Update)
Question 1: A litter of kittens arrives at an animal shelter, and the kittens have various
multifocal, raised, minimally haired skin lesions. The attending veterinarian believes these
lesions are suggestive of ringworm. What can the veterinarian do to prevent an outbreak of
ringworm among cats in the shelter?
Answer: Isolate the kittens from other animals because dogs and cats are susceptible to ringworm
Question 2: Approximately 40% of people receive the inactivated form of the influenza virus
vaccine annually. What does this fact imply regarding public health?
Answer: The value of influenza virus vaccination for everyone could be better communicated to the
public.
Question 3: The label for one of the influenza virus vaccines states that the vaccine is "indicated
for active immunization for the prevention of disease caused by influenza A subtype viruses and
type B viruses contained in the vaccine" (U.S. Food and Drug Administration). Which impact
can this have on public health?
Answer: The vaccine will protect vaccinated people from an influenza virus that undergoes antigenic
drift.
Question 4: Smallpox is a highly contagious, fatal disease that has been eradicated since 1980.
The smallpox vaccine contains a poxvirus similar to the virus that causes smallpox. Why does
the vaccine contain a virus similar to the one that causes smallpox rather than one that contains
the actual virus that causes smallpox?
Answer: The similar poxvirus does not cause a smallpox infection, whereas the actual virus does.

Answer: Plasmids carry genetic material, apart from the genome, that can benefit the organism
Question 12: Which statement describes bacteria?
Answer: Some bacteria have cell walls composed of mycolic acid.
Question 13: Which aspect of nutrient cycling is performed only by prokaryotes?
Answer: Nitrogen fixation
Question 14: Which microbial process is useful in the production of alcoholic beverages?
Answer: Glucose fermentation
Question 15: How does microbial bioremediation benefit the environment?
Answer: By helping to metabolize and remove pollutants in the atmosphere
Question 16: How is penicillin classified?
Answer: As a natural antibiotic
Question 17: What describes the relationship of pathogens to virulence?
Answer: Highly virulent pathogens almost always lead to a disease state when introduced to the body.
