①The collected clinical Acinetobacter baumannii isolates were more seriously resistable to Ciprofloxacin than to Imipenem;②The antibiotic resistance of clinical Acinetobacter baumannii isolates may be associated with the decline of CarO protein expression;③There is some relationship between CarO protein and ciprofloxacin-resistant Acinetobacter baumannii strains,it proves that CarO protein supports bacteria on multi-drug resistance;④CarO protein may be related to cell signalling;⑤The difference in CarO protein functional sites and structure between the sensitive strains and the resistant strains may be related to bacterial resistance.

为了了解我国几个不同地区旋毛虫之间的种属关系，我们对这些地区的旋毛虫进行了线粒体细胞色素氧化酶亚单位I基因的扩增，并得到了正确的COI基因。

Results By MSHA/MRHA, the fimbriae of 4 of the 5 isolates were identified as type Ⅲ, and the rest one as undefined type. However, by PCR, all the fimbriae of 5 isolates were identified as type Ⅲ.

结果 MSHA/MRHA方法鉴定其中的4株菌具有Ⅲ型菌毛，另外1株无法鉴别，而PCR方法鉴定5株菌均具有Ⅲ型菌毛。

We use whole soya beans and not protein isolates because soy protein isolates are one of the most refined soy products available.

我们选择完整大豆而不是分离蛋白制作豆奶，因为分离大豆蛋白是精加工提炼过的，在提取的过程中大部分的营养元素已经丢失。

Three hundred and twenty-five isolates of Magnaporthe grisea collected from rice plants in Wujiang, Yixing, Tongzhou, Gaoyou and Ganyu of Jiangsu province from 1997~1999 were tested for mating type and fertility with standard tester strains. Seventy-four tested isolates produced perithecia after mated with tester strains, in which, 48 were MAT1-1 and 26 were MAT1-2 mating type.

用标准菌株对1997~1999年在江苏省吴江市、宜兴市、通州市、高邮市和赣榆县采集的325个稻瘟病菌单孢分离菌株的可育性和交配型进行了测定，结果表明江苏省稻瘟病菌菌株的育性较低，可交配率为22.77%，可育率仅为7.08%。

The three isolates were named A/Bar-headedGoose/Qinghai/F/2006(H5N1), A/Black-headed Gull/Qinghai/3/2006(H5N1) andWhooper Swan/Qinghai/01/2006(H5N1). The research results were, nucleotidesequence analysis revealed that three isolates shared a high homology with each other(99%) except PB1 genes of Bar-headed Goose/Qinghai/F/200 and Whooperswan/Qinghai/01/2006, which shared 94% identity.
