Textbook Question
Chapter 24, Problem 15PS
Tuberculosis (TB) is caused by a bacterium spread from person to person through the air. It affects the lungs, but can also affect the kidneys, brain, and spine. A simple diagnostic test for TB involves injecting antigen (from the bacterium that causes TB) under the skin and then waiting a few days for a reaction to appear. If a reaction occurs, a person has the TB infection (although the majority of people won’t develop an active disease with symptoms). Would this test be useful in diagnosing TB in patients with AIDS? Predict whether patients with both AIDS and TB infection would have a positive skin test or not.

If the person has been vaccinated against tetanus, he is given a booster which consists of the toxin. If the patient has never been vaccinated against tetanus, he is given an antiserum shot against tetanus. Explain the rationale for this treatment strategy. Sometimes both booster and antiserum are given at different locations of the body. Explain why this is done.
Before you can start your clinical rotation, you are required to get a tuberculosis (TB) test. The clinician injects a small amount of tuberculin purified protein derivative (PPD) under the skin of your forearm. Within about 30 minutes, you develop a swollen, itchy rash on your forearm where the PPD was injected. What type of hypersensitivity is this? What might have caused this result?
Two individuals are tested for Mycobacterium tuberculosis. Mycobacterium tuberculosis is isolated from patient number 1. Antibodies against Mycobacterium are isolated from patient number 2. Which person has the disease, or do they both?

- The vaccine for Haemophilus influenzae type b is called a conjugate vaccine. It is composed of the tetanus toxoid protein conjugated to the capsular polysaccharide of the H. influenzae type b bacteria. When used to vaccinate infants, the antibody response generated by this vaccine would include 0 0 0 0 antibodies that bind only to the protein-polysaccharide conjugate in the vaccine. antibodies to the tetanus toxoid only. antibodies to the bacterial polysaccharide and the tetanus toxoid. antibodies to the bacterial polysaccharide only.arrow_forwardMrs. Kirby is a volunteer at a hospice.

This patient is at risk for infection because of his low white blood cell count. 64-year-old African American male visits his primary care physician with complaints of bone pain, fatigue, nausea, loss of appetite, and constipation. The patient has a history of good health and exercises regularly. However, his recent symptoms have started to interfere with his active lifestyle. After a physical examination, his physician orders laboratory analysis to identify what might be causing his symptoms. Based on the CBC results and your knowledge of the cellular components of the immune system, what is an immunological concern for this patient? A). This patient is at increased risk for bruising and bleeding because of his low platelet count. B). The patient’s fatigue is caused by the lack of red blood cells (anemia). C).
