Table S2: Sensitivity and specificity of surveillance cultures (SC) for the identification of a number of nosocomial pathogens in ET biofilms. Data of single SC and of the recommended combinations are shown. TS: throat swabs; NS: nose swabs; SS: sputum samples -: As there were no oxacillin sensitive specificity could not be calculated. M. luteus, Tobramycin, ciprofloxacin and meropenem resistance and ESBL production was not considered. Also, for resistance to fluconazole and amphotericin B was not C. albicans, included in this table.
