includes the following isolates: S. lugdunensis (2); S. capitis, S. epidermidis, S. schleiferi subsp. coagulans, and S. xylosus (1 each); and unspeciated staphylococci (3).
bMethicillin resistance (tested with oxacillin disk and a chromogenic medium) was not detected in any of the S. pseudintermedius or S. schleiferi isolates.
