People have managed to import them so you would have to follow what they did to accomplish it. It might turn out to be the only working solution.
In the meantime I suggest that you research Efflux Pump Inhibitors for the bacteria because that would help prevent them from eliminating antimicrobials and then many things, including silver, would be far more effective. There are different groups of Efflux pumps and various herbs etc can deactivate a bacteria's efflux pump. They use the efflux pump to help them to eliminate things which are harmful to them. The hard part is matching the bacteria to the EPI. It's whether there is any research on EPI for that bacteria. Check out my post in the eBooks forum for links to some sites which prove useful.
