A metaphor is a very important and unique way to explain and express some particular phrases or scientific arguments, which help us to understand the writer’s ideas or concepts easier. In “Tinker, Bacteria, Eukaryote, Spy”, Asher Mullard uses many metaphors to help us explore and understand the relationship between bacteria and humans. Another example of this can be found in Kingsolver’s book, “Flight Behavior”. She uses metaphors to explain complicated concepts that lead us to a deeper understanding of her stories. Metaphors play a great role in many writings, but most importantly in scientific writing. In “Tinker, Bacteria, Eukaryote, Spy”, the author mentioned, “an extensive and cordial dialogue” (Mullard 161) in the last paragraph, which I think this is a very suitable metaphor for this writing.
We know that bacteria and their hosts may reside in different kingdoms, but the communication between them never stops. In this writing, the author uses many metaphors to describe how some of the bacteria act as a spy or stealth agent. The bacteria communicate with each other in their unique way. They are just like spies and they communicate through their high technology or secret languages with each other. However, the host’s immune system can detect those transmissions between the bacteria and try to use those messages to turn up against them, to stop them from taking advantage of the host body. Bacteria also can find out they have been listened to, so they will attack or shut down the immune system.
This kind of things happens every day inside the host body, just like a silent warfare. According to study and the reading from “Tinker, Bacteria, Eukaryote, Spy”, we know that “bacteria didn’t have the genetic power to do anything interesting – they ate, they moved, they divided.”(Mullard 159) But if something happened to them and caused them to mutate or disease themselves, then they will become harmful acc..
