  • The API STAPH-IDENT system was evaluated as a means for identifying Staphylococcus hyicus subsp hyicus straints isolated from swine and poultry. Of 80 strains from swine, 68 (85%) were correctly identified by the API STAPH-IDENT system alone after 5 h of incubation. When results were determined after 24 h of incubation, the accuracy of this system alone was 93.8%. By additional tests in conjunction with the API STAPH-IDENT system, however, all 80 strains could be correctly identified. Of 120 strains from poultry, 87 (72.5%) required additional testing to achieve a correct identification, and 33 (27.5%) were incorrectly identified by this system after 5 h of incubation. After 24 h of incubation, 99 of 120 (82.5%) avian strains were incorrectly identified as Staph epidermidis owing to false-negative mannose and trehalose utilizations. Seventy-seven (96.3%) of swine strains were positive for ${\beta}-glucuronidase$, whereas all 120 strains recovered tram poultry were negative for it.

  • The result of API staph-ident system was compared with cellular fatty acid composition for the identification of Staphylococcus species isolated from cattle. Isolated strains from cattle were correctly identified to S aureus, S intermedius, S hyicus, S simulans, S saprophyticus, S epidemis, S sciuri and S xylosus by API staph-ident system. The correlation between bacterial cellular fatty acid profile and Staphylococcus species isolated to API STAPH-IDENT system were. In conclusion, the result presented indicate that Staphylococci can be indentified to the species level by the cellular fatty acid profiles. Moreover, computerized fatty acid profile correlative anaylsis can be applied for determining identify of Staphylococcus species.
