Homework Answers
Answer:
For isolating the growth of streptococcus pyogenes from a patient’s throat swab we generally use a selective media. It is a type of media which inhibits the growth of any other microbe and encourages the growth of a particular microbe. Even differential media is also often used. For e.g the blood agar media is used.

A strain of Streptococcus pyogenes isolated from a throat swab was tested for sensitivity to ampicillin and tetracycline. The following results were obtained: Zone of Inhibition around ampicillin disk = 25 mm Zone of Inhibition around tetracycline disk = 21 mm Explain why the physician prescribed tetracycline instead of ampicillin. FOR FURTHER RESEARCH Most microorganisms that cause disease in humans are mesophiles. However, poorly maintained hot tubs can be a source of thermophiles that can cause human infections. List at...

If you want to develop a growth medium that selects for the growth of fungi, and deters the growth of bacteria, would you make this medium neutral, acidic, or alkaline? explain your answer. What oxygen requirement would you expect from an organism that grows throughout a soft agar deep, with more growth at the surface than at the bottom? Give an example of a genus of a bacteria that has the previously mentioned oxygen requirement.

Delia, a five-year-old, woke up one morning complaining that she had a sore throat, headache, and stomachache. Her tonsils appeared swollen, and a tonsular exudate, appearing as a cream-colored pus, was evident upon examining the child’s oropharynx. Her mother also took Delia’s temperature and noted the girl was running a low-grade fever. Suspecting strep throat (streptococcal pharyngitis), her mother made an appointment with the pediatrician. The doctor first performed a rapid strep test, which works by detecting certain cell surface...
