Question

Bacteria and bacteriophages are undergoing an evolutionary battle. In particular, phages that infect Salmonella enterica can use outer membrane proteins, such as OmpF or TolC, for drug efflux or to attach to the bacterial surface. What would be the impact of a significant mutation of these phage proteins? Choose one:

A. The efflux proteins would denature, but Salmonella would not become susceptible to drugs and phage infection.

B. The efflux proteins would denature, and Salmonella would become susceptible to drugs and phage infection

C. There would be no impact on the rate of phage infection for Salmonella.

D. The phage may not be able to bind to Salmonella's surface, blocking viral infection.

Explanation / Answer

Answer:

Bacteria and bacteriophages are undergoing an evolutionary battle. In particular, phages that infect Salmonella enterica can use outer membrane proteins, such as OmpF or TolC, for drug efflux or attach to the bacterial surface. Impact of a significant mutation of these phage proteins The phage may not be able to bind to Salmonella's surface, blocking viral infection

The phage may not be able to bind to Salmonella's surface, blocking viral infection

Hence, option(D) is correct.
