CoNS species determination
To further determine CoNS species, we performed a multiplex polymerase
chain reaction (PCR) assay using previously described primer sets (11,
12). Ten CoNS species, namely S. epidermidis , S.
haemolyticus , S. pasteuri , S. warneri , S. xylosus ,S. capitis , S. caprae , S. saprophyticus , S.
lugdunensis , and S. hominis , were determined by the presence and
size of the PCR product.
