Antigen is injected through vaccination into the same site as a previous injection of
that same antigen. Antibody-antigen complexes deposit in basement membranes of
the epithelial tissues. Neutrophils infiltrate and degranulate, destroying tissue in that
localized area. What is the name for this reaction?
O
1) granulomatous reaction
2) arthus reaction
3) serum sickness
4) contact dermatitis
A person with type A+ blood gets a transfusion
with type O- blood. What is most likely to happen
to the recipient?
A) The recipient's blood will agglutinate
(clump) due to the presence of natural
antibodies in the recipient's blood.
B) Nothing because the donor's blood is
compatible with the recipient's blood.
C) The recipient's blood will agglutinate
(clump) due to the presence of natural
antigens on the recipient's blood cells.

-  A 27-year-old man has had a fever and cough for four months . Auscultation of the chest discloses crepitant crackles confined to the apex that persist despite coughing. An x-ray off the chest shows enlarged hilar lymph nodes. Acid fast stain of the sputum is positive. Which of the following characterizes the cellular host reaction? A) Humoral antibody formation of B lymphocytes B) interferon gamma production by CD4 T lymphocytes C) interferon gamma production by CD8 T lymphocytes D) macrophage lysis by B lymphocytes E) macrophage lysis by CD4 T lymphocytes arrow_forward(56) A 1 year old boy dies of staphylococcal pneumonia. He has had multiple skin infections since birth. Separation of the umbilical cord was delayed. A skin window test was performed and no leukocyte accumulated on the cover ship. The cytometric analysis showed that only 5% of the T lymphocytes reacted with a monoclonal antibody to leukocyte functional antigen-1 chain (CD 18) compared with reactivity of 62 % for a normal subject. Just prior to death, his leukocyte count was 75,000/mm3. Which of the following is the most likely diagnosis?
