the most common bacterial infections. These infections lead to inflammation and over growth of uropathogens.
(c)
To determine:
Which type(s) of medium would be used in isolating the isolating enteric bacteria such as Escherichia coli from a sample of organically grown spinach.
Introduction:
The presence of Escherichia coli in crops indicates a fecal contamination. This bacterium, is isolated from the intestines of warm-blooded vertebrates, is released into the environment through feces. E. coli contamination in the fields occurs from various sources, such as contaminated soil, fertilizer, and irrigation water.
(d)
To determine:
Which type(s) of medium would be used in maintaining a patient's nasal swab specimen for further analysis and identification of possible respiratory syncytial virus (RSV) infection.
Introduction:
Respiratory syncytial virus (RSV) is one of the most common respiratory pathogen, causing infections of the lower respiratory tract within people of all age groups and in immunosuppressed patients, specific diagnosis of RSV infection is based on the detection of virus or “virus specific

- Anwser these Discussion Questions: Part One Why were the plants kept in the dark prior to the experiment? Why is this important? Why is it important to boil the leaf? Explain why it was necessary to use boiling alcohol? What is the purpose of the iodine? Part Two What was the purpose of keeping the leaf in the dark and then covering it with a cardboard cut-out? What conclusions can you draw from this part of the lab? Part Three 7. In this experiment what was the purpose of adding the soda lime? 8. Why was a sealed bag placed around each plant? 9. What happened in the control plants? 10. What was the result on photosynthesis? Part Four 11. Why was a variegated leaf used in this experiment? !2. What conclusions can you draw about starch production in a variegated leaf?arrow_forwardHow did the color differences between the two bacterial species you used in this experiment help you determine if the streak plate method you performed was successful?arrow_forwardseries of two-point crosses were carried out among six loci (a, b, c, d, e and f), producing the following recombination frequencies.
