摘 要 从3904例住院病人标本中分离出医院内感染病原菌781株，结合临床常用的14种抗菌药物药敏试验结果进行整理分析。结果，革兰阳性球菌所占比例呈上升趋势，革兰阴性杆菌呈下降趋势。引起医院感染的主要病原菌为真菌、大肠埃希菌、克雷伯菌、肠球菌、金黄色葡萄球菌。2年间金黄色葡萄球菌对青霉素的耐药率已>93%，对第三代喹诺酮类的耐药率下降了16.66%～40.83%。肠球菌对万古霉素的耐药率上升了27.59%。克雷伯菌、沙雷菌、大肠埃希菌对头孢菌素类、第三代喹诺酮类的耐药率呈上升趋势。金黄色葡萄球菌、表皮葡萄球菌、肠杆菌属、铜绿假单胞菌对阿米卡星的耐药率呈下降趋势。

Abstract 781 nosogenic bacteria separatedfrom the Samples of 3904 in-patients were tested With 14 ordinary clinical antibiotics andthe results were analysised.It showed that the Gram-positive cocci show the increasinglytrend,but the Gram-negative bacteria decreasingly.Among pathogens the most common wereFungi,Enterobacteria,Klebsillae,Enterococci and Staphylococci,During the last twoyears,the Staphylococci's penecillin-resistant rate increased above 93%, but their fluoroquinolone-resistant tate decreased 16.66% to 40.80%. Enterococci's vancomycin-resistant rate increased 27.59%.Klebsillae,Serratia and Escherichia's Cephalosporin-resistant rate and fluoroquinolone-resistant rate wereincreasingly.However,Staphylococcus aureus,staphylococcusepidermidis,Enterobacteria,ps.aeruginosa,Such Amikacin-resistant rate is decreasing.
