3. what I meant was there are different ways

bacteria can respond to an antibiotic. For example, altering the permeability of the cell membranes, altering the drug target structure inside the cell and creating compounds such as enzymes to degrade or destroy the antibiotic, etc.
These and other methods of genetic transfer to other bacteria occur under pressure from antibiotics.
The book I was reading said that the antibiotics incite and speed the process - "several orders of magnitude," causing communication across bacterial species lines. Such communication was not known to exist before the introduction of commercial antibiotics.

Sharing resistance information can occur through encoding plasmids, using transposons and integrons and using viruses.

I am not a scientist - just someone who is interested in learning about antibiotic resistance. From what I have learned - we are in big trouble. The nature of bacteria to share survival techniques puts them way ahead of out efforts.
