| 摘 要： | 目的 了解临床常见肠杆菌科细菌产AmpCβ-内酰胺酶的产生率。方法 采用头孢西丁筛查试验和三维提取试验对170株茵进行检测。结果 头孢西丁筛查试验阳性29株，三维提取试验阳性5株，可疑4株。结论 头孢西丁筛查试验特异性较差，假阳性高；三维提取法能准确检测AmpCβ-内酰胺酶，其产生率达2.94％。

| Abstract: | Objective:To study the occurrence rate of AmpC Beta-Lactmases of clinical bacteria. Methods:To detect 170 isolates by cefoxifin screening test and three-dimensional extract test.Results:29 strains yielded a cefoxifin zone diameter less than 18mm (screen positive), The three-dimensional extract test identified 5 strains producing AmpC Beta-lactamases and 4 strains are suspicious.Conclusion:The cefoxitin screening test has poor specificity ;the three-dimensional extract test may accurately identify the AmpC Beta-Lactamases, its Occurrence rate is 2.94%. |
