I was reading recently that with burns wounds many bacteria form biofilms, and these can "protect" the bacteria from many treatments as they are a sort of slime that prevent access to the bacteria surface.
I am not sure if this simple understanding is correct, anyone know more about bacteria and biofilms?

I wonder how well 327 will go getting past biofilms if they are present. It seems like the ideal treatment for severe burns infections would be the surface application along with the IV treatment as it seems the more severe burns often lead to sepsis.
I am guessing biofilms are not such an issue in bloodstream, but I am no scientist.
