Abstract: Medical articles include a tube prepared from a polymer composition containing one or more extractable components. At least a portion of the exterior surface of the tube contains an anti-microbial layer. A transparent vapor-deposited coating of a barrier polymer derived from at least one ethylenically unsaturated monomer covers the exterior surface of the tube. The barrier coating reduces the extraction of extractable component(s) from the tube, but permits the anti-microbial to pass through the barrier layer and provide anti-microbial activity on the barrier surface.

Abstract: Medical compositions and methods of suppressing microbial virulence are provided. By suppressing virulence, administration and/or application of the medical compositions can be used to prevent, mitigate, or treat a microbial infection. More specifically, the medical compositions include a phosphonate-containing polymer. The phosphonate-containing polymers can suppress the expression of various virulence factors without destroying all microbes that may be present.
