Abstract
A polymeric tubular conduit including a polymeric tubular conduit wall having an outer tubular layer coaxially overlaying an inner tubular layer which defines a continuous tubular passage along a polymeric tubular conduit length of the polymeric tubular conduit; whereby the outer tubular layer, the inner tubular layer, or combinations thereof, include an amount of antimicrobial agent. The amount of antimicrobial agent can be sufficient to kill or inhibit growth of microorganisms in contact with a corresponding polymeric tubular conduit wall external surface, polymeric tubular conduit wall internal surface, or combinations thereof, of the polymeric tubular conduit wall.
