1, A patient with a fever, sore throat with patches of pus and swollen lymph nodes in the neck is confirmed to have a strep throat

List 2 tests that can done in the microbiology lab ( Identify specific tests that we did in the lab portion of the class only ) to confirm the presence of the organism.

2, A patient was recently exposed to the Sars-CoV-2 virus and has no symptoms . The patient uses a rapid test at the home 3 days, 4 days, and 5 days after exposure . the rapid tests are negative for 3 and 4 days after exposure but is positive after day 5.

Explain these findings, why are the tests giving different results?

3, A patient recently exposed to Sars-CoV-2 virus (in the past week) has a fever, shortness of breath and cough the patent was immunized against the virus a month a ago. Explain what is occurring in the immune response beginning with cross- presentation by dendritic cells to activation of helper- T cells . uses as much detail as possible to answer the question, reflecting the process at the molecular level ( be sure to include receptors specific cells that are involved, etc.)

4, If you wanted to determine the penicillin antibiotic to use for a patient with strep throat how would you proceed? Explain your answer
