- Which of the following best describes an attenuated whole-agent vaccine? Uses antigenic fragments of a microbe to stimulate immunity Uses living but weakened microbes to stimulate immunity Uses killed microbes to stimulate immunity Combination of antigens to enhance immune response Inactivated toxin (toxoid) that induces immunity against microbial toxinAttenuated organisms often provide a weak or short-lived immune response. Vaccines containing toxoid are used when the pathogenicity of the organism is a result of the secreted toxin. BOTH statements are TRUE FIRST statement is TRUE; SECOND statement is FALSE BOTH statements are FALSE FIRST statement is FALSE; SECOND statement is TRUEWhich of the following statements correctly compares/contrasts the ways in which antibiotics and antibodies interact with the cells of pathogens that they can affect during an infection? Group of answer choices Antibiotics and antibodies both enter cells and kill them Antibodies enter cells and kill them; antibiotics attach to the outside of cells Antibiotics enter cells and kill them; antibodies attach to the outside of cells Antibiotics and antibodies both attach to the outside of cells
- If you gain immunity to an antigen by receiving a vaccine this is: Natural passive Artificial passive Natural active Artificial activeWhich of the following best describes an attenuated whole-agent vaccine? Which option is the answer... Inactivated toxin (toxoid) that induces immunity against microbial toxin Uses living but weakened microbes to stimulate immunity Combination of antigens to enhance immune response Uses killed microbes to stimulate immunity Uses antigenic fragments of a microbe to stimulate immunityTrue or false Edward Jenner first proposed protective vaccine against plague in the 18th century. Herd immunity protects infection of vaccinated population but not in the unvaccinated population. Long term health problems after COVID-19 infection is called Long COVID. Cerebellum of the brain co-ordinates muscle movements. Neuron is a special type of cells in the brain and nervous system.
- Briefly explain where each antibody comes from in the examples below. When cold ends antibodies come from. Partially alive, weakened or dead pathogen vaccine. A fetus receiving IgG from a virus through a placenta. Anti venom used for a snake bite.Vaccines can be made for many types of pathogen, such as bacterial and viral pathogens. True The whole statement is true. False Some of the statement is false.Positive and negative controls must be included in any immunoassay. Controls are always run before the experimental samples to establish validity of sample results. A false positive may result from the contamination of the sample with the antigen. only the 1st statement is true only the 2nd statement is true only the 3rd statement is true the 1st and 2nd statements are true the 2nd and 3rd statements are true the 1st and 3rd statements are true all the statements are true all statements are false
- In which of the following cases would treating a patient with an antiserum (purified antibodies) be more helpful than treating them with other drugs? Group of answer choices Purified antibodies would not be helpful in any of these cases If the person has a viral hepatitis infection If the person has eaten a poison produced by bacteria If the person has a fungal skin infectionThe process where antibody will cause microbes to be connected together so they can no longer cause infection is called: excision inactivation coarctation agglutinationThe figure below shows antibodies bound to repetitive epitopes on the surface of a bacterial pathogen. Even though all of these epitopes are identical, not all of them have antibodies bound to them. The most likely explanation for this failure of antibodies to bind to every possible epitope on the surface of the pathogen is: There is an insufficient amount of antibody to saturate all the epitopes. The pathogen has an immune evasion strategy to avoid antibody binding to all epitopes. Some of the epitopes cannot bind antibody due to steric hindrance. The antibodies are only able to bind when both antigen-binding sites are engaged on the pathogen surface. The epitopes on the pathogen are not all in the same conformation, so not all will bind the same antibody.
