Methods A total of 1 147 blood samples were aerobically cultured by BACTEC 9050 in thishospital from Sept.1996 to Mar.1999.The positive rate,false-positive rate,false-negative rate and the time needed to positivity were analysed,respectively.

使用BACTEC 9050全自动血培养仪对1 147例血标本进行需氧培养，分析阳性率、检出菌的种类、阳性检出时间、假阳性和假阴性。

One ESBLS-producing strains was detected in Pseudomonas aeruginose,Enteric aerogenes and Citrobacter,respectively.

由于ESBLS阳性株对临床常用抗生素的耐药率远远高于ESBLS阴性株，使临床治疗面临极大的困难，必须引起临床医生和临床微生物室的重视。

This method inhibits the growth of gram-positive and gram-negative microorganism, e.g., S. aureus, S. epidermidis, K. pneumoniae, E. aerogenes, and E. cloacae.

该方法抑制了革兰氏阳性和革兰氏阴性微生物的生长，例如金黄色葡萄球菌、表皮葡萄球菌、肺炎克雷伯氏菌、产气肠杆菌和阴沟肠杆菌。

Results the leading bacterias separated were coagulase-negative staphylococcus, enterobacter cloacea, staphylococcus aureus, escherichia coli and enterobacter aerogenes.

结果：致病菌前5位依次为凝固酶阴性葡萄球菌、阴沟肠杆菌、金黄色葡萄球菌、大肠埃希氏菌、产气肠杆菌。

Pyridoxal phosphate-dependent HDC are encountered in Gram-negative bacteria belonging to various species (i.e. Raoultella planticola, Enterobacter aerogenes, Photobacterium phosphoreum, etc.) Takahashi et al. 2003; Morii et al.

磷酸吡哆醛依赖HDC的是遇到革兰阴性菌属于不同的物种（即Raoultella planticola，产气肠杆菌，发光菌，等）（高桥等人。2003年；森井等人。2006年）。

Ammelide was detected in one sample (20.1 ppm) and the other 26 samples were negative.

Ammelide检测一个样本（ 20.1分钟）和其他26个样本均呈阴性反应。

Information was available on ammelide and ammeline in 20 samples; 18 samples were negative and two were positive for both compounds.

信息可在ammelide和ammeline在20个样品； 18个样本均呈阴性反应，两人都积极的化合物。

Two samples were positive for cyanuric acid (2.11 and 2.63 ppm), one was positive for ammelide (13.9 ppm), and all other results were negative.

两个样品呈阳性反应，氰尿酸（ 2.11和2.63百万分之一），一个是积极的ammelide （ 13.9分钟），和所有其他结果均为阴性。

Nine samples had detectable levels of ammeline (Range of 1.2 to 24.9 ppm) and the other 18 samples were negative.

9个样本，检测水平ammeline （幅度为1.2至24.9分钟）和其他18个样本均呈阴性反应。
