“The researchers used sensitive equipment to measure the mechanical forces that four different antibiotics exerted on bacterial cells.” I would like to see this “equipment” as it must be very, very small to put it lightly.
Electron Microscopes and their calculations were but estimates. The calculations may be right and perhaps not. I would suspect they are looking at the molecular bonding forces in the cell membrane of the bacterium and what is needed to force it apart. This is really rocket science with "wag" also known as "wild ass guess." I hope they are right.

And, 1% to 3% of your body weight is benign or symbiotic bacteria.
Did I forget to mention the mites that live inside your eyelash follicles?
