ABSTRACT
Within the framework of the clinical study of the Erlangen silver catheter 104 silver catheters and 105 control catheters were tested by microbiological culture. This was done by rolling the catheter on a blood agar plate, washing the lumen through with tryptic soy broth (TSB) and, after ultrasound treatment, incubating the catheter tip in TSB as an enrichment culture for detecting very low bacterial counts. There was good agreement in the numbers of colony-forming units (CFU) detected by the roll plate and luminal washout cultures in 92% of the silver and 89% of the control catheters tested. Seventy-six (73%) of the 104 silver catheters showed no bacterial growth and 16 (15%) showed very low bacteria counts (< 15 CFU), or growth only after enrichment, which were attributed in both instances to catheter contamination. Twelve catheter tips (12%) showed significant bacterial counts greater than 15 CFU which were indicative of colonization or catheter-related infection. Corresponding results in the control catheters were 59 (56%), 28 (27%) and 18 (17%), respectively, a higher rate of infection or contamination which was statistically significant (chi-square test P = 0.04).
