You’ve been working with them for weeks.
You were careful to keep them at the right temperature so they wouldn’t die.
You gave them nutrients so they thrive and survive.
They became your friends. You could almost embrace them and say “how are you this morning?”
Because you’ve worked with them for a while, it’s safe to say you have developed a working relationship with them yes? Yes.
Over weeks, you develop a personal bond with these things you’re working with – bacteria. You have USED these bacterial cells to generate multiple copies of a plasmid vector. They cooperated and gave you all – more than what you required, and for that, you should be thankful.
After all that service they rendered, Dr P says they are no use anymore, “Drop them in the bin.” You could feel like you were betraying your bacterial friends. I slightly hesitated when I had to discard my Petri dishes with all the nice blue and white colonies on them. But what use were they now? They had done their job and it was time to let them go.
That tells you how quickly we form relationships with people, animals and even bacteria. It’s a human function.
We are all in a happy (sometimes unhappy) relationship with bacteria. They contribute more to your body weight than the cells that make up you! As helpful as they could be to your body metab, they could be your worst enemies upon changing conditions. There is that flip side to the tale.
But every once in a while comes a time to let go.. to move on.
