Characterization of S. aureus growth on polyvinyl chloride endotracheal tubes coated with titanium dioxide with silver over a 144-hour period. Comparison of standard, solgel titanium dioxide with silver and Degussa titanium dioxide with silver endotracheal tubes. There was no difference in S. aureus growth in the titanium dioxide with silver-coated groups compared to standard endotracheal tubes except at 144 hours with solgel titanium dioxide with silver endotracheal tubes.
