摘要
目的分析本院新生儿血培养标本各种病原菌分布情况及主要病原菌的耐药特点。方法选择儿童专用培养瓶,采用BACT/ALERT3D全自动血培养仪对患儿血液标本进行血培养,分离所得菌株用MICROSCANPc12/NC21鉴定药敏系统进行鉴定和药敏试验。结果血培养结果以革兰阳性球菌为主,占73.1%,其中以表皮葡萄球菌为主,占革兰阳性球菌的50%;革兰阴性杆菌占25%。革兰阳性球菌对万古霉素均敏感;革兰阴性杆菌对碳青霉烯类抗生素高度敏感。结论新生儿血培养阳性结果对危重患儿的抗菌治疗提供了实验依据,对患儿的治疗、抢救有着积极意义。
Objective To investigate the distribution and antibiotic resistance of pathogens isolated from blood specimens of neonates.Methods Bact/Alret 3D automated blood culture system was used to culture the blood of the newborn.Isolated strains were identified and their drug sensitivity tests were completed by MICROSC ANPc12/NC21 automicroscan.Results Gram-positive cocci were in the majority （73.1%）,in which staphylococcus epidermidis accounted for 50%;and gram-negative bacteria accounted for 25%.Gram-positive cocci were sensitive to vancomycin,and gram-negaitive bacteria were sensitive to carbapenems.Conclusion In order to provide therapy for neonates septicemia,it is necessary to monitor the distribution and the resistance of pathogens isolated from blood samples
