The majority of Gram positive coccus were coagulase-negative staphylococci.

球菌中凝固酶阴性葡萄球菌占绝大多数。

Results Coagulase negative Staphylococci (CNS) accounted for more than 50% every year.

结果凝固酶阴性葡萄球菌（CNS）检出构成比历年居于5 0 %以上。

Objective: To evaluate the clinical significance of coagulase negative staphylococci (CNS) in blood culture.

目的：评价血培养中凝固酶阴性葡萄球菌(CNS)阳性的临床意义。

To study the influence of slide coagulase test on determining the staphylococcus aureus (sa) with GPI assay.

目的了解玻片法凝固酶试验在GPI卡鉴定金黄色葡萄球菌(SA)中的影响。

The strains were tested with catalase and coagulase tests, biochemical experiments were used to identify the strain.

对分离的菌株，用过氧化氢酶和血浆凝固酶试验后，用生化实验对菌株进行鉴定。
