49例小儿败血症致病菌谱及耐药性分析

目的　了解小儿败血症患者病原菌感染谱及耐药性的变化。方法　对 1999年 1月 -2 0 0 3年 12月本院儿科住院的败血症患儿血培养阳性结果进行分析和总结。结果　 2 2 9例败血症患儿中分离出病原菌 49株 ,其中葡萄球菌最多 ,占总数 63 .3 %。药敏实验结果表明大部分G 球菌对青霉素和头孢类等常用药物耐药。结论　葡萄球菌是小儿败血症的主要病原菌。细菌对常用的抗菌药物耐药比例较高 ,应引起临床的高度重视

Characteristics of Pathogens spectrum and Drugs resistance in 49 children with Septicemia

Objective To study the characteristics of pathogens spectrum and drugs resistance in children with septicemia.Methods The results of blood culture of children with Septicemia in our hospital from 1999 to 2003 were analyzed.Results Forty-nine strains of bacteria were isolated from 229 children with Septicemia.Staphylococcus were the most pathogens that positive ratio was 63.3%.Resistance of most Gram-positive organism to penicillin and cephalosporin were produced.Conclusions Staphylococcus was the main pathogens causing Septicemia in children.The most pathogens were resistant to commonly used antibiotics,we must think much of these in our clinic practice.
