So it is assumed that the E-box might be associated with the enhancement of transcription activity.Here, the LTRs of WH17 ,DLA-25,DLA-118 and LTR with single mutation in the E-box motif were separately cloned into pCAT-Basic vector resulting in a series of recombinant plasmids containing CAT reporter under the control of different versions of LTRs.

通过对EIAV分离株WH17的LTR与L株、DA和DLA株的LTR序列进行比较，发现其在在U3-R结合处多一个E-box基序，推测该基序的变化可能会起到促进转录作用，为此将EIAV强毒株(DLA-25)、驴白细胞弱毒株(DLA-118)、EIAV分离株WH17以及U3-R结合处的E-box基序点突变的LTR分别克隆到pCAT3-basic质粒中的报告基因氯霉素乙酰转移酶的上游，获得一系列受不同LTR控制的CAT表达质粒。

Results: The clinical manifestations of paratyphoid A included: fever, normal or count decline of white blood cell and blood eosinophilic granulocyte, half of the patients had rising aminotransferase and were sensitive to diverse antibiotics, especially to fluoquinolones, aminoglycoside, the third generation of cephalosporins and Chloromycetin, the sensitive rates of them were higher than 90%, among them, the sensitive rates of Lavo-Ofloxacin, Butikacin, Gentamicin and Ceftazidime were 100%. Average course of treatment and defervesce was 10 and 5.4 days respectively.

结果：89例患者均有发热，血白细胞正常或减少，嗜酸粒细胞减少，50%有转氨酶升高、对多种抗生素高度敏感，尤其喹诺酮类、氨基糖苷类、头孢三代(头孢他啶、头孢曲松、头孢噻肟)及氯霉素敏感率大于90%，其中，左氧氟沙星、阿米卡星、庆大霉素、头孢他啶敏感率为100%，平均疗程10 d，平均退热时间5.4 d。

A gold immunostrip for rapid detection of Chloramphenicol was developed based on competitive immunochromatographic assay. And the mixtures of saccharose, dextran, polyvinylpyrrolidone, polyethylene glycol, bovine serum albumin, tween20 and antiseptic, etc, as protectants were designed and prepared. Different part of the strip was treated with the protectants, and then thermo-stability of the strip was investigated with storage at 4℃, 37℃ and 60℃.

根据竞争性金免疫层析法原理，研制了氯霉素速测金标试纸条，并选择了蔗糖、葡聚糖、聚乙烯吡咯烷酮、聚乙二醇、牛血清蛋白、表面活性剂Tween20、防腐剂等物质，采用经验尝试法配制了一系列的配方，对试纸条不同部位进行处理，通过37℃和60℃下热稳定性测试，并与未经稳定剂处理的对照进行比较，筛选出适宜的试纸条保护剂。
