摘要

We compared five swabs, dry or premoistened and with or without preenrichment, to detect surface contamination with Staphylococcus aureus. Sensitivities varied based on swab type, as follows: 71.9% and 75% for rayon, 71.2% for cotton, 81.3% for polyester, and 53.2% for calcium alginate. Preenrichment improved sensitivity (80%, versus 61.3% for direct-plated specimens), as did premoistening (83.4%, versus 57.5% for dry swabs). All of the premoistened, preenriched swabs were positive.
