Question 33 You are coordinating a medical response to a Hepatitis A virus outbreak. Applied passive specific immunity will be most helpful in preventing disease in individuals who have been infected with the virus, but are not yet symptomatic. Which of the following apply. OA transfer of Hepatitis A virus specific Tc cells O B. transfer of pooled Hepatitis A virus specific IgG O C. transfer of Hepatitis A virus specific plasma cells O D. transfer of Hepatitis A virus specific antigen presenting cells (APC) O E none of the above apply Question 34 Question 35 Which of the following is specific to the immediate events of innate immune system inflammation: OA secretion of cytotoxins perforin and granzyme 8 by Tc cells OB. diapadesis of neutrophils into the tissues OC. secretion of IL-2 OD. vasodilation, vascular permeability, and cell adhesion molecule (CAM) expression OE secretion of tumor necrosis factor (TNF) alpha OF. none of the following occur during the immediate events of inflammation 2 pt O A complement directed lysis by Ight OB. ADCC-opsonization and agglutination by IgG 2 pts Which of the following will be MOST important antibody function(s) in the clearance of a bacterial species that synthesizes attachment pili for infection of the intestinal tract: OC neutralization by IgA OD association with mast cells to release histamines, prostaglandins, and leukotrienes by E OE induction of perforin and granzyme B synthesis by Tc cells 2 pts
0 Question 36 Which of the following apply to the purpose of the TORCH test: OA the test determines infections with pathogenic teratogens OB. the test determines infections with the mumps virus OC. the test determines infection with Group B streptococcus O D. the test determines the severity of measles virus infection O E. the test determines the severity of polio virus infection Question 37 A bacterial pathogen can synthesize a capsule composed of mannose complexed with sialic acid, secretes enzymes that degrade C3a and C5a, and a C3b binding protein. All of the following components of the innate immune system will be subverted or evaded by this pathogen EXCEPT: O A recognition of DAMPS by Toll-like receptors (TLRs) on macrophage O B. chemotaxis of white blood cells to the site of the infection OC membrane attack complex (MAC) formation OD. opsonization (innate system) OE adherence of phagocytic cell TLRs to microbial PAMPs for phagocytosis OF. release of TNF alpha and histamine, leukotrienes, and prostaglandins from mast cells Question 38 Which of the following contribute to the functional antibody protein structure: O A TCR O B. CD4 OC.CDB O D. CD20 OE Light chains 2 pt 2 pts 2 pts
