摘要
目的了解医务人员鼻腔携带表皮葡萄球菌耐药情况及是否存在其流行株。方法对我院医务人员鼻腔表葡菌携带调查。结果发现其携带率为６１．９５％，儿科、神经外科工作人员携带率分别为８８．８９％、８９．４７％，经质粒及质粒限制性内切酶分析证实：极大部分工作人员鼻腔携带菌质粒图谱各异，而小儿科、神经外科有少数菌株质粒酶切图谱相同，说明可能存在交叉感染。结论本组菌株β－内酰胺酶阳性率为８５．９３％，ＭＲＳＥ检出率为７５．００％，此与医务人员长期接触β－内酰胺类抗生素有关；本组菌株粘质阳性率为２３．４３％，说明医务人员携带以正常菌为多。
OBJECTIVE In order to investigate the Staphylococcus epidermidis antilbiotics-resistance in noses of medical staffs and find out the epidemiological strains in our hospital were studied. METHODS We investigated the Staphylococcus epidermidis in noses of medical staffs in our hospital. RESULTS The carry rate of the whole examinee was 61.95%. Pediatric and neurosurgical department were 88.89%、88.47% respectively, plasmid and plasmid restriction endonuclease analysis proved that most plasmid fingerprintings were different, a few plasmid fingerprintings of pediatric and neurosurgical department were the same, to show the cross infection may existed. CONCLUSION The positive rate of β-lactmase showed of our strains was 85.93%, rate of MRSA was 75.00%, which was related with the contact of medical staffs and β-lactmase antibiotics the positive of slime production of our study was 23.43%, our investigation showed that most carry strains and a few strains were invasive strains.
