Rabies is a viral zoonosis that is transmitted directly from the bite of an infected animal. The rabies vaccine is prepared by treating virus with a chemical that renders it unable to infect and replicate. What type of vaccine is this? a. whole cell b. attenuated c. subunit  d. inactivated

the antibody produced in the secondary response a. IgM b. IgA c. IgG d. IgE

Why is there an enzyme attached to the secondary antibody? a. They provide a colormetirc indication of antigen exposure b. They link to the proteins used c. They are used to detect DNA

of the choices, which cells stimulate directly B cells to divide and produce antibodies? a. mast cells b. marcophages c. Nk cells d. TH cells

d,e,f

An MLS has completed an antibody panel using PEG. She cannot exclude anti-Fya, or anti-E. Anti-Kpª and anti-Ja cannot be excluded either but they are low incidence antigens and the MLS is not concerned with those at this time. What would be the next logical step to aid in antibody identification? a. Run the panel again using ficin treated cells b. Run the panel again using 22% albumin for enhancement c. Pay special attention to the strength of the agglutination reactions d. Run the panel again but increase the 37 degree incubation time to one hour

Which of these immunopathologies could be treated with a stem celltransplant?a. arthus reaction b. SCID c. anaphylaxis d. a and b only e. b and c only
