Comparison of the API Staph-Ident and DMS Staph Trac micromethods for the identification of coagulase-negative staphylococci.

Two rapid identification micromethods, the API Staph-Ident and the DMS Staph Trac, were compared for the identification of coagulase-negative staphylococci. Seventy-five isolates, mainly of bovine origin, were used as the test organisms. Species identification and profile numbers assigned to isolates by each system were compared. However, no clear correlation patterns emerged, indicating the two methods were not comparable.
