Staphylococcus pseudintermedius confirmed by biochemical test
To determine the subgroup of the isolated staphylococcus , its biochemical reactions to 16 designated reagents were tested. The results in Table 2 showed that the designated reagents including sucrose, urea, arginine dihydrolase, xylose, lactose, mannose, maltose, trehalose, N-acetylglucosamine and fructose are positive to the isolated strain, but negative for wood alcohol, mannitol, nitrate, VP-MR, melibiose and sorbitol. Especially, the positive responses to maltose, trehalose and mannitol in Fig.3 can confirm that the isolated pathogenic bacterial isStaphylococcus pseudintermedius , but not Staphylococcus intermedia and Staphylococcus delphini .
