Question

What will be the outcome when R-strain is injected into the mice?

• A. Mice dies as soon as it is injected
• B. Mice lives with the bacteria and dies suddenly
• C. Mice dies after ejecting out the bacteria
• D. Mice lives even after injecting the R-strain of the bacterium

Answer 1

Answer:

D. Mice lives even after injecting the R-strain of the bacterium

R-strains are the non-virulent strains. So, when they are injected into the mice, they won’t cause any damage to it. As a result, the mice will be able to live without complications. The bacteria contain both the S and R strains, but, only the R-strain is being injected in this scenario.
