We compare the ability of a new sampling method (DC pad) with Rodac contact plate to detect a contamination due to filamentous fungi (FF) of surfaces in operating rooms (ORs). The study refers to the results of 84 sampling campaigns. Surface samples were collected from the scialytic lamps: half of upper surface was sampled with two Rodac contact plates. The other half of upper surface was all rubbed with one DC pad. The Χ2 test and Wilcoxon two sample test were used to compare the proportions of samples positive for FF and the difference in CFU of fungi collected. Overall, 89.3% of the DC pad samples and 44.0% of the Rodac plates were positive (p<0.005). The average number of CFU of FF collected on scialitic lamps was significantly higher using DC pads than Rodac plates (9.7 versus 1.5; p<0.001).

Abstract
We compare the ability of a new sampling method (DC pad) with Rodac contact plate to detect a contamination due to filamentous fungi (FF) of surfaces in operating rooms (ORs). The study refers to the results of 84 sampling campaigns. Surface samples were collected from the scialytic lamps: half of upper surface was sampled with two Rodac contact plates. The other half of upper surface was all rubbed with one DC pad. The Χ2 test and Wilcoxon two sample test were used to compare the proportions of samples positive for FF and the difference in CFU of fungi collected. Overall, 89.3% of the DC pad samples and 44.0% of the Rodac plates were positive (p<0.005). The average number of CFU of FF collected on scialitic lamps was significantly higher using DC pads than Rodac plates (9.7 versus 1.5; p<0.001).File | Dimensione | Formato | |
