NAME

Grades will be curved providing you correctly answer at least 2 of these:

B1. The difference between general immunity and specific immunity is:

(a) general deals with defenses all mammals have, while specific is what only one species has.
(b) general deals with the killing most invading pathogens, while specific kills only one sort of pathogen
(c) general is relegated to biochemical allergies, while specific deals with fighting microörganisms
(d) general employs white blood cells while specific employs red blood cells
(e) there are no recognized activities called general and specific immunities
Specific immunity is directed at one or closely related antigens; general is at most antigens. Specific involves antibodies.

 A4. Which of the following include only antibodies

(a) IgG, macroglobulin, immunoglobulin, IgA
(b) T-killer cells, allergens, carcinogens
(c) anti-polio gamma globulin, macrophages, platelets
(d) pollen, heavy strands, IgM
(e) all of the above
antibodies and complement are mere proteins and not cells. Above items in green are cells or cell-like.

IMPORTANT: antibodies are one of your immunological defense weapons; antigens are what the antibodies target. Antigens are usually small pieces of the pathogen's clothing such as a smidgeon of LPS on a bacterium, or a projecting protein on a virion, or even a trace of malarial "underwear" exposed in a gap in the plasmodium's outerwear.

F2. Another name for a lymphocyte is:

(a) leukocyte
(b) white blood cell
(c) phagocyte
(d) erythrocyte
(e) both a and b
(f) a and b and c

F5. The immunological anamnestic response means that

(a) the immune system is permanently shut down
(b) serum complement remembers former invaders so that it is ready for a new assault
(c) it is a form of leukemia
(d) some lymphocytes phagocytize erythrocytes in the normal cycling of RBC's
(e) both c and d
(f) none of the above
The anamnestic response is that your body doesn't forget how to make antibodies it learned how to make when it fought the same infection at a previous episode.

any3. (WARNING!*) Upon microscopic examination, which figure best represents Gram-stained Streptococcus lactis:


This was graded loosely as such staining is highly variable. That's why the texts' explanations didn't match.

any6. (WARNING!*) You have a Gram-stained mixture of Streptococcus lactis and Streptococcus faecalis. Which photomicrograph best illustrates this mix.


This was graded loosely as such staining is highly variable. That's why the texts' explanations didn't match.
