Lab tests showed that the plasmid could easily move between E. coli strains, transforming polymyxin-sensitive strains into polymyxin-resistant ones. But, the plasmid had a harder time moving between different bacterial species. The researchers had to coax the plasmid into other species by zapping bacterial cells with an electrical pulse to make their membranes more permeable
This is the good news. It can move between strains of E. coli, but they had to artificially induce it to share the gene with different strains of bacteria.

It's not as good news as you think.
The point is that it is recievable into the cytosol and still functional of different species.
E. coli cell dies, bursts, and releases the plasmid in the environment. If the bacteria in the environment is stressed, they tend to pick up whatever DNA is floating in the environment.
