Abstract

A total of 126 coagulase-negative staphylococci strains (CNS) were isolated from blood samples and from the intravenous catheters and cerebrospinal fluid of 103 patients admitted to the University Hospital of Ribeirão Preto. Staphylococcus epidermidis (68.2%), S. haemolyticus (11.1%) and S. hominis (3.2%) were the most frequent species. The last two CNS showed greater resistance to antimicrobial agents than S. epidermidis. CNS were the agents of infection in 10. 7% of the patients and the agents of intravenous catheter colonization in 18.4% of the cases.

摘要

从里贝朗普雷图大学医院收治的103例患者的血样、静脉导管和脑脊液中总共分离出126株凝固酶阴性葡萄球菌（CNS）。表皮葡萄球菌（68.2%）、溶血葡萄球菌（11.1%）和人葡萄球菌（3.2%）是最常见的菌种。后两种CNS对抗菌药物的耐药性高于表皮葡萄球菌。CNS是10.7%患者的感染病原体，也是18.4%病例中静脉导管定植的病原体。
