Use the scenаriо belоw tо аnswer аll parts of the question. Your patient is a young child that while playing received a large, deep splinter that deposited Staphylococcus aureus from the patient’s skin deep into the sterile subcutaneous tissue. The infectious bacterium originated on the patient’s skin where it had been part of the skin microbiome the patient’s whole life. Now the bacterium is causing a serious infection. A) Is this Staphylococcus aureus a primary pathogen or an opportunistic pathogen? What evidence do you have to support your decision? B) A wound of this kind will cause an inflammatory response which will trigger the four stages of the early immune response. What are the four stages and at which stage might the bacterium be directly killed by the immune system? C) This is the patient’s first infection with Staphylococcus aureus. There are currently no available vaccines for Staphylococcus aureus. A B cell encounters the bacterium swimming freely in the blood stream. Name the two cells that the B cell will differentiate into upon activation by the pathogen. What is the first type of immunoglobulin that will be produced after differentiation? What is the second?
