| Abstract |
Staphylococcus argenteus is a new species of coagulase-positive staphylococci. S. argenteus is very similar to S. aureus in biochemical properties and cannot be distinguished by routine testing. However, this isolate differs from S. aureus in that it does not produce a yellow pigment and forms white colonies. We report the first case of vascular access infection caused by S. argenteus in a female patient in Japan.
She had symptoms of redness at the insertion site of the vascular access and fever, which were relieved by Cefazolin. S. aureus-like colonies were obtained from the blood cultures submitted to the laboratory. The isolates were identified as S. argenteus by PCR of the non-ribosomal peptide synthetase (NRPS) gene and sequencing of the rpoB gene. The result of multi-locus sequence typing analysis showed that the sequence type was ST2250. In Taiwan, 11 isolates (7.3%) of the 150 isolates from vascular access infection were reported to be S. argenteus, all of which were ST2250.
The relationship between S. argenteus and vascular access infection should be focused on in future studies. |
