These include enzymes, pili for attachment and tissue degrading factors. a) Disease b) Virulence c) Cosmic d) All of the above 17- Certain strains of Neisseria gonorrhoeae can avoid destruction by host IgA antibodies by a) Acquiring a capsule b) Destroying the C3a complement component c) Rapid turnover of the pili that binds to the antibody 18- True or False 19- True or False 20- True or False d) All of the above A condition of high viral count in the blood stream is known as Viremia. In a localized infection, the microbe is spreading throughout the body A discase like chicken pox is highly communicable 21-Antimicrobial drugs may work by interfering with a- Cell wall synthesis b- Nucleic acid synthesis c- Protein synthesis d- All of the above 22- The cephalosporins work by inhibiting a- Cell wall synthesis b- Nucleic acid synthesis c- Disrupting cell membrane integrity d- None of the above 23- True or False The macrolides are a type of antibiotic that interferes with protein production 24- True or false Tetanospasmin is an A-B toxin secreted by Clostridium tetani responsible for spastic paralysis. 25 The cause of strep throat is A. Staphylococcus aureus B. Streptococcus pyogenes- beta-hemolytic, group C.

16. b
Virulence factors aid a pathogen in infection of the host.
18. True
Viremia leads to increased viral load within the bloodstream which can then spread to other sites like CNS.
19. False
Localized infection means local infection of a tissue. It does not spread to other parts of the body.
20. True
It is a highly contagious disease spreading through sneezes and coughs of an infected person.
21. d
Antibiotics can inhibit cell wall synthesis like penicillin, inhibit protein synthesis like puromycin or inhibit nucleic acid synthesis like ciprofloxacin.
22. a
Cephalosporin disrupt synthesis of peptidoglycans in cell walls of bacteria.
23. True
Macrolides inhibit protein synthesis by inhibiting peptidyltransferase activity, ribosomal translation, and premature dissociation of peptidyl tRNA from the ribosome.
