answ:c??????

i think e is the answer...compared to glutaraldehyde ,quartenary ammonium compounds have a very narrow spectrum of activity.

a fine mnemonic to remember this is GCIPQ ,highest action is glut,chlorine,iodophors,penolics and least is quart (starting with highest ending with least)
hope this helps

a. An allergic reaction to insect venom
b. The classical pathway of complement
c. The destruction of virus-infected cells by T-killer cells
d. The production lgG in response to insect venom
e. The alternative pathway of complement

answ:e

i think the ans for above question is d ..coz Innate immunity is present from birth, and the information for innate immune responses is inherited...which means it must b b'coz of production of igG which is the only Ig to cross placenta and also the first line of defense...

pls do correct me if its wrong..

12. Coagulase production by staphyloccous eureus is important in pathogenicity because it
a. helps to establish the typical abscess lesion
b. helps to establish the typical cellulitis lesion
c. allows the organisms to adhere tightly to tissue
d. provides a polysaccharide capsule to inhibit phagocystosis
e. non-specifically binds to the Fc portion of lgG molecules


answer is c --- Coagulase is an adhesin produced by Staphylococcus aureus to localize an area of residence that converts fibrinogen to fibrin. In laboratory, it is used to distinguish between different types of Staphylococcus isolates. Coagulase negativity excludes S. aureus.

what is your source?
you said so, "In laboratory, it is used to distinguish between different types of Staphylococcus isolates"
the question refers to pathogenisity, I think the problem was bet a) abcess and b) cellulitis ..............I found the answer in the microbiology kaplan book. I am pretty sure the answer is abcess (A)
