Figure 1From: The antimicrobial effect of Octenidine-dihydrochloride coated polymer tracheotomy tubes on Staphylococcus aureus and Pseudomonas aeruginosa colonisationComparison of S. aureus colonization on OCT coated versus uncoated tracheostomy tubes. Mean cfu concentration [log-] after standardized contamination with S. aureus before any reprocessing [T1], after 5 rounds of reprocessing [T2] and an additional 5 reprocessing procedures [T3]. OCT coated tracheostomy tubes are represented by gray bars, uncoated tubes by white bars.Back to article page
