① They are called super bacteria.
② MDR tuberculosis bacillus is a superbacterium of tuberculosis.
③ It can occur when the drug is not taken regularly.
④ It can be treated with several currently developed antibiotics.
⑤ Even if you take the drug regularly, you may develop super bacteria.
3. Choose the wrong one among the principles of antibiotic development.
① Culture E. coli resistant to all antibiotics on the market.
② Every day, the microbes pour the liquid containing E. coli little by little into the culture dish.
③ Observe whether the microorganisms in the soil kill the E. coli.
④ After a few days, when the transparent part spreads from the soil grain, the enhanced super E. coli is destroyed.
⑤ When developing an antibiotic, it can only be made using soil.
4. Which of the following statements about vaccines is incorrect?
① The smallpox vaccine was developed by Jenner.
② The rabies vaccine was developed by Pasteur.
③ Smallpox vaccine is made using the vaccinia virus.
④ It is different from the principle that antibiotics kill bacteria.
⑤ Vaccines kill viruses by using defense mechanisms in the human body.
5. Which of the following statements about the immune system when the virus enters is incorrect?
① When a virus enters the body, basically two immune mechanisms work.
② Anti-protein surrounds the virus and prevents it from entering the cell.
③ Nevertheless, when it enters the cell, the killer T cell works.
④ Killer T cell kills virus-infected cells, but only the virus attacks.
⑤ The virus dies and antibodies and Killer T cells remain to attack the virus.
6. Choose the one that fits the characteristics of the AIDS virus.
① It destroys the immune system itself.
② When the AIDS virus invades, anti-protein surrounds it. It destroys the immune system itself.
③ AIDS virus attacks Killer T cells and cannot destroy helper T cells.

② measles
③ polio
④ Mumps

① R&D costs are high, so the burden is high.
② The practicality of antibiotics is low, so the profits are not large.
③ The currently developed antibiotics are sufficient.
④ Even if the experiment is successful, the probability of failure is high when applied to clinical practice.
⑤ It takes a lot of time.
10. Which of the following statements about the immune system is incorrect?
① Killer T cells directly kill things like viruses.
② Killer T cells are activated by helper T cells.
③ Killer T cells attack viruses that do not raise their own MHC.
④ Helper T cells secrete IL-2 to activate killer T cells.
⑤ Killer T cells produce antibodies.
