Which is the vector (animal that carries the pathogen) for West Nile virus?
-
Sorry, that’s incorrect.
The mosquito is the vector for West Nile virus. The mosquito suffers no ill effects from the virus but transmits it to humans and other warm-blooded creatures (such as crows) when it takes a blood meal.
-
Correct!

True or False: Thimerosal, a mercury-containing preservative that was used in some vaccines and other products, has been shown to present a risk to human health.
-
Sorry, that’s incorrect.
The use of thimerosal has been an object of controversy, with some arguing that the substance caused autism in children. However, extensive independent research has presented no convincing evidence of harm associated with the low levels of thimerosal previously present in vaccines.
-
Correct!

True or False: Not all microbes are harmful to humans.
-
Correct!
Not all microbes are harmful to humans. In fact, many of them protect us, helping our bodies function properly and competing with harmful organisms in an eternal contest for habitable space in or on our bodies. Although the microorganisms that cause disease often receive more attention, most microorganisms do not cause illness.

For each child who dies from pneumonia in an industrialized country, about how many children die from the infection in developing countries?
-
Sorry, that’s incorrect.
Life-saving vaccines and medications aren’t distributed equitably around the world; for each child who dies from pneumonia in an industrialized country, more than 2,000 children die from the infection in developing countries.

“Antibiotic resistance” refers to:
- The reluctance of physicians to prescribe antibiotics
- An underground movement against pharmaceutical companies
- The ability of bacteria to resist the effects of an antibiotic
-
Sorry, that’s incorrect.
“Antibiotic resistance” refers to the ability of bacteria to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria undergo a genetic change that reduces or eliminates the effectiveness of drugs or other agents designed to cure or prevent infection.

Which reproduce the fastest:
-
Sorry, that’s incorrect.
Viruses reproduce the fastest. Humans produce a new generation every 20 years or so; bacteria do it every 20 to 30 minutes, and viruses even faster.

About what percentage of the antibiotics produced in the United States is added to animal feeds to promote growth?
-
Sorry, that’s incorrect.
Almost 70% of all the antibiotics produced in the United States is added to animal feeds—not to fend off disease but to boost growth. These non-therapeutic uses of antibiotics are a perfect way to cultivate microbes that are resistant to antibiotics.

True or False: Antibiotics work by introducing an agent that resembles a disease-causing microbe, thus stimulating the body's immune system to recognize it as foreign, destroy it, and "remember" it, so that it can more easily identify and destroy any similar, disease-causing microbes that it later encounters.
-
Sorry, that’s incorrect.
The above describes how vaccines work. Antibiotics work by either killing bacteria or stopping them from reproducing, allowing the body's natural defenses to eliminate the pathogens.
