102. A 29-year-old woman who is an intravenous drug user is found to have increased serum AST and ALT activities. Immunologic testing shows positive results for hepatitis B surface antigenand total antibody to hepatitis B core antigen, and negative results for IgM antibody to hepatitis B core antigen. This patient will recover from this hepatitis B virus infection and be protectedfrom subsequent similar infections with this virus if she generates which of the following immune responses?A) Cytotoxic T-lymphocyte responseB) Production of neutralizing antibodiesC) Type II (complement-mediated cytotoxic) hypersensitivity responseD) Type III (immune complex-mediated) hypersensitivity responseE) Type IV (delayed) hypersensitivity response

(53) A immunosuppressive 47-year old woman who receives a renal allograft develops cytomegalovirus(CMV) pneumonia. A clone of CMV specific CD8+ cytolytic T lymphocytes from an HLA matched donor is grown in tissue culture in the presence of a cytokine and is subsequently transfused into the patient to treat the CMV infection. Which of the following cytokines is most likely to support the growth of cytolytic T lymphocytes in the tissue culture? (A) Interferon gamma '(B) Interleukin-1 (IL-1) (C) IL-2 (D) IL-3 (E) IL-4 (F) IL-5 (G) IL-6 (H) IL-7 (I) Transforming Growth Factor Beta (H) Tumor necrosis factor Alpha
(>1 ans) Which of the following statements is/are correct? Hepatitis A viral infection will result in long-lasting immunity against subsequent infection. For disinfection of enteroviruses, such as hand-foot-mouth disease viruses, acidic disinfectant is effective. Prior rotaviral infection may not prevent subsequent infection of the same virus. For poliovirus and enterovirus-71, both neutralizing antibodies and cellular immunity are critical for defending the host against the pathogens. There is an effective vaccine available for noroviral infection due to its availability of animal models.

Smallpox has been widely reported as a possible bioterror weapon. Given what you know about the etiology of the disease and the current state of the world’s immunity to smallpox, discuss how effective (or ineffective) a smallpox weapon might be.

Donna suddenly developed a sore throat accompanied by a fever of 103°F. When over-the-counter medication was ineffective, Donna sought the advice of her doctor. He took a throat culture and, anticipating that it might be a bacterial infection, he began her on a 10-day regime of antibiotics. Why is it important that the doctor confirms this is a bacterial infection, before prescribing antibiotics? Would the doctor prescribe antibiotics if this was a viral infection?
