HSS1100 Final Exam Ques&ons:
1. List all the 've steps in virus replica&on (in the correct order). STEPS only. No need for explana&on.
[10 points at 2 marks each] Adsorp&on, penetra&on and uncoa&ng, synthesis of nucleic acid and
protein, assembly and matura&on, release
2. What are the three most important factors in hospital nocosomial infec&ons? (3 points) Source, route
of transmission, and host
3. Name 5 di+erent types of ac&ve immuniza&on. GENERIC names, not SPECIFIC NAMES>. (5 points)
Live-a*enuated vaccine, killed vaccine (or toxoid), recombinant vaccine, absorbed vaccine, conjugate
vaccine
4. Matching de'ni&ons to statements:
- autoclaving, pasteuriza&on, ionizing radia&on, nonionizing radia&on, moist heat (5 points)
- Autoclaving - most common, no air involved, saturated (vapour) and dry (no droplets) steam because if
its wet it soaks fabrics, impedes heat transfer and prolongs drying &me
- Pasteuriza&on - heat below boiling point to destroy vegeta&ve form of pathogen, usually for heat-
sensi&ve liquids Ionizing radia&on - enough kine&c energy to liberate electrons from atoms (most UV,
gamma)
- Non-ionizing radia&on - does not have enough energy to ionize atoms (microwave)
- Moist heat - irreversible decontamina&on of proteins by coagula&on
5. THE ORDER OF RESISTANCE IN NOCOSOMIAL INFECTIONS SECTION: (5 points) Bacterial spores and
protozoan cysts --> mycobacteria --> fungi --> vegeta&ve bacteria --> enveloped viruses
6. Associate a bacteria or virus name with the statement: (THERE WAS 5)
a) A virus that involves animal vaccine. Rabies Virus
b) The pathogen involved with cat feces. Toxoplasma Gondii
