Exam 4: Microbial-Immunity

Match the description of a vaccine in questions with the correct type of vaccine (A-G). -Good induction of mucosal immunity but risk of developing a viral disease,especially in immunocompromised hosts

Some viruses evade CTL-mediated immunity by expressing molecules that have which of the following actions?

For each of the descriptions of immune mechanisms in questions ,select the immune mechanism (A-D)that correctly matches it. -Innate immunity mechanism for preventing viral infection of cells

Match the description of a vaccine in questions with the correct type of vaccine (A-G). -Induction of a T cell-dependent antibody response to polysaccharides,such as Haemophilus influenzae B and pneumococcal capsular polysaccharides

For each of the descriptions of immune mechanisms in questions ,select the immune mechanism (A-D)that correctly matches it. -Innate immunity mechanism for eradicating viraly infected cells

For each of the descriptions of immune mechanisms in questions ,select the immune mechanism (A-D)that correctly matches it. -Adaptive immunity mechanism for preventing a viral infection

Match the description of a vaccine in questions with the correct type of vaccine (A-G). -Composed of viral proteins synthesized from recombinant viral genes

Match the description of a vaccine in questions with the correct type of vaccine (A-G). -Composed of a recombinant nonpathogenic virus carrying genes of a pathogenic virus,such as HIV

For each of the descriptions of immune mechanisms in questions ,select the immune mechanism (A-D)that correctly matches it. -Adaptive immunity mechanism for eradicating established viral infection

A common strategy by which microbes survive their host's immune responses involves changing the structures of the molecules they produce so that they are no longer recognized by the host's immune system.This strategy,called antigenic variation,is most likely to allow evasion of which type of immune recognition?

Protection against extracellular bacterial infections such as with staphylococci,and extracellular fungi,,such as with Candida,is in part mediated by which of the rolling types of T cell responses?

Match the description of a vaccine in questions with the correct type of vaccine (A-G). -Composed of antigens purified from microbes or inactivated toxins,such as the tetanus toxoid vaccine
